Description

The Austin Seven Grasshopper was a specialized trial car developed in the late 1930s for off-road motorsport competitions. Built as a lightweight and highly capable machine, it was designed for trial events, which required cars to navigate steep hills, muddy terrain, and challenging obstacles.

Based on the Austin Seven chassis, the Grasshopper featured a stripped-down body with minimal weight, cycle-style mudguards, and a high ground clearance to tackle rough terrain. The 747cc four-cylinder engine was tuned for better torque and low-speed performance, essential for climbing steep inclines. A close-ratio gearbox and a modified suspension system provided improved control and traction, making it highly competitive in trial competitions.

Only a limited number of Grasshoppers were produced, and many were further modified by private owners to suit their racing needs. The car’s lightweight construction and agile handling made it a favorite among enthusiasts who enjoyed off-road motorsport challenges.

Today, the Austin Seven Grasshopper is a rare and highly collectible vehicle, admired for its role in early motorsport and its enduring reputation as a capable and spirited trial car. Enthusiasts continue to preserve and compete with surviving examples, keeping its adventurous legacy alive.
