The standard Porsche 911 Turbo’s 480HP 3.6-liter bi-turbocharged flat six is by no means a slouch, but where there’s power, there’s always space for even more power. Or at least that’s what Porsche tuning specialist Sportec believes. The Swiss based tuner revealed a new version of its 911 Turbo based SPR1 that lifts the 3.6-liter flat six’s output to a staggering 858 horsepower at 8,200 rpm and 642 lb-ft of peak torque at 4,800 rpm. Power is transferred to all four wheels through a six-speed manual gearbox.

The new Porsche Panamera made its world debut today in China a few hours ahead of the ‘grand opening’ of the Shanghai Auto Show on Monday, April 20, marking the growing importance of the Chinese market for Porsche and other automakers. The German firm’s first ever sports saloon, which is the fourth model series in Porsche’s range, will be entering the market on September 12 with two engine variants, a 4.8-liter V8-with 400HP available in both rear-wheel and all-wheel drive layouts and a twin-turbocharged 4.8-liter V8 producing 500HP that will be offered exclusively with all-wheel-drive.

Porsche has announced UK pricing of their highly controversial Panamera hatchback will start at £72,266 when it goes on sale September 12.

The base Panamera S costs £72,266 and is available with Porsche’s new Doppelkupplungsgetriebe (PDK) double-clutch transmission which adds £2,289 to the bottom line. Next up is the £77,269 Panamera 4S which features standard all-wheel drive and the previously mentioned PDK transmission. Both models feature a 4.8-liter V8 engine that produces 400bhp and 500 Nm of torque which is good enough to allow the 4S to reach 0-62 mph in five seconds flat (5.4 seconds for the Panamera S).

Mansory acquired Rinspeed’s Porsche tuning division late last year, but made no official announcements as to what it planned to do with it. Then again, what else does one do with a Porsche tuning company than…create tuned Porsches?

Mansory has just released the details of its first upgrade kit for the 911 since the Rinspeed purchase. The kit debuted at this year’s Geneva show and is a comprehensive tuning kit with aerodynamic, suspension and engine upgrades, though the press materials are somewhat heavy on flowery words and light on hard numbers or release dates.

For some reason, Porsche tuner TechArt has decided to release an exclusive aerokit for the recently introduced Cayenne Diesel that’s powered by an Audi-derived, 240-horsepower 3.0-liter V6 TDI. Though less extreme than the firm’s other tuning packages, the accessorized Cayenne Diesel definitely stands out. TechaArt’s aero kit includes a front spoiler with additional lights, side skirts, roof spoiler, a rear apron with an integrated diffuser and headlight / tail light trims. All components are made from high quality polyurethane RIM.
