[QUOTE="Richard L, post: 965292, member: 52972"] KL, Fly-by-wire only causes a delay in acceleration, not a reduction in HP. The manufacturers are getting better at making the fly-by-wire more responsive by eliminating the delay. Also with a 3 cylinder engine, you probably don't want to shut down any cylinders. Turbocharging is free energy from the exhaust heat and has always been an excellent way to boost HP. With a properly sized turbo on a small engine you can get very good gas mileage and brisk acceleration. I'm sure it will not be a race car, but we are talking about a car designed to get 50+MPG...not zero to 60MPH in 3 seconds. I suspect that the first transmissions would be a 6 speed manual and perhaps a 4-5 speed automatic... Later they may switch to a CVT as they have been proven to work well with small fuel saving engines in small, light weight cars. ...Rich [/QUOTE]
