The H-Type typifies the change of direction towards the mass market taken by Vauxhall under GM’s ownership after 1925.
I had initially assumed that its innovative features were the result of leaning on GM’s expertise. In particular I thought that its pioneering unibody/monocoque design would have relied on the know-how of GM’s famous US Fisher Body division. But in fact, the H-Type predates the first US-market GM unibody (the Corvair) by about two decades. 2/2
