2015 Cadillac ATS Coupe favors cleanliness over radical lines

Though you might not know it from looking at vehicles like the XTS and Escalade, if you take a broader look at history, you'll see that Cadillac models have gotten a lot smaller from the tail-finned highway cruisers of old. At least when it comes to coupes, anyway. The Eldorado, in particular, kept getting smaller until it disappeared, its place taken in recent years by decidedly more compact XLR, CTS Coupe and ELR hybrid. What you see here, however, is Cadillac's smallest coupe yet.
Revealed today at the Detroit Auto Show is the new 2015 Cadillac ATS Coupe, the brand's first compact two-door coupe, and the first production car to wear the brand's all-new crest. It shares the same platform and wheelbase as the existing ATS sedan, but packs a wider track and unique bodywork that's decidedly more conservative and less unique in its angular styling than the CTS Coupe that it's likely to ultimately displace in the Cadillac lineup. Styling aside, the all-American luxury marque has engineered the ATS Coupe with a focus on reducing weight to the benefit of both performance and fuel economy, giving it near 50/50 weight balance front to rear with underbody aerodynamic elements helping it cheat the wind.
Buyers will be able to choose between two engines: a 2.0-liter turbo four and a 3.6-liter V6.

Buy a Mosler Twinstar, the V16 Cadillac you almost wanted [w/video]

Cadillac was once famous for opulent, V16 luxury vehicles, but this bizarre 16-cylinder 1999 Eldorado that's for auction on eBay Motors isn't much like its ancestors. Dubbed the TwinStar, this beast features a Northstar V8 with 275 horsepower to drive the front wheels and a second Northstar with 300 hp is in the trunk to spin the rear axle. Each mill has its own four-speed automatic gearbox, and the result is a total of 575 hp of all-wheel drive fury in an incredibly weird package. The TwinStar's interior and exterior certainly don't hide the odd powertrain setup. To fit the engine in the trunk, the builders pushed the rear wheels further back and lengthened the wheelbase. There are also scoops low on each side to funnel air to the V8. Inside, there's a second ignition on the side of the center stack, and a digital instrument cluster replaces the glove box. It's sure to confuse any passenger you can convince to take a ride in this thing. Mosler, the supercar company known for models like the MT900, built five TwinStars, according to the auction. The seller links to the original review by Car and Driver, and the magazine noted that the sensation of the two engines working in tandem was rather odd. However, the TwinStar was a capable performer and ran to 60 in 5 seconds in its test. If you want to start your new year with the oddest vehicle possible, the TwinStar's auction sits at $5,600 with the reserve not met as of this writing, and it ends January 2, 2016, at 8:00 PM ET. If you can't wait that long, the dealer lists the car online for $39,900. There's also a spirited conversation on Bring a Trailer about this automotive oddity.

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.
