BMW X5 4.8is Review: Specs, 0-60, Ownership Costs
Discover why the BMW X5 4.8is delivers thrilling power, refined luxury, and practical versatility in a high-performance package.
The BMW X5 4.8is stands as a pinnacle of early 2000s luxury performance SUVs, combining a potent V8 engine with the practicality of a crossover. Introduced in 2004, this model elevated the X5 lineup by offering sports car-like acceleration while maintaining family-friendly space and off-road prowess. Its naturally aspirated 4.8-liter V8 produces 355 horsepower and 369 lb-ft of torque, propelling the SUV from 0-60 mph in under 6 seconds—a remarkable feat for its era.
Powertrain Excellence: The Heart of the Beast
At the core of the X5 4.8is is its robust 4.8-liter V8 engine, a hallmark of BMW’s N62 series. This all-aluminum powerplant delivers smooth, linear power with a distinctive growl under hard acceleration. Paired with a six-speed automatic transmission and BMW’s xDrive all-wheel-drive system, it ensures seamless power delivery to all wheels, enhancing traction in diverse conditions.
- Engine Specs: 4.8L V8, 355 hp @ 6,200 rpm, 369 lb-ft @ 3,500 rpm
- Transmission: 6-speed automatic with Steptronic manual mode
- Drivetrain: xDrive AWD for superior grip
- Top Speed: Electronically limited to 155 mph
Owners praise the engine’s responsiveness, noting its ability to surge forward effortlessly on highways or twisty roads. Fuel economy hovers around 14 mpg city and 20 mpg highway, typical for a high-performance V8 SUV of this size.
Dynamic Handling and Ride Quality
The X5 4.8is features a sport-tuned suspension with adaptive dampers, larger anti-roll bars, and 20-inch alloy wheels wrapped in performance tires. This setup transforms the X5 from a capable off-roader into a corner-carving machine. Despite its 4,900-pound curb weight, the SUV corners flat with minimal body roll, thanks to BMW’s precise steering and balanced chassis.
| Aspect | X5 4.8is | Standard X5 |
|---|---|---|
| Suspension | Sport-tuned with EDC | Standard comfort setup |
| Wheels/Tires | 20-inch alloys, 275/40R20 | 18-inch standard |
| Brakes | 14.7-inch front vented discs | 13.7-inch standard |
| 0-60 mph | 5.8 seconds | 7.5 seconds (3.0i) |
Braking performance is equally impressive, with massive ventilated discs providing confident stops from high speeds. The electronic stability control allows for playful dynamics without compromising safety.
Luxurious Interior and Practicality
Step inside the X5 4.8is, and you’re greeted by a premium cabin crafted with high-quality leather, wood trim, and metallic accents. The sport seats offer exceptional bolstering and 12-way power adjustments, ensuring comfort on long drives. Rear seating accommodates three adults comfortably, with 54 cubic feet of cargo space behind the second row—expandable to 71 cubic feet with seats folded.
- Climate control with dual-zone automatic settings
- Premium Nevada leather upholstery
- Navigation system with 8.8-inch display
- Harman Kardon audio with 12 speakers
Visibility is excellent, aided by large glass areas and optional rearview camera. While technology feels dated by modern standards, the analog gauges and physical controls provide an engaging, tactile experience.
Off-Road Capabilities and Versatility
Don’t let the performance focus fool you—the X5 4.8is retains BMW’s xDrive system, complete with hill descent control and low-range gearing. Ground clearance of 8.3 inches allows light off-road adventures, while the locking center differential distributes torque optimally. It’s a true dual-purpose vehicle, equally at home on gravel trails or paved racetracks.
Ownership Experience: Costs and Reliability
Purchasing a used X5 4.8is today offers tremendous value, with prices ranging from $8,000 to $15,000 depending on mileage and condition. Maintenance costs are higher due to the V8, but parts availability remains strong. Common issues include valve stem seal wear and coolant pipe failures, addressable with proactive servicing.
- Pros: Thrilling performance, luxurious interior, AWD versatility
- Cons: Thirsty engine, potential repair costs, aging tech
Reliability ratings are average for the segment, with proper care yielding 150,000+ miles of service. BMW’s VANOS system and rod bearings require attention around 100,000 miles.
Comparing the 4.8is to Modern Rivals
Against today’s BMW X5 xDrive40i (375 hp inline-six with mild-hybrid assist), the 4.8is holds its own in raw character. The modern model offers 23/27 mpg and iDrive 8, but lacks the V8’s soulful roar. Porsche Cayenne Turbo and Mercedes ML55 AMG were contemporaries, yet the X5 balances sportiness and usability best.
| Model | Horsepower | 0-60 mph | Price (Used) |
|---|---|---|---|
| X5 4.8is | 355 | 5.8s | $10k avg |
| 2024 X5 40i | 375 | 5.3s | $70k new |
| Cayenne Turbo (2004) | 450 | 5.0s | $12k avg |

Technology and Safety Features
For 2004, the 4.8is packed advanced tech: stability control, six airbags, ABS, and optional adaptive cruise. The iDrive system, though polarizing, centralized controls effectively. Modern upgrades like Bluetooth retrofits enhance usability without sacrificing originality.
Customization and Aftermarket Potential
Enthusiasts love the X5 4.8is for tuning. ECU flashes add 50+ hp, while exhaust and intake mods amplify the V8 symphony. Dinan and AC Schnitzer offer suspension kits for even sharper handling.
