Top Gear drag races the BMW i8 and M4 to decide the future

The BMW M4 and i8 represent two every different expressions of the performance car. The M4 relies on its turbocharged six-cylinder combustion engine to spin the rear wheels. Conversely, the i8 packs a turbo three-cylinder and electric motors for its cutting-edge all-wheel drive system. Top Gear is the latest publication to put the pair together to find out which ethos is quicker. We saw Germany's Auto Bild hold a similar race last year, and the i8 scored a clear victory there. We don't want to spoil the winner of Top Gear's attempt, but we can tease that this sprint ends in a photo finish. Pick your favorite, and then watch the video to see which performance coupe takes the checkered flag. Related Video:

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.

Toyota Camry, Lexus RX to get aluminum parts

Ah, aluminum. The lightweight, strong material has long held a following within the premium ranks, but as Ford prepares to launch an aluminum F-150, the material is gaining acceptance among more mainstream automakers. Toyota is one such brand, with a new report indicating that the Japanese giant will add aluminum bits and bobs to some of its upcoming vehicles.
These won't be full, aluminum-intensive treatments like the F-150, however. Automotive News reports that an aluminum hood and liftgate will be coming to the 2016 Lexus RX, and following that, the Camry will get a bonnet built from Element 13 for model year 2018.
As AN points out, Toyota is no stranger to aluminum, using it in Japanese-built models like the Prius and Scion FR-S. The RX and Camry, though, will mark the first time the company's North American factories will use the material, and they'll do so on a significantly larger scale, owing to the higher volumes that the Camry and RX represent.
