How to unlock the Hypersonic achievement in Mafia II - Definitive Guide
For the first part of the mission you follow the guy on foot, then in a car. When you get to the place where he stops, kill all the enemies then grab his car, a Delizia Grandeamerica. Go to the safe zone to finish the mission.
Now for the actual achievement. First and foremost, upgrade the car to level 3. Next you'll have to start a mission so you can actually gain points - I would suggest one close to the highway, like Wheels of Evidence. As a bonus, if you die/screw up the car, you'll go back to the checkpoint right before starting the mission so you can quickly try again.
Once this is done, head to the start of the highway close to the big bridge and start driving down the long straight road along the river. Now it's a simple matter of gunning it, go as fast as you can and stay in the middle of the road (you can honk the horn to get cars out of your way). You may have to go around the first turn but just slow down a little bit and you should be fine.
You should get 2000 points during this corner, after that slow down to stop and when the points register you'll get the achievement.
You will have to attempt this while a scored mission is active in order to start accruing velocity points. Make sure that you have a fast car, preferably with a supercharger. If you've gotten the mission "Bet On That", the bookie drives a Delizia Grandeamerica you can steal at the end of the mission. New to Joe's Adventures, it has a top speed of 169 mph before adding any tuning upgrades thus making it the fastest non-premium DLC car I've seen so far. Start at the offramp at the east end of the Grand Upper Bridge and follow the long straightaway that leads to the freeway. The faster you go, the faster you'll gain points. Try not to hit anything but as long as you don't slow down below 70 mph, you'll continue to gain points. Just like with Cruise Control, you can honk your horn to cause most traffic to pull out of your way. Obviously this will not work for police cars. The only tricky part is manoeuvring around the turn at the end of the straightaway where you can't see the traffic you're coming up on but after that you should be fine. Avoid impacts and you'll gain 2000 points easily by the end of the route shown, and the trophy will be yours.
during the mission “Place your bets”, after dealing with the bookmaker and his goons, he took the car in which he arrived there, Delizia Grande America (only met in this mission). Its characteristics are simply killer + all three upgrades are a demon 8) Alas, the car is less controllable at high speeds, but it reaches 100 mph in 6-7 seconds. We start the Highway racing mission and drive it to 4 checkpoints. And then... it's a matter of seconds!) 1700 scored up to 5 checkpoints.
2 - Take the task “Bomb under the seat” (it is closest to the desired road, and if it doesn’t work out, it will be faster to repeat).
3 - we go onto a straight road (along the coast, from north to south) and drive.
On the Delizia Grande America - 2000 it runs up after a turn where you just have to not get killed.
In other words, you need to drive in a straight line and that’s it.
