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.

Chrysler, Nissan looking into claim that their cars are industry's most hackable

A pair of cyber security experts have awarded the ignominious title of most hackable vehicles on American roads to the 2014 Jeep Cherokee, 2014 Infiniti Q50 and 2015 Cadillac Escalade.
Charlie Miller and Chris Valasek are set to release a report at the Black Hat hacking conference in Las Vegas, Automotive News reports. The two men found the Jeep, Caddy and Q50 were easiest to hack based not on actual tests with the vehicles, but a detailed analysis of systems like Bluetooth and wireless internet access - basically, anything that'd allow a hacker to remotely gain access to the vehicle's systems.
Considering this lack of hands-on testing, the pair acknowledge that "most hackable" could be a relative term - they point out that the vehicles may actually be quite secure.

Hear the new Cadillac CTS-V torture some tires

The 2016 Cadillac CTS-V seems like the type of wonderful gift that Santa might cook up in his workshop for one extraordinarily good boy or girl. However, the first chance for most people to actually see the super sedan and its carbon fiber pieces in real life is at the 2015 Detroit Auto Show in January. As a stocking stuffer until then, Caddy has released this video highlighting the latest V-Series roasting its tires better than any dinner for the holidays. With the supercharged 6.2-liter V8 from the Chevrolet Corvette Z06 nestled into the CTS-V's engine bay, the Cadillac certainly has quite a bark coming from its exhaust. The mill might be detuned slightly from the 'Vette to 640 horsepower and 630 pound-feet of torque, but that's still plenty for this smoky application. Enjoy this tease of the future V-Series, ahead of the Detroit show.
