    "How about this for a Fiesta ST fighter?" How about no? While the 1.6T would be a welcome addition to GM's US engine lineup, I am far less enthused about the hot Corsa. Opel just doesn't seem to have the talent to build great hot hatches - something that has been reflected in the previous attempts that have mainly resulted in overweight, understeering and unrefined cars.

    "what consumers are doing with the gas savings?" Purchasing more Katy Perry songs, that would be my guess.

    And speaking of the ZF-9, I believe this is a case of "one gear too far".

      Agreed. The Chrysler 8-speed is universally praised. Too bad it can't be used in smaller cars.

    How many gears do we need? It seems the most efficient use of the ICE is to set it up as a stationary constant speed unit. It this how we are heading? Sort of like a turbo prop, they are constant speed. Design a car engine that 'idles' at 1 600rpm and revs out to 1 600rpm. Stop at the lights to engine stops. Take you foot off the brake and slam the accelerator and the engine resumes it' 1 600rpm. How exciting! Why are we still looking at wide flat torque bands? With countless gears we only need a torque band of less than 1 000rpm. Yep, constant speed engines.

      @turf3 The parallel hybrid as engineered by Toyota and Ford hardly suffers any complexity penalty. The transmission of a conventional vehicle is replaced by a vastly simpler single planetary gearset. The only addition is a battery and two electric motors. The software is quite complex, but the hardware is amazingly simple. And it's worth noting that the software on the Toyota and Ford hybrids, indeed, doesn't ever fail. They are some of the most reliable cars on the road today, and when there is a propulsion system failure it's almost always hardware: the battery or, occasionally, the ICE.
