Citroën’s new C4 Cactus Airflow 2L concept

Next month’s Paris Motor Show will see the ultra efficient Citroën C4 Cactus Airflow 2L make its public debut. As the ‘2L’ part of that name suggests, the target was to achieve an average fuel consumption figure of 2.0 l/100km, which equates to 141 mpg.

Although described as a concept, most of the car’s fuel-saving features could easily appear on production models in the near future.

Undoubtedly the most exciting aspect is the innovative Hybrid Air powertrain. This combines a three-cylinder petrol engine with a motor that runs off compressed air rather than the usual electricity.

Other measures include improved aerodynamics. To reduce drag the underside is smoother, the door mirrors are smaller, narrow wheels are fitted and the rear end gains a diffuser as well as a longer spoiler. There are dynamic components too, such as centrifugally-activated wheel shutters, continuously variable front bumper intakes and mobile side deflectors.

Furthermore, the widespread use of aluminium and composites has resulted in a kerb weight of just 865 kg (1,907 lbs). That means the 2L concept is around 100 kg (220 lbs) lighter than a regular C4 Cactus.

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 ...

Zero Congestion Charge

Image
In a rare piece of good news for motorists, the beginning of 2011 saw a change to the London Congestion Charge that could see some drivers now (legally) avoiding the fee altogether. The new Greener Vehicle Discount, which replaces the Alternative Fuel Discount, means that more cars will potentially qualify for 100% off the daily charge. Naturally, there are a couple of caveats that come attached with this generous gesture from Transport for London . The first is that the vehicle needs to be ‘green’. More precisely, it should be Euro 5 emissions compliant and produce 100 grams of CO2 per kilometre or less. Secondly, if you already own such an eco-friendly machine, don’t presume that you can just swan about in central London and not worry about the Congestion Charge. To receive the Greener Vehicle Discount, a car must first be registered with Transport for London, and that involves a £10 annual payment. So, what cars will qualify for the Greener Vehicle Discount? According to ...
