Ferrari 458 Italia tuned into Mansory Siracusa

Tuner Mansory has brought the Siracusa to the Geneva auto show halls - based on the Ferrari 458 Italia.

Named after a town in Sicily and its historic race track, the Mansory Siracusa makes even more use of carbon than does original manufacturer Ferrari as all body components are now made out of that lightweight material.

Those include a front apron with air inlets for the front coolers, a new bonnet, and side skirts with integrated ducts to feed even more cooling air to the engine. At the back is a rear skirt with integrated diffuser and a rear wing. Carbon blades replace the rear window and the total tally on the weight-saving carbon is 70 kg (154 lbs) less curb weight for the 458 Italia.

Power upgrade takes the form of an ECU remap, sport air filer and sport exhaust - all good for 590 PS (434 kW / 582 bhp) and 560 Nm (413 lb-ft) of torque. 0 to 100 km/h takes place in 3.2 seconds and top speed is 330 km/h (205 mph).

For the suspension, Mansory fits four sport shock absorbers and progressively-wound lowering springs which lower the 458 by 20 mm. Wheels consist of 9 x 20-inch and 11 x 21-inch forged rims wrapped in Michelin PS2 tires, 245/35ZR20 and 305/30ZR21, front and rear, respectively.

Inside the cabin, the tuner applies top materials including leather, ultra-suede and carbon for the interior finish. That includes handiwork such as the decorative stitching, a newly designed center console, aluminum pedals, and a sport steering wheel with full-sized airbag.

BMW B5 Bi-Turbo by Alpina Touring at Geneva

BMW tuner Alpina has brought the B5 Bi-Turbo Touring to the Geneva auto salon.

The B5 Bi-Turbo Touring is based on the BMW F10 5-Series 550i and has beaten the upcoming M5 to the punch in more ways than one.

Last summer, Alpina released the B5 Bi-Turbo sedan variant. Almost a year later, though still ahead of the M5, comes this touring/wagon bodystyle B5 featuring nearly identical specs as the sedan. The 4.4 liter twin-turbo V8 gets its output dialed up a few notches to 507 PS (373 kW / 500 bhp) and 700 Nm (516 lb-ft) of torque - exactly 100 PS (74 kW / 99 bhp) and 100 Nm (74 lb-ft) more than the series'. Gearbox is the ZF eight-speed SWITCH-TRONIC automatic.

In terms of performance the B5 Bi-Turbo Touring does the 0 to 100 km/h (62 mph) sprint in 4.8 seconds (4.7 for the sedan) and reaches an electronically limited top speed of 300 km/h (186 mph).

The extra power takes a small toll on fuel-economy which comes in at 10.9 liters/100 km (10.8 on the sedan).

Mercedes SLS AMG - BRABUS 700 Biturbo

The Brabus 700 Biturbo, based on the Mercedes-Benz SLS AMG, has hit the floor at the Geneva auto show today.

Engineers at the German tuner have devised their own twin-turbo system to fit to the SLS's V8 engine to achieve an output of 700 PS (514 kW / 690 bhp) and 850 Nm (626 lb-ft) of torque. The B63 bi-turbo system features a left-turning charger attached to the left side of the engine, as opposed to most right-charging, right-side fitted twin-turbochargers. This type of fitting allows for improved gas flow and dynamics.

Brabus also provides an intercooling system, performance exhaust manifold, sport air filter system, does an ECU remap and fits its own forged pistons that reduce the compression ratio to 9.0:1.

The new performance exhaust system is also a Brabus in-house creation made of ultra-light titanium and features four slanted tailpipes 84 mm in diameter.

Final performance figures: 0 to 100 km/h (62 mph) is 3.7 seconds, 200 km/h (124 mph) is reached in 10.2 seconds and top speed is 340 km/h (213 mph).

A wide-body kit (WIDESTAR) is fitted that widens the SLS at the rear axle by 20 mm. There's also a front spoiler, rear spoiler lip on the trunk lid and a rear diffuser. Gills are fitted to the front fender with blue-illuminated Brabus lettering.

Wheels are Brabus's own 9.5J x 20-inch rims, with 275/30 ZR 20 tires, for the front axle, and 11J x 21-inchers wrapped in 295/25 ZR 21 tires at the back. Tires are supplied by Pirelli or Yokohama.

A Bilstein suspension kit lowers the SLS by 30 mm while Brabus sport stabilizers are added to the front and rear axles for improved stability.

On the inside is a new sport steering wheel, a 400 km/h (250 mph) speedometer, matte or shining carbon-fiber trims in a variety of colors, as well as matte anodized aluminum pedals and foot rest.
