A comparison of unique sorts has been set up by Fifth Gear’s Jason Plato. They have placed the Audi RS6 and the Mercedes E63 AMG bang opposite each other. The two most powerful sedans of their times have a battle at hand in this case.
For specs the Audi RS6 is fitted with a 5.0 liter V10 engine. This one delivers 580 hp and 480 ft lbs of torque. The E63 on the other hand has a 6.3 liter V8 which gives 518 hp. The Audi RS wins hands downon the power stakes and comes out the more powerful car here. However in a sprint comparison both cars make 0 to 60 mph in 4.5 seconds.
Next is the top speed where both once again are rated at 155 mph. There is however an option in case of RS6 for the top speed to be increased to 174 mph by customer request.
Choice of which is the favored one would naturally differ and for verification the video can be checked.
