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.

Protonic Red BMW i8 will bow in Geneva

BMW will unveil special edition versions of the i8 at the Geneva Motor Show, but we hope the rest of the company's offerings are more exciting than its first one – the new Protonic Red Edition. BMW bathes this limited edition i8 in the eponymous red and paints some the trim Frozen Grey metallic. The company finishes off the exterior improvements with 20-inch W-spoke wheels that it decorates Orbit Grey metallic with Aluminum matte hubs. The interior upgrades amount to red double-stitching around the cabin and the addition of some carbon fiber and ceramic trim. There are no mechanical changes. It's hard to get too excited about special paint and trim, but if you are in the market for a more colorful i8, then the Protonic Red Edition seems like a good opportunity. Production begins in Leipzig in July. Related Video: Comfortably exceeding expectations: BMW i8 is the world's highest-selling hybrid sports car. Exclusive BMW i8 special editions. Protonic Red Edition gets the ball rolling at the Geneva Motor Show. Munich. Last year, global sales of the BMW i8 exceeded the combined figure of all other hybrid sports cars produced by other manufacturers*; 5,456 units of the i8, which is powered by the combination of a three-cylinder turbocharged engine and an electric drive system, were sold worldwide in 2015. The car's innovative plug-in hybrid technology delivers system output of 266 kW/362 hp (fuel consumption combined: 2.1 l/100 km [134.5 mpg imp]; CO2 emissions combined: 49 g/km)**. "The success of the BMW i8 speaks for itself," said Ian Robertson, BMW AG Board Member for Sales and Marketing. "It is already the world's most successful hybrid sports car and has comfortably exceeded our own expectations. I can think of no better illustration of the relevance of our young BMW i brand." And the BMW i8 is about to add further lustre to its appeal with exclusive special-edition models poised to be unveiled for the first time at the Geneva Motor Show. The new arrivals present customers with even more ways to own a very individual car. BMW i8 Protonic Red Edition will be built in Leipzig from July. The first in this line of special-edition models is the BMW i8 Protonic Red Edition. Like those set to follow in its tyre tracks, it is only available for a limited period.

Genesis G70 vs sport sedan rivals: How it compares on paper

We got our first look at the Genesis G70 sport sedan today. We think it looks good, with enough ties to its fellow Genesises (Geneses?) to further establish the brand and just enough distinction to help it stand out from the crowd. But ah yes, the crowd. Although Genesis didn't release the G70's full spec sheet, it revealed just enough for us to start sizing it up to its future competition. There are certainly others with which to compare (Lexus IS, Cadillac ATS, Alfa Romeo Giulia, Jaguar XE just to name a few), but we decided to take a look at the best sellers and most competitive luxury sport sedans. (And hey, if you like this, we can always do a follow up) So, here we have the Genesis G70 vs BMW 3 Series vs Audi A4 / S4 vs Mercedes-Benz C-Class vs Infiniti Q50. Nothing like a good chart to dig your teeth into on a Friday. Note that we only compared those models that line up with the G70. So, we left out the BMW 320i and Audi A4 Ultra entry level models as well as the Q50 3.0t mid-grade model that's considerably cheaper than the German performance upgrade models we listed. All 0-60 figures are rough estimates based on several sources, models/drivetrains and OEM figures.
