GM's 3.9-liter V6 with Active Fuel Management (AFM) cylinder deactivation technology will launch in the 2007 Chevy Impala.


GM continues to revamp powertrain lineup, push E85 for 2007 model year

AutoWeek | Published 05/19/06, 9:34 am et

GM has been busy revamping its powertrain lineup. From fuel sippers to turbocharged performers, the automaker is boasting 19 new or revamped engines and transmissions, mostly available for the 2007 model year.

Among the highlights:

>> The first GM V6 engine (3.9-liter) with its fuel-saving Active Fuel Management (AFM) cylinder deactivation technology will launch in the 2007 Chevy Impala. GM also offers AFM on its 5.3-liter V8s. By 2008, the automaker estimates it will have two million AFM-equipped models on the road. AFM-equipped engines will be available in 15 GM models for 2007.

>> A new GM hybrid system for the Saturn Vue Green Line, which improves fuel economy by 20 percent, the automaker says.

>> The 260-horsepower, 2.0-liter turbocharged gasoline direct injection Ecotec four-cylinder powering the Solstice GXP, Saturn Sky Red Line and Opel GT. Its 130 horsepower per liter is the highest of any production engine in GM history, according to the automaker.

>> New six-speed automatic transmission variants for front-, rear- and all-wheel drive applications launch in nearly 40 global models in 2006 and 2007.

And in its continuing push to push E85, the automaker will also offer 14 models capable of running on ethanol for 2007. The company boasts nearly 2 million flex-fuel models already on North American roads.

Let me get this, the Hyundai Sonata gets 21/30 and the new 'fuel saving' engine gets 20/29.
where is the 6t70 in all this? The sonata is already as fast if not faster than the regular 3.9/3.29 axle ratio combo.

The only good GM V6 is the 3.8 3800 series V6. Pushrods, all iron. Those motors are bulletproof. The 3100, 3400 and 2.8 V6's are junk. The 90-93 3.1 MPI V6 was pretty good though.

Wait, GM is adding the 3.6 DOC V6 & 6t70 to the 2007 pontiac G6, and the chevrolet gets the 3.9 DOD/4t65. Real smart move people.

Nice to see that your are contemporary.
the 3.5 of the malibu/G6 is far torque-ier than the 3.5 of the impala

Different engines, the impala is a short stroke 3.9 (99x76) , wherease the 3.5 is a bored 3.4 to 94x84
The 3.9(99x92) now comes in two flavors

GM should just break out the hacksaw, and take off 2 cylinders from the 6.0 LS2 for a nice 330hp 4.5 liter V6, or knock back spark to run on 87 and add cylinder shutoff for an even 300hp. Cheaper than the 4.2 I6, and can be a nice base engine for the Tahoe (Does the I6 fit?)
