The Chevrolet Impala is a full-size car that was built by the automobile manufacturer General Motors under the Chevrolet automobile brand in the USA with interruptions from 1958 to 2020 in the USA. Initially, the Impala was the luxury version of the Bel Air model and thus the top model. With the introduction of the Chevrolet Caprice in 1966, it became the middle equipment variant. From 1976, after the Bel Air was discontinued, it was Chevrolet's cheapest offer in its vehicle class until 1985. From 1994 to 1996 and 1999 to 2020 the Impala was again the top model.

The name can be traced back to the African antelope species , which can also be found in the logo of individual model years.

Model history

Impala (1958)

1958 Chevrolet Impala 2-door

The 1958 model year was to be launched on the market in 1957. However, since the development was delayed, it started as a 1958 model year and remained in the program for only one year. In the previous model years, as with all other makes and models, the front had single headlights. With the introduction of the Cadillac Eldorado Brougham , the manufacturer introduced twin headlights in 1957. For this, however, the US licensing law had to be changed. All manufacturers, including Chevrolet with the 1958 Bel Air and Impala models, followed suit.

Impala / Impala SS (series 1300/1400/1700/1800, 1959–1964)

In the 1959 model year there were two Bel Air models, a two-door hardtop sports coupé with no B-pillar and a two-door convertible with the additional designation Impala . They were built on the GM-B platform, had an X-shaped frame with double wishbones , individually suspended wheels at the front and a rigid axle with trailing arms and a panhard rod at the rear.

With the 1959 model year, all vehicle shapes changed. The opulent tail fins became smaller and the massive bonnets merged flatter into the fenders.

In 1959 it became its own series that replaced the Bel Air as the top model. The much flatter bodies with a longer wheelbase had a radiator grille with integrated double headlights across the entire width of the vehicle and characteristic wing- shaped tail fins at the rear , under which lens-shaped taillights with three chambers were arranged. The Biscayne became the entry-level model and the Bel Air took the middle spot. The Impala with a six-cylinder engine was called the 1700 series, the V8 models were called the 1800 series . In addition to a four-door sedan, there was a two-door convertible, a two-door hardtop coupe, a four-door hardtop sedan and a five-door station wagon. The latter had six seats and its name Nomad was taken from the corresponding Bel Air model.

1700 had a six-cylinder in-line engine with 3859 cc capacity, the at 4000 min ^-1 gave an output of 135 hp (99 kW). The 1800 had a V8 with 4,637 cc displacement and an output of 185 hp (136 kW) at 4,600 min ^-1 , but either there were more powerful engines:

Type	Displacement	compression	Carburetor	Exhaust	power	at speed

Special Super Turbo-Thrust V-8	5703	11.0	3 × double	Double	315/232	5600

In 1960 an SS ( Super Sport ) package with more decoration was offered as an optional extra. It was initially only available with the powerful 5.7-liter V8 engine. The Impala immediately became the best-selling Chevrolet model. The bodies were streamlined and the lens-shaped taillights gave way to three round ones on each side. In 1960, the Impala was the top-selling car in the United States and held that position for a decade. Between 1957 and 1996 over 13 million Impala were sold - a record for American full-size cars.

In 1961 a facelift followed , which left only hints of the rear wing. The engine range was expanded to include a V8 engine with 6702 cm³ displacement and 360 hp (265 kW) output (for the Impala SS). The other engines also gained in power. A two-door sedan and a nomad station wagon with nine seats were added as new models

In 1962 the Chevy II was introduced in the lower middle class , so that the three models Biscayne, Bel Air and Impala represented the upper half of the Chevrolet range. The 6.7-liter V8 engine achieved a new record with 409 hp (301 kW). The Impala SS was now available with all engines of the "normal" Impala. The two-door sedan was no longer offered and the two station wagons were now called Impala Station Wagon .

In 1963 there were almost only external changes, but the engine output of the 6.7 liter V8 engine increased to 425 hp (313 kW) and a V8 with 6997 cc and 430 hp (316 kW) was also available.

In 1964 the front was redesigned with a slightly lower grille and the rear. The Impala SS was introduced as a separate series and was given the numbers 1300 (six-cylinder engine) and 1400 (V8 engine). It was only available as a two-door hardtop coupé and a two-door convertible.

