Manhart's MH5 900E squeezes 897 hp from the BMW M5 Touring using upgraded turbos, a new exhaust, and revised software ...

The BE 6 Batman Edition was supposed to be a limited run of 300 units, and the announcement of follow-up batches has owners miffed.

Now known as the MH900E Touring, this practical beast gets a bigger and better turbo plus an upgraded downpipe and tune on top of many other enhancements.

Based on the X7 and 7 series, the models will make their first appearance at the Concorso d’Eleganza in Italy.
