Lexus LS IV 460 V8 (381 Hp) Super ECT
Overall Rating
Lexus LS:
The Lexus LS is a series of full-size luxury sedans that have served as the flagship model of Lexus, the luxury division of Toyota, since 1989. For the first four generations, all LS models featured V8 engines and were predominantly rear-wheel-drive. In the fourth generation, Lexus offered all-wheel-drive, hybrid, and long-wheelbase variants. The fifth generation changed to using a V6 engine with no V8 option, and only one length was offered.
As the first model developed by Lexus, the LS 400 debuted in January 1989 with the second generation debuting in November 1994. The LS 430 debuted in January 2000 and the LS 460/LS 460 L series in 2006. A domestic-market version of the LS 400 and LS 430, badged as the Toyota Celsior , was sold in Japan until the Lexus marque was introduced there in 2006. In 2006 , the fourth generation LS 460 debuted the first production eight-speed automatic transmission and an automatic parking system. In 2007, V8 hybrid powertrains were introduced on the LS 600h/LS 600h L sedans....(Read more on Wikipedia)
IV Overview:
Lexus LS (IV). With 500 Nm of torque, it offers ample pulling power. With a weight of 2000 kg, it falls in the mid‑range. Rear‑wheel drive offers dynamic handling and sporty feedback. Acceleration is excellent (0–100 km/h in 5.7 s). The top speed reaches 250 km/h. A four-door car with a separate trunk, ideal for families and daily commuting. Seating for 5 makes it ideal for daily use.
The Lexus LS IV (XF40) generation was not directly tested by Euro NCAP. However, Lexus vehicles typically feature robust safety structures and comprehensive active and passive safety systems for their segment.
460 V8 (381 Hp) Super ECT Verdict:
Performance Verdict
The most potent non-hybrid V8, delivering strong 381 Hp and impressive acceleration. The RWD setup allows for a slightly more dynamic feel and better 0-100 km/h times, making it a spirited performer for its class.
Fuel Economy
Achieves slightly better fuel economy than its AWD counterpart, around 11.1 l/100 km combined, due to less drivetrain loss. Still a V8, so expect premium fuel costs.
Pros and Cons:
Pros:
- • Exceptional ride comfort and cabin quietness
- • Legendary Lexus reliability and build quality
- • Smooth and powerful V8 engines, including an advanced hybrid option
