SRT has resumed production of the Viper at Chrysler’s Conner Avenue factory in Detroit, Michigan.

Last April, the automaker was forced to temporarily stop Viper production and lay off 91 employees because dealers in the United States and in Canada had a total of 756 unsold Vipers in their inventory. At the time, company executives downplayed the situation and explained buyers were waiting until the end of a particularly harsh winter to go car shopping.

SRT reports it has sold a total of 354 Vipers in the United States and 70 additional examples in Canada over the first six months of the year. The arrival of limited-edition models like the Time Attack (pictured) and the Anodized Carbon Editions has helped move cars off of dealer lots.

Infiniti Red Bull Racing’s top Formula One engineer, Adrian Newey, is being brought further into the Infiniti fold. Though what new projects he might work his magic on have yet to be delineated, something outlandish is to be expected.

Nissan Executive VP Andy Palmer told Top Gear that “Adrian is itching to do something new,” and when asked whether that something new could mean an Infiniti supercar, merely answered, “Watch this space.”

While noncommittal to say the least, the Infiniti-Red Bull deal is one of Palmer’s babies, a deal that saw Nissan’s luxury marque take over title sponsorship of the Red Bull F1 team and rebrand the engines of corporate bedmate Renault. That hasn’t stopped wildfire rumors of an Infiniti supercar borne from its F1 efforts from spreading across the internet.

Of late, Newey has expressed dissatisfaction with F1, saying regulations are threatening to make the series a “glorified GP2″ consisting of identical cars with different sponsors. Newey also recently turned down an $34 million offer to rescue Ferrari’s F1 team from its current state.

Newey is an expert aerodynamicist who was responsible for designing the Red Bull X1 and virtual Red Bull X2014 for the Gran Turismo video game franchise. In the real world, Newey was responsible for the F1 cars that carried Sebastien Vettel to his four-year winning streak from 2010-13.

BMW will not be building an M4 Gran Coupe. That’s the word straight from M brand sales chief Jörg Bartels’ mouth.

Those yearning for a bustle butt sedan with a 430hp twin-turbo straight-six may be disappointed, but as Bartels told Australia’s Cars Guide, it’s just a matter of logistics.

The current 3-Series sedan — and thus the M3 — are built at BMW’s Regensburg factory while the 4-Series coupe and M4 are built in Munich. The 4-Series Gran Coupe is built in Dingolfing, and it would not make financial sense for BMW to make the necessary changes to a third plant in order to birth more Ms.

Bartels did say that the idea was considered, but it would require too much effort to modify the lines to accommodate the added structural and drivetrain variations on those lines, and BMW did not see the Gran Coupe selling in enough numbers to make it worthwhile. Thus, the idea was scrapped, along with plans for the M version of a 3-Series Gran Turismo.

So it appears that are at least some limits to BMW’s ever-expanding count of body style and drivetrain combos. Still, the current generation of M branded cars will see one more variant, the M4 convertible planned for 2015.

An ambitious California-based start-up named Cruise Automation has announced it is in the final stages of developing an autonomous highway driving system called RP-1.

Cruise’s RP-1 is far less advanced than the self-driving technology that Google has spent years developing. Relying on the company’s own maps, the system is centered around a roof-mounted sensor pod that uses lasers, cameras and sensors to scope out the road ahead and send data to a computer mounted in the trunk. The computer evaluates the data and automatically adjusts the steering, the throttle and the brakes in order to keep the car in its lane.

The RP-1 has its fair share of limitations. It can’t change lanes, it can’t maneuver around traffic and it doesn’t work in the rain, in dense fog or in the dark.

“Car companies tend to be a lot more cautious in rolling out new technologies because potential problems that can lead to recalls puts their brand at substantial risk,” explained Vogt. “Being a start-up, we operate much leaner and can move faster because we can take a more straightforward approach in protecting ourselves against any liability.”

France’s Citroën has fully unveiled the DS 6WR crossover that it previewed at last April’s Beijing Motor Show. Designed to boost the firm’s presence in China, the DS 6WR is boldly aimed at the Audi Q3 and the BMW X1.

The DS 6WR wears an upscale design that borrows a noticeable amount of design cues from the Wild Rubis concept that was presented at last year’s edition of the Shanghai Motor Show. It wears a muscular front end with a bulged hood, sharp LED headlights and the firm’s trademarked “DS Wings” radiator grille. The back end features horizontal tail lamps inspired by the DS5 hatchback.

Newly-published pictures reveal the DS 6WR packs an opulent cabin with acres of leather upholstery, LED ambient lighting and imitation brushed aluminum trim on the center console, the dashboard and the four-spoke steering wheel. A digital instrument cluster that includes a configurable screen comes standard, and most models are equipped with a small touch screen on the center stack that runs the latest generation of Citroën’s infotainment system.

Power for the crossover comes from a selection of gasoline-burning four-cylinder engines lifted from the brand’s parts bin including a 1.6-liter unit that generates 200 horsepower. The crossover is only offered with front-wheel drive but Citroën’s Grip Control technology helps improve traction in challenging driving conditions.

The DS 6WR will be built in Shenzhen, China, and sold exclusively on the local market where DS-badged cars are distributed in standalone showrooms. Pricing information will be published closer to its on-sale date.
