GM considering new powertrain options for large SUVs

Aside from the new General Motors offerings, there's not a whole lot of action going on in the fullsize SUV segment. That doesn't seem to be stopping GM from pushing the envelope in the market as Automotive News is reporting that the automaker is looking to introduce some new powertrain options into the Chevy Tahoe (and Suburban), GMC Yukon (and Yukon XL) and the Cadillac Escalade - all have been redesigned for the 2015 model year.
Now, we already know that GM and Ford are collaborating on nine- and ten-speed transmissions for a broad range of applications (including the big SUVs), but this new report says that GM is also considering other options as a way to one-up the competition and, of course, to optimize fuel economy. AN quotes Jeff Luke, executive chief engineer for GM trucks, as saying that "interesting powertrain technologies" are coming including a return of a hybrid SUV and possibly even a diesel engine. Although it sounds like the latter could come down to how customers respond to the 2014 Jeep Grand Cherokee EcoDiesel.

Cadillac teases camo'd ELR ahead of Detroit debut

With the 2014 Cadillac ELR being introduced next week at the Detroit Auto Show, General Motors has revealed another picture of its luxury range extended electric vehicle. Last month, we saw a dark, teaser photo showing some of the body detail for the electric coupe, but this recent photo shows the Cadillac in full camouflage testing in California back in September.
If this car looks familiar, it's because our spy shooters got a jump on GM by catching the car in action and providing pictures from all angles. There are still no official details for the ELR yet aside from the fact that it will share the Voltec system with the Chevrolet Volt, but we'll finally see the car unveiled in Detroit a week from today.

First Cadillac ELR rolls off the line

Gearing up for the Belle Isle Grand Prix this weekend, General Motors invited some of the Chevrolet and Cadillac racecar drivers out to its Detroit-Hamtramck assembly plant. While there, the racers - including IndyCar Driver and Chevrolet Volt owner, Simona De Silvestro - witnessed the very first 2014 Cadillac ELR to roll off the assembly line.
These vehicles are not destined for customers, however, but instead pre-production units will be used by engineers for testing purposes. Actual production of ELR consumer models is expected to commence closer to the end of this year. As a refresher, this range-extended electric Cadillac shares much of its powertrain with the Volt but will have a sportier coupe design inspired by the Converj Concept. De Silvestro manged to snap a few images of here own, which you can see in the gallery below.
