Pretty much what I said earlier All an aftermarket diesel chip does is inject more fuel. It results in quite a bit more power, but you're going to fail that MOT, especially without a cat.
Not if you mess with other things it won't pass MOT
If you're lucky it will pass with only the decat, but other mods like a chip will certainly make it fail :/
It's not like putting a turbo on it is more reasonable at all, that's not what I said LOL.
You're comparing with the 4Motion system (which is like 90% FWD biased). Additionally the cars are really weak.. And 4Motion is heavy compared to that power.
Get in cars with 250 hp+, and it's a different story. The grip advantage from a REAL, rear-biased AWD system outweighs the weight advantage in a 0-60.
Engine torque only affects acceleration in your imagination. It's all about wheel torque, which is basically determined by gearing.
Also, if you think any FWD car will start out by BEATING an AWD car..... There's no hope.
Sounds like you have no idea what it takes Get a program in which you can actually model a car. Then model a car. Then come back..
Blender is the best free choice. It's not per se a 'manufacturing' program like Solidworks, Catia or AutoCAD.
