The 221-hp 2.0L inline-4 engine of the 2021 GLA combines turbocharging with numerous advances to deliver more power from less fuel. Its rapid-multispark ignition and high-pressure Direct Injection can fine-tune themselves in milliseconds. Its twin-scroll turbo and CAMTRONIC variable valve lift help keep all 258 lb-ft of torque on tap from just 1,800 rpm. Clever CONICSHAPE cylinders slash friction to help reduce wear and fuel consumption. And a particulate filter helps make its emissions even cleaner.
An ECO Start/Stop system automatically shuts off the engine at stoplights and other idle situations, to save fuel and reduce emissions. As soon as the driver lifts off the brake, the engine instantly restarts, for immediate acceleration response. The ECO Start/Stop system can also be shut off by the driver at any time.
The new 8-speed transmission combines the sporty response of a manual, the easygoing refinement of an automatic, and exceptional efficiency. Dual clutches offer quicker gear changes than a human can shift a traditional manual gearbox, while three overdrive ratios boost highway efficiency. The ECO, Sport and Comfort modes of DYNAMIC SELECT let you favor fully automatic efficiency and comfort, intensified response, or shift-for-yourself excitement via the steering wheel-mounted shift paddles.
The GLA front-wheel drive system is an ideal match for its nimble handling and efficient packaging. Impeccable calibration of the Electronic Stability Program (ESP®) and Electronic Traction System (ETS) enhances tire bite under hard acceleration, while equal-length driveshafts virtually eliminate undesirable torque steer.
