With two amazing cars that carry virtually the same price tag, the comparison must come down to factors other than price. That makes your choice between the two much more difficult, but also more fun to accomplish. When you don’t have a brand loyalty that stands in your way of choosing one or the other of these two awesome cars, the choice and selection may take some time to finish, but possibly seeing this comparison will help you to make the right choice between two sports sedans.
Starting with the RS 7, the car is powered by a 4.0-liter twin-turbocharged V8 engine that requires premium gasoline to operate (most luxury cars do). The power inside shows up at 560 horsepower and 516 lb.-ft. of torque and gives owners a 16 city/27 hwy mpg of fuel efficiency to enjoy. As transmissions go, the RS 7 is equipped with an eight-speed automatic that smoothly shifts through the gears. As for looks, the RS 7 is mean looking up front with the angled headlights and low front ports as well as having an athletic and wide stance on the road that lets anyone know this car is ready to roll wherever you need it to.
On to the CLS-Class which, for the purpose of this comparison, is the S63 AMG model. This car is powered by a 5.5-liter twin turbo V8 engine that operates on premium gasoline as well. The CLS will bring in a strong 577 horsepower and 590 lb.-ft. of torque for only $50 more than the RS 7. As for fuel mileage the CLS shows up with 16 city/22 hwy mpg, which is a huge difference from the RS 7. The transmission offered is a seven-speed automatic that is highly engineered to perform perfectly on any road. The highly recognizable three-point star emblem shows up on the front of the CLS and this car is seriously gorgeous with an interesting angle or look from each and every location of the vehicle.
For other equipment, the two are comparably equipped with all-wheel drive systems and warranties that are identical. The choice with the statistics given will have to come down to power or fuel mileage. Unless you plan on keeping your luxury car cooped up in city driving, in which case you really don’t need the power offered anyway, you will be heading out on the highway often and the difference between the power and fuel mileage can be a difficult choice.
As the decision boils down to power or fuel mileage, the number as seen above are a comparison of 22 mpg on the highway for the CLS versus 27 mpg for the RS7. The power is not hugely different in the horsepower realm but the torque is a major difference with 516 for the RS 7 and 590 for the CLS. With this being the actual deciding factor, power or fuel mileage, whatever your priority may be for your luxury sports sedan.
