The Lexus UCF20 , sales name Lexus LS400 (Toyota Celsior in Japan), is the second generation of the luxury class car Lexus LS from the Lexus brand belonging to the Japanese automobile group Toyota .

history

Like its predecessor, the car was offered in the USA and Europe as the LS400 - in Japan as the Toyota Celsior . The UCF20 had the four liter big V8 of its predecessor with a slightly to 194 kW (264 PS / 260 bhp = English horsepower) increased power. In addition, the car was 95 kg lighter than its predecessor and therefore both more economical and slightly better in acceleration. The drag coefficient ( ) has been reduced slightly from 0.29 to 0.28. Among the facilities included, among other things, one of the first slot-in - CD changer .

In mid-1995 the car was briefly affected by US tariffs on Japanese luxury vehicles, which drove the sales price from around US $ 51,000 to over US $ 100,000. Nevertheless, 1995 was the best sales year for the second generation, while the model sold significantly worse than both its predecessor and its successor . Total production was around 114,000 vehicles.

In Germany, the car was offered from the spring of 1995 at a base price of 116,400 DM.

Special features on the engine

Toyota 1UZ-FE

The 4.0 L aluminum block 1UZ-FE debuted in 1989 in the first generation of the Lexus LS 400 / Toyota Celsior and was then gradually installed in other Lexus and Toyota models. It is a short-stroke internal combustion engine (oversquare engine) with a piston diameter of 87.5 mm (3.44 in) and a stroke of 82.5 mm (3.25 in).

Special features are:

The similarity of the 1UZ engine to racing engines (6-bolt main bearing / short stroke ratio / special piston configuration) was confirmed in an interview (with v-eight.com) in 2007 by David Currier, Vice President of TRD-Toyota Racing USA. The 1UZ platform is based on IndyCar / Champ Car engines. It was planned to be used in GT500 racing cars - but it was used in the Daytona prototype.

The 1UZ-FE has a compression ratio of 10: 1 and an engine output of 191 kW (256 hp) with a torque of 353 Nm.

In 1995 the engine was redesigned by installing lighter connecting rods and pistons and increasing the compression ratio to 10.4: 1 - the result is 194 kW (264 hp) and 363 Nm.

In 1997 Toyota introduced variable camshaft adjustment (VVT-i) and again increased the compression ratio to 10.5: 1, which improved power and torque (216 kW / 290 PS and 407 Nm). In the Lexus GS400 it is 300 PS and 420 Nm.

Ward's AutoWorld magazine selected the 1UZ-FE as one of the ten best engines in the world from 1998 to 2000.

The engine was installed in:
