St. Catharine’s Produced GM 3.6L Direct Injection V-6 Engine Makes Ward’s North American ‘Ten Best Engines’ List

The 3.6L V-6 VVT with direct injection in the Cadillac CTS recognized for second year for delivering fuel efficiency and performance




Oshawa, Ontario. – General Motors’ 3.6L direct injection V-6 VVT has been named to Ward’s AutoWorld magazine’s 2009 “Ten Best Engines” list for North America.  Produced at GM Canada’s St. Catharines powertrain facility, the engine is part of GM’s overall strategy to equip vehicles with advanced propulsion technologies that improve fuel economy and reduce emissions.

This is the second year that the magazine’s editors have recognized this engine, which is in the 2008 Cadillac CTS – Motor Trend’s 2008 Car of the Year – and six other GM models. The award will be presented in January at the North American International Auto Show.

“We are pleased that the results of our green by design transformation are being recognized,” said David Paterson, vice president of corporate affairs for GM of Canada.  “Results like these reflect the aggressive focus we’ve paced on improving fuel economy and reducing vehicle emissions through advanced engine and transmission technologies.”

GM’s 3.6L V-6 engine with variable valve timing and direct injection technology is one of the most fuel-efficient in GM’s high-feature engine family, delivering a 3-percent fuel economy improvement over its predecessor.  The 2008 CTS, when equipped with the 3.6L V-6 VVT with direct injection and six-speed automatic transmission, consumes just 7.5L/100 km highway and 10.1L/100km combined.  

The application of direct injection also reduces cold-start hydrocarbon emissions by 25 percent.  With direct injection, fuel is sprayed directly into the engine cylinder, where it is mixed with air. As the fuel vaporizes in the cylinder, the air and fuel mixture is cooled. This enables the use of a higher compression ratio, which improves engine efficiency and performance.

In addition to the Cadillac CTS, the 3.6L DI V-6 engine is available in the 2009 Buick Enclave, Cadillac STS, Chevrolet Traverse, GMC Acadia, Saturn Outlook and Saturn Vue 2-Mode Hybrid.

Why does my 2009 chevy malibu have an 3.6l dohc v6 vvt sfi engine and only gets 18.5 miles per gallon. The first 3,000 miles it was getting 12 miles to the gallon. My feelings there may be a wrong trans or rear end. Any comments. General Motorss is ajoke when you complain. They had to buy back my 2009 Buick enclave due to major problems. This is my last General motors car.

I have a 2015 Impala and my 3.6 has been getting 26-27 in town and when we went on a long trip at Christmas we got 32 mpg. I am so happy with this motor and with 305 hp

My 2015 3.6 Impala, has Mobil 1 synthitic oil in her, I had filled her up with Amaco 89 ethonal free gas and set out on a MPG mission. Granted I babied it, no fast starts nor stops, ran with the cruise control set at 66 MPH and no A/C for a 173 mile trip.

To be honest I don’t think I hit the brakes more than twice on the trip as it was very early morning and no traffic headed north in Wisconsin. I got 35.2 MPG my all time record high.

With the A/C on and plugging along at 70 to 75 I still get 25 ish.
Not bad at all for driving the Battelstar Galactica lol
