Infiniti Q50 Red Sport 400 priced at $48,855, AWD at $50,855

Infiniti's most powerful production model, the new Q50 Red Sport 400, now has a starting price. You'll need at least $48,855 for the rear-drive model or $50,855 for all-wheel drive. (Both figures include the $905 destination charge.) A fully loaded, rear-drive Q50 RS400 with Direct Adaptive Steering, navigation, adaptive cruise control, a heated steering wheel, and Infiniti's entire alphabet soup of safety equipment, tops out at $57,045. (Again, add $2,000 for AWD). When it comes to rear-drive competition, the closest base price to the Q50 is the 320-hp BMW 340i. This German undercuts the Infiniti by two grand, $46,795 to $48,855. But the BMW outprices the Q50 as soon as you start selecting options. A 340i with similar equipment to a loaded Q50 Red Sport 400 costs just under $60,000. All-wheel-drive German competitors also lose out in the price war. Like with the rear-drive models, the BMW 340i xDrive undercuts the Q50 RS400 by around $2,000. Add the options, and the Infiniti becomes a better value. The other two big German rivals, the Audi S4 and Mercedes-Benz C450 AMG start at a higher price and only get more expensive. Technically the S4 starts cheaper than the Q50, but only with the standard manual transmission. Selecting the S-Tronic dual-clutch model kicks the price from $50,125 to $51,125, and going for the top-end Prestige trim will bump potential Audi owners up to $57,025. Throw on must-have S4 options, including adaptive cruise control, adaptive dampers, and a sport differential and you'll be shell out $64,425 for the Audi. The Mercedes-Benz C450 AMG is the priciest choice in this group, starting at $51,725, or roughly $900 more than a base Q50 RS400 with AWD. Options, again, are the downfall here. Building a C450 to match a loaded Infiniti will drive the Mercedes' price up to $64,315. While it occupies something of a weird space relative to these vehicles, it's also worth mentioning the Cadillac CTS VSport. It's the only car in this impromptu pricing comparo that can outgun the Q50, with its 3.6-liter, twin-turbo V6 good for 420 hp and 430 lb-ft of torque. It also starts at $60,950, although that includes plenty of standard equipment. All this means that the Q50 Red Sport 400 represents a relative value. It packs more power than the Germans – 80 more than the 340i, 67 more than the S4, and 38 more than the C450 – and a more comprehensive list of options, too.

Mercedes-Benz F 015 Luxury in Motion has an absurd name, remarkable vision

We often hear about cars that don't look good in pictures. "You need to see it in person," people say. Well, the Mercedes-Benz F 015 Luxury in Motion, which the company brought to Detroit after debuting it at CES, is just such a vehicle. Besides having a very silly name and looking, according to one Autoblog editor, like a suppository, this is a genuinely striking piece of design when viewed in the metal. The shape is aerodynamic in the extreme, but still features subtle details and styling cues. Whether that be the small dorsal ridge on the roof, the simply huge wheels and the Cylon-like, wraparound taillights, despite a fairly uniform shape, there's still a lot to see on the F 015. That's doubly true in the cabin, which is typically luxurious, while also doubling as a rolling lounge withs eating for four. Accessible via barn doors that open up to 90 degrees, the F 015's cabin features fine woods and leathers, as well as seats that swivel around to face each other. Screens abound (there are six in total), and gesture-and-touch-based controls are the order of the day, producing what Mercedes calls a "digital arena." As an autonomous vehicle, MB doesn't offer a lot of technical information on propulsion or guidance systems, simply saying that the pod-like concept could accommodate an electric motor and fuel cell. Take a look at our gallery of live images Mercedes' sci-fi vision, and if there's an auto show coming to your neck of the woods, get out and see this strange and impressive car.
