BMW Motorrad unveils e-Power Roadster prototype, generates 1500 Nm torque!

BMW Motorrad has unveiled the prototype version of its all-electric motorcycle called the E-Power Roadster. The first startling fact about this electric monster is that the motor powering it generates 1500 Nm of torque - that's as much as a Bugatti Veyron Super Sport. Resting heartbeat or torque is 200 Nm but once it's gone through the single-speed step-down gearbox, BMW say it has an effective torque of 1500 Nm. So far, it looks like a parts bin with a face from an S1000R, drive from an R1200RS and the frame has been custom-built to fit the giant powertrain borrowed from the China-only LWB BMW 7-Series, and the battery pack comes from a 2-series plug-in hybrid.

E-Power Roadster currently weighs 290 kg in its prototype version which compared to a production-spec Zero SR/F which weighs 228 kg is not so bad - considering by the time E-Power reaches production level, BMW should be able to make it shed about 30 kg.

It's weight should not be a trouble for how it'll pull forward given the torque figures which are enough to propel it to 100km/h in 2.9 seconds - that's only about .2 seconds slower than a BMW S1000RR.

The BMW electric roadster will be capable of fast charging which should charge it to full in under one hour. One limitation to this time is heat - once the temperature rises above 40C, charging slows down. BMW are working to improve the cooling system aiming to achieve 5.9 km of charge per minute so a 30-minute charge should be good for 178 km.

The E-Power Roadster is a long way from hitting production and BMW have said that the bike needs to have 200 km of range and so it won't be released unless 200-300 km of real riding is achieved on a full charge.

Some engineers sure had fun playing around the leftover parts in the catalogue to create a tire shredding BMW chimera.

Parts optimization may help in shedding quite a bit of weight and further iterations in design and mapping will make it user friendly.

Using forms of RAM intake to cool down the battery pack in conjunction to the conventional radiator/fan setup.

Using Regenerative braking to recharge and multiple maps and power settings to use in different world conditions.

Watching the progress of this parts bin special.
