## Why this model

The Porsche 918 Spyder isn't just a car; it's a piece of automotive history and a serious collector's item. As one of the 'Holy Trinity' of hybrid hypercars, it represents a pinnacle of engineering from its era. It's a phenomenal driving machine, incredibly rare, and has proven to be a strong appreciating asset. You're buying an investment and an unparalleled driving experience, not just transport.

## What you should pay

The 918 Spyder is a hypercar and a collector's item, so its price is not subject to typical depreciation. Instead, values are driven by rarity, condition, mileage, provenance, and the overall collector market. Prices have appreciated significantly since new and are expected to remain strong or continue to climb. Expect to pay a substantial premium for low-mileage, well-documented examples, especially those with the desirable Weissach Package.

## Which trim to buy

While the standard 918 Spyder is already incredible, the Weissach Package is the one to go for if you can find and afford it. It shaves off around 41kg through lighter wheels, magnesium chassis parts, ceramic wheel bearings, and other weight-saving measures. This enhances its already blistering performance and makes it even more desirable to collectors, ensuring stronger value retention and potential appreciation.

## What to check before you buy

- High-voltage battery degradation (expensive replacement)
- Complexity of the hybrid system requiring specialist diagnostics and repair
- Wear and tear on carbon ceramic brakes (extremely costly to replace)
- Specialist active suspension component wear
- Potential software glitches in early complex systems
- Ensure all factory recalls (e.g., wiring harness, suspension components) have been completed

## Running costs

Running a 918 Spyder is incredibly expensive. Insurance will be a specialist hypercar policy, likely £10,000+ annually. Servicing must be done by official Porsche centres or highly reputable hypercar specialists, with annual costs easily ranging from £5,000 to £20,000+, and major services or unexpected repairs potentially running into six figures. Fuel consumption is high when the electric range is depleted, requiring premium unleaded. VED (road tax) will be the premium rate for cars over £40k new: £195/year plus a £390 supplement for 5 years (total £585/year for years 2-6). Tyres are bespoke high-performance items, costing thousands per set and wearing quickly.

## Key stats

- **Fuel Type**: Plug-in Hybrid
- **Horsepower**: 887 hp (combined)
- **Mpg**: 94 mpg (NEDC combined, highly theoretical)
- **Reliability Score**: Generally well-engineered, but complex hypercar systems require specialist, expensive maintenance. Not rated like conventional cars.
- **Safety Rating**: Not crash-tested by Euro NCAP due to its limited production and hypercar status.

## Trim comparison

| Trim | Price new | Price used | Key features |
| --- | --- | --- | --- |
| Standard | £780,000 | £1,750,000 | 4.6L V8 engine with two electric motors; 887 hp combined output; Carbon fibre monocoque chassis |
| Weissach Package | £850,000 | £2,100,000 | All Standard features PLUS:; Lightweight magnesium wheels; Extended carbon fibre interior and exterior components |

## Depreciation forecast

| Year | Estimated value | Retention |
| --- | --- | --- |
| 2026 | £1,850,000 | 100% |
| 2027 | £1,900,000 | 102.7% |
| 2028 | £1,950,000 | 105.4% |
| 2029 | £2,000,000 | 108.1% |
| 2030 | £2,050,000 | 110.8% |

For a Porsche 918 Spyder, the 'sweet spot' isn't about depreciation, as it's an appreciating asset. The sweet spot is finding an example with impeccable provenance, a full Porsche service history, very low mileage, and ideally the Weissach Package. These factors will ensure its value as a collector's item remains strong or continues to grow.

Total value lost since new: -10.8%.

## Alternatives to consider

- McLaren P1
- Ferrari LaFerrari
- Mercedes-AMG Project One (if budget allows for newer)
