The Lotus Type 918 is a 3,500 cc, V6 twin‑turbocharged petrol engine produced between 2013 and 2021. Developed in collaboration with Toyota and tuned by Lotus Engineering, it features a 60‑degree aluminium block, dual overhead camshafts (DOHC), and direct fuel injection. In standard form it delivered 350–400 PS, with torque figures between 400–450 Nm, depending on model application and state of tune.

Production years 2013–2021 meet Euro 6 emissions standards .
The Lotus Type 918 is a 3,500 cc V6 twin‑turbo petrol engine engineered for high‑performance sports cars (2013–2021). It combines direct injection with twin IHI turbochargers and Lotus‑specific calibration to deliver immediate throttle response and robust track capability. Designed to meet Euro 6 standards, it balances emissions control with uncompromised performance.

The Lotus Type 918 was used exclusively in Lotus's Evora platform with mid‑engine longitudinal mounting and no external licensing. This engine received platform-specific adaptations—revised intercoolers and exhaust manifolds in the GT430 and lightweight flywheels in the Sport 410—and from 2017 the facelifted Evora GT adopted updated turbo controls and reinforced hoses, creating minor interchange limits. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.
Analysis derived from Lotus technical bulletins (2015–2021) and UK DVSA MOT failure statistics (2018–2023). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The Type 918 is robust when maintained properly. Early models (2015–2016) require hose upgrades per LTB/18/07, while all versions benefit from strict 10,000 km oil changes and intake cleaning. With correct care, it offers excellent track durability and road reliability. Use 98 RON fuel and OEM-specified oil to maximise longevity.
Intercooler hose cracking, intake valve carbon buildup, turbo bearing wear from poor oil maintenance, and timing chain tensioner wear are the top issues. These are documented in Lotus service bulletins LTB/18/07 and LTB/18/03. Regular inspection and OEM parts mitigate most risks.
The Type 918 powered the Evora 400 (2015–2018), Evora Sport 410 (2016–2019), Evora GT430 (2017–2019), and Evora GT (2019–2021). All are mid-engine, longitudinal V6 applications with twin-turbocharging. It was never used in Elise, Exige, or Emira models.
Aftermarket ECU tuning is common on the TYPE-918 platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
Typical consumption is 12–14 L/100km (20–24 mpg UK) in mixed driving. Track use may exceed 18 L/100km, while gentle road driving can achieve 10.5 L/100km (~27 mpg UK). Economy is secondary to performance in this high-output application.
Yes. The Type 918 is an interference design—valves and pistons occupy shared space if timing is lost. A failed timing chain can cause catastrophic internal damage. Regular inspection of the chain and tensioner is essential, especially after 60,000 km.
Lotus specifies SAE 5W-40 full synthetic oil meeting ACEA C3 standards (e.g., BMW LL-04, MB 229.31). Change every 10,000 km or annually. This protects turbo bearings, timing components, and meets emissions system requirements.
