Porsche 911 GT3 R Hybrid (2011) first official pictures

Porsche has released details of its updated 911 GT3 R Hybrid – the 2010 original nearly won last year's Nurburgring 24hr race before (ironically) it retired with petrol engine failure.  The 2011 Porsche 911 GT3 R Hybrid – the lowdown Before this report disappears in a chorus of ‘it looks the same as last year’s one’, let's outline where Porsche’s engineers have been busy. At the unfashionable end of the car remains a 4.0-litre flat-six engine producing approximately 470bhp. Up front are twin electric motors, now producing 75kW of power each (up from 60kW) and combined these give the GT3 R Hybrid a 197bhp electric boost, which can be programmed to activate automatically via the throttle pedal, or manually selected during overtaking. F1-derived hybrid tech for the 911 GT3 R Hybrid Power for the two electric motors doesn't come from batteries, but flywheel accumulator technology from Williams Hybrid Power, an offshoot of the Williams Formula 1 team. The flywheel, encased in a carbonfibre safety cell in the space where the passenger seat would be, spins at up to 40,000rpm and acts as a mechanical energy store for the electric motors. Regenerative braking feeds energy back into the flywheel system – no surprises there, as the technology is derived from Williams' exeprience with Kinetic Energy Recovery Systems (KERS) in F1.

Jaguar Land Rover Special Operations division launches

Cars like the Jaguar F-Type Project 7 (pictured) will come from JLR’s Special Operations If the creation of the Jaguar Land Rover Special Operations division to create bespoke, heritage, ultra luxury and high performance Jaguar, Land Rover and Range Rover cars doesn’t shout how positive JLR are about the future, nothing will. Jaguar call it “meeting the increasing expectations of today’s most discerning and enthusiastic car customers“, but what they really mean is that JLR have now got so much back on their game with cars like the new Jaguar F-Type, new Range Rover and new Range Rover Sport that they now have buyers with deep enough pockets to pay for just about anything, so that’s what JLR are going to do with the Special Operations division; give them anything they want – at a price That will mean car like the Jaguar Project 7 F-Type we saw at Goodwood last year being possible, ultra-luxury versions of the Range Rover and even the creation of heritage cars like the new Lightweight E-Types could become a regular occurrence. With a team of engineers and and designers led by Paul Newsome, recently recruited from Williams Advance Engineering, the plan is to create halo vehicles for both the Jaguar and Land Rover brands, and a team of 150 at a new Technical Centre near Gaydon will have a customer commissioning suite for bespoke and premium personalisation.

Fuel Injection Pioneer Stuart Hilborn 1917-2013

Stuart Hilborn, the dry lakes hot rodder whose racing fuel injection systems powered almost the entire field at Indianapolis some years, died Monday at the age of 96. Hilborn first went to the dry lakes in 1938 and was amazed to see engine builders and racers who hadn't gone to college producing twice the horsepower of a stock setup. “I was very impressed that they had doubled the horsepower of the cars as they came out of Detroit with virtually no money at all, just work,” Hilborn told the American Hot Rod Foundation.
