2026 Bentley Bentayga Speed: 641 Hp V8 Redefines Luxury

The 2026 Bentley Bentayga Speed marks a pivotal shift for the British marque, retiring the iconic W12 engine in favor of a highly tuned 4.0-liter twin-turbo V8. This powerhouse delivers 641 horsepower and 627 lb-ft of torque, surpassing the outgoing model’s output while maintaining Bentley’s hallmark blend of brute force and refined elegance. Despite weighing around 2.5 tonnes, it accelerates from 0-60 mph in just 3.4 seconds, proving that fewer cylinders do not equate to diminished thrills.

Powertrain Transformation: From W12 to V8 Supremacy

Bentley’s decision to phase out the W12, which ended production in 2024, aligns with broader industry trends toward efficiency without sacrificing excitement. The new V8, shared in architecture with models like the Porsche Cayenne Turbo GT and Lamborghini Urus Performante, features larger turbos and reinforced internals for its elevated performance. Official figures from Bentley confirm 650 PS (approximately 641 hp) and 850 Nm (627 lb-ft), available from 2,250 rpm, enabling seamless power delivery across the rev range.

This engine pairs with an eight-speed automatic transmission and all-wheel drive, incorporating a new Launch Control system for the first time in the Bentayga lineup. The result? Quicker launches than the previous W12 Speed, which managed 3.9 seconds to 60 mph, and a top speed of 193 mph—contingent on optional carbon-ceramic brakes. Fuel economy stands at 21.6 mpg with 298 g/km CO2 emissions, offering a theoretical range of 403 miles.

Chassis and Dynamics: Agility Beyond Expectations

At 5,125 mm long, 1,998 mm wide, and 1,728 mm tall, the Bentayga Speed defies its dimensions with exceptional poise. A revised Sport mode sharpens steering response, increases damping stiffness by 15 percent, and employs brake torque vectoring alongside four-wheel steering for flatter cornering and reduced body roll. Relaxed stability controls permit controlled drifts, enhancing driver engagement on twisty roads.

Reviewers praise its balance: the V8’s thunderous soundtrack, enhanced by an optional Akrapovic exhaust, complements the chassis’ precision, making it feel lighter and more responsive than rivals like the Range Rover Sport SVR or Aston Martin DBX707. Comfort and Bentley modes retain the SUV’s cruising prowess, with adaptive air suspension smoothing imperfections effortlessly.

Design and Aesthetic Enhancements

Exterior updates are subtle yet distinctive, including unique badging, orange accents on vents and calipers, and 22-inch wheels shod in bespoke Pirelli P Zero tires. The Mulliner personalization division offers extensive customization, from diamond-quilted leather to wood veneers, ensuring no two Bentaygas are identical. Inside, the cabin exudes luxury with rotating displays, massaging seats, and Naim audio systems, all illuminated by ambient lighting.

Luxury Features and Interior Opulence

• Seating: 5 seats with heating, ventilation, and massage functions; optional rear entertainment screens.
• Infotainment: 10.9-inch touchscreen with Apple CarPlay, Android Auto, and wireless charging.
• Audio: 1,280-watt Naim system with 19 speakers for immersive sound.
• Assists: Night vision, adaptive cruise, and rear cross-traffic alert for safety.

These elements position the Bentayga Speed as a mobile lounge, ideal for long journeys or track days alike.

Why Ditch the W12? Engineering Insights

The W12’s retirement stems from emissions regulations and Bentley’s pivot to hybrids elsewhere, like the Continental GT Speed’s 771-hp Ultra Performance Hybrid. Yet, the Bentayga Speed remains pure internal combustion, prioritizing raw emotion over electrification. This V8 not only matches but exceeds prior performance, with a more responsive throttle and evocative exhaust note.
