BMW i1 EV rumored, based on electric Mini

With just two BMW i cars currently available — and aging — we've been hankering to know what new EVs are coming down the pipeline for the Bavarian automaker. We've had news of the iNext and i4, caught wind of an iX3, and as BMW is in the early stages of a large electrification push, there has been a multitude of "i"-prefaced trademarks registered. The next we can expect, if the rumors from Spanish outlet Motor.es are to be believed, will be a diminutive i1 EV, based on the same platform as an upcoming electric Mini Cooper. As such, it would share the electric Mini's front-drive/front-motor configuration — previewed on the Mini Electric Concept, shown above, that debuted at the Frankfurt Motor Show last year. It stands to reason that the i1 would be smaller than the high-roofed i3, possibly borrowing the five-door hatchback format from the 1 Series sold in Europe (which would be a long-awaited dream come true if it made its way to the United States). The electric car would be about a foot shorter than the 1 series, though, according to the report, at about 158 inches long. It would be built on an electric version of BMW modular UKL platform. Keep in mind, the BMW i1 is just a rumor at this point, with Motor.es keeping its sources unnamed. If true, though, it could replace the i3 in BMW's lineup five years from now, in 2023.

Thermal imagery of BMW M4 DTM pit stop is red hot

A pit stop is a pit stop, right? The race car pulls in, the crew changes the tires, pumps in some fuel, maybe swaps out a busted body panel or squeegees the windshield, and off it goes for another heat. Only pit stops have become the focus of news lately for a number of reasons, whether it's because of mishaps (like the ones that prompted F1 to ban mid-race refueling), new time records (due largely to said ban) or interesting new ways to film the fast-paced action.
A few weeks ago we brought you footage of an IndyCar pit stop filmed from multiple angles courtesy of Google Glass. Now BMW has released a brief clip of one of its M4 DTM racers coming in for fresh rubber, all filmed by infrared camera. Its the kind of technology BMW uses to help optimize its German touring cars for competition, and now the Bavarian outfit has released some footage for fans to enjoy.
The resulting thermal imagery gives you an idea of how hot the car runs (and where the heat is emanating from), how warm they get the fresh rubber before they get it onto the car, and what kind of temperatures the pit crew is subjected to. Look closely enough in the 25-second video below and you'll even see the heat sputtering out of the exhaust pipes as the M4 downshifts into its pit box. (Just don't try adjusting your speakers, the clip is without audio.)

BMW M3 and M4 will rock 430 hp from twin-turbo six with standard manual [w/video]

We're not sure which spec we're most intrigued by for the new BMW M3 and M4: the twin-turbo six-cylinder with 430 horsepower and "far beyond" 369 pound-feet of torque, the 3,300-pound curb weight or the standard six-speed manual transmission with automatic throttle blipping on downshifts. That engine is fitted with both Valvetronic and Double-Vanos, twin-wire arc-spray coating in the cylinders instead of liners to save weight, a track-ready cooling system with additional radiators, a forged crankshaft, dry-sump lubrication and a magnesium oil sump. BMW says its "high revving concept" has a redline beyond 7,500 rpm.
In the M4, it will be pulling a coupe with "a weight of just under 1,500 kilograms," which is 3,300 pounds to you and me. That number is said to include no driver and 90 percent fuel, but we're still waiting on the exact number and specs. BMW says it's "around 80 kilograms lighter than a comparably equipped predecessor model," putting the power-to-weight ratio at something like 7.68 pounds per horsepower at the same time as it helps reduce fuel consumption by 25 percent. The use of carbon fiber reinforced plastics (CFRP) for the roof, drive shaft (with no center bearing), trunk and front strut brace, and forged aluminum for suspension components, have aided in the weight loss. This time around, the sedan - the M3 - will also get a CFRP roof.
The default option will be a six-speed manual.
