The Audi Q5 is the established premium mid-size SUV — larger and more practical than the Q3 but more manageable than a Q7. It sits in the competitive class alongside the BMW X3, Volvo XC60, and Mercedes GLC, and has consistently been one of the best-regarded options in that space for interior quality, refinement, and long-term reliability. For Isle of Wight buyers who want a premium SUV with quattro AWD, a comfortable ride, and strong residual values, the Q5 is a natural choice in the used market.
Which Generation to Buy
FY Audi Q5 (2017–present): The generation to buy. The FY is built on Audi's MLB Evo platform (shared with the Audi A4, A5, and Porsche Macan), with a significantly better interior, more technology, and better engines than the 8R. The FY received a facelift in 2020 with updated headlights and infotainment. Available from around £20,000 for early 2017–2018 examples.
8R Audi Q5 (2008–2017): The first generation. A capable SUV but now showing its age — the interior quality and technology lag well behind the FY. The 3.0 TDI diesel in the 8R is a strong engine but the model is now genuinely old. Only relevant as a budget premium SUV at under £12,000.
For most buyers, the FY (2017+) is the correct generation.
Audi's Engine Naming in the Q5
| Audi Name | Engine | Power |
|---|---|---|
| 35 TDI | 2.0 diesel | 163bhp |
| 40 TDI | 2.0 diesel | 204bhp |
| 45 TFSI | 2.0T petrol | 245bhp |
| 55 TFSI e | 2.0T + electric (PHEV) | 362bhp system |
Which Engine for IoW?
45 TFSI (2.0T, 245bhp, petrol): The recommended choice for island buyers. Smooth, refined, and strong enough for the Q5's size. Real-world economy of 33–39mpg in mixed island driving. No DPF. Standard quattro AWD. The natural choice for buyers who do predominantly island driving.
40 TDI (2.0D, 204bhp, diesel): The most widely available FY Q5. Economy of 44–52mpg makes it compelling for frequent mainland ferry crossings. The DPF concern for island-only driving applies — only choose diesel if you regularly cover longer distances on the mainland.
55 TFSI e (PHEV, 362bhp system): The plug-in hybrid. A 14.1kWh battery gives approximately 35–40 miles of electric range (WLTP) — practically covering most IoW daily driving on electricity alone. Economy of 100–170mpg under PHEV test conditions (real-world varies by charging frequency). The best choice for buyers with home charging who want to minimise fuel costs on the island.
FY Q5 vs BMW X3: Which Is Right for IoW?
| Audi Q5 (FY) | BMW X3 (G01) | |
|---|---|---|
| Platform | MLB Evo | CLAR |
| AWD system | Quattro | xDrive |
| Boot space | 550 litres | 550 litres |
| Interior quality | Premium | Premium |
| Driving dynamics | Comfort-biased | More driver-focused |
| Ride quality | More comfortable | Firmer |
| Running costs | Similar | Similar |
| Price used (comparable) | Similar | Similar |
The Q5 is the more comfortable ride for IoW varied road surfaces. The X3 is more rewarding to drive. Both are similarly matched in quality and capability. The Q5 has a slight advantage in interior detail quality; the X3 in driving engagement. Often the decision comes down to brand preference and which used example is available at the right price.
Known Issues to Check
DPF (40 TDI diesel): Covered above — the DPF concern for short island trips is real. Ask about typical driving patterns. A Q5 used mainly for island errands risks blocked DPF requiring £500–£1,500 repair.
S tronic gearbox: The 7-speed S tronic dual-clutch on some 45 TFSI models can show shudder at low speeds. Test for smooth pull-away from standstill. DSG/S tronic fluid changes at correct intervals improve this.
Panoramic sunroof drainage: Like many premium SUVs, the Q5 panoramic sunroof drainage can block with debris. Check for damp carpets or musty interior smell — the same issue seen on Mercedes and BMW panoramic roof cars.
PHEV high-voltage battery: The 55 TFSI e's high-voltage battery carries Audi's warranty for 8 years/160,000km from new. Ask for charging history and check that the electric range is within expected parameters for the age.
Air suspension (optional): Some Q5s were optioned with air suspension. Comfort is excellent but compressor and air bag failures can occur. Check for even ride height at all four corners.
IoW Buying Tips
At 4.66m long and 1.89m wide, the FY Q5 is a large car for island use. It fits standard UK parking bays but narrow rural lanes in the south and west of the island require more care than in a smaller car. The raised driving position is helpful on hedge-lined IoW roads.
Premium SUV supply on the island is limited — typically a handful of examples available at any time. Company lease returns and PCP purchases are the most common history. Run an HPI check — finance on new Q5s is almost universal.
Audi main dealer servicing is expensive. Independent Audi/VW specialists (which can service the Q5 using genuine or quality parts) bring this to a more reasonable level. Insurance groups are high (groups 35–45 typically).

Frequently Asked Questions
Is the Audi Q5 a reliable car?
The FY Q5 (2017+) has a good reliability record. The MLB Evo platform is well-proven across multiple Audi models. The 45 TFSI petrol engine is reliable and straightforward. The S tronic gearbox needs correct fluid change intervals. The main practical issues to check are panoramic sunroof drainage and (on diesel models) DPF health. With documented service history, the FY Q5 is a capable and durable premium SUV.
What is the difference between the Audi Q5 and Q3?
The Q5 is significantly larger (4.66m vs 4.48m), heavier, and more powerful than the Q3. The Q5 has a 550-litre boot vs the Q3's 530 litres. The Q5 uses Audi's MLB Evo platform (same as the A4 and A5), while the Q3 uses the smaller MQB platform. The Q5 is positioned higher in Audi's range with more powerful engine options, including the 55 TFSI e PHEV. The Q3 is more nimble and easier to park in island car parks; the Q5 has substantially more interior space.
Is the Audi Q5 worth the premium over a BMW X3 on the Isle of Wight?
They're similarly priced and similarly capable. The Q5's ride quality is slightly more comfortable — a meaningful advantage on the island's varied road surfaces. The X3 is more engaging to drive on the twistier island roads. Both have excellent interior quality. The decision often comes down to brand preference or which specific used example (mileage, specification, history) is available at the right price.
Is the PHEV Audi Q5 worth buying on the Isle of Wight?
Yes, if you have home charging. The 55 TFSI e offers approximately 35–40 miles of electric range — enough to cover most daily IoW driving on electricity without using the petrol engine. The IoW's domestic charging infrastructure means most island buyers with off-road parking can charge overnight. The combined electric/petrol system is also better-suited to IoW's stop-start driving than a pure diesel. The PHEV commands a significant premium used — verify that the high-voltage battery is healthy before purchase.
How big is the Audi Q5?
The FY Q5 is 4.66m long and 1.89m wide — a large car by island standards. Standard UK car parks accommodate it, and the Newport ferry approach and most island car parks present no difficulty. However, the narrow lanes in rural IoW areas (Brighstone, Chale, Rookley, Shorwell) require more care than a smaller car. The elevated driving position improves visibility on hedged roads.
