Among the many, many sets of wheels we're looking forward to seeing at Pebble Beach this year will be the SSC Tuatara – an all-American hypercar a long time in the making. And judging from the engine alone, it looks like it'll be quite the beast.

As well it should be, considering how long Jarod Shelby and his team in West Richland, Washington, have been working on the thing – and what they've done before. Shelby SuperCars first showed the Tuatara back in 2011, building on their experience with the record-breaking Ultimate Aero.

There's been little more than radio silence in the seven years since. But just the other day, SSC North America (as the company is now officially known) announced it was bringing the Tuatara to Monterey with the promise that it would reveal new production details.

To keep us on our toes, it has now released a handful of images and a video showing the engine that's set to power the exotic hypercar. It's kept mum in the meantime on specifications, but it promises "superior horsepower and engine characteristics" that will "far exceed what the engineering team originally set out to achieve."

The original concept called for a 6.9-liter twin-turbo V8 producing 1,350 horsepower and 1,280 lb-ft of torque. While we can't tell the displacement on sight alone, we do appear to be looking at two turbochargers and eight cylinders. But the output (and possibly displacement) look poised to surpass the concept's engineering brief and deliver "unprecedented performance." We're expecting to see further teaser videos on the vehicle's "unmatched aerodynamics" and "track-level handling" capabilities as well, so watch this space.
