Industrias Lahoz is located in Golmes (Lleida-Spain) and it specialises in the design and construction of racing cars for AutoCross and Hillclimbing that are sold under the commercial name of Speedcar.

Currently, Industrias Lahoz produces the Speedcar Xtrem and TTX (for the CarCross and Division Three categories of AutoCross) and the Speedcar GTR (for the CM group in hillclimbs). With these models, as well as with the previous ones, the Speed Car 1 and 2 for Autocross and the GT100 for hillclimbing, Industrias Lahoz has achieved a lot of wins at both national and regional level, with several titles in the Spanish Autocross Championship (since 1998) and the CM Cup of the Spanish Hillclimb Championship (since 2004).

All the Speedcar models have been wholly designed and built in the facilities of Industrias Lahoz, and their success, both sporting and commercial, is shown by the very considerable number of Speed Cars racing around the world, with Lahoz products being usually present in any autocross or hillclimb national or regional event.
