G-Power has taken the latest BMW M5 and pushed it into four-digit territory, giving the G90 super-sedan up to 1,013 PS and 885 pound-feet of torque through its GP-1000 package. In American garage talk, that lands right around the magic 1,000-hp mark, which sounds slightly illegal even when it is not. The wild part? The stock M5 already makes 727 hp from its plug-in hybrid V8 setup, but, apparently, that’s not enough for some people. G-Power Finds The M5’s Mean Streak BMWThe new M5 has split opinions since launch. Some fans praise its monster output and daily usability, but others keep staring at the scale, because BMW lists the sedan at 2,510 kg, or about 5,534 pounds. That is a lot of car. It is also a lot of battery, drivetrain, cooling, sound deadening, luxury trim, and “executive sedan that can scare a 911” hardware packed into one body.G-Power clearly saw that mass as a challenge, not a problem. The tuner’s most serious upgrade gives the M5 nearly 300 extra horses over stock. It also raises torque to about 885 lb-ft. That’s obviously important because this car will likely feel most brutal from a rolling start, where traction becomes less of a bar fight and the upgraded V8 can drag the big sedan down the road like it owes money.BMW says the standard M5 hits 62 mph in 3.5 seconds and runs to 124 mph in 10.9 seconds. The tuning firm has not published its own acceleration numbers yet, but the biggest change should show up past highway speeds. The stock car already launches hard, but more power will make the upper half of the speedometer look like a suggestion instead of a limit. The Real Trick Is Keeping It Cool G-Power This yellow beast required much more than just a laptop plugged into the OBD with an operator typing “more boost” and correcting a few symbols here and there. The full GP-1000 setup includes performance software, an ECU unlock, sport downpipes with 200-cell catalytic converters, the company’s GP-Deeptone exhaust, upgraded intercoolers, and available carbon intake parts. The price for the complete hardware-backed package comes to €31,297 before extras such as a V-MAX increase and more intake pieces. That’s about 36,700 in American money.Why all that additional hardware? Modern turbo engines love airflow, but they hate heat. Push more boost through a hot intake path, and the car may feel strong once, then pull timing and calm itself down like a parent at a school meeting. Bigger intercoolers help the M5 repeat its party trick instead of doing it once for social media. The downpipes and exhaust also reduce back pressure, which helps the turbochargers work with less stress.Source: G-Power
