Get a normally aspirated petrol car for simplicity. Get one with cam chain not wet belt system
Many modern vehicles use timing chains instead of wet timing belts (belt-in-oil systems) due to the durability and lower maintenance requirements of chains. Timing chains are made of metal, typically last the life of the engine with proper maintenance, and are lubricated by engine oil within a sealed environment. Wet belts, while also lubricated by oil, are rubber-based and have faced criticism for premature wear and complex replacement procedures in some models.Below is a list of modern vehicles (post-2010 models, focusing on 2020 and newer where possible) that are known to use timing chains instead of wet belts or traditional timing belts, based on available information. Note that engine configurations vary by market, model year, and specific engine type, so always consult the vehicle’s owner’s manual or a trusted mechanic to confirm. I’ve prioritized manufacturers and models commonly associated with timing chains and excluded those known to use wet belts (e.g., certain Ford EcoBoost, Peugeot/Citroën PureTech, or VW TSI engines).Manufacturers and Models with Timing ChainsThe following brands and models are known to use timing chains in many of their engines, particularly in petrol (gasoline) and diesel variants, as of recent model years:ToyotaToyota is renowned for using timing chains in most of its modern engines, especially in petrol models, which are designed to be maintenance-free for the engine’s life.Corolla (1.8L, 2.0L petrol, hybrid engines;

e.g., 2020–2025)VW Tiguan (2.0L TSI; e.g., 2020–2025)Audi A4/A5 (2.0L TFSI, 40 TFSI; e.g., 2020–2025)Audi Q5 (2.0L TFSI; e.g., 2020–2025)Audi RS3 (2.5L inline-5; e.g., 2020–2025) Note: VW’s smaller engines (e.g., 1.0L, 1.5L TSI EA211) often use belts or wet belts, so avoid these for chain preference.Other Notable BrandsLexus: Most models (e.g., IS, RX, NX with 2.0L turbo, 3.5L V6, or hybrid engines; 2020–2025) use timing chains, aligning with Toyota’s approach.Suzuki: Small engines like 1.0L BoosterJet, 1.2L, 1.4L turbo petrol (e.g., Vitara, SX4; 2020–2025) use chains.Jaguar/Land Rover: Diesel models (e.g., 2.0L Ingenium in Range Rover Evoque, Jaguar XE; 2020–2025) often use chains, as do petrol V6/V8 engines.Chevrolet/GM: Larger engines (e.g., 3.6L V6 in Camaro, Cadillac XT5; 2.0L turbo in Equinox; 2020–2025) typically use chains, but smaller engines (e.g., 1.2L in Trax) may use wet belts.Key ConsiderationsHow to Confirm: Check the owner’s manual or look under the bonnet. A plastic cover on the engine suggests a timing belt (dry), while a sealed metal cover indicates a timing chain or wet belt. For wet belts, you’ll need to consult specific engine data, as they’re internal.Maintenance: Timing chains require regular oil changes with manufacturer-specified oil to prevent wear on chains, guides, or tensioners. Neglect can lead to rattling or failure, though this is rare in well-maintained engines.Interference Engines: Most modern engines are interference designs, meaning a chain or belt failure can cause catastrophic damage (valves hitting pistons). Chains are less likely to snap but can stretch if poorly maintained.Wet Belt Issues: Wet belts, used in engines like Ford’s 1.0L EcoBoost or VW’s 1.2L TSI, are prone to degradation if improper oil is used or maintenance is skipped, leading to oil pump blockages. Chains avoid this issue.Regional Variations: Engine setups differ by market (e.g., Europe vs. North America). For example, a VW Polo may have a chain in one region (post-2009) but a belt in another.Manufacturers Known for Wet Belts (Avoid for Chain Preference)These brands use wet belts in some modern engines, so double-check specific models:Ford: EcoBoost (1.0L, 1.5L, 2.0L) and EcoBlue diesel engines (e.g., Fiesta, Focus, Transit Connect).Peugeot/Citroën: 1.2L PureTech petrol (e.g., Peugeot 208, Citroën C3, Vauxhall Grandland X).Volkswagen/Audi: Some TSI engines (e.g., 1.0L, 1.2L, 1.5L EA211 in Polo, Golf, Audi A1).Vauxhall/Opel: 1.2L petrol engines in models like Corsa, Astra (shared with PSA Group).RecommendationsIf you prioritize timing chains for their longevity and lower maintenance, focus on:Toyota, Honda, Subaru, Mazda: Reliable, chain-driven petrol engines with strong reputations for durability.BMW, Mercedes-Benz: Higher-end models with chains, but ensure regular oil changes to avoid chain wear.Hyundai/Kia, Nissan: Good options for affordable chain-driven vehicles, especially in mid-size or larger models.Larger Engines: Engines above 1.8L (e.g., 2.0L TSI, 3.5L V6) are more likely to use chains due to higher torque demands.Final NotesThis list is not exhaustive, as manufacturers may change engine designs across model years or markets. For example, a 2020 VW Golf 1.0L TSI may have a wet belt, while the 2.0L TSI in the GTI uses a chain. Always verify the engine code (e.g., EA888 for VW/Audi chains) and consult a mechanic or the manufacturer’s service data. If you provide a specific make, model, year, and engine size, I can narrow it down further.If you’re shopping for a vehicle, consider checking sites like Honest John () or FixMyCar () for detailed lists of chain- vs. belt-driven models. Regular maintenance, especially oil changes every 6,000–10,000 miles with the correct oil spec, is critical for timing chain longevity.
