18 MPG combined. Let’s be honest, anyone considering a 2015 Jaguar F-Type V8 S Convertible isn’t prioritizing lower fuel costs. This isn’t about sensible commuting; it’s about theater. It’s about eight cylinders of supercharged performance erupting behind your head as you carve through a canyon road, the wind whipping through what’s left of your rapidly thinning (or perfectly coiffed) hair. The F-Type V8 S Convertible is a statement, a visceral experience, and a rolling piece of automotive sculpture. Its fuel economy is simply a tax you pay for the privilege.

City and highway performance

The EPA estimates for the F-Type V8 S Convertible rate it at 16 MPG in the city and 23 MPG on the highway. The city figure reflects the stop-and-go realities of urban driving, where the supercharged V8 is constantly flexing its muscle, even at low speeds. The highway number demonstrates that, when cruising, the engine isn’t working as hard, but resisting the temptation to dip into the immense power reserve is a challenge. Be prepared to see numbers lower than 16 MPG in the city if you have a heavy foot, as almost any F-Type owner will.

Annual fuel cost

The EPA calculates the annual fuel cost for the 2015 Jaguar F-Type V8 S Convertible at $3,200. This figure is based on driving 15,000 miles per year, with 55% of those miles driven in the city and 45% on the highway, using national average fuel prices. It’s a substantial amount, placing the F-Type squarely in the realm of vehicles with significant running costs. This isn’t a surprise, nor is it likely a deterrent to the target demographic.

Real-world expectations

Real-world fuel economy for the F-Type V8 S Convertible can vary significantly depending on driving style and conditions. Drivers who prioritize performance and regularly engage the supercharger will likely see MPG figures below the EPA estimates. Conversely, those who adopt a more relaxed driving style and spend most of their time on the highway might achieve numbers closer to, or even slightly above, the official ratings. However, understand that owning this vehicle and driving it gently are mutually exclusive ideas. Factor in a strong likelihood of regular “spirited” driving and the associated costs.

How it compares

Compared to its competitors, the 2015 Jaguar F-Type V8 S Convertible’s fuel economy is relatively thirsty, but within the expected range for a high-performance sports car. A Porsche 911 Carrera S Cabriolet, for example, delivers around 22 MPG combined from its flat-six engine, a significant improvement. Even compared to other V8 convertibles, the F-Type lags slightly. A 2015 Chevrolet Corvette Stingray Convertible, while not a direct competitor in terms of luxury, achieves around 20 MPG combined with its V8 powertrain. This comparison matters because even among buyers who aren’t hyper-focused on fuel economy, there can be an awareness of relative efficiency within the segment.

Tips to maximize efficiency

Resist the urge to constantly bury the accelerator. The supercharger is intoxicating, but using it sparingly can significantly improve your fuel economy. Learn to appreciate the engine’s torque curve and use it to your advantage, rather than relying solely on raw horsepower. Quick bursts of acceleration followed by coasting (when safe) are preferable to consistently heavy throttle input.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, which reduces fuel economy. Check your tire pressure regularly and inflate them to the recommended levels. Consult the sticker on the driver’s side doorjamb for optimal pressures.

Minimize idling. Idling consumes fuel without covering any distance. If you’re stopped for more than a minute or two, turn off the engine. This is especially true in urban environments with frequent stoplights.

Service the engine regularly. A well-maintained engine is a more efficient engine. Follow the manufacturer’s recommended maintenance schedule, including oil changes, air filter replacements, and spark plug replacements. Keeping the engine in top condition will help it achieve its optimal fuel economy.

Use premium fuel. The supercharged V8 in the F-Type V8 S Convertible requires premium fuel. Using lower-octane fuel can reduce performance and fuel economy, and could potentially damage the engine over time. Stick to the manufacturer’s recommendation for the best results.
