The Chevrolet Series 490 (or Four-Ninety) is a Brass Era American automobile, made from 1915 to 1922. The June 1915 introduction of the $490, Chevrolet 490 was an immediate success and established the brand as a big player. The name would not denote the price for long (in 1921, the average price was $820), but it would stay low enough to take a chunk out of the Model T market. The Model T started at $495 at the time. Chevrolet was soon so profitable that Billy Durant began buying shares of GM stock with his Chevrolet stock. Electric horns were standard. And by 1921, standard equipment included a speedometer, and ammeter, dome lights (closed-body cars only), and headlight dimmers.

All 490s were only offered with the Overhead Valve 171-cubic-inch (2.8 L) four cylinder, producing 26 hp (19 kW). This would be Chevrolet's main engine until the "Stovebolt" straight six replaced it for 1929.
