This is a list of things that I would like to see added to the game, I know some of the vehicles already exist as mods, but I want to see how the developers put their spin on them. Above All: Custom engine sounds for all the official vehicles!!! Vehicles: A better, big block muscle car, something like a 1970 Dodge Charger A modern muscle car, maybe something like the new Dodge Challenger, as long as it looks cool, and has a lot of horsepower and torque. A bigger pickup, something with more power, something new or something older would be cool, but nothing modeled after a Ford... A German style sports car, available as a coupe and sedan, something expensive. A minivan, just because. A modern SUV, maybe two, a family vehicle, and a dedicated offroader, maybe modeled after a jeep. A supercar might be nice, just for the speed and look. A compact car, available in hybrid and electric A stock car, and maybe a F1 racecar Other: Add some buoyancy to the official vehicles to make them have a more realistic impact when they hit water, also add buoyancy to the tires to make it so you can hydroplane if that's possible. Add realistic tire smoke, and adjust how easily cars leave rubber on the road, right now it happens way too easily. Add rain, and make dirt turn to mud when it gets wet. Consider adding an adjustable temperature and water that turns to ice and vice-versa.
The tyres are bouyant. Your other suggestions have been suggested before, except water to ice which I think would be very difficult with the terrain system torque3d uses. Vehicles have a dedicated vehicles suggestion thread, for which all of your suggestions are in already.
Engine sounds are coming sometime. They were hiring sound designers a few months back, and I doubt those sound people will work on making new cars.
Real Panther bodies never had I6s, it's a luxury fullsize so it's almost an insult to give the Grand Marshal a straight six. That said, the pickup's I6 needs a new model and some love...
