Engine overview: electric motor
The e-2008’s electric powertrain features a permanent magnet synchronous motor producing instant torque delivery. This zero-emissions solution incorporates a 50 kWh lithium-ion battery pack providing approximately 200 miles of real-world range. The electric motor configuration eliminates traditional transmission components, utilising a single-speed reduction gear for optimal efficiency. No fuel injection system is required, as the motor operates purely on electrical energy stored in the battery pack.
The electric system requires specific maintenance protocols, particularly regarding the battery management system.
Pros
- Zero local emissions for environmental benefits
- Instant torque delivery for responsive acceleration
- Minimal maintenance requirements
- Silent operation enhances cabin refinement
- Government incentives reduce running costs
Cons
- Limited charging infrastructure in rural areas
- Higher initial purchase cost
- Range anxiety on longer journeys
- Battery replacement costs remain high
Maintenance cost
| Engine | Recommended Interval | Estimated Cost | Cost per 10,000 miles |
|---|---|---|---|
| 1.2 PureTech | 12,500 miles | £180-220 | £160 |
| 1.5 BlueHDi | 15,000 miles | £220-280 | £173 |
| Electric Motor | 25,000 miles | £80-120 | £40 |
Engine sound and character
The 1.2 PureTech engines deliver a distinctive three-cylinder thrum that becomes more refined as engine speed increases. Under acceleration, these units produce a purposeful growl that communicates performance intent without becoming intrusive. The diesel BlueHDi variants offer the characteristic diesel clatter at idle, though modern refinement techniques ensure cabin noise remains acceptable during cruising.
Electric motor operation provides whisper-quiet progress, with only wind and tyre noise audible at highway speeds. The instant torque delivery creates a unique driving character that feels both futuristic and engaging.
Professional tip: Regular engine oil changes using manufacturer-specified grades will maintain optimal engine sound characteristics and prevent premature wear.
Who each engine is best for
| Engine | Best For |
|---|---|
| 1.2 PureTech 100 | Budget-conscious owners, urban commuters |
| 1.2 PureTech 130 | Daily commuters, balanced performance seekers |
| 1.2 PureTech 155 | Performance enthusiasts, motorway drivers |
| 1.5 BlueHDi 100 | Long-distance drivers, economy-focused owners |
| 1.5 BlueHDi 120 | Business users, high-mileage drivers |
