The RS500's turbocharged 2.5-liter five-cylinder engine, borrowed from the standard Focus RS, has been tuned to deliver 345 horsepower and 339 pound-feet of torque. Ford says the RS500 will sprint from zero to 60 mph in 5.4 seconds, with a top speed of 165 mph
The major upgrade is the turbocharged 2.5-liter 5-cylinder engine, which has been modified to pump out a staggering 420 horsepower, and that is 115 more horsepower than the stock Focus RS and 70 horsepower more than the RS500. Now that is mad power on this little car. We hope that this front-wheel drive car can handle that much power
