G-Power M3 Tornado RS with 720 HP

German tuner G-Power has come up with its most powerful version of a BMW M3 yet - the M3 Tornado RS.

The power-tuning kit consists of the SK III "Sporty Drive" supercharger system which dials output on the V8 to a more than sporty 720 PS (529 kW / 710 bhp) and 700 Nm (516 lb-ft) of torque.

All that power makes for some healthy numbers with the M3 Tornado RS now doing the 0 to 100 km/h sprint in just 3.7 seconds and reaching 200 km/h (124 mph) in 9.5 seconds. Top speed is over 330 km/h (205.5 mph).

The SK III "Sporty Drive" Supercharger System is priced at €35,000 not including installation.

speedART PS9-300D based on the Porsche Panamera Diesel

German tuner speedART has developed a tuning kit for the Porsche Panamera Diesel which is turned into the PS9-300D.

The power kit dials output on the 3.0 liter V6 diesel unit to 300 PS (221 kW / 296 hp) and 650 Nm (479 lb-ft) of torque from the series' 250 PS (184 kW / 247 bhp) and 550 Nm (406 lb-ft).

The PS9 aerodynamic kit is also part of the package with a front chin spoiler, side skirts, rear diffuser, a double wing rear spoiler, and new front and rear air intakes.

Twin tailpipes are added too and the 22-inch Five Spoke Competition mono-block wheels, with 265 tires at the front and 305 tires at the rear, mask the sport-design brake calipers.
