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.

The tumultuous history of the diesel engine

Volkswagen, diesel's most enthusiastic patron, deceived everyone about the amount of emissions its cars were putting out. We have covered this latest massive automotive scandal in great detail, and there are surely more fascinating revelations to come. It turns out that this is just the latest episode in the epic story of the controversy and intrigue surrounding the diesel engine, and its inventor. This is the story of the tumultuous birth and interesting evolution of the compression-ignition engine at the center of the VW scandal. Napoleon III Got Rudolf Diesel Deported Rudolf Diesel was born in Paris in 1858. His Bavarian parents had settled in France where his father, Theodor, was a leather goods manufacturer. When the French Parliament declared war on Prussia, kicking off the Franco-Prussian war, the Diesels fled to London. When he was 12, Rudolf went to live with his aunt and uncle in the Bavarian university town of Augsburg. It was his parents' hometown, and importantly, it's where Rudolf began studying at the Royal County Trade School. His time in Augsburg, graduating at the top of his class from trade school that laid the groundwork for all that was to come. Diesel Nearly Blew Himself Up An early career in refrigeration saw Diesel running R&D in Berlin for Linde, a company started by refrigeration pioneer Carl Von Linde, one of Diesel's professors. His ambition to branch out beyond refrigeration, and his deep understanding of thermodynamics, led to efficiency experiments with steam engines. Diesel was trying to create an engine that didn't waste heat from the combustion process, therefore getting the most work out of the fuel. Instead, he was nearly killed when an experimental ammonia vapor steam engine exploded. Recovery took many months, and during some of that time, he was no doubt planning his next experimental engine, based on the theoretical Carnot cycle. His Engine Was An Attempt To Stick It To The Man Steam engines were expensive to run and wasteful. Diesel thought the efficiency of his design would be a way for the small business to compete with the dominant industrial giants. It was, and it did, but big business is equally passionate about chasing efficiency. Diesel engines quickly proliferated in industries both grand and cottage. Rudolf Didn't Really Invent The Diesel As We Know It Instead, he improved an existing one to a significant degree. The Diesel engine could be considered an evolution of the "hot-bulb" engine.

First Toyota unintended acceleration case headed for trial

Toyota is going to be back in the spotlight, as the first of its unintended acceleration lawsuits is headed for trial. This case covers a Los Angeles sushi shop owner, Noriko Uno. According to the what the family told The Detroit News, Uno only put about 10,000 miles on her 2006 Toyota Camry in four years. Uno was apparently afraid of high speeds, avoiding the freeway and taking a route home along LA's surface streets to avoid them.
On August 28, 2009, Uno's Camry suddenly accelerated to 100 miles per hour, eventually striking a telephone poll and a tree and killing her. The family contends that Uno attempted to step on the brakes and pull the emergency brake, neither of which brought her speed under control, while Toyota maintains that improperly installed floormats and driver error have been behind the majority of the 80 cases expected to be heard in court.
In Uno's case, The Detroit News is expecting the trial to focus on the lack of an override if the gas and brake pedals were pressed at the same time. Brake overrides were installed on Toyota's European fleet. The Uno family attorney will need to prove to the jury that it wasn't driver error that killed Noriko Uno.
