Why this is the Goldilocks of engines: Why do supercars from the Bentley Flying Spur and Lamborghini Temerario to the McLaren 750S and Mercedes-AMG GT63 rely on the 4.0-litre twin-turbo V8? | Analysis

I’m okay with picking pattern progressions, but begin to fall short when the pressure of upper level IQ testing starts to bring me undone. That said, even I could detect the clear sequence of super performance carmakers following one another into the world of the 4.0-litre, twin-turbo V8.A slew of British, German and Italian brands using the same performance vs consumption vs emissions equation to propel their exotic machines towards the horizon at warp speed with maximum efficiency.So, why did white-coated boffins from all points of the automotive globe come up with the same engine configuration, capacity and induction answer?Well, at the recent global launch of the Lamborghini Temerario (a 4.0L twin-turbo V8 hybrid) we asked Lambo’s Chief Technical Officer (and drift king) Dr. Rouven Mohr exactly that.He confirmed the broadly accepted answer that an individual cylinder volume of 500cc is the magic number.That’s right, the capacity that took the ‘Wollongong Whiz’ Wayne Gardner and ‘The Master of going Faster’ Mick Doohan to 500cc World Motorcycle Championship glory is the Goldilocks zone for an individual engine cylinder. And that’s because a cylinder of that size, ideally undersquare (with a stroke length exceeding its bore diameter), optimises the combustion process thanks to a relatively small internal surface to volume ratio (as the piston nears top dead centre) which helps improve fuel efficiency while producing optimum power and minimising C02 and NOx emissions.So, 500 times eight equals 4000, which, with the benefit of forced induction pushes the golden ratio to its maximum.And Lamborghini should know because the all-new (L411) unit it developed for the Temerario produces 588kW on its own, before a trio of electric motors tips in another 89kW for a total output of 677kW (920hp).Two turbos producing 2.5 bar located in the engine’s ‘hot vee’ optimise packaging and thermal management; titanium conrods reduce rotating mass; a flat plane crank delivers an even firing order and super hard finger followers in the valvetrain allow more aggressive cam profiles. The result? A 10,000rpm rev ceiling, which is… nuts.Other brands within the Volkswagen Group portfolio are on the same train, like Audi’s SQ7 and SQ8 with Bentley and Porsche directly sharing engine tech.And what about Mercedes-AMG with the GT63 and SL63 or McLaren just about matching Lambo for specific power output with its 750S rocketship?But hands up those who remember JLR’s ‘Ingenium’ modular engine family. Three-, four- and six-cylinder units built around 500cc cylinders. BMW Group with its triple, four- and six-cylinder engines, along with many others have also struck on the 500cc formula. But maybe Lamborghini President and CEO Stephan Winkelmann has the most compelling reason for joining the club.While acknowledging the capacity of the cylinder premise - “Six cylinder is usually three litres, eight is four and 12 is six” - he lets slip that the 4.0L thing “is also a matter of taxation in a lot of countries”. So, follow engine efficiency or follow the money, the 4.0-litre, twin-turbo V8 answer is the same.

End of an era at Crewe: 2025 Bentley Continental GT Speed ditches W12 for hybrid V8 to challenge Porsche Panamera and Aston Martin DB12

Yet another ‘most powerful’ brand record is broken, this time by the 2025 Bentley Continental GT Speed plug-in hybrid. Although exciting, it marks a sad end to Bentley’s unique W12 engine configuration after production ceased at Crewe in April 2024. The revised cross-plane single-turbo 4.0-litre V8 petrol engine is allied to a 140kW/450Nm electric motor integrated into the eight-speed transmission. The system punches out 575kW and 1000Nm, enough to get the grand tourer from rest to 100km/h in 3.2 seconds. For the first time, the Continental GT hardtop is launched alongside its rag-top GTC relation – excitingly available with tweed as a material choice for the hood. Though visually similar to the car it replaces, Bentley's muscular fourth-generation Continental GT features 68 per cent all-new componentry. The Continental GT is the first mainstream non coach-built model since the 1959 S2 to feature single headlights; modern Matrix LED items, naturally. An active anti-roll system powered by the 48-volt electrical system, new ESC programming and a rear-axle active eLSD help harness all the punch. Mounted behind the rear wheel, the larger 25.9kWh battery allows 81km of electric-only driving range (WLTP) and can charge in two hours and 45 minutes at 11kW (AC). Bentley claims a ‘perfect’ 49:51 weight distribution for the all-wheel drive grand tourer. To show off the new powertrain’s capability, Bentley set a unique ‘underwater speed record’ using the world’s longest tunnel. The two-door hit 335km/h in the 14.4km long Ryfylke undersea road tunnel in Norway, running on renewable biofuel and green electricity. To haul up the Continental GT Speed, steel brakes are standard though Carbon-Silicon-Carbide brakes with 440mm front and 410mm rear rotors are optionally available. Inside, luxury and personalisation is the name of the game for the four-seater. The Continental GT has 20-way power-adjust seats with quilted leather upholstery, 'Auto Posture Adjust' and automatic heating plus ventilation.The Continental GT gets a 650-watt stereo as standard with both 16-speaker 1500W Bang & Olufsen or flagship 18-speaker 2200W Naim sound system with 'Active Bass Transducers' available. Australian pricing and specification is yet to be confirmed for Bentley’s Porsche Panamera, Aston Martin DB12 and Ferrari 12Cilindri rival.
