Carl Benz Center, Event centre in Bad Cannstatt, Stuttgart, Germany

The Carl Benz Center, known until 2026 by that name and now called Wolff & Müller Energy Center, is an event centre opened in 2007 in the Neckarpark in Bad Cannstatt, Stuttgart. It stands between the Porsche-Arena and the MHPArena and offers around 20,000 square metres of floor space. Its main hall, the Wolff & Müller Forum, covers about 1,500 square metres and holds up to 2,000 people; the complex also contains a 150-bed Hilton Garden Inn hotel and VfB Stuttgart facilities, including a 900-square-metre artificial-turf pitch on the roof.

The building stems from a joint idea of investor Rudi Häussler and VfB Stuttgart. In 2005 the Stuttgart municipal council approved it on condition that the exterior be finished before the 2006 FIFA World Cup, which was met. A water ingress postponed the planned opening of 5 October 2006; the center was finally inaugurated on 16 May 2007. It carried the name Carl Benz Center until 2026, when naming rights passed to the construction firm Wolff & Müller.

The name honoured Carl Benz until 2026, when naming rights passed to the construction firm Wolff & Müller. On VfB Stuttgart home matchdays the centre serves as a gathering point for fans, with a service centre, fan shop, ticketing and club premises inside. A sports bar with beer garden and a rooftop artificial pitch belong to the complex.

The center sits between the Porsche-Arena and the MHPArena in the Neckarpark, served by the U19 Stadtbahn stop "Neckarpark (Stadion)", also reached by U11 on event days, and the S-Bahn stop "Neckarpark (Mercedes-Benz)" within walking distance. Drivers use the B10 and B14; 300 parking spaces are directly adjacent and around 10,000 more lie nearby. The outdoor areas and the green plateau can host open-air events.

The VfB Stuttgart keeps a 900-square-metre artificial-turf pitch on the roof of the building, used by its youth academy. On match days the centre serves as a meeting point for fans, with a service centre, fan shop, ticketing desk and rooms for fan clubs.
