Put down your whiteboard, we'll figure this out with a real world experiment.
It's not that gearheads are lazy at math but let’s be honest, when it comes down to testing out scientific theories and playing with the laws of physics, which do you prefer? A whiteboard and a TI-84 calculator or a drag strip and two Dodge vehicles with SRT badges? Yeah, we thought so, and for that reason we’ll spare you the drawn out Engineering Explained video and answer the question the manual way. So what’s the problem on hand?
Essentially, The Fast Lane Car wants to know which is better in a drag race, horsepower or number of contact patches? Of course, that’s a relative question. You could have an all-wheel drive car with 100 horsepower and it’ll get smoked by a Camaro ZL1. When horsepower on both cars is fairly even, usually the all-wheel drive car wins.
Within the Dodge family, the Jeep Grand Cherokee SRT is the four-wheel drive machine of choice and it makes an impressive 475 horsepower from a 6.4-liter pushrod V8. On the other hand, we already know the Hellcat makes 707 horsepower from a supercharged 6.2-liter V8 as if it were written on the back of our eyelids, but power is going to two tires at the rear that struggle to maintain grip. So who wins between the two Dodge siblings? Watch and learn, but first make note of the fact that the Challenger weighs 500 pounds less than the Jeep, though the SUV has wider tires just in case the race wasn’t interesting enough. Who knows how things will go once the Jeep Grand Cherokee Trackhawk is out.
