2014 Aston Martin Vanquish

As far as unexpected encounters with wild animals go, squirrels don't normally rate. The furry little nut-smugglers are omnipresent fixtures in my neck of the woods – literally – so normally a chance meeting doesn't warrant caution the way a bear or even an ornery raccoon might. But one's list of priorities can't help but change a bit at 175 miles per hour. That was exactly the case when I drove this Aston Martin's predecessor, the DBS, a few years ago.

I was hammering around a closed course – Ford's Romeo proving grounds – on the company's high-banked track, 25 mph shy of the double ton, when a little red dot appeared on the surface of the track, far up the straight. It was a squirrel, which, lacking the good sense not to be on the track at that particular moment, was at least smart enough to flatten itself into a pancake (perhaps it heard the Aston's mighty V12 closing in). I prayed it wouldn't dart from its adjacent lane into mine, because at my closing speed, I figured I wouldn't have time to retaliate. Naturally, the kamikaze rodent skittered on its stomach directly into my trajectory at the last minute, leaving me no choice but to issue a critical hair's breadth correction at the wheel. Roadkill manufacturing is normally a momentary wince-inducing affair – a grimace, a quick appeal for the universe's forgiveness – and then on with one's day. Yet in a car as low as an Aston Martin, at the velocity I was traveling, a bit of fur flying and battered karma would've been the least of my concerns.

12-cylinder 'LS12' will blow your mind, doors off

So there you are on May 1 minding your own business on the internet when a forum user called "V12Baker" uploads a picture of the engine block above. But you're on the LS1 forum, a site devoted to the legendary V8s made by General Motors, and that's a V12. V12Baker explains that he sliced two LS1 engines and used the pieces to not only make an LS12, but also a V4 with the leftovers. That is probably when, like user "3.8redbird," you write "April Fools day is April 1st not May 1st."

But the engine is real, built by a guy named Ray and his partners in a shop in Seattle, WA. Ray said they wanted to make a V12 engine for a plane, and after experimenting with Buick 215 engine blocks they got around to the LS. With a stock stroke and a 4.4-inch sleeve, the result is a 545 cubic inch motor (8.9 liters) that fires like a V16 short of four cylinders. Their first two LS12 builds went into a 3/4-scale P51 Mustang, and a Chevrolet Tahoe two years ago. The Tahoe engine, only the second build, was said to get around 525 horsepower.

They now have the parts to make five more LS12s and are refining their technique, working on simpler solutions for the crankshafts - they machined the first crankshafts from a solid piece of steel, but that's crazy expensive. One of the engines is already slated to receive a massive Littlefield supercharger and "might find its way into a long-nosed 240Z." That Z, mind you, will also be getting its own chassis since the decades-old original item couldn't begin to handle the power.
