Very few Bf-109G2 were operational in 1942.
Generally spoken, they were slower, slower climbing, had less acceleration and handling than the Bf-109F4. In 1942, the -109F4 was already cleared to 1.42 ata, while the -g2 was derated to 1.30 ata and thus had less performance. The -f4 was also the more numerous fighter variant.
Hello Vincenzo
Spitfire F Mk IX Test BF274 says that Spit F IX climbed to 6096 m in 5' 36" at Combat rating, that is backed up by a test report.
And how fast was G-2, some German reports say 650km/h, some 660km/h.

The follwoing graph is composed from all Spit FIX-tests aviable at Mike Williams site (all with radiator flap closed) and all Bf-109G1/2/4 tests aviable at Kurfürst site (Erla tests corrected for radiator flap position). It shows an average speed curve for both planes as evidenced by the aforementioned tests. Since there are more Bf-109 tests, the standart deviation is larger for that type, too (not shown here but in an older thread). At the bottomline, the Bf-109G2 could mainten it´s top speed for a longer duration (30 minutes instead of 5) but otherwise both planes are evenly matched.
As of 1 August 1942 (figures 31 August), Bf 109s with first line LW units:
Bf 109G: 215 (304)
Hello Vincenzo
now in combat situation Spit pilot would probably have used combat rating, wouldn't he.

What strikes me is the DB605 engine has a nice smooth power curve.
i found this as 1st august
