Because the previous 700-hp kit was simply not enough...

The BMW X5 M is already a monster of an SUV with 575 horsepower, but tuners still feel the need to extract even more muscle from the biturbo 4.4-liter V8 engine. G-Power launched an upgrade kit back in October last year which dialed the engine to a massive 700 hp (514 kW). Now, the tuners are back to up the power ante to no less than 750 hp (551 kW) and an earth-moving 723 lb-ft (980 Nm) of torque. Compared to a standard X5 M, G-Power’s version has an additional 175 hp (129 kW) and 170 lb-ft (230 Nm.)

For such a large vehicle that weighs 2,350 kg (5,180 lbs), a top speed in excess of 186 mph (300 kph) is downright impressive. BMW’s high-performance SAV will be able to reach that velocity only after G-Power will install its stage 3 kit priced at €4,400 ($4,900) and will remove the stock 155-mph electronic top speed limiter for an extra €668 ($743.)

If you’re wondering where that added oomph comes from, it’s from the upgraded turbochargers, some software wizardry, and a bespoke exhaust system made from titanium which is 23 kg (50 lbs) lighter than the stock one. The BMW X5 M is certainly not the type of vehicle you see often on a drag strip, but G-Power says the tuned version with the stage 3 kit installed will run the quarter mile in 11.5 seconds.

Besides infusing more power in the V8 engine, the tuners have other upgrades available. These include a set of massive 23-inch forged wheels with matching tires from €8,442 ($9,385), a coilover suspension for €2,292 ($2,548), and custom downpipes with catalysts for those willing to spend an extra €3,190 ($3,546.)

These aftermarket goodies are not exactly cheap, but then again neither is the X5 M which kicks off at almost $100,000 in United States and costs just shy of €115,000 in Germany.
