The Roadrunner+ brings many improvements, and upgrades to the much loved Roadrunner truck. If you're looking for a well-refined semi truck, full of attention to detail, and plenty of grunt, then this is the truck for you. With more animations than you can poke a stick at, including an animated stick!

- More powerful engine (581 kW / 790 hp, 699 kW / 950 hp, and hybrid motor assisted 950 hp diesel, delivering 1,324 kW / 1800 hp!)

- Upgraded brakes, to handle the higher power and speed

- Powerful headlights with high-beam spot lights
