The M6, weighing 4244 lb (1925 kg), has a slow rate of acceleration, despite its mid-high nitro stat. Due to its weight, the M6's handling is subpar. The M6 interestingly gains the same amount of speed with the top speed maxed out as when the nitro is upgraded, although the M6 appears to be more nitro-focused. The M6 has decent nitro efficiency, at 6/12/16. All this for 175,000 credits.
