What happens when you take an engineer sliding in a BMW i8

The BMW i8 is a pretty impressive car, and a highly visible one at that. It's a great brand ambassador, but not just for BMW. It's really no surprise that Formula E chose it as the safety car from the electric racing series. And, for its duties at tracks around the word, the i8 safety car got some slick upgrades, including wireless charging capabilities courtesy of Qualcomm. It's not your regular, cut-and-dry technology presentation. In the video below, Qualcomm engineers explain a little bit about what they do to enhance electric vehicles. But it's not your regular, cut-and-dry technology presentation. The engineers are forced to answer questions about Qualcomm's technology while riding along in the BMW i8 Qualcomm Safety Car driven by none other than Formula E driver Nelson Piquet, Jr. Sure, riding shotgun for hot laps at Donnington Park in an i8 sounds like a lot of fun, but these guys have a job to do, and Mr. Piquet isn't making it easy for them. The Qualcomm guys talk about taking technology and beefing it up for automotive use, explain the benefits of wireless charging and discuss some other stuff that's hard to pay attention to while watching the i8 get totally sideways in a smoky powerslide. See for yourself in the video below. If you miss something, don't worry; Qualcomm provides more explanation about its automotive technologies at its website, including safety, communication and, of course, inductive charging.

BMW replaces tri-turbo diesel with a quad turbo

Quad turbos have until now been the stuff of Bugattis. BMW is introducing a quad turbo diesel for the 7 Series, with nearly one hundred horsepower per turbo. It's all about making the six-cylinder 3.0-liter turbodiesel all as enticing a proposition as possible, and it faces strong competition from Audi's new twin-turbo V8 diesel available in the SQ7 TDI. The earlier, N57S engine (pictured above) utilized a triple-turbo setup good for 381 horsepower and 546 lb-ft. The new B57 version, confirmed by BMW at the 37th International Vienna Motor Symposium, adds yet another turbo for 394 hp and 561 lb-ft, and that massive torque is available from 2,000 to 3,000 rpm. It means the 7 Series gets from 0-60 mph in a snappy 4.5 seconds. The engine could produce even more torque, but 561 lb-ft is all the ZF 8HP 8-speed automatic transmission can handle. The N57S engine's dual-stage turbocharging setup consisted of one low-pressure turbocharger to take care of low-end torque, and two high-pressure turbos for the higher rev range. In the new B57 engine, the big turbo is now replaced with two smaller units on a common exhaust, to benefit from lower costs and smaller unit weight. In addition to the gains in power and torque, fuel economy has reportedly been improved by 5 percent. There are no reports yet whether the B57 TOP quad-turbo will make it to the US market, but customers in the European high end diesel saloon market will probably be very excited. Initially it will be available in the 750d xDrive version, and other top-end models like the 5 Series and the X5 will follow later on.

In case you forgot, the Dubai Police supercar fleet is the coolest

Ever wonder why the Dubai Police have a fleet of vehicles worth millions and millions and millions of dollars? Why it has a Bugatti Veyron and a Bentley Continental and a Mercedes-Benz SLS AMG with sirens and light bars? Well, here's the reason. This video shows the fleet on display on the Emirate's roads and highways, while also reaching out to the people the police are meant to protect. It's an impressive display of machinery, to be sure. Alongside the Bentley, Bugatti and Mercedes, we spy a Ferrari FF, a Brabus G-Wagen, a BMW M6, a Nissan GT-R, an Audi R8 and a McLaren MP4-12C (although the latest Dubai Police car, the Lexus RC F, is absent). The video even has a very cinematic look and feel to it, which works well with the night scenes and the blues-and-twos of the exotics cruisers.
