Answers: How do the naturally aspirated V12 engines in the Aston Martin Valkyrie and Gordon Murray T.50 work and compare?

• Aston Martin Valkyrie engine specs
• Gordon Murray T.50 engine specs
• Naturally aspirated V12 engines
• Brake mean effective pressure in high-revving engines
• Gear-driven camshafts in race engines
• Port injection vs direct injection

What it concludes

• The Aston Martin Valkyrie's 6.5L V12 produces 1,000 horsepower at 10,500 RPM and 546 lb-ft of torque at 7,000 RPM while revving to 11,100 RPM.
• The Aston Martin Valkyrie engine serves as a structural member of the vehicle, helping reduce weight while withstanding significant aerodynamic and chassis stresses.
• The engine achieves 153.8 horsepower per liter using short strokes (between 67.6 mm and 70.3 mm) and large bores (between 99 mm and 101 mm).
• Using port injection instead of direct injection allows the Valkyrie engine to meet its power targets without requiring a particulate filter.
• The Gordon Murray T.50 engine is a 3.98-liter V12 producing 650 horsepower at 12,100 RPM, achieving 163 horsepower per liter.
