Re: Pollution impact
which is what I've been asking for ages. Why not retro-fit new technology in current cars?
It used to be done with LPG/LPI though I understand that replacing a whole engine and drivetrain is significantly more difficult.
But I guess there's more money to be made from totally new cars with their own new problems then allow people to keep using their current cars.
Not to mention that most o/t new e.g. hybrid cars are fugly!
