Mitsubishi Lancer Evolution X FQ-440 MR is a tuned version of the lancer (like all other FQ...). The uk importer of Mitsubishi modified thes cars not the factory. This is the reason why these models were only available in uk. IMHO not a production car.
Top 50 Most powerful 4-cylinder cars 2020
Inline 4 cylinder is most popular engine layout for use in passenger cars throughout the world.
They are cheaper to produce than "V" type engines which require complex block shape and two cylinder heads and camshafts. They also require less material and moving parts then longer 5 or 6 cylinder inline engines.
Modern 4 cylinder engines with turbochargers can still produce more than enough power for any passenger vehicle requirements, even for very high performance cars.
The list compiled here includes all road-legal 4 cylinder cars (inline or "V" type), leaving out notable racecar exceptions, like the Porsche 919 LMP1 which has famously powerful V4 engine (well over 1000 PS in combination with electric motors).
This list is limited by available data and new vehicles will be added as new data arrives.
