McLaren 650S: A Comprehensive Guide

The McLaren 650S, a successor to the MP4-12C, represents a significant evolution in McLaren's supercar lineup. Introduced in 2014 and produced until 2017, it slots into the high-performance supercar class, competing with vehicles like the Ferrari 458 Italia/488 GTB, Lamborghini Huracan, and Porsche 911 Turbo S. It aimed to blend the raw performance of its predecessor with increased refinement and a more visually appealing design.

Generations

The 650S had a relatively short production run, but within that time, several key variations and model years existed. Key features included:

  • 2014-2017 (McLaren 650S Coupe and Spider): The initial release. Key changes focused on improved aerodynamics, increased power output (641 bhp, hence the 650 designation - metric horsepower), and refined suspension. The design heavily borrowed from the McLaren P1 hypercar, particularly in the front fascia. Both Coupe and Spider (convertible) versions were offered.
  • 2015 McLaren 650S Le Mans: A limited edition (50 examples) Coupe built to commemorate McLaren's 1995 victory at the 24 Hours of Le Mans. Featured unique styling cues, including a roof-mounted snorkel intake, bespoke wheels, and interior trim.
  • 2016 McLaren 675LT (Longtail) Coupe and Spider: While technically a separate model, the 675LT is a direct evolution of the 650S and therefore relevant. It received significant weight reduction, increased power (666 bhp), enhanced aerodynamics (including a larger rear wing), and a track-focused suspension setup. This is widely regarded as a more desirable and hardcore variant of the 650S.

Reliability & Common Issues

The McLaren 650S, while a high-performance machine, has its share of potential reliability concerns. Potential buyers should be aware of the following:

Engine

  • Oil Leaks: The twin-turbocharged 3.8L V8 engine can be prone to oil leaks, particularly around the camshaft covers and turbocharger oil lines. Thorough inspection is critical.
  • Turbocharger Issues: Turbochargers can fail, especially in cars that have been heavily tracked or improperly maintained. Listen for unusual noises during boost and check for signs of oil leakage in the intake system.
  • Cooling System: The complex cooling system can develop leaks, leading to overheating. Check coolant levels regularly and inspect hoses and radiators for signs of damage.
  • Carbon Build-up: Direct injection engines are susceptible to carbon build-up on the intake valves. This can reduce performance and fuel economy over time. Walnut blasting or similar cleaning procedures may be necessary.

Transmission

  • Transmission Jerkiness: The dual-clutch transmission (DCT) can exhibit jerkiness, particularly at low speeds and during cold starts. Software updates can sometimes mitigate this issue. Consider a transmission flush as part of the due diligence.
  • Clutch Wear: The clutches in the DCT will eventually wear out, especially with aggressive driving. A clutch wear test should be performed during a pre-purchase inspection.

Electronics

  • Sensor Failures: Various sensors, including those related to the suspension, engine management, and stability control systems, can fail. Diagnostic scans are essential.
  • IRIS Infotainment System: The IRIS infotainment system can be buggy and slow. Software updates can improve its functionality, but it's still considered a weak point.
  • Battery Drain: Battery drain issues can occur, particularly in cars that are not driven regularly. A battery tender is recommended.

Suspension

  • Accumulator Issues: The hydraulic suspension system relies on accumulators, which can leak or fail over time, resulting in reduced ride quality and handling performance.
  • Suspension Component Wear: Bushings, ball joints, and other suspension components can wear out, leading to sloppy handling.

Driving Experience

The McLaren 650S offers an exhilarating driving experience. Here's a breakdown of the pros and cons:

Pros:

  • Blistering Performance: The twin-turbo V8 delivers explosive acceleration and a thrilling top speed.
  • Sharp Handling: The lightweight carbon fiber chassis and sophisticated suspension provide exceptional handling and cornering grip.
  • Responsive Steering: The hydraulic steering system offers excellent feedback and precision.
  • Exotic Styling: The 650S is a visually stunning car that turns heads wherever it goes.
  • Relatively Comfortable: For a supercar, the 650S offers a surprisingly comfortable ride, thanks to its adaptive suspension.

Cons:

  • Maintenance Costs: Supercar maintenance can be expensive, particularly when dealing with specialized components and labor.
  • Limited Practicality: The 650S is not a practical car for everyday use, due to its low ground clearance, limited storage space, and stiff ride (especially in Track mode).
  • Infotainment System: The IRIS infotainment system is outdated and not user-friendly.
  • Potential Reliability Issues: As outlined above, the 650S can be prone to certain reliability problems.
  • Visibility: Rear visibility can be limited.

Buying Advice

If you're considering purchasing a McLaren 650S, here's some advice:

  • Pre-Purchase Inspection (PPI): A comprehensive PPI by a qualified McLaren technician is absolutely essential. This should include a thorough inspection of the engine, transmission, suspension, brakes, and electronics. Compression test and bore scope are highly recommended.
  • Service History: Review the service history carefully to ensure that the car has been properly maintained. Look for evidence of regular oil changes, fluid flushes, and other preventative maintenance.
  • Model Year: While all 650S models offer impressive performance, later production years (2016-2017) may benefit from minor improvements and updates.
  • 675LT vs. 650S: If your budget allows, consider the 675LT. It's a more focused and desirable model with improved performance and handling. However, they are also more expensive.
  • Check for Modifications: Be wary of heavily modified cars, as these can be more prone to reliability issues.
  • Negotiate Wisely: Be prepared to negotiate, as the 650S has depreciated since its initial release. Factor in the cost of potential repairs and maintenance when making an offer.
  • Consider Extended Warranty: If possible, consider purchasing an extended warranty to protect yourself from unexpected repair costs. However, make sure you understand the terms and conditions of the warranty carefully.
  • Test Drive: A thorough test drive is crucial. Pay attention to the engine performance, transmission smoothness, suspension feel, and overall handling. Listen for any unusual noises or vibrations.
