BMW E-Scooter concept

Following its Concept C maxi scooter that was unveiled at last year’s Milan bike show, BMW has now revealed the E-Scooter concept. And, as the ‘E’ in the title suggests, it’s electrically-powered.

With any electric vehicle, a critical question is going to be how far it can travel between recharges. For the E-Scooter, BMW is aiming for a range of at least 60 miles (100 km) thanks to a high capacity battery. Recharge time from a fully discharged state will be about three hours.

By comparison, existing electric scooters such as the Econogo Yogo can travel a maximum of 44 miles (70 km), although bikes with larger battery packs will manage more. The Brammo Enertia Plus motorcycle, for example, has a range of 80 miles (128 km).

Given the urban environments in which the E-Scooter will predominantly be used, performance has also been an important design factor. Consequently, BMW’s target has been to match the acceleration of a 600 cc petrol-engined maxi scooter.

An unconventional aspect of the E-Scooter is its construction. While scooters usually have a central frame to which everything is attached, the BMW does without one. Instead, the aluminium battery casing assumes that role, supporting the rear sub-frame, swing arm and front forks.

Drive from the electric motor to the rear wheel is via a belt system. An added benefit is that under deceleration or braking, this set-up acts as an energy regenerator, extending the scooter’s range by between ten and twenty percent.

As it’s just a concept for now, there’s no word on whether the BMW E-Scooter might make it into production. Undoubtedly one of the important issues would be cost, which is something that that high capacity battery unit might be having a significant impact on.

Saab 9-3 Aero Carlsson

Image
Saab has got experience of producing special editions in honour of rally driver Erik Carlsson, having previously named versions of the 900 and 9000 after him during the late 1980s and early 1990s. Now it has decided to do it again, this time to mark the fiftieth anniversary of the Swedish driver’s first win in Britain’s RAC Rally, which was achieved at the wheel of a Saab 96. Thankfully, the company has resisted the urge to just bung some fancy alloys and a few other extra bits onto something like a mid-range diesel model. Instead, it appears to have resurrected the limited edition Turbo X from a couple of years ago, as the new edition similarly features a turbocharged 2.8 litre petrol V6, Saab’s XWD all-wheel drive system and a six-speed automatic gearbox. The result is the 9-3 Aero Carlsson saloon, which turns out to be a very rapid car. With 276 bhp (205 kW / 280 PS) and a healthy 400 Nm of torque, the 0-60 mph (96 km/h) dash takes just 6.9 seconds. But it’s in the mid-range t...

American spec Fiat 500

Image
Fiat has released the first details and images of the North American specification 500. The tiny city car will be available in Pop, Lounge and Sport trim levels, and is distinguished from the European version by its more aggressive front and rear bumpers, bigger grille and flared sills. Another unique feature is the engine. Fiat has decided to use the 1.4 MultiAir unit currently found in models such as the Fiat Punto Evo and Alfa Romeo MiTo. Perhaps it felt that using the forthcoming two-cylinder TwinAir in the American 500 would have been too much for markets there to take? There’s no word yet on what power output the MultiAir will have, although in its current applications it comes with either 103 bhp (77 kW / 105 PS), 133 bhp (99 kW / 135 PS) or 167 bhp (125 kW / 170 PS). Similarly, prices have yet to be confirmed, but hopefully both details will have been sorted out by the time the order book for the 500 hatch opens later this year. For convertible fans, the 500C is due ...
