The 2018 Jaguar F-Type Convertible with the supercharged 3.0L V6 gets 23 MPG combined, but that’s likely not the primary reason someone buys one. It’s the price you pay for open-top motoring with a thrilling exhaust note. This Jaguar prioritizes visceral thrills over minimizing gas consumption. Think of it as a weekend indulgence, a joyful machine that prioritizes emotion over efficiency.

City and highway performance

The EPA estimates the F-Type Convertible 3.0L at 20 MPG in the city and 28 MPG on the highway. These numbers reflect the car’s inherent duality. In the city, the supercharged V6 is always eager to respond, even with moderate throttle inputs. Stop-and-go traffic readily exposes the engine’s thirst. However, on the open road, the F-Type settles into a more relaxed cruise. The eight-speed automatic transmission finds the optimal gear for efficiency. The 28 MPG highway rating is achievable if you resist the urge to floor it, a temptation that requires considerable willpower given the intoxicating exhaust note.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2018 Jaguar F-Type Convertible 3.0L at $2,500. 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. It also assumes the use of gasoline priced at the national average. Your actual fuel costs will vary depending on your driving habits, the type of fuel you use, and local fuel prices. However, $2,500 provides a reasonable benchmark for potential owners to consider.

Real-world expectations

While the EPA estimates provide a useful baseline, real-world fuel economy will likely deviate, especially for F-Type owners. The car’s performance invites spirited driving, which impacts fuel consumption. A heavy foot can easily drop combined MPG into the high teens. Conversely, mindful driving on long highway stretches might yield slightly better than the EPA’s 28 MPG rating. Consider the official numbers a best-case scenario that demands restraint. Check F TYPE MPG across all years to see how 3rd-party reporting is coming in.

How it compares

The F-Type’s fuel economy is consistent with other performance-oriented convertibles. A 2018 Porsche 718 Boxster S (2.5L turbo) achieves around 22 MPG combined, placing it in a similar efficiency category, despite the different engine architecture. A BMW Z4 M40i from the same era, equipped with a 3.0L turbo inline-six, manages around 25 MPG combined. While the BMW edges out the Jaguar in efficiency, the F-Type counters with a distinctive character and a supercharged engine that delivers instant throttle response in a way that turbocharged engines often struggle to match. Those prioritizing lower fuel costs in a similar package might also consider a Mazda MX-5 Miata, which delivers close to 30 MPG combined.

Tips to maximize efficiency

Smooth, consistent acceleration is crucial. Avoid abrupt starts and stops, as these actions burn unnecessary fuel. Let the car build speed gradually, allowing the automatic transmission to shift smoothly and efficiently. The supercharger delivers its power evenly across the rev range, eliminating the need to constantly push the engine to its limits.

Use the F-Type’s driving modes. The “Eco” or “Comfort” mode softens throttle response and encourages the transmission to upshift earlier, optimizing fuel efficiency. While these modes may diminish the car’s sporty character, they can make a noticeable difference in stop-and-go traffic or during leisurely cruises.

Proper tire inflation is important. Underinflated tires increase rolling resistance, forcing the engine to work harder and consuming more fuel. Check your tire pressure regularly and inflate to the manufacturer’s recommended specifications, typically found on a sticker inside the driver’s side door jamb.

Minimize aerodynamic drag. Top-down driving is a primary appeal of the F-Type Convertible, but it negatively impacts fuel efficiency, especially at higher speeds. Consider raising the top for longer highway journeys to reduce drag and improve MPG. Also, remove any unnecessary items from the car’s interior and trunk, as added weight can also reduce fuel efficiency.

Regular maintenance is essential for optimal performance. Ensure that the engine is properly tuned, the air filter is clean, and the spark plugs are in good condition. Addressing minor maintenance issues promptly can prevent them from escalating into major problems that negatively impact fuel economy and long-term reliability. Consider reviewing all Jaguar fuel economy data to compare other models.
