Most powerful GMC cars

The key to performance is power. Even heaviest sedans and SUVs can beat lightweight sports cars, if they have enough engine power.

Advanced fuel injection systems and high precision manufacturing is allowing for ever increasing power output and higher performance.

Advancement in battery technology and power electronics also brings electric cars amongst the most powerful of all time. Some examples are claimed to produce over 2000 horsepower - well over a megawatt!
