Opel is celebrating the 100th anniversary of the Grand Prix de Lyon by announcing plans to return there with three cars that competed in the race a century ago.

Originally driven by Carl Jörns, Emil Erndtmann and Franz Breckheimer, the Grand Prix cars were far removed from today's racers as they featured an unsynchronized four-speed transmission and hand-activated rear brakes. The drivers were assisted by "riding mechanics" who were tasked with monitoring gauges, manually increasing the fuel pressure (with a hand crank) and working on the car during pit stops and break downs. While the cars aren't high-tech by today's standards, they were able to hit speeds of up to 160 km/h (99 mph).

Besides the three original race cars, Opel will display the 1914 "Green Monster” which has 12.3-liter engine that produces 260 PS (191 kW) and 700 Nm (516 lb-ft) of torque.
