2023 Challenger SRT Hellcat Performance
Two powerful supercharged V8 engines provide the SRT Hellcat with blistering performance. In the SRT Hellcat, the 6.2-liter unit provides 717 hp, and the SRT Hellcat Redeye has an even wilder 797 hp. The special-edition Black Ghost bumps the power even further to 807 hp, the same figure found in the SRT Hellcat Super Stock. While lesser Challengers have available all-wheel drive, these V8 monsters send all of their power to the rear wheels exclusively. This means that traction can be an issue when trying to get the SRT Hellcat off the line effectively, but independent tests have shown that it's possible to get the Redeye to 60 mph in around 3.7 seconds, with the quarter-mile coming up in under 12 seconds. Dodge claims a top speed of 203 mph for the Redeye. With both of these cars, the driver's talent could determine which one gets its nose in front from a standstill, although the quality of the surface you launch from is likely to play just as much of a role. Make no mistake, though - both SRT Hellcats are extremely quick.

Engine and Transmission
A supercharged HEMI 6.2-liter V8 engine does duty in both SRT Hellcat-badged Challengers but in different states of tune. In the regular SRT Hellcat, peak outputs are 717 hp and 656 lb-ft of torque, paired with either a six-speed manual transmission or an eight-speed TorqueFlite automatic. The SRT Hellcat Redeye has outputs of 797 hp / 707 lb-ft and is also only available with an eight-speed automatic; The Black Ghost special edition adds another 10 hp is added to the Redeye, for a total of 807 hp (torque remains unchanged).
A spine-tingling supercharger whine accompanies aggressive use of the loud pedal and it's punctuated by savage acceleration. While traction can be an issue off the line, there's nothing stopping the SRT Hellcat once it's on the move - overtaking power is extreme. The manual model is obviously more involving, but choose the automatic for the quickest sprint times. It'll fade into the background at a cruise, but stabbing the throttle will see the auto 'box quickly shift into a lower gear and push you back into your seat as the V8 howls. It's senseless but absolutely addictive fun.

2023 Challenger SRT Hellcat Gas Mileage
Driven with restraint on the highway, the SRT Hellcat returns an acceptable 22 mpg when equipped with the automatic transmission. However, it's more likely that most owners will be making use of the available power more often, so the EPA's figures of 13/22/16 mpg on the city/highway/combined cycles are more realistic. The manual variant has a slightly inferior highway figure of 21 mpg. The least fuel-efficient version is the Widebody in automatic guise, which is estimated to return 13/21/15 mpg. With an 18.5-gallon gas tank, expect to get a combined cruising range of just under 300 miles from every model except the Widebody automatic, which should manage about 277 miles. A gas guzzler tax of $1,700 applies to regular SRT Hellcats and this increases to $2,100 on the Widebody models.
