Audi S1 Hoonitron

The S1 Hoonitron was built as an all-electric tribute to Group B rally cars, developed for a viral driving film series and finished in bold, eye-catching livery designed to look dramatic while sliding sideways through city streets. This set captures the Hoonitron’s short, stubby proportions and wide fender flares.

The Hoonitron’s design deliberately echoes classic Group B rally silhouettes while wearing a distinctly modern, graphic livery, and we’ve built that livery using contrasting brick colors along the doors and roof rather than a full sticker sheet, keeping the design crisp and durable.

Every GTblocks set is engineered from official building instructions and genuine, third-party compatible bricks, panel-gapped and finished to a standard that holds up on a shelf or in a display case. The widened fender flares and roof-mounted light bar are built as distinct, raised elements, keeping the Hoonitron’s aggressive rally-inspired stance intact. Expect the kind of parts-count and engineering integrity that makes the build itself as satisfying as the finished model.

GTblocks exists for one reason: to turn iconic cars into brick models that actually look right on a shelf. Every set ships from our own warehouse with GTblocks packaging, a numbered instruction booklet, and the same 29,90€ price across the whole range — no hidden fees, no import surprises.
