Mazda: Rx-7 Touring on 2040-cars

This is what a 1,200-hp twin-turbo 4-rotor looks like in a Miata

We've seen the diminutive Mazda MX-5 Miata swallow plenty of big engines, but New Zealand drifting ace "Mad Mike" Whiddett is roaring into where-no-man-has-gone-before territory. Wanting to replace his 515-horsepower "MADBUL" RX-7 and its twin-turbocharged, three-rotor 20B engine, his new ride is an NC-series Miata with four rotors and twin Garrett turbochargers courtesy of Pulse Performance Race Engineering. It is called "RADBUL," and expected power at standard boost is 1,200 hp, but the builders at Pulse Performance think it will get up to 1,500 hp at full boost. And yes, that exhaust exits through the hood. Four-rotor engines are actually popular - builds are detailed on forums like this one from 2007 and this one from 2008, this UK company or this Canadian company will sell you one complete - but they're usually being prepped for an RX-7. Mad Mike's choice of a Miata for this enterprise makes this about as extreme as you can get, short of throwing it into a Mazda R360. You can watch Mad Mike tell the story of the build in the video, and check out the first and second installments about the build on the Red Bull site.

Toyota, Honda, Mazda and Nissan recall 3.4 million vehicles for faulty airbags

Most vehicle recalls that take place these days are a result of some problem that happens during the manufacturing process by the automaker, but as we see here, parts suppliers can also factor in to problematic safety issues. Automotive News is reporting that a total of 3.4 million vehicles produced by Japanese automakers between 2000 and 2004 are being recalled globally due to faulty airbags produced by an outside supplier, Takata Corp.
According to the report, vehicles from Toyota, Honda, Nissan and Mazda are being recalled because of passenger front airbags that do not inflate properly. Globally, Toyota is said to be recalling around 1.73 million cars including 510,000 in the US composed of Toyota Corolla, Matrix, Sequoia and Tundra as well as the Lexus SC430 for the 2001 through 2003 model years; this is the second time this year the 2003 Corolla and Matrix have been recalled for an airbag problem. Honda is recalling 1.14 million models, Nissan another 480,000 and Mazda 45,463. The article says that Takata supplied faulty airbags to non-Japanese automakers, but it did not specify which ones.
Honda and Toyota have released information on their own websites about the recall, while Nissan and Mazda have not yet commented. Read official press releases from Honda and Toyota, below, and look for updates as we have word from the others.

Weekly Recap: Tesla loses money, still dominates the news

Some people get an inordinate amount of attention. In politics, it's Donald Trump. In football, it's Jim Harbaugh. And in the auto world, it's Elon Musk and his always-fascinating electric car company, Tesla Motors. General Motors is spending $877 million to upgrade a factory. So what! US auto sales are up. Who cares? Tesla has a metal snake that will recharge your car! So was the week in Tesla – er, the industry. Snarkiness aside, Tesla did dominate the news cycle, led by the announcement the company lost $184 million in the second quarter. Tesla also said it expects to deliver between 50,000 and 55,000 vehicles this year, and is preparing for a full launch of the Model X crossover in September. Musk also made news during the earnings call by simply not answering a question about ride sharing, leading to speculation Tesla could be considering its own operation. While the financials were the arguably the most important company news, reports of a Model S cyber hacking were more compelling fodder for Tesla followers. Researchers were able to attack the sedan and bring it to a stop, though they required access to the car first. Tesla says it already has deployed a remedy for the situation. On a lighter note, Tesla published a video of its metal charger prototype that autonomously uncoils like a snake to power up the company's vehicles, provoking plenty of humorous comments and comparisons. Watch it and decide for yourself. While some of this might seem trivial, much of Tesla's recent attention has been warranted. It's the first startup US automaker in decades to launch from nothing and actually gain traction in the market. Sure, Musk is a lightning rod and Tesla always seems to be in the spotlight. But amid all of the publicity, it easy to lose sight of the new reality: Tesla is a force.
