"If you are cruising at light load at highway speeds, 60 mph+, you should be easily able to engage MDS. There is not an active indicator in the EVIC of the Challenger. Cruising on the highway, I can easily beat label fuel economy with this driveline. The new 5.7 developes more torque in MDS and can easily pull road load at speed. 2018 Dodge Challenger SRT Hellcat. 2018 Dodge Challenger SRT Hellcat 6.2L V8 GAS Automatic 8 Speed Added Mar 2018 • 203 Fuel-ups.

Range on a tank and refueling costs assume 100% of fuel in tank will be used before Dodge offers four different engines for the 2017 Challenger, starting with the base 3.6-liter V6. This 305-horsepower engine (268 pound-feet of torque) delivers a respectable mix of power and fuel economy, with a rating of 19 mpg in the city and 30 mpg on the highway. That's average for a muscle car.

Range on a tank and refueling costs assume 100% of fuel in tank will be used before On average, my 2009 5.7 six-speed got maybe two to three mpg more than my 2015 6.4 six-speed. Some of that may be that I was driving just a little more aggressively with the 6.4. But even the 6.4 can achieve 29+ mph on a mostly flat highway at 55 mph if driven carefully. Recommended fuel. City consumption. Highway economy. Combined cycle. SRT8 6.1 HEMI V8. Petrol (Gasoline) 14.7 mpg (USA) 16 l/100 km. 22.2 mpg (USA) I drove a 2009 M6 5.7 and then traded it in on a 2013 M6 6.4. Overall mileage driving the same style on the same roads went down about 1.5 mpg. In terms of performance, the 6.4 is not only much faster but has far more low and midrange torque, something you notice constantly in everyday driving situations and not just WOT.
High fuel consumption without the power you want. It's kind of the biggest compromise engine for the challenger. You get better fuel efficiency than a 6.4 or 6.2 but you're missing some power. Power is still better than the 3.6. just don't own a 3.6 and you won't get clowned on
The 2015 Dodge Challenger SRT Hellcat debuts with a supercharged 6.2-liter Hemi V8 capable of an incredible 707 horsepower. EPA city/highway fuel economy: 19/30 mpg. 5.7-liter Hemi V8 372

Hal H. The M6 5.7 has more aggressive tuning / timing advance curves over the A8 (and A5 for '09 - '14) this is why the HP rating is 2 - 5hp (depending on years) and 10ft.lb. torque higher over the A5 / A8 application. In order to get the peak power the M6 / 5.7 is tuned for, you need 91 octane. The Dodge Challenger with the 5.7-liter HEMI V-8 engine offers impressive fuel efficiency for a performance vehicle. Equipped with an automatic transmission, this powerhouse delivers an EPA-estimated mileage of 16 MPG in the city and 25 MPG on the highway. Nonetheless, with 345 horsepower and 375 lb-ft of torque, the new 5.7-liter V8 was one of the most powerful mass-produced engines at the time, which also happened to deliver decent fuel economy.
