This is the third boss in the story and you'll get this achievement simply from progressing. The bosses come in the same form of gameplay as the cop-chasing missions, except you don't need to worry about score at all, making them actually easier. Make sure while playing through the story that you buy as few upgrades as necessary for your car and save up to buy the most expensive car from the next episode's set. This is because the less expensive cars are usually not "powerful" enough to fight the bosses, even when fully upgraded, so its best to save up for the most expensive one the first time to prevent the need to grind money.
