There’s a well-worn automotive axiom that plays out many different ways: The amount of money you spend is proportional to how fast you go. You want more speed? You spend more money.
If you’ve priced a BMW M3 these days, you see the principle at work. Back in the old days (1987), a U.S.-spec M3 boasted a 195-horsepower four-cylinder engine and did 0-60 miles per hour in about 6.7 seconds on its leisurely way to a 143-mph top speed – all for just over $30,000.
Today, the least expensive 414-horsepower V8 M3 will set you back $58,400. As it should, the new M3 trounces the old in every conceivable performance metric with its 4.6-second 0-60 mph run, supercar mid-range and electronically-limited 155-mph top end.
This reality left enthusiasts wishing BMW would offer something a little less speedy for a commensurate drop in MSRP. Seeing the opportunity with its 2012 1 Series Coupe, BMW will soon show us how much speed around $45,000 will buy at the upcoming Detroit Auto Show. But to tide you over until then, come with us for a ride in a BMW 1 Series M Coupe prototype.
