Audi TT ultra quattro concept

Audi has revealed the TT ultra quattro concept, which is due to debut at the forthcoming Wörthersee event in Germany.

Based on a regular TT 2.0 TFSI Coupé, its weight has been slashed by 300 kg (661 lbs) to just 1,111 kg (2,449 lbs). Power meanwhile is up to 305 bhp (228 kW / 310 PS).

That diet was mainly achieved through changes to the bodyshell. Carbon fibre-reinforced polymer has been used for the transmission tunnel, roof panel, B-pillars and the rear end, plus magnesium features in the floor.

Further measures include the fitment of a titanium exhaust system, CFRP and aluminium wheels, ceramic front brake discs, fibreglass-reinforced polymer suspension springs and a small lithium-ion starter battery.

Given the vastly improved power to weight ratio, performance is naturally much more impressive than the standard car’s. Acceleration from rest to 62 mph (100 km/h) takes only 4.2 seconds, while the top speed rises to 173 mph (278 km/h).

The good news is that Audi is saying the TT ultra quattro concept could preview some similarly lightweight, low-volume production models.

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 ...
