Inertia is a b*tch. "That which is at rest, tends to stay at rest. That which is in motion tends to stay in motion. The heavier a body is, the more force that is required to initiate/increase -- or decrease -- momentum of that body."
Curb weight of 2020 Ford Mustang Ecoboost is 3,532lbs. and produces 310 horsepower and 350 lb-ft of torque.
Curb weight of the base 2.0-liter turbocharged 5-cylinder 2020 Chevy Camaro is 3,696 lbs. and produces 275 horsepower and 295 pound-feet of torque.
Curb weight of the Elantra GT N-Line w/ tech pkg is 3,067 lbs. (making it almost 500 lbs lighter than the 'Stang and over 600 lbs lighter than the Cammy) and produces 201 horsepower and 195 lb-ft of torque, OEM-spec. With the TDI Tuning turbo tuner, HP & torque rise to 251 WHP and 240 ft-pounds of torque...
So, yeah, I'm quicker to cruising speed by a comfortable margin. Of course, driver skill plays a part and most of the "big meat" drivers' style equates to 'stomp on pedal, shift at/above redline', with no appreciation of power/torque curve 'sweet spots'. Do I drag race it at a track in the 1/4 mile, against anything
? No, never. Do I ever go above speed limit + 10%? No, never. But with the safe, removable turbo tuner, the g-force on acceleration is incredible...
Again, I'm now completely satisfied with this Hyundai 'sleeper' hot hatch, and I come from Fiesta STs (my
curb weight less than 2,500 lbs.) -- also Ken Block's preferred 'sleeper' hatch -- which they no longer sell in the Americas. Used to whip Camaros and 'Stangs in them, too. Almost beat a Lexus RC F 2-DR AWD coupe in a FiST, once, from a stop light. Lost by half a car-length, straight-line to 70 MPH (before my 80° on-ramp), but got a thumbs up out of his drivers' side window for the effort. He was a proficient driver in a $70K sports car, so I didn't mind at all... Most drivers are effectively asleep at the wheel and/or just plain ignorant of vehicle dynamics and easy pickings on the street.
Know what Formula 1 designers spend millions of dollars on, trying to make their cars faster? HP/Torque, you might guess. Nope. Weight reduction and drag coefficient!
Wanna make your car faster? Go with lighter rims/tires. This is called 'unsprung weight' and reducing it has the effect of reducing gross weight by an equivalent of 4 lbs. per pound reduced. So, changing out the OEM ~47 lb. rims/tires for Enkei Racing RPF1, 17 1/2-lb rims and low rolling resistance Continental ExtremeContact DWS 06 PLUS 225/40ZR18 coming in at 40.5 lbs per rim/tire... times 4 for each wheel... x 4 for lower unsprung weight = an 104 lb. effective weight reduction for acceleration, braking and cornering. It's the best c. $2,000 you'll ever spend; just keep the perfectly trashy OEM rims/Hankook's for backups... Additionally, you could lose some body weight, too, fatboys.
Helpful evidentiary links:
Why does wheel weight matter? Lightweight wheels can have a huge effect on any vehicle's acceleration, braking, and cornering abilities.
