G-Power Storm: A 725HP and 215MPH BMW 760i

In the tune-tastic world of G-Power, all stock BMWs are underpowered and sluggish and in need of some serious cosmetic makeup. Having already taken on the M5 sedan, M3 Coupe, M6 Coupe, Z4 Roadster and the X5M and X6M SAVs, just to mention a few, G-Power has now turned its tuning affection on Munich's flagship limo, the 760i and its long-wheelbase sibling, the 760iL.

Simply called the Storm, G-Power's latest achievement will be produced in a limited run of just 10 units worldwide and it promises to bring the rain on other tuning proposals like the 500HP Alpina B7.

Starting with the engine, G-Power's technicians fiddled around with the 6.0-liter V12 bi-turbochargers increasing maximum boost pressure from 0.5 bar to 0.9 bar. They also recalibrated the ECU, added larger injection valves and created an entirely new exhaust system.

The result is a maximum output of 725 horsepower at 5,500 rpm and a peak torque of 1,000Nm or 738 lb-ft from 2,000 rpm, up from the stock engine's 544HP and 750Nm or 553 lb-ft.

Power is transferred to the rear wheels through a modified version of the 760i's eight-speed automatic transmission.

G-Power claims that the Storm is capable of accelerating from 0 to 100 km/h (62mph) in just 4.2 seconds, to 200km/h (124mph) in 11.9 seconds and reach a top speed of 345 km/h or 215 mph.

The engine modifications are accompanied by a new sports suspension that lowers the limo's ride height by 30 mm or 1.2-inches.

The Storm also features a full body kit that includes a new bonnet made of Kevlar with air vents, unique front and rear bumpers and carbon fiber side skirts, boot lid spoiler and rear diffuser.

The four tail pipes and the new 22-inch lightweight alloy wheels shod in Michelin rubber size 265/30 at the front and 295/25 at the rear, complete the exterior changes.

G-Power only released a couple of renderings of the exterior, but the tuning firm said that it has refined the interior of the 760i with a new "ergonomically shaped" sports steering wheel, a different speedometer and carbon fiber trim for the door panels, central console and dashboard.

The fully converted Storm 760i is priced at a hefty €365,000 or at today's exchange rates, US$495,500, while the long wheelbase 760il Storm, from €375,000 or US$510,000.
