BMW mulled ten, eight, and six-cylinder engines for i8 before going hybrid

There's little doubt that the 2015 BMW i8 is one of the most radical and groundbreaking performance cars this industry has seen in a long time. From its unique carbon-intensive construction to its 1.5-liter, three-cylinder and electric motor plug-in powertrain to its concept-car appearance, the flagbearer for BMW's new i venture challenges the very notion of what it takes to be a supercar.
Yet apparently the i8 almost didn't do that at all. Yes, it probably still would've had innovative assembly techniques, serious performance and come-hither bodywork, but according to a new report in the Telegraaf, it was very nearly a much more conventional beast, drawing its power from a V10 engine. According to the report, that line of development never got much beyond the drawing board, but BMW engineers then shifted their focus to both V8 and six-cylinder motivation, going so far as to build prototype cars. The higher cylinder-count engines were eventually dropped altogether after BMW decided to turn the i8 into a hybrid, with the six-cylinder reportedly nixed due to heat management and weight issues. In the end, of course, BMW went with the PHEV powertrain that offers a total system output of 362 horsepower and 420 pound-feet of torque - plenty of thrust for this lightweight, all-wheel drive coupe while still enabling an incredible 94 miles to the gallon on the EU cycle. Regardless of how it turned out, it's still fascinating to think that BMW didn't have a much firmer conceptual idea of what it was after when it started the i8's development.
Here at Autoblog, we're genuinely thrilled about this new generation of greener hybrid super- and hypercars, a movement spearheaded by the i8, Porsche 918 Spyder, Ferrari LaFerrari and McLaren P1. But even so, our inner-gearheads can't help but wonder what might have been had BMW pursued a more conventional i8, either in place of, or in addition to, the car they did build. What do you think?

BMW i3 starts near $35,000; NA first deliveries January 2014

While in Germany at the first early pre-production drives of the hotly anticipated BMW i3, BMW people finally hinted at a price ballpark. Numbers being tossed around by pundits have actually been pretty close to what BMW is discussing internally - between $35,000 and just over $40,000. We have been assured now that the base price, should one choose to buy and not lease in the Euro zone, is just over 35,000 euro, with some big taxes included in that price. In the US, the starting price for the fully EV plug-in version should be $34,500 or right thereabouts. In addition to new pricing, we've also gotten our best-yet look at the i3, with the freshly uncovered spy shots you see here.
European deliveries begin in November of this year for the fully electric version of the rear-wheel-drive i3 with 168-horsepower and 184 pound-feet of torque. The e-motor mounted over the rear axle is supplied with energy by the 22-kWh lithium-ion battery pallet under the passenger compartment. Recharging happens in any of three ways: public or personal garage plug-in charge station (garage version not included in the price), the onboard system's Pro Eco mode that adds resistance to the drivetrain in a type of rolling brake energy recuperation, or through the normal brake energy and off-throttle coasting regeneration more common to EVs. Range on a full charge of this drivetrain is said to be upwards of 100 miles under hyper-miling conditions.
Perhaps the best bit of news is that the alternative, range-extending, two-cylinder 600cc engine supplied by BMW Motorrad for the hybrid version of the i3 - mounted in the rear together with the e-motor - will add only 2,000 euros in Europe and about $2,000 in the US. This is a range-doubling solution that could have brought a much higher price gouge, so thank you, BMW. The hybrid e-drive i3 version arrives a couple months after the full-EV launch version. Remember that, unlike the very similar system for the Chevrolet Volt, the system in the i3 supplies no mechanical torque to the driven axle and is only used as a generator (a system BMW first used last year in the 1 Series-based Active ). The US is seen as the clear number one market for the i3.

BMW celebrates 30 years of M5 with 600-hp super sedan

It's been 30 years since BMW rolled out the first M5, and while displacement and cylinder count may have fluctuated over those past three decades, output has only increased. The first-generation E28 M5 packed a 3.5-liter inline-six with 252 horsepower and 243 lb-ft of torque. The second-gen E34 model that followed added an extra 100 cc (and later 200 more) to produce 310 hp and 266 lb-ft. The E39 followed with a 4.9-liter V8 churning out 394 hp and 369 lb-ft, replaced by the award-winning 5.0-liter V10 in the E60 with its 500 hp and 380 lb-ft before BMW rolled out the latest model with a 4.4-liter V8, its twin turbos making up for the two dropped cylinders and 600 cc of displacement to produce 560 hp and 502 lb-ft of torque. But even that's being left in the dust by the new special edition you see here.
The 30th Anniversary Edition BMW M5 packs that same 4.4-liter twin-turbo V8, but cranks the output up to a nice, round 600 horsepower and a solid 516 lb-ft of torque to go with it. That makes it more powerful, not only than any M5 that's come before it, but also any of its rivals. The Jaguar XFR-S and Audi RS6 Avant (the latter only available as a wagon and not in North America) both lag behind this ultimate of Ultimate Driving Machines; only the Mercedes-Benz E63 AMG trumps it on torque (but not on power), with 531 lb-ft in stock form and 590 in the S-Model.
As a result, the 0-60 time drops from a quoted 4.2 seconds in the stock M5 to a scant 3.7 in the 30th Anniversary edition (just one tick behind that twistier E63 S). The special M5 also comes with the Competition Package as standard, as well as a dedicated control module for the Active M Differential, a special Frozen Dark Silver matte finish, 20-inch alloys and black chrome badges. Special badges abound inside as well, where you'll also find black leather and Alcantara upholstery and aluminum trim. There'll even be a dedicated one-day course offered to owners at The Thermal Club in Palm Springs, CA, to further sweeten the deal.
