Bugatti has just released images and video of the beating heart that will power its new Tourbillon hypercar, and it's absolutely bonkers. This isn't just any engine; it's a naturally aspirated V16 built by Cosworth – a company that knows more about making engines scream than an opera vocal coach. But what's caught the attention of engineering nerds everywhere isn't the 16 cylinders, or even the 9,500rpm redline that makes Formula 1 cars sound like they're not trying hard enough. No, it's the timing system – a bizarre Frankenstein creation that combines chains and gears in a way that's never been seen before in an automotive engine.This is the automotive equivalent of finding out that Picasso and Leonardo da Vinci collaborated on a painting using both oil and watercolors on the same canvas. It simply shouldn't exist, and yet here it is, beautifully machined in metal, ready to power what will undoubtedly be one of the maddest cars ever created. A Tale Of Two Timing Chains: The Most Complex Solution To A Problem We Didn't Know Existed Looking at the front of this mechanical masterpiece is like peering into the mind of a genius who's also slightly unhinged. Instead of using a single timing chain to drive all four camshafts, as most normal engines would, or going for a full gear-driven setup like a proper racing engine, Bugatti and Cosworth have split the difference in the most complicated way imaginable. Here's how it works, as far as anyone can tell from the artfully obscured photos: The crankshaft has a gear at the end. This gear meshes with two other gears, one for each bank of cylinders. And these two gears each have their own smaller gear that drives a timing chain, which in turn operates the camshafts for that bank. So it's a gear-chain-camshaft arrangement, times two. It's the engineering equivalent of taking the scenic route when there's a perfectly good motorway available. Why on earth would they do this? Bugatti and Cosworth aren't saying, which means I'm free to speculate wildly. Perhaps it's because the crankshaft is over three feet long (yes, really) and would twist like a pretzel if asked to drive all 16 cylinders through a single chain. Maybe it's to combat the extreme vibration that occurs when you have what amounts to four four-cylinder engines bolted together. Or perhaps someone at Cosworth just said, "Wouldn't it be cool if..." and nobody had the heart to say no. The Devil's In The Details: Engineering Heaven For The Mechanically Inclined While the timing system is strange enough to warrant its own museum exhibit, the rest of the engine is equally fascinating. There's a vibration damper the size of a dinner plate, which makes sense when you remember that the crankshaft in this thing could double as a javelin in the Olympics. The camshaft variators – the bits that change valve timing – appear to be pinched from an Audi S4's 3.0-liter V6, though Bugatti has rather amusingly crossed out the VW AG marking. It's like buying a designer suit and then snipping out the label, only to sew in your own. The camshafts themselves only vary in timing, not lift, suggesting that Bugatti is relying on the hybrid system to fill in any torque gaps rather than making the valvetrain more complex than it already is. In the released photos, there's also a fascinating glimpse of a three-cylinder test mule on Cosworth's dyno. This isn't some weird three-cylinder Bugatti; it's how Cosworth tests engine fundamentals before committing to building the full monstrosity. It's like practicing a dance routine with just your arms before involving your legs – sensible, but somehow disappointing. The intake system is a work of art in carbon fiber, with four throttle bodies that look suspiciously like off-the-shelf Bosch units. This is typical Bugatti – spend millions developing a bespoke engine unlike anything else on the planet, then use generic throttle bodies because, well, they work. But the pièce de résistance is the sound this thing makes. In the video, the V16 rips to its 9,500rpm redline with a noise that's halfway between a NASCAR Cup car and the gates of hell opening. It's glorious, terrifying, and utterly impractical all at once – which is exactly what a Bugatti engine should be. This is what makes the Tourbillon's V16 so special. In an era where most supercars are downsizing, turbocharging, or electrifying, Bugatti has gone in the opposite direction, creating an engine that's more complex, more powerful, and more ridiculous than anything else on the market. It's the mechanical equivalent of responding to a polite "How are you?" with a three-hour TED Talk about your life story – completely unnecessary, but somehow you can't help but admire the commitment. Whether this unique timing system will prove reliable over the long term is anyone's guess. But then again, if you're buying a Bugatti Tourbillon, reliability probably isn't high on your list of concerns. You're more interested in having the most insane engine possible, even if that means your mechanic needs a Ph.D in quantum mechanics just to change the oil. And in that respect, Bugatti has delivered. This V16 isn't just an engine; it's a statement. A statement that says, "Yes, electric cars might be the future, but before we get there, let's create the most gloriously complicated internal combustion engine the world has ever seen." It's mad, it's beautiful, and it's completely unnecessary. In other words, it's a perfect Bugatti.
