A Swedish Automaker Is Using 3D Printing To Make The World's Fastest Car

Part of the trick is an engine that produces over 1,300 horsepower - an awesome feat in itself. The other part is getting the weight of everything else down, which means the chassis, body, and even seats are carbon, made with high modulus fibers that cut weight down even more.
But the Swedes didn't stop there: To save a mere 400 grams (.88 pounds), they 3D print its exhaust end piece from titanium instead of aluminum. Mainstream automakers are just getting to aluminum now, because it's so much lighter than steel.
According to Jalopnik, the exhaust tip is the largest piece of titanium ever 3D printed, and it takes three days to produce. But it saves that little bit of weight, and keeps the supply chain simpler. So it's worth it.
Here's a close-up of the exhaust tip:
