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.

Chinese-made Cadillac CT6 Plug-In starts US sales

General Motors has started US sales of the Cadillac CT6 Plug-In after taking its first domestic deliveries of the China-produced sedan last month. The model is GM's first new plug-in hybrid in the US since the automaker discontinued sales of the ELR extended-range plug-in last year. The arrival and sales, first reported by InsideEVs, were confirmed by Cadillac spokesman Andrew Lipman. Not surprisingly, the sedan isn't cheap, as the CT6 Plug-In is priced at $75,095, or almost $12,000 more than the gas-powered variant, though that figure doesn't include federal and state tax credits for electric vehicles. For that tab, buyers get a 335-horsepower luxury car that can go 31 miles on electricity alone, and 0-60 miles per hour in a little over 5 seconds. The model gives GM three plug-in vehicles to sell to the American public, or the same number US competitor Ford offers. InsideEVs estimates that about 100 of the sedans have been delivered to US dealers, so the car remains a relatively low-volume affair. By comparison, GM's Chevrolet division has sold 5,563 Volt extended-range plug-ins and 3,092 Bolt electric vehicles through March. Cadillac sold 534 units of the ELR in 2016 after moving 1,024 the previous year. GM opted to produce the plug-in hybrid in China because of that country's receptiveness to new models that feature alternative and environmentally friendlier powertrains. Additionally, such production shortens the distance to the CT6's battery maker LG Chem, which is producing the car's battery packs in South Korea. On that note, GM has previously estimated that the Cadillac CT6 Plug-In will move more units in China than in the US. Related Video:

Super Cruise will make 2018 Cadillac CT6 semi-autonomous

General Motors has been working on its semi-autonomous driving system for years. Called Super Cruise, it had initially been slated for a fall 2016 debut. Of course, something as critical to safety as a self-driving system should ideally have the bugs worked out before putting it in the hands of customers, and the launch date had to be pushed back. It appears that Super Cruise is road-ready now, as Cadillac has announced the system will be available in the 2018 CT6 sedan when it goes on sale this fall. Super Cruise offers hands-free driving on the highway, taking control of steering and speed under the supervision of the driver. An attention detection system – a camera and infrared lights that track head position – ensures that the driver is paying attention and is available to take over driving responsibilities. If needed, Super Cruise will initiate a series of nags, including a flashing light bar on the steering wheel, to regain the driver's attention. If the driver is unresponsive, the system can bring the car to a safe stop and use OnStar to call first responders. The system employs a suite of sensors, cameras, and GPS, as well as precision lidar-scanned map database, to place the car where it needs to be on the road and in the center of its lane. It only works if the sensors detect appropriate road conditions, and is limited to the more predictable terrain of divided highways with on- and off-ramps. Yes, it's limited, but safety is paramount, and drivers who spend a lot of time on the highway will appreciate the convenience nonetheless. Related Video:
