Irmscher, renowned for its mods to Vauxhalls and Opels, stepped out of its comfort zone with the Inspiro, a striking new concept car unveiled at Geneva Motor Show in 2002. The Inspiro showcased Irmscher's creative side, blending familiar GM parts with innovative design.

Under the hood, the Inspiro was powered by a 225bhp 3.0-litre V6 engine, a familiar sight from the Omega but with an upgraded twist. The car's design was an eclectic mix of influences, resembling a hybrid between an Austin Healey and a Caterham Seven. This concept wasn't just about looks; it boasted impressive performance. With a lightweight composite body, the Inspiro accelerated from 0 to 62mph in just 5.8 seconds and could reach a top speed of 150mph.

The Inspiro’s rear-wheel-drive system, complemented by a limited-slip differential and a five-speed gearbox, ensured that all 225 horsepower was effectively delivered to the road. The car's 19-inch wheels and performance tires further enhanced its driving dynamics.

Measuring 3705 mm in length, 1775 mm in width, and 1110 mm in height, the Inspiro kept things compact and agile, weighing in at just 780 kg. This combination of low weight, high power, and distinctive styling made the Inspiro a concept car that stood out for both its bold design and exhilarating performance.
