BBR gives MX-5 235 bhp

The Mazda MX-5 is a great little sports car, but the most powerful version currently available features a 2.0 litre engine with a fairly modest 158 bhp (118 kW / 160 PS).

For those who think that that’s not enough, tuner BBR has got together with Cosworth Engineering to provide a fix.


Their solution is to attach a fourth generation Eaton MP62 supercharger, which lifts power by almost 50% to 235 bhp (175 kW / 238 PS), while torque rises from 188 Nm (138 lb/ft) to 257 Nm (190 lb/ft). That puts the BBR-Cosworth MX-5 right on a par with competitors such as the £33,870 Mercedes-Benz SLK 300.

However, the conversion consists of more than just the supercharger. To help the engine breathe better, a Cosworth inlet manifold housing is fitted, together with high-flow calibrated injectors, air box and air filter.


Managing everything is a BBR Auxiliary Interceptor 2010 engine control unit, which has 3-D mapping and a MAP sensor. An air to water intercooler is also included in the package, and competition-grade hoses and fixings are used throughout.

The finishing touches are the BBR-Cosworth identification badges, which are the only external clue to the under-bonnet transformation.

The BBR-Cosworth Mazda MX-5 supercharger upgrade is priced at £4,995.00, including installation by BBR. Kits will also be made available for DIY fitting.

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 ...
