Why this report matters

Thai automotive-aftermarket $7.25-350B annual; ~20M registered vehicles. Cockpit (CKPT, SET-listed), B-Quik (Cofra) major service chains. Bridgestone, Michelin, Yokohama, Continental Thai-plant tyre cluster. PTT Lubricants, Caltex, Castrol lubricant cluster. EV-transition reshaping aftermarket.

Operator playbooks

Cockpit (CKPT, SET-listed) operates ~150 branches and is the Thai-listed pure-play on the tyre-and-service-bay value chain. Its EV-readiness programme centres on technician retraining, high-voltage tooling roll-out, and a tyre-and-brake-led EV-service proposition (since lubricant and transmission work disappears on EVs but tyre, brake and alignment scopes grow). Cockpit's branch-level same-store revenue is a clean public signal of EV-mix shift.

B-Quik (Cofra-affiliated, Marubeni-backed) runs ~150+ branches and competes head-to-head with Cockpit on tyre, fast-fit and battery service. The Marubeni Bquik scope partnership underpins parts-sourcing leverage on global tyre brands and battery suppliers. B-Quik is investing aggressively in EV-charging-station partnerships and high-voltage-certified technicians.

The OEM-dealer aftermarket channel (Toyota, Honda, Isuzu, Mitsubishi, Nissan dealer networks) holds an estimated 30 to 40% of aftermarket-parts revenue under-warranty plus customer-retention service. Chinese EV OEMs (BYD, MG, GWM, NETA) are building dealer-service capacity rapidly; the structural question is whether they can match the 30-year customer-trust footprint Japanese OEMs built on ICE.

Tyre manufacturer cluster (Bridgestone, Michelin, Yokohama, Continental, Maxxis Cheng-Shin, Otani Tyre) operates Thai-plant manufacturing serving export and domestic. Michelin's Klaeng and Laem Chabang plants are the largest by capacity; Bridgestone has the largest Thai distribution and replacement-tyre brand. The tyre segment is structurally insulated from EV transition because EVs accelerate tyre wear rather than eliminate the SKU.

Lubricant cluster (PTT Lubricants, Caltex, Castrol, Shell, Mobil) is the most structurally exposed to EV transition. PTT Lubricants (PTTOR-affiliated) is investing in EV-specific lubricants (thermal management fluid, e-axle gear oil) but the addressable market for those products is a fraction of ICE engine-oil spend.

Tier-1 OE suppliers (Thai Summit Group, Somboon Advance Technology, Aapico Hitech, Thai Stanley Electric, Apex Circuit Thailand) supply Thai vehicle assemblers and increasingly cross-sell aftermarket SKUs via wholesale and retail-chain channels. Apex Circuit and Somboon Advance have established EV-component lines (battery-management PCBs, EV-suspension parts) to defend against ICE-volume decline.

Thailand EV Adoption: BYD-MG Lead and the BEV-Incentive Cycle

Thailand registered 120,301 BEVs in 2025 (+80.3% YoY from 70,137 in 2024) per US-ASEAN Business Council; BEV market share jumped from approximately 14% to 19.4%. BYD holds 38.5% of the Thai BEV market with MG at 12.9%; Chinese brands account for 85% of Thai EV sales. BYD opened its first factory outside China in Rayong (WHA Industrial Estate, 150K annual capacity) on 4 July 2024. The EV 3.0 scheme paid up to THB 150K per BEV; EV 3.5 reduced consumer subsidies to THB 50K-100K with production-obligation ratios of 1:2 (December 2026) and 1:3 (December 2027). The 30@30 policy targets 30% of all vehicles produced in Thailand to be zero-emission by 2030.

The Thai Used-Car Market: Carro, Roddonjai, and the 2023 Resale-Value Collapse

Thailand's used-car market reaches estimated 1.5-2.5M annual transactions worth THB 600-900B aggregate value across organised-and-informal dealer networks. Major organised-dealer operators: Carro Thailand (Singapore-listed parent AUTOPL, US-VC-backed plus Goldman Sachs Asia involvement, largest organised used-car operator), Roddonjai Thailand (Thai-domestic, NS-listed parent), 1Take Auto, Otomaxx, Auto Auctioneer Thailand, Auto Hubs. Informal dealer network ~5,000-8,000 used-car dealers nationwide plus weekend-fair operators. Used-car category split: passenger-car (sedan, SUV, compact), pickup-truck (Toyota Hilux, Isuzu D-Max, Ford Ranger structurally largest used-pickup category), motorcycle. Major 2023-2024 used-car-resale-value collapse: prices declined 20-30% across major categories driven by (a) EV-substitution as Chinese BYD, MG, GWM Ora, Neta entered Thai market with subsidised-pricing depressing ICE-resale-value; (b) parallel-import Japanese-used-car flow (Japanese-domestic-market 6-10 year-old used vehicles imported and resold in Thailand) increasing supply; (c) post-COVID consumer-demand softening. Resale-value collapse broke auto-loan loss-given-default assumptions — Krungsri Auto, Tisco Auto Loan, SrisawadPower auto-loan exposure (sister NPL-cycle and pawn-shop reports). Watch BYD, MG continued EV-substitution and parallel-import flow.

Thailand Tier-1 Auto Supplier EV Transition 2027 Market Intelligence

TAPMA's ~700-strong Thai Tier-1 cohort is being stress-tested by the BOI EV3.5 production-to-import ratio tightening from 1:2 in 2024-2025 to 1:3 by 2027. Aapico Hitech (SET: AH) won a Changan EV-component nomination in May 2024; Thai Stanley Electric (SET: STANLY) is pushing LED headlamps; Somboon Advance (SET: SAT) is hedging pickup axles into e-mobility suspension; Sammitr is building electrified heavy trucks with a Chinese partner. Cockpit and B-Quik dominate the aftermarket pivot to EV-grade tyres, 12V batteries, and charging accessories. Our 2027 thesis: roughly 40% of the cohort survives the next 24 months; survivors capture battery housings, inverter casings, charging cables, LED headlamps, and pickup-EV chassis.
