BMW i technology ends up on an HNF e-bike

Electric bicycle manufacturer HNF is using an innovative drive unit swing arm on its latest model, the Heisenberg XF1. The component, which was originally developed and patented by BMW's 'i' division, brings some significant benefits.

For example, integrating the swing arm, Bosch electric motor and lightweight Gates carbon fibre drive belt means full rear suspension can be fitted. Furthermore, there's no need for a belt tensioner because the motor's spindle position relative to the rear wheel is always constant.

At the system's core is a complex four-bar mechanism that links a frame-mounted Rock Shox damper to the other elements. This solution allows up to 150 mm (5.9”) of suspension travel, plus the swing arm won't stiffen under hard acceleration. Consequently, HNF says grip and traction can be maintained regardless of the terrain.

In Germany the HNF Heisenberg XF1 costs from €8,345. That's around £5,900 at current exchange rates.

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 ...
