The Zenvo Aurora will go on sale subsequent yr with probably the most highly effective V12 ever put in in a manufacturing automobile. It is an engine named for Thor’s hammer that may brutally pound the pavement whereas one way or the other managing to fulfill emissions requirements around the globe. How did the 6.6-liter beast come collectively? Zenvo and MAHLE Powertrain dive in to clarify how this engine got here to be.
When Zenvo got here to MAHLE, it was seeking to get just a bit extra energy from its TSR’s V8 engine. They have been having bother with emissions, and the engine was at its absolute max. So MAHLE mentioned it might do a bespoke engine for it. One that might go far past what the prevailing one was able to.
Many years Of Expertise In Each Choice
Even what number of turbochargers to put in was a tricky choice. A quad-turbo setup would ship barely higher responses than two, nevertheless it was more durable to do. MAHLE made it work. The corporate’s staff has many years of expertise creating engines for racing and efficiency vehicles of all kinds and energy ranges.
However the look of the engine was essential too. MAHLE needed the 600 elements to appear like a murals, in recognition of the efficiency it might ship and the automobile during which it will be positioned.
“The largest goal we had on the time was 450 km/h [280 mph],” mentioned MAHLE Powertrain Gross sales and Advertising and marketing Director John Hollingworth. “We needed to work out what measurement engine, and what efficiency does the engine have to do” as a way to get that. “The opposite half was the 9,800 rpm. The sound of the high-revving engine.”
“We’ve got taken many dangers and plenty of challenges by going with this stage of specification,” mentioned Chief Engineer Javier Castane. “The profit could be that the automobile is on the similar stage as all the opposite hybrid [hypercars] on the market.”
MAHLE Thinks This Engine Would possibly Go Unchallenged
This V12 engine is a feat Hollingworth thinks might by no means be replicated. He rightfully factors out that with electrification and fashionable rules, the times of boutique corporations constructing bespoke engines is nearing its finish. Which might not be nice for MAHLE, since that is their enterprise.
The Zenvo Aura’s 6.6-liter V12 and its 4 turbochargers can produce 1,250 horsepower and 1,032 pound-feet of torque. The engine cannot fairly meet the ten,000 rpm redline it had initially deliberate, however when it hits 9,800 you are in all probability by no means going to overlook the additional 200 revs. One other 600 horsepower comes from the hybrid drive system, which can assist the automobile obtain immense speeds.
Zenvo plans to get this automobile to market with manufacturing beginning in 2026. Then it could have a look at new prospects for the engine. That might embrace the identical engine in smaller vehicles from the supercar firm, or, because of the modular design, V10 or V8 variants that better-suit the vehicles during which they are going to be used.
MAHLE Powertrain was born from engine legends Cosworth. The corporate was absorbed into MAHLE in 2005 after being separated from Cosworth Racing by Audi, which was offered to Ford. MAHLE Powertrain develops gasoline engines and electrified powertains together with doing OE design work in addition to validation and research.
