BMW i8

i8 Spyder. Not the sound of a Wurzel expressing hatred for an arachnid, but BMW's roofless, two-seat hybrid concept.

It'll be unveiled at this year's Beijing auto show later this month and is, as you'd imagine, a pretty good sign that Munich's going to give us a drop-top to join the i8 coupe. For those hard of memory, that's the 155mph, 100mpg sportster due to land in showrooms come 2014.


The i8 Spyder concept is a little stinted compared to its coupe brother, though. Under the two-section folding roof it's slightly shorter and there's a more compact wheelbase, suggesting its original proportions - based on the splendid Vision EffecientDynamics supercar of 2009 - have been rethunk.

BMW has kept the swan doors, which swivel up like the wings of a, umm, swan... They're retained thanks to the amount of carbon that's used in the i8's super-stiff passenger ‘Life' cell, which is made from carbonfibre reinforced plastic (CFRP).



Underneath, there's an aluminium chassis with a lithium-ion battery buttered along its length, keeping the centre of gravity nice and low and achieving a 50: 50 weight distribution. It's got the same plug-in powertrain as the coupe, too; a petro-electro melange of 129bhp electric motor driving the front wheels and three-cylinder turbo petrol engine sending 220bhp to the rears (that's 349bhp in all).



Little by little, the production version of the BMW i8 Coupe is coming more into focus, ahead of its launch in 2014. We’ve seen the car in concept form, most recently as a topless, 2-passenger model at the Beijing Auto Show. Prototypes spotted while undergoing road tests have looked strikingly similar to the concept that made its debut at the 2009 Frankfurt Auto Show, wearing the cumbersome BMW Concept Vision Efficient Dynamics label. We’ve even been provided with a sneak peek of the car via a former senior designer at BMWDesignWorksUSA.

This latest i8 Coupe prototype is sporting swirly blue and white paint, and some (temporary) clunky rear taillights that are probably there simply for safety regulations. As we’ve noted, the shape of this i8 is remarkably similar to that of the concept car. Look closely, and you’ll spot some tiny supports connecting the dramatic-looking dual rear wings to each rear fender. That’s an excellent indication the design detail is being readied for production. According to a source at BMW, the i8 Coupe will also retain the concept car’s forward-opening, gullwing-style doors.


Mounted at the front of the i8 is a 131-hp electric motor, while a 223-bhp turbocharged 1. 5-liter 3-cylinder gasoline engine is positioned behind the cabin and drives the rear wheels. Capable of running solely on electric power for approximately 20 miles, the i8 Coupe is expected to return approximately something in the region of 70 mpg. BMW also estimates the i8 Coupe can sprint from 0 to 62 mph in less than 5. 0 seconds—not too shabby for a fuel-sipper!
We’re still waiting for pricing information, though it seems a range of $150, 000 to $200, 000 is more than likely when the i8 Coupe goes on sale.
