Continuously variable transmission

Continuously variable transmission [ e ] The continuously variable transmission ( CVT ) is a transmission in which the ratio of the rotational speeds of two shafts, as the input shaft and output shaft of a vehicle or other machine, can be varied continuously within a given range, providing an infinite number of possible ratios. The continuously variable transmission should not be confused with the power split transmission (PST), as used in the Toyota Prius and other hybrid vehicles that use two or more inputs with one output, despite some similarities in their function. A CVT need not be automatic, nor include zero or reverse output. Such features may be adapted to CVTs in certain specific ...

Lexus RX 400h Car review by Jason Dawe

Building on lessons learnt by Toyota, maker of the Prius, Lexus launched the RX 400h in 2005 for 4×4 drivers who wanted the safety and convenience of an off-roader but didn’t want to offend their green neighbours. With it, 4×4 drivers could glide through the city using only electric motors for emissions-free motoring at speeds up to 20mph. The world’s first 4×4 hybrid, its secret lies beneath the rear seats, where an array of batteries holds power for two electric motors — one each for the front and rear axles. Under the bonnet, where you’d typically expect a large V8 engine, is instead a 3311cc V6. Lexus, Toyota’s luxury subsidiary, claims this petrol-electric combination ...

lsquo;THE OTHER HYBRID’ Car and Driving ‘s Independent New Review of the Lexus GS 300h . Ten Second Review The Lexus GS series hasn t exactly been a nailed-on cert in the executive saloon sector, with the likes of the Audi A6, the BMW 5 Series and the Mercedes E Class to contend with. The latest GS 300h hybrid poses some questions on running costs that have the German establishment looking very uncomfortable. Background Don t mention the d-word at Lexus. Lexus doesn t do diesel. It flirted with diesel power rather unconvincingly in the IS compact executive models but the company is now firmly convinced that petrol/electric hybrids offer all the benefits and none of the downsides ...

The CVT gearbox a love hate relationship Our Cars Honest John

The Details Hybrids have traditionally come with a CVT gearbox — the old ‘rubber band’ transmissions that most people associate with the DAF 55. They may sound old fashioned but they make a lot of sense. Continuously variable transmissions are good for fuel economy as they allow the engine to run at the most efficient revs, an ideal gearbox choice for a hybrid then. Toyota and Lexus hybrids have always used CVT gearboxes and the GS450h is no exception. Obviously it’s a bit more sophisticated than the old DAF 55 version but the theory is still the same. I have to admit that despite the advantages a CVT offers I’ve never been a big fan of them, whether in hybrids ...

2008 Lexus RX400h Review Lexus-quality with fuel economy that doesn’t sacrifice power. Reviewed by Automotive on 12/20/2008 Overview The 2008 Lexus RX400h sport utility vehicle (SUV) is a midsize crossover hybrid. Utilizing a combination of a gas motor and up to three electric generators, the RX400h doesn’t have the fuel economy that is typical of a hybrid, but does well for its class without sacrificing performance or towing capacity making for an interesting option that appeals to upscale environmentally-conscious buyers. This is essentially an RX 350 with better fuel economy, and while it won’t run with class leaders in sportiness, it offers Lexus comfort and luxury while easing ...

Lexus IS 300h brings luxury and economy to the table Lexus has never been scared of taking on the big German luxury car makers. Its big saloon, the LS, makes a strong case for being the most luxurious car on the planet. But is Lexus the luxury arm of Toyota biting off more than it can chew by taking on the mighty BMW 3-Series? The IS compact saloon range starts at 26,495 for the 2.5 litre V6 in SE guise. Unlike its German rivals, Lexus has chosen to push hybrid petrol/electric engines instead of diesel power. The IS 300h starts at 29,495 for the SE, and the top spec Premium model I drove cost 38,495. The entry version of the hybrid returns 65.7mpg and emits just 99g/km of CO2, making ...
