G-Power have decided to give the M340i xDrive needed a little more power and is now offering three levels of power for the performance 3er.
The M340i xDrive is the range-topping offering from the BMW 3 Series lineup and with 382 hp (275 kW) and 500 Nm of torque on tap, it is not exactly a slouch.
For starters, there’s the entry-level GP-420 package, which boosts the output to 420 hp (313 kW) and 442 lb-ft (600 Nm). That’s purely a software massage for the inline-six engine with no hardware upgrades. If you want more power, you’ll have to go for the GP-470 kit, which also includes a performance exhaust system with a new catalytic converter for a peak power of 470 hp (350 kW) and 479 lb-ft (650 Nm) of torque – already above the M3 (F80) levels.
This brings us to the flagship offering – the so-called GP-510, which – as its name implies – increases the output to the incredible 510 hp (380 kW) and 509 lb-ft (690 Nm). That’s possible thanks to a new engine management software and a bigger turbocharger, in addition to the previously mentioned hardware upgrades. G-Power even offers to unleash a higher top speed of 186 mph (330 kph).
In terms of acceleration, the base package promises to cover the 0-62 mph (0-100 kph) run in 4.0 seconds, while the GP-470 will go below the four-second mark (3.8 seconds). A further 0.1 seconds improvement comes with the most expensive option.
