Mitsubishi Lancer Evolution X

Weaknesses, engine ratings and buying advice

3.0 / 5.0 · Based on 1 engine variants · How we rate

The Evo X was a break with tradition in 2008 — and the final chapter at the same time. An aluminium block instead of cast iron, a dual-clutch as well as the manual, a more civilised demeanour. To many purists a betrayal, to others the most mature, most usable Evo. Both are true.

The engine — 4B11T: Aluminium instead of cast iron, MIVEC on intake and exhaust, a timing chain instead of a belt. Technically more modern, but quieter in character than the 4G63T. It revs more willingly and builds boost faster, the power curve is more linear, less on-off. The sound is shorter, sharper, less throaty — more civilised, if we're honest. In stock trim a reliable engine, but not indestructible: piston ring failure can trigger engine damage (sev5) — rare, but expensive. More common are raised oil consumption from middling mileage and a leaking water pump. On modified cars rod bearing wear is the sword of Damocles — the alloy block forgives less than the old iron lump. Add smaller but annoying items: the fuel pressure regulator hose works loose, the fuel pump relay fails, spark plug ceramic chips off. Know these and you'll drive relaxed.

The eternal debate — SST vs 5MT: Opinions split here. The SST dual-clutch is lightning fast and makes the X brutally effective on track — but it's the car's biggest money pit. The clutch pack and seals (3000–8000 EUR!) and the torque damper (also 3000–8000 EUR) are no trifle, and a temperamental TC-SST ECU can pile on top (500–2000 EUR). Mandatory: regular SST oil changes in the service book — if it's missing, walk away. The 5-speed manual (RS/GSR-MT) is the more honest, cheaper choice: only synchro wear (1200–3000 EUR), otherwise robust. If you want to feel the car, take the manual. If you want the fastest lap, the SST — with reserves set aside for the clutch.

S-AWC and the AYC pump: The X keeps the active all-wheel-drive system too — and with it the AYC/ACD hydraulic pump as a weak point (sev5/prob4!). It fails earlier than on the VII-IX, from around 80,000 km, and costs 800–2500 EUR. On top are the rear differential pins with lubrication failure (1500–4000 EUR) — rare, but expensive when it hits. Test drive: take every S-AWC warning light seriously.

Whole car: The factory paint is thin and extremely chip-prone (prob5!) — front ends and sills are often peppered, a respray runs 300–2500 EUR. The underbody and rear suspension corrode (200–1500 EUR), the suspension bushings wear (200–600 EUR). The stock Panasonic battery is short-lived (80–250 EUR) — no drama. There's a recall on the clutch master cylinder (NHTSA 13V446) — check it was done.

Test-drive checklist: SST service history (oil changes!), smooth take-up and shifts on the SST, S-AWC with no warning lights, paint for chips and respray, cold start without rattle, oil level and consumption documented. On the SST do a hard drive with on/off throttle — a tired clutch pack gives itself away.

Market 2026: Good Evo X sit at 25,000–45,000 EUR, Final Editions and low-mileage cars well above. Insider pick: a GSR with the 5-speed manual, full service history and a healthy AYC pump — cheaper to run than the SST and, long-term, the more carefree Evo X.

Engine Overview

The Mitsubishi Lancer Evolution X is available with one engine variant at 295 hp.

Lancer Evolution · Petrol· 295–440 PS
2008 2015

Aluminium instead of cast iron, MIVEC on both intake and exhaust, timing chain instead of belt — the 4B11T is technically more modern but quieter in character than its predecessor. It revs more willingly and builds boost faster; the power curve is more linear, less on-off than the 4G63T. The sound is shorter, sharper, less guttural — more civilised, if honest. In standard trim a reliable engine: 200,000 km without drama if the oil is changed every 5,000 km. The Achilles heel is the open-deck design — above 350–400 hp without a closed-deck insert you risk cracks between the cylinders. No issue for road use up to 300 hp. Critical in everyday use: never shut down immediately after sustained full-throttle driving — the turbo bearings will coke (replacement: 1,200–3,500 EUR). The black fuel pump relay fails from the factory — Mitsubishi released a revised blue replacement; check on every used example. First question when buying: gearbox. The TC-SST is a completely different car from the 5-speed MR — in maintenance requirements, driving feel, and long-term cost.

  • !! Piston ring failure and engine damage from 120,000 km

    Piston rings wear prematurely at high power output and elevated boost pressure. Open-deck design promotes thermal stress on cylinder bores. Above 350 hp without a deck insert this becomes critical.

    Symptoms: Heavy oil consumption, blue exhaust smoke under full load, compression loss, uneven idle
    2,500–6,000 $
  • !! Timing chain elongation from 150,000 km

    The timing chain stretches with poor oil maintenance — Mitsubishi blames dirty oil as the main cause. Early 2008–2010 models worst affected; a revised chain with fewer links arrived in 2011 but remains prone to stretch. A skipped tooth risks valve-to-piston contact.

    Symptoms: Rattle on cold start from the front of the engine, triangle warning light with rough idle (chain jumped a tooth), P0012 fault code, bent valves in severe cases
    800–2,000 $
  • !! Rod bearing wear in modified use from 120,000 km

    Connecting rod bearings wear prematurely with elevated boost pressure and low oil conditions. Especially critical with the stock oil pump at tuned output above 350 hp. Engine failure possible within a few thousand km.

    Symptoms: Metallic knocking from the engine block, rising engine noise under load, oil pressure warning light, metal particles in oil
    2,500–6,000 $

Vehicle Weaknesses

WeaknessCost
SST dual-clutch gearbox: seals and clutch pack

TC-SST seals and clutch packs wear under spirited use. The mechatronics unit is vulnerable — full repair at a specialist workshop (Teske, Gassner) runs €6,000–8,000.

Symptoms: Juddering on pull-away, rough idle, shift hesitation, SST fault message on the display, vibrations at standstill
from 100,000 km
High
TC-SST torsional damper wear

Torsional dampers in the TC-SST wear and produce noise at idle and on pull-away. Clutch Relearn (Teach-In) is mandatory after every clutch replacement — skipping it causes exactly these judder symptoms.

Symptoms: Clatter or rattle at idle, rough idle, vibrations on pull-away, noticeable shift hesitation
from 100,000 km
High
AYC/ACD hydraulic pump S-AWC failure

The hydraulic pump of the S-AWC system corrodes internally and loses pressure. This leads to traction loss and MIL illumination. Mitsubishi extended the warranty to 10 years/160,000 km on original vehicles.

Symptoms: S-AWC warning light, Service Required message, noticeable traction loss in corners, system alert on startup
from 80,000 km
High
Rear differential pin lubrication failure

Differential pins in the rear axle assembly can fail due to inadequate lubrication. Simply replacing the pins does not provide a lasting fix — specialist firms recommend a complete overhaul.

Symptoms: Clunking or grinding noises from the rear during cornering, vibration when accelerating, four-wheel-drive warning light
from 120,000 km
High
!5-speed manual (RS/GSR-MT): synchro wear

The manual Evo X variants (RS, GSR-MT) inherit the weak synchros of the Evo manual gearboxes. 2nd and 3rd gear in particular crunch with mileage and under load. On tuned cars the wear accelerates noticeably.

Symptoms: Crunch on upshifts into 2nd/3rd, notchy engagement especially cold, occasional baulking on fast shifts.

Which Mitsubishi Lancer Evolution X engine is the most fun? +
The {code} ({displacement}) offers the most driving fun in the Mitsubishi Lancer Evolution X — rated: "Legendary!". {description} 440 hp, available only as SST-MR — no manual option.
