ZenvoDanish hypercar maker Zenvo has been building cars for over 15 years, with all of its previous cars featuring a mid-mounted V8 engine. However, for its latest Aurora hypercar, the brand took the unusual step of developing its own all-new V12 engine in collaboration with Mahle Powertrain. The 6.6L quad-turbocharged engine produces 1,250 horsepower, making it the most powerful V12 ever fitted to a road car according to Zenvo. It's paired with a trio of electric motors developing 600 horsepower, for a combined output of 1,850 horsepower.The engine has reportedly been called "Mjølner," being named after Thor's hammer in Norse mythology. It should make a fittingly thunderous soundtrack at full throttle, but the car will also be able to travel nearly silently for up to 21 miles on all-electric power. Zenvo claims the car's top speed sits somewhere in excess of 280 mph, and it can sprint from 0-62 mph in a mere 2.3 seconds. Assuming those figures are accurate, that makes it one of the fastest cars in the world, but it's priced accordingly. In fact, the Aurora is one of the most expensive hypercars ever built, with a $3.9 million price tag.Mercedes-MaybachWhile Mercedes-Benz S-Class limousines are no longer available with V12 engines, their pricier Maybach counterparts can still be bought with one for now. The 2024 Mercedes-Maybach S680 4Matic starts at roughly $235,000 and features a 6.0L variant of the German automaker's long-running V12 engine. Much like Rolls-Royce's V12 engine, the Maybach engine is designed to be smooth above all else. Power figures aren't really important, although they're impressive here nonetheless — the Maybach packs 621 horsepower distributed to all four wheels through the 4Matic all-wheel drive system.Every other element of the Maybach S680 is exactly as buyers will expect: it's ultra-luxurious, assembled with painstaking attention to detail, and highly customizable. The Maybach is roughly double the price of a standard Mercedes-Benz S Class, but for those buyers who simply must have a V12, it's a price they'll have to pay. For how much longer the V12 will remain available, however, is hard to say. There were reports that Mercedes was looking to phase them out as far back as 2008, but for now, they continue to be offered at the very top of its lineup.De TomasoAnother resurrected Italian brand in the same vein as Bizzarrini, De Tomaso is back making ultra-exclusive hypercars under new Chinese ownership. The latest of those is the P900, the track-only follow-up to the P72. It boasts a bespoke V12 engine built by German engineering firm Capricorn, claimed to be the lightest and shortest V12 ever fitted to a production car. This engine, it should be noted, is not the V12 from the prototype P72, instead being an unrelated design.Its spec sheet is impressive, to say the least: a claimed 12,300 rpm redline, a 900 horsepower output, and design inspiration from LMP1 prototype racers. The P900, and indeed its engine, is still earlier in development than most of the other cars here. So, it's worth taking the car's performance claims as just that — no more than claims — for now. The P900 isn't the first time that De Tomaso has promised V12 power for one of its cars, although, no customer cars have featured such an engine. The P72 prototype initially debuted with a V12, but production cars featured a V8. There's no indication for now that the P900 will follow the same path, however.
