BMW E9 3.0L CSL Batmobile is an awesome retro racer

When BMW released pictures of its 3.0 CSL Hommage earlier this year and then brought a period-livery racing example to Pebble Beach, this is the car it was looking at. The BMW E9 New Six CS came before BMW Motorsport and BMW M cars existed, and well before the tagline "The ultimate driving machine," but it paved the way for all of them. Built as a road-going coupe from 1968 to 1975, 1,265 units out of a total production run of 30,546 units were homologated for the European Touring Car Championship. Fitted with the final specification aero package in 1973 and powered by a 3.003-liter inline six-cylinder with a base rating of 200 horsepower, it proved such an able racer that it won the overall ETCC trophy six times - four of those after its road car donor had ceased production, and a bunch of other races like a class win at Le Mans. Clean samples go for huge money. That aero kit earned it the nickname "Batmobile," and Car Throttle drove a left-hand-drive version in the UK (BMW did build 500 right-hand-drive models, though). This is less a car review and more a dream drive, the host letting us know right off that the 3.0 CSL is the one car he's wanted to drive more than any other. He also finds that the Coupe Sport Leicht had a stop/start system... of the temperamental kind. Check it out in the video above. Related Video:

Protonic Red BMW i8 will bow in Geneva

BMW will unveil special edition versions of the i8 at the Geneva Motor Show, but we hope the rest of the company's offerings are more exciting than its first one – the new Protonic Red Edition. BMW bathes this limited edition i8 in the eponymous red and paints some the trim Frozen Grey metallic. The company finishes off the exterior improvements with 20-inch W-spoke wheels that it decorates Orbit Grey metallic with Aluminum matte hubs. The interior upgrades amount to red double-stitching around the cabin and the addition of some carbon fiber and ceramic trim. There are no mechanical changes. It's hard to get too excited about special paint and trim, but if you are in the market for a more colorful i8, then the Protonic Red Edition seems like a good opportunity. Production begins in Leipzig in July. Related Video: Comfortably exceeding expectations: BMW i8 is the world's highest-selling hybrid sports car. Exclusive BMW i8 special editions.

Recharge Wrap-up: Houston's bus revival, autonomous trucks on the Autobahn

A documentary shows how Houston, Texas significantly improved its outdated bus system. Called High Frequency: Why Houston is Back on the Bus, the short film describes how the city reimagined its bus system to become more efficient, more useful and more popular. Despite some opposition, the change has proven to be effective, with bus ridership up eight percent in three months, and light rail ridership up due to complementary bus routes. See the video above, and read more at CityLab. Automakers sent autonomous semi trucks on the German Autobahn as part of the European Truck Platooning Challenge of 2016. Mercedes-Benz, Volvo and Scania, among other groups, sent platoons of trucks between Stuttgart, Germany, and Rotterdam, Holland. In Mercedes's platoon of three trucks, the lead truck was fitted with lasers and other sensors to guide the convoy down the road. The two following trucks relied on vehicle-to-vehicle communication to trail 50 feet behind the lead, making room for cars to come between them and closing the gaps when able. The close following distance provides fuel economy gains of up to 10 percent in the rearward trucks on account of the reduction in drag. Read more at Hybrid Cars.
