Used 2018 Audi A3 Convertible Trims Comparison

Front-wheel-drive A3 models have a turbocharged 2.0-liter four-cylinder engine (186 horsepower, 221 pound-feet of torque) and a seven-speed, dual-clutch automatic transmission. These models have a fuel economy edge over their all-wheel-drive siblings to the tune of 2 mpg (EPA combined). All-wheel-drive variants (Quattro) have a similar engine, but a few changes elevate its gumption to a more robust 220 hp and 258 lb-ft. Perhaps paradoxically, Quattro variants have one fewer gear in their dual-clutch automatic transmissions than do front-wheel-drive models. Despite this and their inevitably heavier weights (160 pounds for sedans; 200 pounds for convertibles), Quattro models handily out-accelerate their front-wheel-drive counterparts. No manual gearbox is available on any flavor of A3.

The base Premium is well-equipped, sporting features such as leather upholstery, a backup camera, dual-zone climate control, a panoramic sunroof, forward collision warning and automatic emergency braking, a 10-speaker sound system, heated front seats and an eight-way power driver seat with power lumbar adjustment. Cabriolet models are similar but have a power-folding soft top, a nine-speaker sound system and six-way power front seats with lumbar support.

For a reasonable sum, Premium Plus adds a mix of cosmetics and worthwhile convenience features such as 18-inch wheels, an eight-way power passenger seat with lumbar support, blind-spot monitoring with rear cross-traffic alert, keyless ignition and entry, parking sensors, and Apple CarPlay and Android Auto smartphone integration. These models also gain exterior appearance items such as revised bumpers, side sill extensions and illuminated aluminum front doorsills.

Prestige goes all out with power-folding mirrors, LED headlights, an expanded Virtual Cockpit instrument cluster, navigation, a Bang & Olufsen premium audio system and a host of driver assistance features (including lane departure warning, adaptive cruise, automatic high beams).

Some of the features found on the Premium Plus and Prestige can be added to the lower trims as options. An optional Sport package is available on all three trims; it adds a sport steering wheel with wheel-mounted shift paddles, sport front seats with extendable thigh support and selectable driving modes. A sport-tuned suspension is optional with the Sport package selected.
