Why a 40-year-old Datsun is the second most popular car in Forza 3

It's really no surprise that on this list of the 99 most-raced vehicles in Forza 3, the pole position goes to the Bugatti Veyron and its 1,001 virtual horsepower. Right behind it? The Datsun 510, a 40-year-old compact Japanese car. Why?

For the same reasons they're popular among classic racers — light weight and easy engine swaps. Under Forza 3's rules, a wide variety of engines can fit in the 510's engine bay, such as the older Nissan RB26DETT good for a few hundred horsepower depending on turbo boost. It can also receive any number of upgrades such as all-wheel-drive.

The result: Datsun 510s top the Forza 3 leaderboards in drag racing, and in various tunes can clip off one-mile runs in about 20 seconds — a world-record pace in the real world. YouTube is rife with videos showing the little Datsun beating Bugattis or even the Peugeot Le Mans race car.
