Used BMW X5 (2013-2018) Buyer’s Guide: Prices, Engines, Costs

The third-generation BMW X5, produced from 2013 to 2018, stands out as a benchmark in the luxury SUV segment for its blend of dynamic driving, spacious interiors, and advanced powertrains. On the used market, this model retains strong value due to robust residuals, making it a premium but worthwhile investment for enthusiasts. Diesel variants dominate availability and offer impressive efficiency, while rarer petrol and hybrid options cater to specific needs. This guide delves into pricing trends, fuel consumption figures, ongoing expenses, engine choices, and practical buying advice to help you navigate the marketplace confidently.

Market Pricing and Value Retention

Prices for used BMW X5 Mk3 models remain elevated compared to mainstream SUVs, thanks to excellent depreciation resistance. Entry-level diesel examples from 2013-2015 typically start around £20,000-£25,000, depending on mileage and condition, while well-equipped later models approach £35,000. Petrol versions command a premium due to scarcity, often 20-30% higher than equivalent diesels. High-spec cars with extras like adaptive suspension or premium audio push values further upward.

Residuals benefit from the X5’s desirability, limiting bargain hunts but ensuring long-term stability. For instance, a 2018 diesel with average mileage might fetch £30,000+, reflecting demand for its refined performance. Buyers should prioritize vehicles with full service histories, as these hold value best. Regional variations exist; urban areas see higher prices due to competition.

Fuel Efficiency Across Powertrains

Diesel engines lead in real-world economy, ideal for high-mileage drivers. The 25d rear-wheel-drive model achieves up to 50.4mpg combined with 149g/km CO2, dropping slightly to 48.7mpg for xDrive versions at 154g/km. Mid-range 30d and 40d options deliver around 45.6mpg (162-166g/km CO2), balancing power and frugality. The potent M50d manages 42.2mpg despite 177g/km, outperforming many rivals.

Petrol variants lag significantly. The 50i V8 returns 27.2mpg (242g/km), while the X5 M hits just 25.4mpg (258g/km), suiting performance seekers over efficiency hunters. US EPA figures align closely: xDrive35d at 22mpg combined (19 city/26 hwy), xDrive35i at 19mpg (16/23).

The xDrive40e plug-in hybrid promises 85.6mpg and 77g/km CO2, leveraging a 19-mile electric range for urban commutes. Real-world results depend on charging discipline; longer trips revert to hybrid mode around 40-50mpg.

• Diesels: Best for motorways; 45-50mpg achievable.
• Hybrid: Urban star; tax-friendly emissions.
• Petrols: Power-focused; higher fuel bills.

Running Costs and Maintenance Insights

Condition-based servicing optimizes costs, with intervals up to 24 months or 18,000 miles. Diesels prove economical for tax and fuel, especially post-ULEZ zones. Hybrids minimize road tax via low CO2. Insurance groups range 40-50, reflecting performance.

Expect annual servicing around £300-£500 at independents, higher at BMW dealers. Tyres and brakes wear faster on heavier models; budget £800-£1,200 yearly for routine upkeep. Diesel particulate filters (DPF) need regular drives to avoid issues.

CO2-based VED favors efficient models: hybrids under £20/year, diesels £150-£200, petrols £500+. Fuel costs for 10,000 miles/year: diesel ~£1,200, hybrid ~£800 (with charging), petrol ~£2,500 (at £1.50/litre).

Engine Options and Performance Breakdown

The Mk3 X5 offers diverse powertrains:

• 25d (2.0L Diesel): 218hp, 0-62mph in 8.2s, efficient daily driver.
• 30d (3.0L Diesel): 258hp, 6.9s sprint, versatile all-rounder.
• 40d (3.0L Diesel): 313hp, 5.9s, near-M performance.
• M50d (3.0L Quad-Turbo): 381hp, 5.3s, diesel pinnacle.
• xDrive40e (Hybrid): 313hp combined, electric mode for stealthy starts.
• 50i/M (Petrol V8): 455hp+, sub-5s acceleration, thirstiest.

Diesels dominate used stock (90%+), with straight-six reliability praised for smoothness and 11.5L/100km average.

Practicality, Reliability, and Ownership Experience

Spacious cabin fits five comfortably; optional seven seats boost versatility. Boot holds 650L expanding to 1,870L. Ride balances sportiness with comfort via adaptive dampers.

Reliability is solid for diesels, though electronics and turbo issues arise post-100,000 miles. Check for timing chain wear on early models. xDrive system excels in traction.

Owners report high satisfaction with handling and tech, but note firm rides on larger wheels. Fuel economy beats class averages.

Buying Tips for the Savvy Shopper

Inspect service records, DPF health, and battery in hybrids. Test AWD engagement and suspension. Avoid high-mileage petrols without provenance.

• Target 2015+ for refined tech.
• Haggle on ex-fleet diesels.
• Budget for warranty extensions.
