In the Triumph naming system, the TR numbers indicated a new body. Not the TR8.
The ’65-67 TR4a had a four-cylinder 2.1 litre unit. The ’67-68 TR5 had a straight six 2.5 litre unit as did the TR6 which ran to 1976. Then Triumph reverted to a 2.0 litre four with the TR7. Oddly then the TR8 name served to indicate a new engine, the Rover V8 and not a new body. But it’s the disappointing ashtray that we’re here todiscuss. It’s door mounted which is an unusual touch. It looks like a horizontal lower hinged device, and singularly badly located for smoking and driving. They did that on the other side too.
