Marinha Grande · Portugal
Two models. Four homologations. One factory.
Road cars built in Marinha Grande. Race cars homologated from them. A factory squad that finds the faults before customers do.
The Marque
Engineered in Portugal to be raced, repaired, and raced again.
Vantera was founded in 2013 by a composites engineer who had spent eleven years building other people's chassis and watching them come back broken. The company tools and cures its own structures in Marinha Grande. Everything else follows from that.
Read the historyModels
Two models, four builds. The GT3 is a mid-engined homologation series of sixty. The GT4 is in continuous production. Each has a competition version homologated for a specific category, sharing part numbers with the road car wherever the regulations allow.
Motorsport
A class win at the 24 Hours of Spa before the current homologation expires in 2028.
The factory squad races so that customers do not have to discover problems on their own time. Two GT3 R in the GT World Challenge Europe Endurance Cup, a development car at the Nürburgring, and no factory entry in GT4 — that grid belongs to customer teams.

Race report
Four thousand kilometres at the Nürburgring, and one broken upright
The development GT3 R completed four Nürburgring Langstrecken-Serie rounds without a technical retirement. A left-rear upright failed on the final test day at Adenauer Forst. The revised part is already homologated and goes to customers at no charge.
Press release
SRO homologates the GT4 R Evo package for 2027
The kit revises the radiator ducting, the front splitter mounts and the damper specification. It retrofits to every chassis built since 2021 and is priced within the category's upgrade cap. Fitting takes one day in the customer's own workshop.
Race report
Fourth at Spa after a three-minute brake duct repair
The No. 42 GT3 R ran second into Sunday morning before debris damaged the left-front brake duct at 04:12. The repair cost three minutes and one position. Both factory cars finished, 511 laps between them, with no unscheduled mechanical stops.
