McLaren shoehorned the F1's V12 into a BMW M5 wagon test mule

Automakers are known to utilize preexisting vehicles as test beds for major research and development purposes. But some of the zombie mashups produced in-house can result in pretty interesting combinations. Case in point, when McLaren was developing its BMW-sourced naturally-aspirated 6.1-liter V12 for the legendary F1, the company put the engine in … a BMW M5 wagon? Yup, you read that correctly. ItÂ’s no mystery that the legendary F1 came with a BMW-sourced V12. That "M70" V12 originated from its placement in the E32 7 Series and E31 8 Series “50” models in the 1980s up through the 1990s. The version that went into the F1, however, is more closely related to the M-tuned "S70" V12 found in the E31 850CSI, which was the pseudo M-variant to the 8 Series that wasnÂ’t officially designated an M model. But it did feature full-fledged tuning from the M Division. On "Top Gear" presenter Chris HarrisÂ’ podcast, "Collecting Cars", Harris interviewed David Clark, the former director of McLarenÂ’s cars for both the road and motorsports between 1994 and 1998. Clark revealed that they took an E34 BMW M5 wagon and shoehorned the S70 V12 into its engine bay as the mule for testing the F1Â’s engine. Clark even said he drove the car himself as they were fine-tuning the V12Â’s engine output. YouÂ’re probably wondering, how the heck did that thing fit? But it isnÂ’t that surprising. The E34 5-Series was designed to house either the BMWÂ’s venerable straight-six or the new-at-the-time V8. And there was room enough to house the V12 as well, particularly since BMWÂ’s V12 was essentially two of its “M20” straight-sixes bolted together at the crank in a vee. When Clark was testing the S70 V12 in the wagon, he and his team ended up with the 627 horsepower and 479 pound-feet of torque the F1 became known for. ThatÂ’s nearly twice the power the production M5's 311 hp and 266 lb-ft at the time. Clark also divulged that the actual prototype mule still exists, but itÂ’s in BMWÂ’s secret collection of prototypes, and itÂ’s never been revealed to the public. He does, however, hope that one day, BMW will open its doors and show off the incredible mashup of an automobile. Until then, youÂ’ll have to rely on the few custom engine swaps done by owners to get a taste of what a V12-powered E34 M5 is like. Rumor also has it that McLaren could be working on a new direct F1 successor with help once again from Gordon Murray.

Recharge Wrap-up: BMW tests AdBlue pumps, Drivr is a Tesla taxi service

BMW is testing AdBlue pumps in Germany. AdBlue fluid is used to remove NOx from diesel exhaust, and it is stored in its own tank within the vehicle. Filling AdBlue is easy enough for drivers to do it themselves, and with the proliferation of diesel vehicles in Europe, a pump filling system could make more sense than using the current hand-held containers. BMW is testing AdBlue pumps at three fueling stations in Munich and Berlin to help develop further AdBlue dispenser technology. Read more at Green Car Congress. Drivr Green Personal Transportation is a Tesla taxi service in Cincinnati. Two former employees of Tesla Motors founded the startup, which bills itself alongside ride-hailing services like Uber and Lyft. Customers book a ride online, and are picked up by a Tesla Model S. The ride costs $2.50 per mile with a $15 minimum. Drivr currently operates three cars with seven drivers, with plans to lease another 10 Teslas and employ up to 30 drivers. The service will also be expanding to Denver soon, according to the website. Learn more at the Drivr website, or read more at Clean Technica. Ford is opening a research and development facility in Silicon Valley. The Ford Research & Innovation Center, which will be located less than three miles from Tesla Motors headquarters in Palo Alto, California, is expected to be one of the automotive industry's largest R&D facilities. "We're driving to be both a product and a mobility company, and ultimately to change the way the world moves," says Ford CEO Mark Fields. Read more at Automotive News. Law firms advising Fisker Automotive have been denied a $2.50-million fee enhancement in the car company's bankruptcy. Brown Rudnick LLP and Saul Ewing LLP were denied the extra fees, as a Delaware bankruptcy judge ruled there is "no evidence" that the firms provided anything more than what they originally expected. In denying the fee enhancement, the judge cited a "very high bar" for such awards. Read more at Law360.

2015 BMW 2 Series Convertible will flip its lid for $38,850

For the most part, they look almost identical to their coupe versions, except that they now boast an electrically folding soft top.
BMW is dropping the top of the 2 Series in early 2015 in the US with convertible versions of the 228i and M235i. They'll make their world debut at the Paris Motor Show later this year and will show their faces on this side of the pond at the 2014 Los Angeles International Auto Show.
