Engineering the BMW i8 Spyder is presenting major challenges for its development team, say BMW officials
18 December 2013

The BMW i8 Spyder is presenting "major challenges" to engineer, company officials have told Autocar.

A spokesman said that incorporating the carbonfibre-reinforced plastic bodyshell construction of the i8 into a convertible format was proving problematic: "The last architecture presented some fairly major challenges, to be able to produce a convertible in that format. The rigidity was hard to find with that particular architecture."

The spokesman also confrmed there is "no set time frame" for the market introduction of the i8 Spyder.

That contradicts media reports which have stated a late 2015 launch for the i8 Spyder. A BMW i forum reports that BMW officials gave the green light to the project last week after seeing a late-stage development prototype. 

The i8 Spyder will reportedly use the same hybrid electric powertrain as the i8 coupé. That means a three-cylinder engine and generator mounted behind the rear seats and driving the rear wheels, with an electric motor driving the front wheels. In total, the i8 coupé develops 228bhp, with BMW claiming it can hit 62mph in 4.4 seconds.

At the concept's debut at the 2012 Beijing motor show, BMW said the i8 Spyder would make production in 2015. These development challenges would appear to threaten that timeframe.

Another German car whose lack of engineering integrity and foresight is now causing development and forthcoming production issues. This would never happen with a Japanese or British marque. If McLaren, for example, were developing the i8, there wouldn't be an issue like this.

Design it like a plastic cup – and it will behave like a plastic cup.

I like you! You live in a world of your own. I wish I could do that!

At least we know they will not release it until it is perfect. Now tell me why the F-type comes in at over 680 pounds heavier than the Boxster S...... not enough development time ? Why does a new "larger" Range Rover need to be built to accomodate "luxury" when the original is as big as a barn..... not enough development time?

BMW's website claims, in total, the i8 develops 266kW which equals 362hp (356 imperial horsepower).
