If current rumors prove accurate, General Motors has big plans for its line of high-feature V6s, and with good reason. These six-cylinder engines make class competitive power and are very smooth. Thanks to direct injection, the engine range also offers excellent fuel efficiency when mated to GM's equally new six-speed automatic transmission. We recently heard that a new 3.0-liter version of this powertrain duo would make an appearance in the new 2010 Buick LaCrosse, and now we're hearing the engine will also be optional in the upcoming Chevy Equinox and standard in Cadillac's new SRX. Expect the new 3.0-liter V6 to offer around 250 horses and fuel efficiency slightly under 30 mpg on the highway. The Equinox's standard engine will be a new 2.3-liter direct-inject inline four-cylinder unit making something north of 200-horsepower, while the uplevel Caddy SRX should get the optional 300-plus horsepower 3.6L powerplant as found in the CTS.
