The Audi RS3 would be the natural competitor against the Mercedes-AMG A45 S in a drag race, but this video places the AMG in an unequaled challenge against a slightly adjusted Audi RS4 Avant. The results are fascinating.
This RS4 Avant comes from Milltek and incorporates the company’s turbo exhaust. This pre-updated model contains a 2.9-liter twin-turbo V6 developing 450 horsepower (331 kilowatts) and 443 foot-pounds (600 Newton meters) of factory torque. Presumably, the aftermarket exhaust releases a little extra power.
The A45 S is original, which means that its 2.0-liter four-cylinder turbocharged engine develops 416 hp (310 kW) and 369 lb-ft (500 Nm). Like the RS4, the Mercedes uses an all-wheel drive configuration.
With the numbers out of the way, the race can begin. The first race is with both vehicles in their automatic mode. The RS4 driver seems to skip the start, but that doesn’t matter. The A45 S is just leaving and the Audi has no chance.
Then there is a race where the Audi gets an appropriate launch. Unfortunately, a better start does not help the Four Rings wagon much. It takes longer this time, but the Mercedes finally takes the lead.

Finally, there is a race from a roller, which should level the playing field as it eliminates the advantage of launch control systems. However, the A45 S still advances at the end of the strip.
The performance of the Mercedes hot hatch is impressive considering that the A45 has less power and less torque than the Audi. The model really exceeds its weight by beating the RS4 Avant.
