The E46 realized a nearly 100-hp boost over the previous model, thanks to a new stronger iron block capable of a higher RPM redline. Well over 300 ponies reside under the hood and the iconic straight-six can rocket to a ceiling of 8,000 RPM. This is the first M3 that will really wag its tail given a heavy foot when exiting a turn. That can be a good thing, and it by no means means the car’s cornering ability is diminished; it just means there is a lot of juice lurking under that bulging hood. Taking a look around the E46 you will notice the wider flared fenders that nod to the E30 and accommodates the wider stance of the M3 compared to the 3-series. Sure it’s the largest M3 to date – which may have some questioning the philosophy of its build. Take a seat and put your foot down, however, and it will all become clear that the E46 is nothing but pure M.
