Engine Database
Every powertrain fitted to the G60 specifically — including 48V mild-hybrid petrol and diesel engines, plug-in hybrids, and the all-electric i5 range.
Overview
The G60 is the eighth generation of the BMW 5 Series, an executive saloon that began production in July 2023. Built on an updated version of the rear-wheel drive Cluster Architecture (CLAR) platform, shared with the larger G70 7 Series, it is significantly larger than its predecessor. Designed by Anders Thøgersen, the G60 introduces a bold new design language with a distinctive front grille and flush door handles.
The engine line‑up is the most diverse in 5 Series history: 48V mild-hybrid four- and six-cylinder petrol and diesel engines, plug-in hybrids (530e, 550e xDrive, M560e xDrive), and the fully electric i5 range (eDrive40, xDrive40, M60 xDrive). The G60 is the last 5 Series generation to feature pure internal combustion engines, with the M560e effectively replacing the V8-powered M550i.
Key Facts
Market Intelligence
The 5 Series nameplate generated significant UK engine enquiries in 2025 [BMW-VERIFIED], with demand for the G60 concentrated on the 520d diesel and 530e plug-in hybrid based on market patterns.
04Best & Worst Engines
Best Value
B48B20O1 (530i)
“The B48 four-cylinder delivers 258 bhp — more than enough for everyday driving — with excellent fuel economy and lower running costs than the six-cylinder. In the G60's lightweight CLAR platform, it's a genuinely capable executive saloon.”
Who it's for: buyers who want modern performance with sensible running costs.
Most Overlooked
B57D30 (540d xDrive)
“The six-cylinder diesel is often overlooked in favour of the 530e or 540i, but it delivers 305 bhp of effortless torque with genuine 40+ mpg economy. It's the thinking buyer's choice — refined, powerful, and efficient.”
Who it's for: buyers who want six-cylinder refinement with diesel economy.

The G60 rule
A £4,500–£7,000 B58 recon against a £35,000–£55,000 540i sits at 8–20% of the car's value -well within our 70% BMW scrap threshold. For a 530e at £40,000–£50,000, a £4,000–£6,500 recon is 8–16% -a straightforward repair decision. These are high-value cars; the replacement cost is a manageable proportion of the vehicle's worth. But beware of battery degradation on PHEV and EV models -a battery replacement can cost £10,000+. Value the car and its battery health first; if it's a high-mileage PHEV without battery history, budget for potential degradation.
Key Takeaways
Which G60 Costs Least To Own?
520d (B47D20B) -proven diesel efficiency, low CO2, strong economy.
Which G60 Costs Most To Own?
M560e xDrive (B58B30S) -complex PHEV system, expensive parts, high performance = high running costs.
Which G60 Is Best Value?
530i (B48B20O1) -modern four-cylinder, strong performance, lower running costs than six-cylinder.
B58
Cooling System & PCV Valve (540i, 550e, M560e)
Affected models:
Typical failure mileage:
Root cause:
Our Recommendation
Have the cooling system and PCV valve inspected at every major service -a £400–£1,000 preventative repair is cheaper than the £4,500+ replacement that follows a catastrophic failure. On a £40,000+ car, this is a manageable cost of ownership.
B47/B57
Diesel EGR Cooler & DPF (520d, 540d)
Affected models:
Typical failure mileage:
Root cause:
Our Recommendation
If you're buying a diesel G60 for urban use, budget for DPF maintenance -£400–£1,200 for a clean or EGR cooler replacement is cheaper than the £3,000+ replacement that follows a catastrophic failure. Motorway driving helps keep the DPF clear.
PHEV
Battery Degradation (530e, 550e, M560e)
Affected models:
Typical failure mileage:
Root cause:
Our Recommendation
If you're buying a used G60 PHEV, check the battery's state of health -a battery with significant degradation will reduce the car's value and increase running costs. Budget for potential battery replacement if you plan to keep the car long-term. On a £40,000+ car, a £6,000–£10,000 battery replacement is a serious but manageable cost.
i5
Battery & Cooling System (All i5 Models)
Affected models:
Typical failure mileage:
Root cause:
Our Recommendation
If you're buying an i5, ensure the battery cooling system has been serviced and the battery's state of health is verified. On a £50,000+ car, a £7,000–£12,000 battery replacement is a significant but manageable cost -but it's one you should budget for if keeping the car beyond the 8-year warranty period.
