BRA / Model record
BRAQ4 Challenger
Production2003
Recorded originUnited Kingdom
ClassOpen two-seat recreational buggy
Built2 units
A deliberate departure from BRA's retro roadsters: two road-legal buggies developed from the NCF Blitz2 concept. NCF supplied a spaceframe design which BRA modified to accept the complete subframe and K-series powertrain from a 1992-on Rover Metro, along with Mini/Metro components elsewhere. Both Q4 Challengers were registered, but remained production prototypes rather than kits offered in series.

Record depth — Documented
How this is measured → This record contains useful sourced evidence, but it does not yet meet the reference-ready standard. Still needed: attributed imagery. Fields we cannot source stay empty rather than guessed.
Research notes
Exactly two registered prototypes; BRA retained both and stated there was no production plan.