The Impala (especially the 1963 and 1964 models) has achieved cult status in certain circles, as it is often used as the basis for building a Lowrider .

Impala / Impala SS (series 163/164/165/166/167/168, 1965-1970)

4th generation
Chevrolet Impala Custom Series 164 (1968)
Production period:	1965-1970
Body versions :	Sedan , coupe , convertible
Engines:	3.9–7.0 liters (103–313 kW)

Height:	1382 mm
Wheelbase :	3023 mm

The Impala (like the Biscayne and Bel Air) was presented in the 1965 model year.

The cars were flatter, wider and longer. The nose with the low grille , which also extended below the bumper, formed a flat V, the point of which pointed forward and upward. There was a slight hip bend over the rear wheel cutouts. There was the familiar six-cylinder in-line engine or a new cc with 4097 capacity , which at 4200 min ^-1 developed an output of 155 hp (114 kW). The six-cylinder models were now called the 163 series , while the V8 models were called the 164 series . The Impala SS was also continued . The six-cylinder models were called the 165 series , while the V8-powered cars were grouped together as the 166 series . With them there was a new engine with 6489 cm³, the 325-425 HP (239-313 kW) made. In 1965, the Impala set an industry record with over a million units sold, which is still there today.

In the following year there were only minor retouching, such as additional chrome strips on the headlights. For the 1966 model year, Chevrolet introduced the Caprice as the new top model; from this point on, the Impala ranked as the middle model series between Bel Air and Caprice. Since the Caprice was given the serial number 166, the Impala SS mutated to the Series 167 (six-cylinder engine) or Series 168 (V8 engine).

In 1967 the front indicators moved to the corners of the vehicle and formed a clear contouring of the front of the vehicle with the V-shaped nose. The hip bends over the rear wheel arches became more noticeable. In 1968 the front indicators became smaller again and made room for a front bumper that was clearly pulled upwards. The double headlights received rectangular, chrome-plated frames. A two-door coupé (with B-pillars) was added as a new model. A 1967 model year Impala can be seen in the television series Supernatural .

The Impala SS was no longer a separate series from 1968, but sank back to the status of an equipment package that could be ordered for every Impala. Only the sedan and the two hardtop models were available with six-cylinder engines. Technically, little changed in these two years.

There was a Z24 equipment package that was supplied in conjunction with the regular Super Sport package (order code Z03). From 1967 to 1969 the Impala with the Z24 package carried “SS427” emblems. The SS427 received a sports suspension and other performance goodies, as well as the turbo-jet 427 engine with 7 liters displacement in different versions (L36 or L72). However, this full-size high-performance automobile did not sell particularly well because the performance- hungry fans tended to opt for mid-range models with powerful engines, such as the Chevrolet Chevelle SS396 or the Plymouth Road Runner with Hemi engine, which were lighter and correspondingly faster. Interestingly, the Z24 package was also available without the SS package, that is, with a front three-seater bench.

The SS427 from 1967/68 had special hoods with a hump, the 1968 model also had "gills" on the front fenders, reminiscent of the Chevrolet Corvette .

The series was revised again in 1969. With the same wheelbase, the cars were even longer and wider. The even more strongly contoured front had a striking chrome frame and the rear wheel cutouts had been reduced so much that the upper halves of the wheels were almost covered. The lower half of the rear end was taken up by the chrome-plated rear bumper, which also accommodated the three narrow taillights on each side. The station wagons - only available with V8 engines - were now called Kingswood . This year, the only Super Sport was the SS427 with 390 hp or 425 hp and standard front disc brakes and larger 15-inch wheels. It was to be the last Impala SS by 1994.

There were few changes in 1970. The engine program streamlined: In addition to the well-known 4.1-l six-cylinder engine, there was a new V8 engine with a displacement of 5735 cm³ and 250 hp (184 kW). Only two models were available with six-cylinder engines: the sedan and the hardtop coupé; the four-door hardtop sedan was only available with a V8 engine.

In 1971 a newly developed full-size series came out. The combination models of the Impala were still called Kingswood. The wheelbase of the sedans, coupes and convertibles had grown by 2½ ″ (63 mm), and in the case of the station wagons by 6 ″ (152 mm). The massive, strongly contoured front featured a low radiator grille and indicators again on the corners of the vehicle. All big Chevrolets got disc brakes on all four wheels. The engine power sank by 5 HP each.

