Video: The tech underneath Lexus' new LC 500h is impressive, but it's also very complex. Two separate but interconnected gearboxes -- a dnyamically adjustable CVT and a four-speed automatic -- are the most straightforward parts of this extremely high-tech sportscar's engine and transmission setup.
The LC500h, launched at the Geneva Motor Show, pairs a 220kW 3.5-litre V6 petrol engine with a 44kW electric motor and lithium ion battery pack, all simultaneously delivering drive to the car's rear wheels. Doing that through two extremely different methods of power creation -- a linear electric motor that delivers instant torque from zero RPM and that tails off at higher rotational speeds, and a comparatively peaky V6 petrol motor -- takes a lot of engineering. Here's how it works.
