The new Aston Valkyrie AMR Pro, which takes its name from the Prodrive-run Aston Martin Racing squad that competes in the World Endurance Championship, is more powerful and lighter than the road auto, as well as incorporating revised aerodynamics.
Red Bull Technology's Chief Technical Officer, Adrian Newey, said: "While it is endowed with extraordinary performance, it has always been vitally important to me that the Valkyrie functions well as a true road vehicle, and that naturally comes with some constraints". Developed in parallel with the road vehicle, the Valkyrie AMR Pro is "freed from the constraints and considerations of road use", according to the release. Flat out, the top speed is estimated to be around 400km/h, while the cornering force potential is in excess of 3.3g, with braking force of over 3.5g - this is serious rollercoaster territory. The electric part of the hybrid system will remain unchanged, but Aston says that it has recalibrated the engine and made modifications to the emissions control systems (at least auto makers are being honest about it these days) to boost power and torque. All surfaces have been enhanced, with larger front and rear wings, and updated active areas that move about to provide the ultimate in aerodynamic efficiency.
Aston hasn't released any Valkyrie AMR Pro specs, but we've heard the Valkyrie street vehicle will produce around 1130 hp and weigh just under 2300 lbs. We can't wait to see the real thing.More news: Karnataka: Private doctors call off strike, protests to continue in Belagavi

Details of the extra power and torque from the hypercar's naturally-aspirated 6.5-litre Cosworth V12 have not been revealed, but have been achieved by engine recalibration and a modification of the road car's emissions control systems. Further savings come from the windscreen and side windows being made from a polycarbonate material. They sit outside Formula One-inspired race-spec carbon brakes. The AMR Pro version rides on smaller diameter wheels than the road vehicle (18 inches front and rear) to allow for the fitment of Michelin racing tires.
New suspension uprights and carbonfibre wishbones save more mass, and the normal seat has been swapped for an ultra-lightweight pair of moulded race seats. Those lucky enough to take delivery will have access to Red Bull's driver training facilities, including time in the simulator and professional on-track tuition, plus programmes to improve physical fitness.
Only 25 examples of the AMR Pro Valkyrie will be built, but don't think you can get your hands on one - they've all been sold. The vehicle itself will have its own dedicated track events for owners to show up and drive.