Chevrolet Impala Cabriolet Series 164 (1971)

A slight redesign of the front of the vehicle made the radiator grille shrink in height in 1972. The wheelbase of the sedans, coupes and convertibles increased again by ½ ″ (13 mm). From this year on, the engine performance was given in net horsepower (nhp). The most powerful V8 engine had a displacement of 7440 cm³ and developed 270 hp (199 kW). The new model designation was uniform for the six and eight-cylinder 1M series this year .

After the Biscayne was no longer offered in 1973, all full-size model series slipped down one place: the entry-level model was the Bel Air, the Impala took the middle place and the Caprice was the top offer. Accordingly, the Impala inherited the designation Series 1L from Bel Air. The station wagon models were again called Impala Station Wagon, the hardtop coupé and the convertible had been deleted from the range. There were two coupé models for this, one "Custom" and one "Sport". The front and rear of the cars have been slightly redesigned and are a little longer. The performance of all engines fell by 10–20 nhp as a result of the oil crisis . The six-cylinder had been dropped. In 1974 there were no changes, except for a slightly redesigned front mask. In 1975, catalysts were introduced. A "Landau" was added as the third coupé variant. Otherwise there were few changes.

In 1976 the Bel Air also dropped out of the upper middle class model range. This made the Impala the entry-level model for the big Chevrolets. The sports coupé was no longer available, instead there was an S version and a sports version in addition to the normal four-door sedan. The cars were - together with the more luxurious Caprice Classic - run as Series 1B . The front view was once again slightly revised and now showed a narrower radiator grille set prominently to the front, flanked by double headlights in rectangular chrome frames. V8 engines with 5735 cm³ and 165 PS (121 kW), 6554 cm³ and 175 PS (129 kW) or 7440 cm³ and 225 PS (165 kW) served as drive.

In the smaller generation of the large Chevrolet introduced in 1977, the Impala again played the role of the base model (except in Canada, where a Bel Air model, which had been abandoned in the USA, was marketed under it until 1980).

In 1985 the name Impala was dropped.

Based on the new Caprice introduced in February 1990 on the traditional GM B platform , there was an Impala SS for the first time since 1969.

At the Sema Show in November 1992 was the concept vehicle of an Impala SS, which was designed under the direction of the Chevrolet Special Vehicles board member Jon Moss and which was well received by the press and the public. About 15 months (February 1994) after the trade fair, the Impala SS went into series production at the factory in Arlington, Texas .

From a technical point of view, the “Impala SS” from model years 1994–1996 is a Caprice that carries a “personality package” with the option code WX3 (Merchandised Trim Package, Impala SS). Unlike the Impalas of the past, the WX3 is neither a trim level nor its own series, which often leads to identification problems, since the correctly read out chassis number of a WX3 does not identify it as an Impala SS, but as a Caprice. The WX3 package not only includes SS-specific technology, but also the "optics package" BA5, which gives the Impala SS its characteristic appearance.

BA5 contains, among other things, the elimination of the Caprice hood ornament, the Impala emblems, the special radiator grille, the decorative strips and the rear spoiler of the SS, the gray leather interior with headrests integrated in the front seat backrests, aluminum wheels measuring 17x8.5 with P255 / 50ZR17 -Tires and the lettering on the rear side panels. The cars had ventilated disc brakes on all four wheels, stiffer coil springs and DeCarbon shock absorbers.

An easily overlooked detail of the BA5 package is the trim strip on the upper front edge of the main headlights, which is made in the respective exterior color.

For 1994, the only available exterior color for the WX3 was black (BBB). That year, 6,303 vehicles were sold starting at $ 22,495. In 1995 Dark Cherry Metallic (DCM), used for 7,134 vehicles, and Dark Green Gray Metallic (DGGM) with 4,442 vehicles were added. As in 1994, black was painted 9,858 vehicles. The price rose to $ 22,910 for this model year vehicles. The color palette did not change in the 1996 model year, but sales nevertheless increased. 19,085 vehicles in black, 12,180 in dark cherry and 10,676 in dark green were sold. Medium Marble Metallic (MMM) was intended for the 1997 vintage, which was never produced. All Impala SS are equipped with the MPFI-5.7-liter V8 engine called LT1 with 194 kW, the only transmission being the 4L60E automatic transmission with four gears.

