HBH (Denmark) - AllCarIndex

HBH (Hermann Brandt Hartvig) was a Danish automotive design and engineering consultancy, active in the early 2010s. Founded by Torben Hartvig, Christian Brandt, and Jesper Hermann, all of whom had previously worked on the Zenvo ST1 supercar, the firm specialised in concept design, engineering, business development, and investment strategies for automotive projects.

In 2011 HBH announced the Bulldog GT, a one-off supercar based on the Aston Martin V12 Vantage. The car featured hand-beaten aluminium bodywork inspired by Aston Martin tradition, a twin-supercharged 5.9-litre V12 producing 675 PS, and a six-speed manual transaxle. Claimed performance included 0–62 mph in 3.9 seconds and a top speed of 300 km/h. Carbon-ceramic brakes, forged alloy wheels, and bespoke aerodynamics were also part of the specification. Originally conceived as a unique commission granting the client partial design and production rights, the project was also promoted as a potential small-series venture.

HBH positioned the Bulldog GT as an opportunity to merge supercar engineering with exclusive craftsmanship, but there is no record that the project advanced beyond the prototype stage.
