The Mercedes-Benz CLS 550 is the most powerful option here and also quite pricey too. It delivers a breathtaking 402 horsepower along with 443 lb-ft of torque. The result is an overwhelming 4.9-second time for 0-60mph sprint and a 13.7-second time for the standing quarter-mile sprint. It has a slightly higher top speed of 159 mph as compared to the 155 mph top speed of the rivals. The BMW 640i gets a 3.0-liter turbocharged I6 motor, a classy BMW touch, and delivers 335 horsepower along with 332 lb-ft of torque. Albeit the mediocre power and torque figures on paper, its performance levels are at par with the A7. The Porsche Panamera is the least powerful option here with a 3.0-liter turbocharged V6 under its hood. Owing to the sporty setup of the car, it manages to stay at par with the more powerful opponents here on the list.
How well does the Audi A7 handle?
Ride and handling are two of the strengths of the Audi A7 and it nails the handling part almost perfectly. Throw the car around the corners and it absolutely hugs the tarmac tightly while the Quattro system does its magic under the car. Switching to the sportiest setting of the car, the response from the motor increases and the steering wheel weighs up nicely along with the suspension system getting firmer, to offer the best possible handling characteristics from the car. The ride quality is pliant and the car soaks up tarmac undulations and small speed breakers quite easily.
Braking performance
Being a luxury car that is also a wee bit focused on performance, the 2018 Audi A7 gets some impressive braking hardware underneath. The ventilated 14-inch front rotors and the 13-inch rear rotors do an excellent job of keeping this powerhouse of a car under control and the braking distance is equally impressive at 109 ft., matching up with some of the sportscars out there.

The Mercedes-Benz CLS 550 impresses yet again. It has the biggest front brake rotors at 14.2 inches yet the smallest rear brake rotors of 12.6 inches. Together, they halt the car to a dead stop from 60mph within 104 ft, the shortest distance covered in comparison to the rivals here. The BMW 640i has the smallest front brake rotors here yet its impressive stopping distance of 106 ft might take you by surprise. The Porsche Panamera disappoints slightly with its rather long 113 ft pf stopping distance.