The Impala SS is not to be confused with the Caprice LTZ, which was available on the American and European markets from 1991 to 1993 and in the Middle East from 1991 to 1996. The LTZ were Police Package (9C1) vehicles with civilian interiors without any significant external features. The B4U package for the Caprice (1994–1996) is also referred to as the “sports package”, but it is actually a technology package that civil vehicles had to be supplemented with if they were equipped with the MPFI-5.7, which was optional from 1994 -Liter engine (LT1) were ordered. Almost the same as the WX3 is the WX8, which from 1994–1996 was only sold in the Middle East instead of the WX3 under the name "Caprice SS". WX8 have no catalytic converters and are designed for leaded gasoline. The only other distinguishing features of the WX8 are “Caprice SS” lettering on the rear side panels and on the dashboard - the WX8 also bears the Impala logos of the WX3 - and the door stickers are in Arabic.

On the technical side, contemporary reporters in particular have said that the WX3 is directly related to the Caprice Police Package (9C1), and the MPFI-5.7-liter V8 (LT1) has a technical similarity to an engine from the Corvette, which has the same Option code carries. Both are largely wrong: The WX3 shares the rear brakes and the external engine oil cooler with the 9C1. The WX3 has not adopted all other essential components of the 9C1 package, namely the "Cross Stamp" frame, the "Police" chassis (7B3), the converter configuration and forced downshift capability of the 4L60E transmission. The WX3 share the frame with the civil version, while the WX3 chassis is completely Impala-SS specific and includes its own DeCarbon shock absorbers, shorter, specific springs, different bushing material and the rear axle of the Wagon series. Unlike the civil versions of the Caprice equipped with the LT1, the WX3 was not delivered with the new 2.93: 1 rear axle drive, but retained the 3.08: 1 ratio, which in the years 1991-1993 was in the middle between the traditional 2, 56: 1 and 3.42: 1 axes covered. The slip-reduced differential (G80) was only standard on the WX vehicles.

The engine of the WX3 has a generation 2 block - a further development of the small block Chevrolet V8 (SBC) used in series from 1955 to 2002. These "Two Gen" engines were only available from 1992 to 1997 in a total of six different configurations, three in the Caprice, two in the Corvette and one in the Camaro. "LT1" identifies the vehicle-specific standard 5.7 liter. In fact, the vehicle-specific LT1 in the Caprice and the Corvette neither share the block, nor the heads, nor the camshaft - their relationship mainly consists of the “two-gen” layout, which includes the “backward” cooling circuit and the shaft-driven water pump . The main distinguishing feature (in addition to the mirror-inverted belt drives) are the cast iron cylinder heads of the Caprice-LT1 - the Corvette-LT1 have aluminum heads.

Due to delivery problems on the part of the rim manufacturer, the WX3 were initially produced in an unintentionally limited number - after the 6303 black Impala SS of the 1994 model year, production had to be interrupted. From the 1995 model year, the plastic insert on which the Impala logo was attached to the foot of the C-pillar was incorporated into the body sheet of all Caprice. Like all Caprice, the WX vehicles received new, much larger exterior mirrors that were mounted in the door triangle instead of on the door skin.

There were some changes in the 1996 model year; so the digital speedometer was replaced by an analog one, and the selector lever of the automatic transmission moved from the steering column to the center console. 41 941 copies of the 96 model were sold.

With the discontinuation of the entire B platform and the D platform derived from it in autumn 1996, the Impala SS was also discontinued; production ended on December 13, 1996. The last vehicle produced was bought by Chevrolet collector MG "Pinky" Randell.

A new edition of the Chevrolet Impala (internal designation GMX210) was formally shown for the first time in early 1999 at the North American International Auto Show (NAIAS). The first vehicles were delivered to dealers in April 1999. As a model year 2000 vehicle, it became a replacement for the Chevrolet Lumina , which remained available to fleet customers until 2001. In contrast to the earlier models, this model was no longer a classic American vehicle of the upper middle class, but belonged to the middle class. The vehicle is based on GM's W platform. Instead of eight-cylinder engines, the Impala was only powered by six-cylinder engines (3.4 l and 3.8 l) via the front wheels between 1999 and 2005. The 3.8-liter engine was supercharged in 2004 and the SS version developed a maximum of 179 kW (240 hp). An independently run coupé version of the Impala was also offered, which was also given a traditional name: Monte Carlo .

