Emissions regulations have forced a slight re-tuning for 2008, which has dropped the engine's power peak from 6600 to 5800 rpm; still, it's not a free-revving unit such as the one found in the Mazda Miata. For 2008, EPA-estimated fuel economy is 25 mpg Highway.
The more powerful, more firmly sprung Sky Red Line is much more fun to drive with its 2.0-liter turbocharged Ecotec four-cylinder. This engine delivers 260 horsepower and 260 pound-feet of torque, the latter over a very flexible range of 2500-5250 rpm. Bore and stroke dimensions for the 2.0-liter are identical, so there's less harshness. And there's no turbo lag. The turbo rolls out its power in a smooth, linear fashion, with strong acceleration performance available over a wide range of engine speeds. We've found this engine far more willing for sporty driving than the 2.4-liter normally aspirated engine in the standard model.
Best of all, the 2.0-liter turbo-motor delivers significantly better highway mileage, rating 28 mpg Highway by the EPA. As with the base engine, premium fuel is recommended for maximum performance (but not required).
One of the attributes we like best about the Sky is its powerful, progressive braking, with very little slop at the top of the pedal before deceleration starts. These are big discs brakes for such a small car, and they work very well and very consistently. Next Page
