How Fast Is a V8 Twin‑Turbo?

It varies widely by vehicle, but modern twin‑turbo V8 cars typically accelerate from 0–60 mph in about 2.5–3.5 seconds and reach top speeds from an electronically limited 155 mph to 200–211+ mph; the most extreme hypercar applications post world‑class acceleration records. That range reflects everything from sedans and SUVs to supercars and track specials, all using the same core idea: two turbochargers feeding a V8 to deliver big power and torque.

What “V8 twin‑turbo” means

A twin‑turbo V8 pairs an eight‑cylinder engine with two turbochargers, typically in a parallel layout (one turbo for each bank of cylinders). The setup—often packaged in a “hot‑vee” configuration with turbos in the valley—boosts intake pressure to produce far more power than a naturally aspirated equivalent, while improving low‑rpm torque and maintaining a compact footprint. In practice, it delivers rapid acceleration and strong mid‑range pull, with performance shaped by tuning, gearing, drivetrain, weight, aerodynamics, and tire grip.

Real‑world performance ranges

Because “how fast” can mean either outright top speed or how quickly a car gains speed, it helps to look at common benchmarks. The figures below summarize what you can expect from recent twin‑turbo V8 cars across segments.

At‑a‑glance metrics

The following list outlines typical performance ranges for modern twin‑turbo V8 vehicles, from sporty SUVs to supercars and hypercars.

• 0–60 mph: roughly 2.5–3.0 seconds for high‑end supercars; 3.0–3.8 seconds for sports sedans and performance SUVs.
• 0–100 km/h (0–62 mph): about 2.5–3.2 seconds for supercars; 3.3–4.0 seconds for sedans/SUVs.
• 0–200 km/h (0–124 mph): approximately 7–8 seconds for top supercars; 9–12 seconds for fast grand tourers and sedans.
• Quarter‑mile: commonly 10.0–11.5 seconds for supercars; 11.5–12.5 seconds for powerful sedans/SUVs (conditions and tires matter).
• Top speed: often limited to 155 mph (250 km/h) in many German performance cars; 180–205 mph derestricted; 211+ mph for the quickest supercars.
• Power: broadly 450–800+ hp in mainstream performance models; 900–1,600+ hp in specialized or hybrid‑assisted exotics.

These ranges overlap because a twin‑turbo V8 is only one piece of the puzzle. All‑wheel drive, launch control, hybrid assistance, and tire compound can swing results by surprising margins.

Notable examples on the road now

To ground the ranges above, here are representative, current or recent models using twin‑turbo V8s, with manufacturer‑quoted figures where available.

• McLaren 750S (4.0L twin‑turbo V8, ~740 hp): 0–60 mph 2.7 s; top speed 206 mph.
• Ferrari F8 Tributo (3.9L twin‑turbo V8, 710 hp): 0–62 mph 2.9 s; top speed 211 mph.
• Ferrari SF90 Stradale (twin‑turbo V8 hybrid, 986 hp combined): 0–62 mph 2.5 s; top speed 211 mph.
• Aston Martin DB12 (4.0L twin‑turbo V8, 671 hp): 0–60 mph 3.5 s; top speed 202 mph.
• Mercedes‑AMG GT 63 (2024, 4.0L twin‑turbo V8, 577 hp): 0–60 mph about 3.1 s; top speed 196 mph.
• Audi RS6 Avant Performance (4.0L twin‑turbo V8, 621 hp): 0–62 mph about 3.4 s; top speed up to 190 mph with RS Dynamic Plus.
• BMW M5 (2025, 4.4L twin‑turbo V8 PHEV, 717 hp system): manufacturer estimates 0–62 mph ~3.5 s; top speed up to 190 mph with M Driver’s Package.
• Lamborghini Urus Performante (4.0L twin‑turbo V8, 657 hp): 0–62 mph 3.3 s; top speed 190 mph.
• Porsche Cayenne Turbo GT (4.0L twin‑turbo V8, ~650 hp): 0–62 mph 3.3 s; top speed 189 mph.
• Koenigsegg Jesko (5.0L twin‑turbo V8, up to 1,600 hp on E85): set a 0–400–0 km/h record of 27.83 s in 2024; top‑speed figure not publicly verified as of 2025.

Taken together, these examples show the breadth of the twin‑turbo V8’s reach—from daily‑drivable wagons and SUVs to supercars and record‑chasing hypercars.

What determines how fast it feels

Raw horsepower matters, but other variables shape both measured speed and seat‑of‑the‑pants sensation. The factors below explain why two twin‑turbo V8s can perform very differently.

• Drivetrain: All‑wheel drive enables explosive launches; rear‑drive cars may be traction‑limited off the line but faster at high speeds.
• Weight and aero: Lighter cars accelerate and brake better; slippery aero aids top speed and stability.
• Gearing and shift speed: Close ratios and quick, smart programming sharpen acceleration.
• Tires and surface: Compound, temperature, and road prep can swing 0–60 times by tenths.
• Cooling and repeatability: Heat soak can reduce power; robust cooling maintains performance in back‑to‑back runs.
• Electronic limits: Many cars are speed‑limited from the factory; optional packages can raise the cap.
• Hybrid assistance: Electric torque fill can trim lag and improve low‑speed punch.

In short, the same engine architecture can deliver very different outcomes depending on how the entire vehicle package is engineered and set up.

How it compares

Against naturally aspirated V8s, twin‑turbo V8s typically offer more torque across the rev range and quicker real‑world pace, especially at altitude. Compared with twin‑turbo V6s, they generally produce higher peak outputs and a more effortless, long‑legged feel. Electric performance cars often beat them off the line with instant torque, but twin‑turbo V8s remain formidable at high speeds and in sustained, repeated performance use when supported by strong cooling and braking systems.

Summary

A twin‑turbo V8 can be very fast indeed: think 0–60 mph in roughly 2.5–3.5 seconds and top speeds from 155 mph (limited) to well over 200 mph, with specialized hypercars pushing acceleration records even further. The exact answer depends on the vehicle’s weight, drivetrain, aerodynamics, gearing, tires, and, increasingly, hybrid assistance. If you tell us the specific model you’re considering, we can pinpoint its likely acceleration and top‑speed figures.

How much horsepower does a twin-turbo add to a V8?

A twin-turbo setup can add anywhere from 50 to over 100% more horsepower to a V8 engine, depending heavily on boost pressure, engine modifications, turbocharger size, and the engine’s original output. For example, a 500-horsepower V8 could see its output more than double, potentially reaching over 1,000 horsepower with a properly matched twin-turbo system and supporting modifications. 
Key Factors Influencing Horsepower Gains

• Boost Pressure: Opens in new tabHigher boost levels force more air into the engine, resulting in greater power output, but require stronger engine components to handle the increased pressure. 
• Engine Modifications: Opens in new tabFor major power increases, supporting modifications like upgraded fuel delivery, an optimized air intake, and a more robust engine block are necessary to prevent damage. 
• Turbocharger Size and Selection: Opens in new tabThe size and design of the turbos must be matched to the engine’s displacement and desired power goals for optimal efficiency and performance. 
• Engine Size: Opens in new tabLarger engines can generally handle more boost and generate greater power than smaller engines. 

Examples

• Low Boost: A twin-turbo system with conservative boost can add 50 to over 100 horsepower to a V8, according to CarParts.com. 
• High Performance Builds: With a 500-horsepower V8, a twin-turbo system and the right supporting mods can lead to a potential output exceeding 1,000 horsepower, notes Titan Turbo Service. 

In essence, the horsepower gain isn’t a fixed number but rather a significant increase that is directly tied to the complexity of the setup and the desired power target.
