CG Says: The 2021 Audi A4 gains horsepower and drops its base front-wheel-drive model. All A4s now have all-wheel drive. The base engine formerly used on the front-wheel-drive A4 sees horsepower rise from 188 to 201 and is labelled 40 TFSI. The step-up TFSI 45 engine formerly powered the all-wheel-drive A4 and has horsepower increased from 248 to 261. Both engines now have a mild hybrid system.

The A4 is a premium compact sedan that was redesigned for 2017 and is powered by a turbo 2.0-liter 4-cylinder engine. A 7-speed automated-manual is the sole transmission. The performance S4 is powered by a 349-horsepower turbocharged 3.0-liter V6 paired with an 8-speed automatic transmission and standard all-wheel drive.

Notable standard features include a forward collision mitigation system with automatic braking, leather upholstery, sunroof, heated mirrors, LED ambient interior lighting, rearview camera, Bluetooth connectivity, and Apple CarPlay and Android Auto functionality.

Options include Audi’s “Virtual Cockpit” digital gauge cluster, Google Earth satellite navigation display, adaptive cruise control, adaptive suspension, a rear collision mitigation system, blind-spot monitoring, lane departure warning and intervention, rear cross-traffic alert, and traffic-sign recognition.

A dazzling-yet-understated interior and a long list of cutting-edge technology features are chief among the A4’s highlights. Plus, the A4’s sticker prices and standard-equipment lists compare very favorably with its traditional BMW and Mercedes-Benz competitors. If you’re looking for a well-rounded premium compact sedan, the A4 should be on your list.
