Saturn Sky Reviews- part 2


Saturn Sky Road Test

The Sky borrows parts and pieces from GM products around the world, including a set of bucket seats from a Mexican Chevrolet model, driveshaft and differential from the Cadillac CTS, a manual transmission from the Chevrolet Colorado, door panels from the Pontiac Solstice, and a glovebox door from the Chevy Cobalt, none of which should be of consequence to a prospective buyer because the designers and engineers have done such a good job of turning all those parts, with appropriate tweaks, into a Saturn Sky.

We have been trying to like the GM Ecotec engines for years, with few positive results. The 2.4 version is undersquare (a bigger stroke than bore), with a very high power peak of 6600 rpm, and that means you have to wind it up through the gears to have any fun with the car, and that winding produces loud, thrashy noises under the hood which we find not much fun to listen to shift after shift. The noise problem extends to a low, somewhat blatty exhaust note as well. If you stay out of the throttle all the time, we think you'll still have difficulty reaching EPA's estimated highway mileage of 28 mpg. In short, it's not a free-revving engine such as the one found in the Mazda Miata.

The engine, mounted longitudinally in the chassis and leaned over at a 10-degree angle, has electronic throttle control, variable valve timing and most of the other modern conveniences, but it just doesn't make enough power or torque down low where you need it. The clutch actuation was fine, and the fat little short-throw shifters in our test cars were smooth and slick with a little bit of notchiness here and there.

The handling capability of the Sky is very, very good, with an eight-foot wheelbase and a five-foot track width, 53/47 front/rear weight balance, and four meaty 245/45-18 tires supporting its nearly 3000 pounds of weight. We thrashed the Sky heavily on some California wine country mountain twisties, and it was wonderful fun to toss around, far better than we expected. Saturn says the Sky will pull 0.9g on the skidpad, which is world-class for a car in this price class. The steering is pretty accurate and nicely weighted. The ride quality is what you would expect from a short-wheelbase car with big, fat heavy tires and wheels, smooth and pleasant on good pavement, but a bit harsh on railroad tracks and bad pavement.

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.

I got this useful review from www.usedcarschannel.com
