The level of performance we see from cars today is staggering. With automakers striving to increase power and reduce weight for faster sprints, there has never been so many performance cars to choose from. Often, adding horsepower is favored over slimming down, gaining vanity points for brands. However, big output doesn’t always win the race.For example, muscle cars boast high horsepower, but some are heavy. While the 500 hp Ford Mustang Dark Horse is the ultimate Mustang, its near-4000-lb body gives it 279 hp per ton, holding it back from the competition.There are plenty of cars that out muscle the Dark Horse, proving that it’s not all about the ponies. This list includes twelve street-legal cars with better power-to-weight ratios than the 2024 Mustang Dark Horse that can be purchased now. Electric cars, SUVs, pickup trucks, and hypercars are excluded as they play in different leagues. 2024 BMW Alpina B8 Gran Coupe: 285 HP/Ton bmwusanews.com2024 BMW Alpina B8 Specs Alpina takes BMW's already impressive vehicles and turns them up to eleven.
