The British Government wants them - along with diesels - banned from sale in 2040 and major car makers like Volkswagen have announced they will focus on electric drivetrains.
But before then, Aston Martin has vowed to 'create the ultimate expression of the internal combustion engine'.
The 6.5-litre V12 motor produces a staggering 1,000bhp and will soon grace the chassis of the £2.5million Valkyrie hypercar:
Just 175 Valkyrie's are due to be built in partnership with the Red Bull F1 team.
Of those, 150 will be road-going cars and the remaining 25 upgraded to track-only AMR Pro versions - a £3million toy for the world's billionaires - and all will feature this monumental 65 degree angle 12-cylinder powerplant.
Aston Martin is adamant that only a naturally-aspirated engine will do, so there are no turbochargers or superchargers found here.
In the Gaydon brand's own words: 'the greatest driver's car of the modern era demands an internal combustion engine that sits at the absolute pinnacle for performance, excitement and emotion. This means the uncompromising purity of natural aspiration.'
And it's quest to create the ultimate powerplant has resulted in this absolute masterpiece built in conjunction with engine specialists Cosworth.
Peak power of 1,000bhp, it says, is achieved at 10,500rpm. The redline is a staggering 11,100rpm - a stat that's unprecedented for a naturally-aspirated engine in today's world of ever restrictive emissions regulations.
Maximum torque is 740Nm at 7,000rpm, so there's plenty of grunt to play with.
And that's not all. All of these figures are purely delivered by the internal combustion engine alone.
With the Valkyrie also getting a battery hybrid system, total performance outputs are going to be even higher - though Aston Martin hasn't revealed that combined stats of the two powertrains just yet.
To keep weight to an absolute minimum, the major castings - including the block, cylinder heads, sump and structural cam covers - are machined from solid material. This also includes the Titanium conrods and F1-spec pistons.
The result is an engine that weighs just 206kg.
Not only is it light but it's also fundamental to the structure of the car, because it's fully structural engine - that means it's part of the construction that holds the vehicle together, just like an F1 racer and unlike any other production road car on sale.
Bruce Wood, Cosworth managing director, said of the project said: "Being asked to create a naturally aspirated V12 engine fit for what will surely be one of the most iconic cars of all time is an immense source of pride for Cosworth.
"Decades in F1 taught us to expect a pretty demanding specification from someone with Adrian Newey's unsurpassed track record, but when we started talking about specifics of power, weight, emissions compliance and durability combined with ever harder and sometimes conflicting targets, we knew this would be a challenge like no other.
"It's been a fantastic partnership between Aston Martin, Red Bull and Cosworth with each party bringing a distinct clarity of vision that has proved essential in delivering an internal combustion engine way beyond anything previously seen in a road car application."
Dr. Andy Palmer, Aston Martin president and group chief executive, added: "To anyone with a drop of petrol in their blood, a high-revving naturally aspirated V12 is the absolute pinnacle. Nothing sounds better or encapsulates the emotion and excitement of the internal combustion engine more completely.
"Despite the apparently insurmountable challenges it presented, there was never any question that the Aston Martin Valkyrie would make do with anything less.
"From the outset the team at Cosworth were unflinching in their commitment to achieving benchmarks which pushed the boundaries of the possible. The result is a quite extraordinary engine. One which I doubt will ever be surpassed."
Aston Martin has already confirmed that all examples of the Valkyrie have been promised to customers who will receive first orders from this year.