Furnishing

Buyers had two versions to choose from, the basic model with a fabric-covered front seat, a maximum of 134 kW (180 hp) 3.4-l V6 engine and a dashboard with three round instruments. In the Impala LS, there were front single seats with fabric cover, leather, center console and center selector lever, Impala logos in body color, ABS, traction control, keyless entry, fog lights, 4 round instruments and the 3.8-liter V6 engine with a maximum as standard Output of 149 kW (200 hp). For a surcharge there was a sunroof, rear spoiler, heated and electrically adjustable seats and 16-inch aluminum wheels, the design of which was reminiscent of the Impala SS from 1994-96, for all models. Power windows, central locking and electrically adjustable rear-view mirrors were standard in all versions. From model year 2002 or model year 2003, Chevrolet offered an LS-Sport package, which included 6 round instruments, a front spoiler, a rear light cover painted in the vehicle color and a chrome-plated exhaust end piece.

Impala SS 2004-2005

The Impala SS, formally shown for the first time at the Chicago Auto Show 2003, was powered by the supercharged L67 version of the 3.8-liter V6 engine between 2004 and 2005, which had a maximum output of 179 kW (240 hp) and was already in Pontiac Grand Prix  GTP, used in the Buick Regal  GS and the Pontiac Bonneville  SSEI, was powered. The sedan accelerates from 0 km / h to 100 km / h in around 6.5 seconds. In addition, there was a special edition limited to 4088 pieces in the 2004 model year called the Chevrolet Impala Indy SS.

Sales figures

This generation of Impala was successful in the USA, with around 290 in 2004 alone 259 pieces sold. This made the Impala one of the best-selling large American sedans.

The police package

Like all the big Chevrolets of the last few decades, this Impala was also available with a special police package and also with an undercover police package, code numbers 9C1 and 9C3. These versions were only available to police authorities and were more successful than its direct predecessor, the Lumina 9C1. The Impala 9C1 largely corresponded to the civilian base model, but had the 3.8-liter V6 engine and a reinforced chassis and was only available in selected colors. In addition, the driver could turn off the lights to be less noticeable; this was not possible with the civilian Impala versions as they were equipped with daytime running lights . With the 9C3, extras could be ordered from the regular price list and a larger selection of paintwork and interior colors.

At the beginning of 2005, the vehicle (internal designation GMX211) was formally shown for the first time at the LA Auto Show . A revised version of the mid-size sedan Chevrolet Impala was available from summer 2005. This came up with a newly designed front section and changed front and rear headlights. As part of the facelift, the Impala received a new, optionally available 3.9-l V6 engine with a maximum output of 174 kW (233 hp) and variable camshaft control and cylinder deactivation (Active Fuel Management), the three of the six cylinders in the partial load range turns off. There was also a 3.5-liter V6 engine with a maximum output of 157 kW (211 hp). The same goes for the front-wheel drive and the four-speed automatic transmission (4T65-E). The two six-cylinder engines are E85- compatible. From the 2007 season up to and including the 2012 season, the design of the vehicle formed the model for the racing car used in the NASCAR Cup Series based on the Car of Tomorrow .

Chevrolet Impala LTZ (2007)

The sportier SS model was fitted with a V8 engine for the first time since 1996. Although this traditionally only has two valves per cylinder, it can offer variable camshaft control and cylinder deactivation, which deactivates four of the eight cylinders in the partial load range in order to save fuel. Under full load, this 5.3 l engine develops 226 kW (303 hp) and has 438 Nm at the highest point on the torque curve  .

Several new colors were added to the Impala range for the 2007 model year.

The price list started at $ 22,400 (approx. € 14,000) for the LS and $ 29,780 (approx. € 18,600) for the SS (as of 2008).

The official version with modifications for the task as an emergency vehicle was offered on the basis of the basic model LS and was popular with numerous police authorities in North America. The model is also often used as a taxi, so that fleet customers made up a significant proportion of the buyers.

Facelift

Chevrolet Impala (2011-2016)

The SS model was discontinued in the summer of 2011. At the same time, the V6 engines were also replaced by a single option with 3.6 l displacement, direct injection and a maximum output of 224 kW.

Due to the realignment of the successor model towards the premium segment, the series remained in production as "Impala Limited" until 2016, but could only be ordered by fleet customers.
