The 7G-TRONIC 7-speed automatic transmission, with its seven forward speeds, provides a larger ratio spread between the highest and the lowest gears while at the same time the ratios are also more closely spaced, to ensure optimal engine speeds at all times, reduced fuel consumption and virtually imperceptible gear changes. Multiple downshifting, which allows the 7G-TRONIC to skip gears when changing down, provides faster mid-range acceleration.
The 7G-TRONIC is standard for the E 300 BlueTEC, E 320 CDI, E 420 CDI, E 350, E 350 CGI, E 500 and E 63 AMG models and optional for the E 280 CDI, E 230 and E 280 models.
