Aston Martin will race the Valkyrie hypercar at Le Mans in 2021

Aston Martin will challenge for outright victory in the Le Mans 24 Hours race in 2021 with its Valkyrie hypercar, the British luxury sportscar maker announced on Friday after race organizers rewrote the rules. The governing FIA, who oversee the World Endurance Championship, and race organizers Automobile Club de L'Ouest, revealed earlier that hypercar derivatives would replace prototypes as the top category starting in the 2020-21 season. Aston Martin will field two works Valkyries, powered by V12 normally-aspirated engines, as part of a multi-year commitment to a championship currently dominated by Japanese manufacturer Toyota. The announcement comes 60 years after Aston Martin's sole overall triumph at Le Mans in 1959 with Britain's Roy Salvadori and American Carroll Shelby. Le Mans winner Toyota, meanwhile, has committed to staying in the WEC after 2020 subsequent to the hypercar rules. The Japanese manufacturer said in a statement before this weekend's race at Le Mans' Sarthe circuit that it would continue in 2021 with a hybrid-powered prototype based on the GR Super Sport road car. Track testing of the new car will begin next year. Defending champions Toyota will start on pole position on Saturday after sweeping the front row in qualifying for the third year in succession. "This new era of competition is a fantastic opportunity to demonstrate our credentials not only as a race team against some of the best in the business, but also as a sportscar manufacturer," said Toyota Gazoo president Shigeki Tomoyama. The 2021 Le Mans will also be the 100th anniversary of Aston's first entry at the Circuit de la Sarthe. "I think you'd say from the brand's point of view, there's a little bit of unfinished business to be done," Group Chief Executive Andy Palmer told Reuters. Top Formula One designer Adrian Newey, who has won championships with Williams, McLaren and Red Bull, helped create the Valkyrie. The limited edition road legal version costs in the region of 2.5 million pounds ($3.17 million). "We don't under-estimate the difficulty of an outright win at Le Mans and you never under-estimate the tenacity and resources of Toyota," said Palmer. "On the other hand, we're not coming just to make up the numbers. We're coming here to give it a bloody good shot." Palmer said the new regulations would significantly reduce the costs of competing, without giving details about the likely budget, and hoped commercial rivals McLaren and Ferrari would take up the challenge.

Lexus LFA prototype spied lapping the Nurburgring with new bodywork

The Lexus LFA was a real engineering tour de force. Sure, it was stuck in development hell for years, and the 4.8-liter V10's 552-horsepower output wasn't super impressive when it came out, but it integrated a ton of expertise Toyota gained from its F1 team in the early to mid 2000s. Unfortunately, it didn't sell well. Last year, we found there were a few new models sitting on dealer lots, five years after the 500-model run ended. Still, it looks like Toyota may not have given up on the idea of a race-derived flagship for Lexus, at least based on this prototype running around the Nurburgring this week. At first glance, the car pictured here looks like an LFA with the Nurburgring Package and some camouflage on the front and rear fenders. If you look closely, you can see that the fenders are significantly wider than on the standard LFA. Based on the license plate, this appears to be the same car with two different sets of wheels. Lexus may simply be swapping out worn tires, or they may be testing different wheel and tire combinations to fit the wider wheel wells. Anything beyond this is just speculation. There have been rumors of a new flagship Lexus sports car that sits atop the LC 500 and LC 500h. We saw the Toyota GR Super Sport Concept back in January, though that car looks nothing like what we see here. As much as we would love that sweet Yamaha co-developed V10 to carry over, we're not holding our breath. Some sort of hybrid powertrain is almost a certainty. Maybe Lexus and Toyota could pull some tech from its Le Mans-winning TS050 Hybrid race car. Related Video:

Asian automakers still reluctant to use more aluminum

There's a logical progression of technology in the auto industry. We've seen it with things like carbon-ceramic brakes, which use to be the sole domain of six-figure sports cars, where they often cost as much as an entry level Toyota Corolla. Now, you can get them on a BMW M3 (they're still pricey, at $8,150). Who knows, maybe in the next four a five years, they'll be available on something like a muscle car or hot hatchback. Aluminum has had a similar progression, although it's further along, moving from the realm of Audi and Jaguar luxury sedans to Ford's most important product, the F-150. With the stuff set to arrive in such a big way on the market, we should logically expect an all-aluminum Toyota Camry or Honda Accord soon, right? Um, wrong. Reuters has a great report on what's keeping Asian manufacturers away from aluminum, and it demonstrates yet another stark philosophical difference between automakers in the east and those in the west. Of course, there's a pricing argument at play. But it's more than just the cost of aluminum sheet (shown above) versus steel. Manufacturing an aluminum car requires extensive retooling of existing factories, not to mention new relationships with suppliers and other logistical and financial nightmares. Factor that in with what Reuters calls Asian automaker's preference towards "evolutionary upgrades," and the case for an all-aluminum Accord is a difficult one. Instead, manufacturers in the east are focusing on developing even stronger steel as a means of trimming fat, although analysts question how long that practice can continue. Jeff Wang, the automotive sales director for aluminum supplier Novelis, predicts that we'll see a bump in aluminum usage from Japanese and Korean brands in the next two to three years, and that it will be driven by an influx of aluminum-based vehicles from western automakers into China. Only time will tell if he's proven right. News Source: ReutersImage Credit: Sean Gallup / Getty Images Plants/Manufacturing Honda Hyundai Mazda Nissan Toyota Technology aluminum
