The article says "It acts as a continuously variable transmission (CVT) but with a fixed gear ratio."
This does not make a lot of sense. Since it is a variable [speed] ratio transmission (engine to wheels) it does not in any ordinary sense, have a fixed gear ratio. It is a three way torque ratio device, based on a two stage fixed ratio geartrain ie planetary gearbox.
Regardless the result is fantastic. I havent had a company car for 15 years, and having the opportunity again, I discovered the choice is a lot more complex than the old Mondeo or Cavalier decision. I had an IS300h on trial for a week, and after finding myself within minutes with a big smile and doing 100 alongside the river down at Monmouth, and attempting to drift around corners, I decided that I would thoroughly enjoy driving this car around the south of England for the next 4 years. It doesnt have surge, or a manly roar. I can live without those for the majesty of a chauffeur like ride regardless of what I choose to do with the accelerator. Its plenty quick enough for normal driving, the steering and ride are sublime, the noise level minimal, the bling free interior is a relief, and the exterior lines and the steering wheel finish are perfection.
Besides, my job is as an inverter applications engineer. How could I not drive the car that is exemplifies the possibilities of the inverter so excellently!
