Recharge Wrap-Up: No new Smart Roadster, Africa to UK on one tank, Duke’s efficient axial engine [w/videos]

Smart will not make another generation of the Roadster, but a Smart SUV might be in the cards. According to Smart’s CEO, Annette Winkler, “The Roadster isn’t a profitable business case. Everybody is keen on the car, but nobody wants to pay the bill.” What Car? states that Smart is likely planning a baby SUV to take on the Nissan Juke and its ilk. But for the immediate future, Winkler says Smart “must focus on how we can maximize potential of the Fortwo and Forfour. That is strategy number one.” Read more over at What Car?.

A Mercedes-Benz E300 Bluetec Hybrid made the 1,223-mile trek from Africa to the UK on just one tank of fuel. Driven by Andrew Frankel of Autocar, the diesel hybrid left Tangier, Morocco with a full tank of gas (using the optional 80-liter fuel tank), and arrived in Goodwood with the car indicating 100 miles of range left. Frankel and his co-driver averaged 61.2 miles per gallon (73.6 mpg UK) on the intercontinental journey through four countries, despite elevation changes and a traffic jam.

Duke Engines promises simplicity and efficiency from the axial engine it’s developing. Rather than lining up the cylinders, this engine arranges them in a circle, which allows Duke to avoid unnecessary weight. The five-cylinder, four-stroke motor manages the same amount of powerstrokes per revolution as a standard six-cylinder mill, but weighs 30 percent less. It also has much fewer parts, says Duke. Its high compression ratios mean more power with less fuel, which adds up to more efficiency and fewer emissions. The second of the two videos below, which we first found over at Sploid, explains Duke’s axial engine.
