Cosworth Impreza STi CS400












The Cosworth Impreza STi CS400 is the product of a comprehensive Cosworth engineering program, boasting supreme levels of pace that put it on a par with some the world’s greatest performance cars.


The launch of the CS400 provides a powerful demonstration of Cosworth’s engineering expertise in the automotive sector – one of four major areas of activity for the business in 2010 alongside the defense, clean energy generation and sports industries.

The CS400 sports an engine upgrade which produces 33% more power than the standard STi model, enabling this 4 seat family car to go from 0-62mph in just 3.7s. This searing pace is more than a match for some of the world’s most revered sports cars, including the Lamborghini Gallardo LP560 and Porsche 911 GT3.

Rather than concentrating solely on delivering more power, the CS400 has been engineered to deliver the full performance experience, featuring custom brake components developed in partnership with AP Racing and a modified suspension and handling package. In creating “The Ultimate Impreza” Cosworth has ensured that the CS400 employs simple, efficient enhancements in order to remain and as close as possible to the original design to guarantee reliability and easy maintenance at regular Subaru dealerships.
