In 1994 a 167 hp 2.5 L V6 was introduced, thus creating what many considered to be the finest Calibra to date. Available with both manual and automatic transmissions, the V6 wasn’t as fast as the Turbo, but was rather more civilised, and proved to be more reliable than the complex four-wheel drive model with its notorious transfer box issues. 1995 saw the introduction of the the X20XEV Ecotec engine, a cheaper, less reliable derivative of the classic X20XE 16-valve or "red top" engine. This marked a reduction in power from 156 bhp to 136 bhp for the 16-valve version, although the Turbo continued with the C20LET.
One of the most versatile small German military vehicles, the Kettenkrad, a blend of a tractor and a motorcycle, was powered with a 1.4 L Olympia four-cylinder engine. Produced by NSU, it had motorcycle-type front-wheel steering for gentle turns and negotiated tight corners with brakes on the propelling caterpillar tracks. The Kettenkrad towed antitank guns and transported troops and signal gear in several theatres of war. NSU continued to make it after the war for use in mines and forests. It was one of the few vehicles that could do jobs formerly performed by horses for which, owing to the shortage of oats, even less fuel was available than for motor vehicles.
As it turned out, the Opels were still lacking in this department. Manuel Reuter was fastest of the two with 5th on the grid, while Keke Rosberg clocked a disappointing 9th time. Both managed to be slower than several of the lesser Mercedes. Both races left much to be desired as well, with Rosberg finishing 7th in Race 1. Reuter retired with electronic gremlins after just 6 laps, and was forced to miss Race 2. Rosberg was felled by similar issues in Race 2, and slowed after 10 laps.
