Apparently, under certain circumstances when gasoline with lower than the required 91 octane rating is pumped into the 2010 Cadillac SRX with the available 2.8-liter, 300 horsepower turbocharged V6, a "mega knock event" can be induced, leading to a complete grenading of the engine. Not good.
The worrisome issue was discovered by Automobiles De Luxe, which happened to be road testing one of Cadillac's latest 'utes. The driver inadvertently pumped in 88 octane fuel, which led to the aforementioned mega knock event and subsequent destruction of the engine. General Motors says it wouldn't have happened if the correct grade of gasoline had been used.
So, open-and-shut case, right? Better use the premium. Not so fast. GM expedited the vehicle to its test center in Warren, Michigan, tore down the engine and came up with a "new calibration" for the engine's computer that will eradicate the possibility of such an event. Six 2010 Cadillac SRX turbos are being field tested in Death Valley to ensure the problem is solved.

"GM public relations agent Robyn Henderson has confirmed that production of the Cadillac SRX Turbo will cease, authenticating the constant rumors that have been circulation on the Internet for the past few months. That means the SUV will only be powered by the 3.0-litre V6 generating 265 hp and 223 ft-lb of torque in the future."
This is quite interesting given the fact the SRX is selling well. When I test drove the SRX non turbo I deemed it a gutless slug, and while waiting for the turbo version to come out I chose the Q5 instead. Plenty of zip from Audi.
