Concept of the Day: Mercedes-Benz Vision G-Code

merc vision g-codeMercedes-Benz has revealed a high-riding 2+2 hatchback concept called Vision G-Code, featuring a hydrogen-electric powertrain. Developed with M-B’s advanced design studio in Beijing and unveiled to mark the opening of a new R&D facility in the city, it’s a foretaste of M-B’s attempts to attract young buyers in the Asian market, reports Autocar. It’s shorter, wider and taller than the GLA; and that powertrain – developed from that of the upcoming B-Class F-Cell  (2017) – gives three modes, all-electric (RWD) and hydrogen-electric ‘eco’ and ‘Hybrid Sport’ (with engine driving the front axle as well). The hydrogen-fuelled engine is turbocharged, and works with a dual-clutch gearbox via a “digital propshaft”; the G-Code further has plug-in capability to enhance its all-electric range, plus ‘multi-voltaic’ solar- and wind-energy generative paint and hydraulic suspension with energy capture; the air con system pumps out air with the oxygen produced in hydrogen synthesis. There’s also smartphone-operated ignition and driver settings – and a pair of electric scooters stored under-floor in the boot for last-mile city mobility. More detail from Daimler here. (And some comment on the B-Class E-Drive here).

  • Fisker Automotive – now under ownership of China’s Wanxiang Auto – is preparing to relaunch the Karma PHEV and related (as-yet stillborn) Atlantic, with hybrid powertrain control software supplied by Quantum. A deal has been signed; press release posted here.
  • Renault has signed a formal partnership with La Poste to test and develop new vehicles in addition to the current EVs they are running, including differently-sized parcel delivery solutions, and technologies; more here. This coincides with the delivery of the 5000th Kangoo ZE.
  • And a Renault-led project: a two-cylinder, two-stroke 730cc compression-ignition diesel engine with common-rail injection, 50-60% lighter than an equivalent four-stroke, and suitable for Twingo-type vehicles. More on the POWERFUL research at Green Car Congress and here.
  • The fastest EV 0-60mph is now ‘grimsel’, a prototype built by students at ETH Zurich and Lucerne University of Applied Sciences and Arts; this Formula Student competitor achieved a 1.785sec time on an airfield at Dubendorf. More here.
  • Coventry University spin-off Microcab is to show a new commercial/van version of its H2EV microcar at the Advanced Engineering UK show in Birmingham next week. More here.
