BMW X6 SP6 X by Sportec

Swiss tuner Sportec has developed an aftermarket program for the 2013 BMW X6. They focused on the inline-six 3.0-liter diesel engine which in its standard configuration puts out 300 hp (223 kW) and 300 lb-ft (406 Nm) of torque. By remapping the ECU and updating the air intake they were able to lift output to 370 hp (276 kW) and 553 lb-ft (749 Nm) of torque. Thanks to this significant power boost, the X6 is able to perform the 0-62 mph (0-100 km/h) sprint in 5.4 seconds, making it 1.1 seconds quicker than the stock X6 diesel. Top speed is also up from 130 mph (209 km/h) to 164 mph (264 km/h).

Changing gears is now done a lot faster thanks to the revised ratios of the eight-speed Steptronic automatic transmission. Sportec has installed a set of 20-inch OZ lightweight alloy wheels which have lowered the car's curb weight by 40 kg (88 lbs). Lastly, the customized sports exhaust system features carbon fiber tailpipes.

Audi RS3 by Sportec

Sportec has introduced a new tuning package for the Audi RS3 Sportback. Looking tastefully restrained, the model has a stainless steel sports exhaust system, an adjustable coilover suspension (which reduces the ride height by 20-40mm) and 20-inch alloy wheels that cover high-performance Movit brakes. Thanks to a revised ECU, the 2.5-liter five-cylinder engine produces 408 PS (300 kW / 402 hp) and 550 Nm (406 lb-ft) of torque - an increase of 68 PS (50 kW / 67 hp) and 100 Nm (74 lb-ft). If that isn't impressive enough, non-Swiss versions can be tuned to deliver 500 PS (368 kW / 493 hp).

Sportec SP 800 R based on Porsche 911 GT2 RS

This is the Sportec SP 800 R, based on the Porsche GT2 RS.

Aerodynamic touches are light, as Sportec only fits the range-topping (and fastest production 911 ever) with their own front lip spoiler and rear spoiler - all in carbon fiber, of course.

Under the hood, the 3.6 liter flat-six now delivers 800 PS (588 kW / 789 bhp) and 900 Nm (664 lb-ft) of torque over the series' 620 PS (462 kW) thanks to a new hybrid turbocharger, sport camshaft, sport intercoolers, new connecting rods, sport air filter, and an ECU-remap. Also helping with output is the new titanium sport exhaust.

All told the extra power is good for a 0 to 100 km/h sprint in 3.1 seconds while top speed is a more-than-breezy 373 km/h (232 mph) - substantial bumps over the production model's 3.5 second run and 330 km/h (205 mph) top speed.

Replacing the series model's 19-inchers are the Sportec Mono/7 alloy 20-inch (ET40) wheels with central locking and Cup tires - in dimensions 9 x 20-inch and 12 x 20-inch, with 245/30/R20 und 315/25/R20 tires, front and back, respectively.

The SP 800 R gets a suspension lowering of 25 mm for increased downforce too.
