The Bf 109 E-4 is a German fighter. It was introduced in Update 1.53 "Firestorm". The differences from its predecessor are little in quantity, though they have a drastic effect in-game. The E-4 is slightly heavier, but thanks to better surface polishing and a +150 hp WEP, it is faster than the E-3. The greatest advantage though is the installation of MG FF/M cannons with minengeschoße.

After having played both the E-1 and E-3, players will rejoice upon unlocking the E-4. While essentially the same plane, the E-4 overcomes the inadequate MG FF with MG FF/M, featuring the fantastic minengeschoße. With two wing-mounted MG FF/Ms with 60 rounds each, the plane has an even more deadly punch, attributed solely to the new thin-walled 20 mm HE shells. Fighting in the E-4 is essentially the same as with all E-frame 109s.

Remaining a great energy fighter against its historical opposition, the E-4 is somewhat troubled by the fact that it often faces mid-to-later-war planes such as the P-47D. To engage these, make sure you have a clear energy advantage; if attacked, fly defensively and attempt to bleed the enemy's speed while pulling them down. The Bf 109 E-4 is often regarded as a poor turner, a reputation coming from the fact that its main rival, the Spitfire, simply did it better. However, with combat flaps, the E-4 is a respectable turner able to out-turn most planes that outperform it in other ways. However, keep in mind that one of the changes from E-3 to E-4 increased the frame's weight. Flat turning should only be reserved for extreme situations.
