820hp to be exact.
German tuner Gemballa has been giving the Porsche 911 the Avalanche treatment since 1985 with the launch of the 930-based model. Fast forward to 2017, and the aftermarket specialists based near Stuttgart have travelled to Geneva to present their latest take on the 991 Turbo. And what a take it is.
The first order of business was to extract a monstrous 820hp and 700lb ft of torque from the 3.8-litre six-cylinder biturbo unit, thus making it a whopping 280hp and 214lb ft stronger than the stock engine. In order to achieve these staggering output figures, the engineers had to make some substantial changes. From new turbochargers and bespoke intake manifolds to a high-performance air filter and tweaked cylinder heads, the engine has been thoroughly upgraded. The gearbox also had to be adapted to cope with the added muscle.
After unlocking so much power from the heavily tuned Porsche, Gemballa installed an adjustable sport chassis and forged 21-inch wheels wrapped in 255/30 ZR21 front and 325/25 ZR21 rear tyres. To match the extra oomph provided by the engine, the body has been given a more aggressive look. It’s a substantial 62mm wider at the front and a full 100 mm (3.9 inches) fatter at the rear to make room for the increased track width and those huge alloys.
Some of the new body bits and pieces have been dipped in carbon fibre to keep the weight low, while the tailor-made side skirts come to boost aero much like the gargantuan wing at the back. The sports exhaust system encompasses four end pipes resembling small cannons ready to unleash the 820 firepower.
As for the cabin, Gemballa points out this 911 Turbo Avalanche “would not be an Avalanche without an opulent refined interior.” A two-tone black and white leather upholstery adorns many of the surfaces and it has been combined with Alcantara accents and some carbon fibre touches for some extra pizzazz.
Fitted with all the bells and whistles, the new 2017-spec Avalanche based on the Porsche 911 Turbo (991) will set you back a hefty €389,600 (about £340,000). That’s more than double the starting price of a standard 991 Turbo.
