perhabs some of you remember my first post on eb: Audi rally car. Soon after I posted it, I realised that I didn't like it enough. Therefore I decided to create a brand new version with roughly the same DNA. The main goals for the new version were to look better and drive better compared to the old one.
To improve the looks, I went for a classic collor scheme: red body and black roof. I also downsized the width (17 stud compared to 18) and the wheelbase (two studs shorter). To get some more contrast, I put blue racing stripes on the seats.
Making the car smaller meant I couldn't use some tricks used in the old one, such as BuWizz inbetween the front wheels. It is now located underneath the trim.
To improve driving, I decided to use two Buggy motors rather than one and put them as low as possible in the chassis for the best COG. The gear ratio is the same as before: 1:1. The steering is also much smoother and has almost no backlash. Due to these improvements the car drifts WAY better then the old one. It even does donuts. Here you can see some pictures of the drivetrain and rear suspension.
Due to the insane power from two buggy motors, gears often slipped during the development. A simple but effective solution I came up with was to use knop gears rather than 12t bevel gears to transfer the power to the rear wheels.
The car features, like the old one, front and rear suspension, but it is a very different setup. The front now uses traditional suspension arms and the rear is a liveaxle without diff.
The doors and bonnet can be opened manually. Because there is no battery under the bonnet, there was a bit of space for a fake V6 engine made out of knop gears.

In case you think that the car is slow, that is due to the fact that I am a NOOB driver. In all the video clips BuWizz was in normal mode.
