BMW's hybrid M5: A 727 HP powerhouse with a 2,500 kg curb weight

Under the hood, we still find a V8 engine, now supported by a plug-in hybrid system. The setup adds significant weight, resulting in a shocking curb weight.

Electrification and increasingly stringent emission standards force sports car manufacturers to adopt unconventional solutions. A common approach is combining large combustion engines with additional electric units. BMW has also followed this path, creating the new M5.

Under the hood of the aggressive sedan, we find the well-known 4.4-litre V8, which alone generates 585 HP. To this, we must add the electric support of an additional 197 HP. The total power output is 727 HP, and the maximum torque is an impressive 738 lb-ft.

These parameters translate to 0 to 97 km/h in 3.5 seconds and a 250 km/h top speed. Those who opt for the optional Drivers Package can reach 306 km/h. More than good performance comes with driving on electric power alone. The 18.6 kWh battery allows up to 69 km on a single charge.

Unfortunately, it adds significant weight, resulting in a curb weight of around 2,500 kilograms. Until now, this level has mainly been reserved for large SUVs and minivans.

The variable-ratio M Servotronic steering system and the rear axle steering system should help tame such weight. There are also brakes with floating discs, which can optionally be ceramic. Additionally, BMW has employed many electronic tricks, such as the ability to direct power completely to the rear axle and multiple driving modes.

All of this is packaged in a body style we've become accustomed to, which looks really good, dressed in an aggressive aerodynamic package. The "Isle of Man Green" paint is also worth noting, as it is already known from other "M" models. There's no shortage of carbon fibre outside and inside the cabin.

BMW also plans a wagon variant, which we should see in the coming months. It seems the popularity of the smaller M3 Touring has sparked the Germans' imagination.
