DI FTW: GM unveils new direct-injection 2.4L EcoTec and 3.0L V6

Filed under: Crossovers/CUVs, Chevrolet, GM

Well, that was short lived. Ford just finished bringing its more powerful and efficient four- and six-cylinder engines to market in the Escape CUV, but the Dearborn CUV is going to have to kiss its crossover efficiency crown goodbye when the 2010 Chevrolet Equinox drops. Redone for '10, the new Equinox will offer direct-injection engines that deliver greater power and fuel economy improvements of their own, enough to push Ford's new powerplants out of the top spot.

This evening GM has unveiled a 2.4-liter direct injection EcoTec four-cylinder that will kick out 180 horsepower while returning a projected EPA highway rating of 30 mpg (Ford's 2.5L I-4 produces 170 hp and returns a maximum of 28 mpg highway). It's a marvelous way to send the old 3.4 liter V6 into the sunset, but if you absolutely must have a V6, there's also a DI 3.0-liter version of GM's excellent "high feature" V6 delivering an impressive 255 horsepower (Again, Ford's heavily revised 3.0L V6 produces 240 hp).

Both engines have been developed with an eye (or ear) toward reducing the typically increased noise of DI engines. There are rubber isolators to keep the fuel rail racket down and attention to noise attenuation was an important aspect of the program. Variable valve timing also allows both engines to be more efficient over a broader rpm range. Backing both powerplants is a six-speed automatic transmission. Now all the General has to do is hang on 'till these cars hit showrooms and pray for higher fuel prices to further drive demand.
