Clearing out unnecessary rubbish
Yes, today I'll teach you how to take out trash. From your car. Bear in mind this guide goes from practical to simply insane. Continue at your own risk.
The reason I'm doing this is because, for each extra weight, the engine have to use more power to pull the car. This is best felt if the car is front wheel drive, as the car feels like it was struggling to go. Less weight means the engine doesn't have to work that hard, that means you're improving car response, acceleration and braking performance, and fuel economy.
And this is what we want the car to end up looking like, if we're super anti-social:
Lets begin the spring cleaning!
Car audio system and other entertainment crap? OUT! (saves 5KG-50KG, if your system looks like above)
Air-cond system? OUT!(Saves engine power and 10KG altogether)
Babies? OUT!( You'll save 1-2Kg here)
Family or Friends? OUT!(Save 60-200kg)
Spare tyre? OUT!(Save 1-5kg)
Portable toolbox? OUT!(Save 500g to 1KG)
Standard seats? OUT! (Saves 5-10KG)
Carpets and interior linings, plastic, all the crap? OUT! (Save around 50KG)
Standard metal hood? OUT!(Saves 3-5KG)
Carbon-Fibre hood? IN!(Weight almost O.OKG)
Racing seat? IN! (Doesn't weight alot, and might make you more popular with the girls)
Carbon fibre roof? IN!(Same reason as carbon fibre hood)
I think we've established that, there's no end or how extreme you can be to throw/remove stuff to save weight. I hope this idea can get to you. Thanks for reading.
