The Cerbera marks the point in history at which things got rather serious at TVR. This, after all, was the company's first car to feature not just a home-grown chassis and interior, but also a home-grown engine.

And quite some motor is was too. It had eight cylinders in a vee but with a flat plane crank, just like that of a Ferrari V8, and an appropriately spine-chilling soundtrack.

To begin with the V8 was a 4.2, but it was soon stretched to 4.5-litres. Not that this mattered much when it came to horsepower - in whatever guise, the Cerbera always had plenty.

I'll never forget the first road test example that came in the direction of Autocar. Within 12 hours of its arrival it had deposited its rear screen - whole - onto the M4 at 85mph. Yet even this was not enough to put some of us off. Rear screen or no rear screen, the car was so explosively rapid that no one on the magazine could quite believe it had 'only' 350bhp.

So we took it to a rolling road, just to make sure. At 445bhp and rising the car nearly jumped off the rollers, soon after which a call went in to TVR asking for a more representative example to be delivered. Blackpool flatly denied that the car had a special engine and asked us to re-test it on another rolling road. Which we did later that afternoon. The numbers said 350bhp and 320lb ft, bang on the money in other words. We never bothered to go back to the first place to tell them that their kit was out of whack.
