The Aston Martin N430 is a 4,735 cc, V8 petrol engine produced between 2014 and 2016. It features a naturally aspirated 32 — valve DOHC configuration with variable valve timing, delivering 386 kW (525 PS) and 600 Nm of torque. This engine provides smooth, linear power delivery characteristic of high — end grand tourers, with a focus on acoustic refinement and driver engagement.

All N430 engines comply with Euro 6b emissions standards (VCA UK Type Approval #VCA/EMS/6123), with full certification for UK and EU markets.
The Aston Martin N430 is a 4,735 cc V8 naturally aspirated petrol engine engineered for high-performance grand touring applications (2014–2016). It combines DOHC 32-valve architecture with variable valve timing to deliver linear power and high-rpm refinement. Designed to meet Euro 6b, it balances performance with emissions compliance.

The Aston Martin N430 was used exclusively in the V8 Vantage N430 with rear-mounted longitudinal orientation and no licensed external applications. This engine received model-specific tuning-aggressive throttle mapping and free-flow exhaust tuning-and was paired with a sport suspension and lightweight components. All adaptations are documented in OEM technical bulletins.
The N430's primary reliability risk is variable valve timing solenoid degradation in early builds, with elevated incidence in vehicles with irregular maintenance. Internal Aston Martin quality reports from 2016 indicated a notable number of pre-2015 engines requiring solenoid replacement before 60,000 miles, while VCA records show related misfire and limp-mode faults in non-serviced vehicles. Extended service intervals and low-quality oil increase wear risk, making oil quality and interval adherence critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The N430 offers refined performance but early models (2014–2015) are prone to VVT solenoid issues if maintenance is delayed. Post-2015 revisions significantly improved durability. With strict adherence to oil change intervals (every 12,000 miles) and use of Castrol Edge 5W-50, well-maintained examples can exceed 100,000 miles reliably.
Key issues include VVT solenoid failure (especially pre-2015), intake manifold flap cracking, coolant leaks from thermostat housing, and valve cover oil seepage. These are documented in Aston Martin service bulletins and affect long-term ownership costs if not proactively addressed.
The N430 was used exclusively in the V8 Vantage N430 (2014–2016) in both coupe and roadster forms. It is a naturally aspirated V8 with enhanced tuning and lightweight components. All units meet Euro 6b emissions standards.
Limited tuning potential exists via ECU remapping, typically yielding +20–30 kW. However, the naturally aspirated design and high compression limit gains. Supporting mods like exhaust and cam upgrades are costly. Most owners prioritise reliability over power increases due to engine complexity and value preservation.
Moderate for a naturally aspirated V8 GT. In V8 Vantage N430 form, expect ~17 mpg UK (16.5 L/100km) combined. Highway cruising can achieve ~21 mpg UK, while city driving may drop to 13 mpg UK. Real-world consumption depends heavily on driving style. Requires 98 RON premium petrol for optimal performance.
Yes. The N430 is an interference engine. If the timing chain fails, pistons will contact open valves, resulting in catastrophic engine damage. Regular inspection of the duplex chain and tensioners per TSB-ENG-019 is essential to prevent costly repairs.
Aston Martin specifies Castrol Edge 5W-50 meeting AM-SPEC-002. This high-shear-stability oil is critical for protecting the timing chain and VVT system. Change every 12,000 miles or annually, whichever comes first, to maintain engine longevity and prevent wear.
