Brabus boosts big Benz plug-in hybrid

With vehicles like the BMW i8 and Porsche 918 Spyder, the Germans have demonstrated as well as anyone that "performance" and "hybrid" can go in the same sentence. And now Brabus is plugging in to the performance hybrid station as well. Though nowhere near as extreme as the aforementioned PHEV sports cars, the Brabus PowerXtra B50 Hybrid performance kit kicks the Mercedes S550 Plug-In Hybrid up a notch. The electric side of the powertrain remains untouched, but the internal combustion engine has been boosted by 51 horsepower and 52 pound-feet of torque. That gives the 3.0-liter turbocharged V6 a total of 385 hp and 405 lb-ft, which is nothing to cough at – but with the electric boost kicking in, the vehicle now packs a combined output of 493 hp and 656 lb-ft. That slots its twist figure in between that of the S600 and S63 AMG. As a result, the big Brabus hybrid will now reach 62 miles per hour from a standstill in just 4.9 seconds (down from 5.2) – almost as quick as the 12-cylinder model but with half the pistons – though the top speed remains pegged at 155 mph. Naturally, Brabus didn't stop there, giving the sedan a new exhaust, aero kit, rolling stock and interior, all catered to the customer's specifications. BRABUS PowerXtra B50 Hybrid with 368 kW / 500 hp (493 bhp) and 890 Nm of torque The eco-friendly performance upgrade for the new Mercedes S 500 PLUG-IN HYBRID For more than 35 years, BRABUS has been the synonym for powerful high-performance automobiles and exclusive refinement at the highest level of perfection. One philosophy has always been paramount in all these years: combining top performance with exemplary eco-friendliness, immaculate durability and perfect everyday practicality. With the new BRABUS PowerXtra B50 Hybrid performance kit for the new Mercedes S 500 PLUG-IN HYBRID, the engine specialists of the world's largest independent tuner once more demonstrate their unrivalled know-how. The power increase of the V6 engine by 38 kW / 52 hp (51 bhp) and the boost in torque by 70 Nm (52 lb-ft) bumps the system output of the hybrid sedan to 368 kW / 500 hp (493 bhp) and system torque to 890 Nm (656 lb-ft). As a result, the luxury liner sprints from rest to 100 km/h (62 mph) in just 4.9 seconds, and impresses in daily driving with even further enhanced superiority. Due to the hybrid system, the top speed remains electronically limited to 250 km/h (155 mph).

Mercedes-AMG planning more hardcore A45 hot hatch

The launch of the A45 AMG marked Mercedes-Benz's first real assault on the premium hot hatch segment. And with 355 horsepower from a 2.0-liter turbo four, it is indeed hot. But the latest word has it that Mercedes-AMG is planning an even hotter version. Speaking with Auto Express at the LA Auto Show last week, AMG boss Tobias Moers indicated that his department was toying with the idea of a more hardcore version of the A45. In what Moers referred to as a "street fighter," the A45's engine would be tuned to produce even more power, the cabin stripped out and the rolling stock, brakes and aero upgraded for more serious performance. Think of it, then, as something of a Black Series approach, only it's not expected to carry that name, which has historically been reserved specifically for two-door models. Given AMG's current list of priorities and limited manpower, though, Moers suggests it will be several years – likely towards the end of the model's life cycle – before it may prepare such a model, following a similar formula to the Mini JCW GP and Renaultsport Megane R26.R. Here's hoping an American version based on the CLA could also be in the cards.

Gordon Murray, F1-driven production and .. the Pontiac Fiero

Gordon Murray's design and engineering chops are unquestionable. But does his carmaking approach owe something to the short-lived Pontiac Fiero, a scrappy little car program that emerged from GM against serious resistance? Murray had a Formula One career that ran from 1969 to 1991, with stints at Brabham ('69 to '86) and McLaren ('87-'91), that resulted in several shelves' worth of trophies for the cars he was instrumental in designing. He moved on to McLaren Cars, the consumer side of things, where, during his tenure from 1991 to 2004, he helped design the McLaren F1 and the Mercedes-Benz SLR McLaren, two cars that took learnings from his two decades in Formula One. What do all of these cars have in common? Three things: They are light. They were built in limited numbers. And they were (and are) exceedingly expensive—when the McLaren F1 debuted in 1994, it stickered at $815,000. Murray went on to establish Gordon Murray Design in 2007. GMD has created some interesting concept vehicles, such as the diminutive T.25 city car (94.5 inches long, 51.1 inches wide and 55.1 inches high), and the OX, a lightweight truck for the developing world that packs like an IKEA shelf and is working toward realization through a worthy crowdfunding campaign established by the Global Vehicle Trust. Now he has created a vehicle manufacturing company, Gordon Murray Automotive, that will use manufacturing methods that he developed under the moniker "iStream." Unlike a unibody, there are the "iFrame," a cage-like construction made with metallic components, and the "iPanels," which are composite. The panels aren't simply a decorative skin; they actually provide structure to the vehicle. Presumably this has something of the F1 monocoque about it. Going back to the three elements, (1) this arrangement results in a vehicle that can be comparatively light; (2) Murray has indicated that his manufacturing company will be doing limited-run production; and (3) to launch Gordon Murray Automotive they are going to be building a flagship model, about which Murray said, "With our first new car, we will demonstrate a return to the design and engineering principles that have made the McLaren F1 such an icon." Which seems to imply that it will be on the pricey side. According to the company's verbiage, "iStream forges an entirely new production method that defies conventionality with its Formula One-derived construction and materials technologies." It also sounds a whole lot like ...
