Mitsubishi Lancer Evolution X GSR (CZ4A)
The Mitsubishi Lancer Evolution X, chassis code CZ4A, represented a complete reinvention of the Evolution concept. Gone was the venerable cast-iron 4G63T, replaced by the all-aluminum 4B11T producing 291 horsepower in US specification. The new engine was lighter and featured dual MIVEC for both intake and exhaust camshafts, delivering broader power delivery than its predecessor.
The GSR trim offered two transmission choices: a traditional five-speed manual or the innovative Twin Clutch SST (Sport Shift Transmission), a dual-clutch automated manual offering lightning-fast shifts. The S-AWC (Super All Wheel Control) system integrated AYC, ACD, and stability control into a unified system that made the Evo X remarkably approachable at the limit.
Built on the larger Lancer platform, the Evo X was more refined and comfortable than previous Evolutions, sparking debate among purists who preferred the rawer character of the 4G63 cars. The styling, penned by Omer Halilhodžić, featured an aggressive shark-nose front with prominent air intakes and a more integrated rear wing.
Production continued through 2016, making it the longest-lived Evolution. The Final Edition, limited to 1,600 units worldwide, marked the end of the Evolution lineage as Mitsubishi shifted its focus to SUVs and electric vehicles. The Evo X remains a potent and practical sports sedan, offering strong aftermarket support and the last hurrah of one of the most storied names in rally history.
The Evo X is the most accessible Evolution due to longer production and wider availability. SST dual-clutch gearbox can be expensive to repair; manual is more reliable long-term. The 4B11T all-aluminum engine lacks the legendary tuning headroom of the iron 4G63 but is still very capable. Check for turbo lag and boost creep issues. S-AWC system should be inspected at specialist shops. Final Edition commands a significant premium. Rust is generally less of an issue than older Evos.
Produced from 2007 to 2016, the longest production run of any Evolution. The Final Edition (2015) was limited to 1,600 units worldwide. US-spec GSR rated at 291 hp. Last Mitsubishi to bear the Evolution name. Assembly at Mizushima plant alongside standard Lancers.
