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. See the first video below for more information, or check out the article at Carscoops.

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.

      The Duke Engine reminds me of the revolutionary MYT engine devoloped by inventor Raphial Morgado of Angel Labs - have been loosely following the engine for a number of years - sadly commercialisation is still to be achieved due to funding to my knowledge. http://www.angellabsllc.com

      I'm sure the MB E300 left With a full tank of DIESEL, rather than gas. If they had gas, they wouldn't have made it one block, let alone as far as they did. As I'm sure you know, diesel and gas are both fuels, but gas isn't diesel and diesel isn't gas.

      Smart has done nothing but lose money. Tesla built a roadster and became a 20bn$ company. In her infinite wisdom she concluded a roadster has no potential. It has great potential if you make it interesting.. if you do it right. call me. the duke engine looks cool but is meritless.

      An interesting element of the duke engine is that it is in a way a crossbreed of conventional piston and wankel rotary engine teschnologies in that it takes advantage of the rotary motion that enables it to utilize intake and exhaust ports and fewer spark plugs. As a result, the issues of port and top cylinder plate sealing may also come into play in this design.

        I first learned about this technology five years ago at a trade show. It looks like the've made a lot of progress since then but I agree, sealing especially during the combustion cycle looks to be problematic. Without adequate sealing, it will be down on power and high on emissions. The nice thing about poppet valves is that during the combustion stroke they are slammed shut by the combustion force, hard to beat for sealing purposes. It does look very compact, I wish them luck!

      That axial engine is cool. Much like the Wankel, however, it looks like a nightmare with oil seals.
