What if Chevy made the Spark with the Sonic's Turbo engine. I think that would be a nice performance model to add to the Spark.
What do you guy think about this idea?We were likewise surprised by the 138-hp, 1.4-liter turbo four. It’s a gem, much easier to appreciate here than in the heavier Cruze. There is very little lag, power delivery is smooth, and it never groans in complaint like so many other econocar engines. (A naturally aspirated 1.8-liter four is the Sonic’s base engine.) The Sonic’s 1.4 runs out of breath way before redline, though; the fuel cutoff is at 6500 rpm, but shift by 6000 if you want to keep things moving. We saw 60 mph in 8.2 seconds on our best acceleration run, and we snuffed the quarter-mile in 16.5 at 85 mph. A small engine and an upright body are not a good combo for high-speed runs; the Sonic needs 24.7 seconds to hit 100—although that’s almost as good as it gets in this class.
