When this slice of solid gold Eighties Americana was unleashed onto an unsuspecting world back in 1987, it was rumoured to produce more than its quoted 245bhp.

Today, this slice of solid gold Eighties Americana has been unleashed yet again onto a very-unsuspecting world with a very definite… 1,246bhp. And that’s on the more sensible of its tunes.

Welcome, ‘INVADR’, and welcome back, brothers Jim and Mike Ring. We’ve missed you.

No doubt our American friends have missed the Buick Grand National, too. An inexplicably cool version of the inexplicably boring Buick Regal, first launched in 1982, which in 1987 offered a 3.8-litre turbo V6 beneath that boxy bodywork.

Ringbrothers has decided the old lug needed a renaissance via the medium of a carefully installed rocket into its behind. “This car is all about presence,” said Mike Ring of this '87 car. “The bodywork is subtle at a glance, but the ferocity of what’s under the hood begins to materialise on second viewing. And then you drive it.

“The acceleration of this car is nothing short of violent. This may well be the fastest car we’ve built to date.” Anyone familiar with what Ringbrothers has built to date will understand what that means.

In this car, it means a fully rebuilt, Duttweiler Performance 3.8-litre V6 engine, with a pair of ‘Precision’ 62mm turbos bolted on, delivering 32lbs of boost into a custom, hand-ported aluminium cylinder head, delivered to a billet crank.

There’s a bespoke intake manifold, an all-aluminium block, and a six-speed manual transmission doing its very best to hold on. Underneath sits a custom Roadster Shop chassis, housing three-way adjustable Penske dampers, massive six-pot Brembos and ceramic discs, and a carbon fibre driveshaft. Standard.

Though, while the body looks fairly standard, it too has been subject to some tweakery, like a custom bonnet scoop, stainless steel bumpers with aluminium guards replacing the standard plastic items, and reprofiled arches to match. There’s a custom-built chin spoiler, a new decklid spoiler, carbon fibre mirrors, a custom lower rear valance and – naturally – a bespoke exhaust system.

It's been finished in ‘Dark Vader Gray’, features three-piece 19/20in HRE wheels, and a fully restored interior with “period correct” design cues, hand-fabricated seats, digital instruments and even a carbon fibre steering wheel.

Which you’ll very much need to hold on tightly too. As mentioned, it gets a whopping 1,246bhp in its current tune, but that’s been dialled down to allow for ‘daily driving’. It’s actually capable of handling 2,000bhp when those turbos have been spooled up to 50lbs of boost pressure. Any more boost and you’d go back in time. To 1987, no doubt.

“INVADR is one of those cars we’ll remember building for a long time,” said Jim Ring. “It’s a combination of state-of-the-art fabrication and imagination plus the Grand National’s DNA, culminating in an incredible final product.”

Is this the coolest Ringbrothers machine yet?
