The 2021 TLX (third generation, type UB) splits into two very different cars by trim, and that split is the decode that matters. Every trim except Type S — Standard, Technology, and A-Spec — uses the 2.0L K20C turbocharged four-cylinder (272 hp) with a 10-speed automatic; front-wheel drive is standard and Acura’s SH-AWD is optional. The Type S uses an exclusive 3.0L turbocharged V6 (355 hp) with SH-AWD and Brembo front brakes standard. Because the engine tracks the trim, confirm the badge and then verify with a full VIN decode at vpic.nhtsa.dot.gov before applying this checklist: a Type S carries a higher maintenance and tire budget and should have its turbo V6 boost delivery tested across all gears, while a 2.0T car is the lower-cost, lower-risk choice. Position 10 of the VIN encodes the model year (M = 2021). On either engine, confirm the early Google-based infotainment received its software updates and that any SH-AWD car has rear-coupling fluid-service records. Run the full VIN at nhtsa.gov to confirm recall history before purchase.
