As an automotive enthusiast and lead author for Car News, I’ve had the privilege of driving and reviewing countless vehicles over the past decade. I understand the allure of the 2013 BMW 650i Gran Coupe – a stunning blend of performance, luxury, and style. However, like any car, especially one with such sophisticated engineering, it’s crucial to understand its potential weaknesses before making a decision.
The N63 Engine: Addressing the Concerns
The heart of the matter lies in the 650i’s engine, specifically the N63 twin-turbocharged V8. Early iterations of this engine (pre-2013) were indeed plagued with reliability issues. However, BMW addressed many of these problems with the introduction of the updated N63TU (Technical Update) engine in 2013.
Identifying the N63TU is straightforward:
- Coolant Cap Location: The easiest telltale sign is the coolant filler cap’s position. In the older N63, it’s located on the driver’s side fender near the front of the engine bay. The N63TU relocates the cap to the far back driver’s side corner, close to the firewall.
N63TU Reliability: A More Robust Powerplant
Based on my research and countless forum threads, the N63TU represents a significant step forward in reliability. While no engine is entirely immune to issues, the N63TU seems to have addressed many of its predecessor’s common problems.
That said, it’s crucial to remember that this is still a complex engine in an equally complex car. Regular maintenance by specialized technicians is non-negotiable.
“The N63TU is a different beast altogether,” says Alex Miller, a veteran BMW technician I spoke with. “While I wouldn’t call it bulletproof, it’s a far more reliable engine than its predecessor, especially with meticulous maintenance.”
Weighing the Risks and Rewards
Purchasing a pre-owned 650i Gran Coupe, especially one with the N63TU engine, comes down to your risk tolerance. You’re acquiring a high-value vehicle at a significant discount. While the N63TU is more dependable, unexpected repairs can be costly.
Before taking the plunge, ask yourself these questions:
- Can I comfortably afford potential repairs?
- Am I willing to invest in preventative maintenance from specialized technicians?
The 2013 BMW 650i Gran Coupe: A Calculated Decision
The 2013 BMW 650i Gran Coupe is a captivating car. The N63TU engine, while more reliable, still requires careful consideration. By understanding the potential risks and rewards, and being prepared for the responsibilities of owning such a car, you can make an informed decision and potentially enjoy a fantastic driving experience.
