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.
Fitted exclusively to the V8 Vantage N430, the engine was tuned for enhanced throttle response and track-focused dynamics. It retains the same core architecture as the standard V8 Vantage but with revised intake and exhaust tuning, sport suspension calibration, and a weight-saving package. Emissions compliance is achieved through precise fuel mapping and secondary air injection, meeting Euro 6b standards for its production period.
One documented concern is premature wear of the variable valve timing solenoids, highlighted in Aston Martin Technical Service Bulletin TSB-ENG-019. This issue correlates with extended service intervals and can lead to erratic idle or reduced performance. Revisions to solenoid material and filtration were implemented in 2015, improving long-term reliability in later production units.
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 naturally aspirated V8 provides linear throttle response and high-rpm refinement ideal for spirited driving, but demands strict adherence to 12,000-mile oil change intervals to prevent timing chain and VVT wear. Castrol Edge 5W-50 meeting AM-SPEC-002 is critical due to its high-shear stability protecting the duplex timing chain. Cold starts should be followed by gradual warm-up to ensure oil pressure stabilises before high-load operation. Fuel system longevity depends on regular use of high-octane (98 RON) petrol to prevent injector coking. Post-2015 units feature updated VVT solenoids; pre-2015 engines should be inspected per TSB-ENG-019 for wear indicators.
Oil Specs: Requires Castrol Edge 5W-50 meeting AM-SPEC-002 (Aston Martin SIB 14 03 01). Supersedes ACEA A3/B4.
Emissions: All N430 engines meet Euro 6b standards (VCA Type Approval #VCA/EMS/6123).
Power Ratings: Measured under SAE J1349 standards. Full output requires 98 RON fuel (Aston Martin TIS Doc. N430-PERF-01).

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.
Locate the engine serial number stamped on the right-hand side of the engine block, near the front cylinder bank (Aston Martin TIS N430-ID-01). The 8th VIN digit indicates engine type ('V' for V8). All N430 models feature black cam covers with 'N430' badges. Critical differentiation from standard V8 Vantage: N430 uses Bosch ME7.2 ECU with enhanced calibration and revised intake plenums. Service parts require model-year verification - VVT solenoids for pre-2015 engines are incompatible with post-2015 units due to internal redesign (Aston Martin TSB-ENG-019).
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.
