Now its time for contemporary fuel economy gauges

To give you more e28 and e34 vibes, there are three new gauges cluster versions, that make driving in cockpit view a lot more entertaining:
- 220 km/h petrol
- 260 km/h petrol
- 220 km/h diesel



The configs are revised, so the facelift models (except base) have the new gauges with the additional econ needle

Also the burnefficiency of the 1.8 L inline-4 diesel is improved a little.
