Keeping a turbo engine loaded is advantageous because it keeps the turbo spinning, which in turn allows for faster power delivery. In a manual-shifting car, depressing the clutch between gears unloads the engine. The five-speed automatic - the same one in the Cadillac CTS - bangs off quick shifts, and the transmission's torque converter keeps the engine loaded, even between shifts. ![]() The automatic requires only brake torquing (left foot on the brake pedal, right foot on the throttle pedal) and the will to keep the accelerator pegged. Getting the manual version quickly to 60 requires a torturous high-rpm clutch drop followed by careful management of wheelspin and two very fast shifts. Quarter-mile trap speed provides excellent evidence of a car's horsepower claim if our Sky had had an unusually powerful engine, it would have had a higher speed through the quarter.Īside from being quicker, the automatic option makes accelerative tasks easy. But this is unlikely, considering the Saturn hit the quarter-mile at the same speed - 98 mph - as the Pontiac. You might be thinking this particular Saturn was quirky, that it somehow had an unusually strong engine. We would expect a Solstice GXP with an automatic to be the same as its twin, the Sky Red Line. With an automatic, the Sky Red Line hustles its way to 60 mph in 5.2 seconds, a time that betters the manual Solstice GXP's 5.6 seconds. For the price, there is no better deal.Enchanted by the looks of the Saturn Sky Red Line and Pontiac Solstice GXP but not comfortable with a manual transmission? Concerned that the $850 automatic will sap the joy from GM's diminutive roadster? The good news is that, despite the turn-off of an automatic-equipped sports car, the performance numbers of this Sky Red Line should be seriously eyeballed because in our hands it out-accelerates a mechanically identical Pontiac Solstice GXP equipped with a stick shift. This tune gives you the confidence knowing you could beat most cars from a stop light, and really push you back in your seat. It is exhilarating in 2nd, 3rd, and 4th gears. I drive with the tune off the majority of time to conserve fuel, but switch it on when going for a pass, or accelerating onto the freeway. After I got my car back, I flashed it with the tune again and have been enjoying it, although I do watch the revs now. ![]() My car is out of warranty, but before I brought it in to the dealership for repair, I reflashed it back to stock (one of the options included with the software). I don't blame the tune, just the fact that I was running higher revs than normal. I drove my car hard after installing it, and my water pump let go. I selected the tune on/off with the cruise control, and it works good to have a quick switch on the steering wheel (as well as not having an annoying light on the dash if you select the Competition Mode method). I did not have the GMPP upgraded sensors, and they are not needed. Both came quickly(about a week), with good feedback from the seller. I bought the Trifecta Tune for my Saturn Sky Redline, along with the EZ-Flash cable.
