Audi’s A3 sedan replaces the A3 hatchback for 2015. (Audi USA/ )

This stunningly beautiful town, bounded by three bodies of water, has been our family’s summer vacation spot for five years. We always drive — choosing a car small enough to easily navigate Newport’s narrow streets, powerful enough to safely get us through the mayhem of Interstate 95, and comfortable enough to hold three people and a large chocolate Labrador jealously protective of her riding space.

Past trips have required compromise in the choice of automobiles. Small often lacked needed power. Powerful enough often proved too large. And because Newport is a stylish place, there always was the matter of the swank factor — a car luxurious enough to fit in, but not so overwhelming in presentation that it reeked of trying too hard.

This year’s driving choice was easy — the compact Audi A3 2.0T Quattro sedan, all new for 2015. The car replaces the A3 hatchback, which had been a pleasure to drive but had the persona of an overpriced economy car.

The cost of the new A3 sedan remains dear for middle-income wallets, starting at $29,900 for the “base” Premium model and moving up to $38,350 for the top-of-the-line A3 Prestige. We happily muddled in the middle with the all-wheel-drive A3 Premium Plus, which has a starting price of $32,900.

It was a good choice. The car came with an optional 2-liter, turbocharged (forced air) in-line four-cylinder gasoline engine that delivered impressive power (220 horsepower, 258 pound-feet of torque) and almost reasonable fuel economy — 24 miles per gallon in the city and 33 on the highway.

I would have called those mileage numbers “good” for a small luxury sedan. But the turbocharged engine requires premium gasoline, which cost as much as $4.22 a gallon when we visited these parts in late July.

But it was a small sacrifice given the nature of the A3 sedan’s remarkable performance. The car was a sheer joy to drive — wonderfully responsive in high-speed highway traffic, easy to maneuver on congested streets.

I would’ve preferred that the A3 used for this journey had also come with a backup camera and blind-side warning system. Those advanced safety technologies would have been useful on some of this town’s streets, packed with cars, bicyclists and pedestrians generated by the recently concluded 2014 Newport Music Festival. But as often is the case with automotive pricing, you have to spend more to get those available safety items.

Still, the A3 remains a pretty good deal for people shopping for luxury on a budget. The car has one of the most well conceived and rendered interiors of any automobile in any class — attractive in its simplicity, outfitted with high-quality materials, ergonomically sensible. It is a good place to be in on a long drive, even with a large dog.

The A3 sedan also is deceptively fast. I write this, almost as an afterthought, because I am remembering the times I looked at the A3’s speedometer and was surprised to find that I was running at 80 mph. I usually “feel” that kind of speed as a car moves against the wind, or “hear” it in terms of a whining or straining engine. But none of those cues were evident in the A3’s smooth, quiet, seemingly effortless performance.

I looked at the speedometer and slowed down, which required moving over to the right lane on I-95. Like it or not, legal or not, going slower than 80 on that highway, especially in the left or middle lanes, is often going too slow. I yielded to substantially faster traffic.

I suffered no loss of ego in conceding to faster drivers. Confidence is knowing you can go faster in response to necessity or will. During a nearly 1,000-mile drive here from our home in Northern Virginia, I developed maximum confidence in the Audi A3 sedan. It is not hyperbole to claim that I fell in love with the little car.

It did everything I wanted it to do exactly when I wanted it to do it. It was a control freak’s motorized dream. Notice to the BMW 2-series, Cadillac ATS, Infiniti G-class sedan and Mercedes-Benz CLA: Your Audi competition has arrived and is quite willing and able to snatch market share.

Nuts & Bolts
2015 Audi A3

Bottom line: The 2015 Audi A3 sedan is one of the best small luxury cars available. Hint: Audi could make this one even more attractive by installing a rearview backup camera and blind-side warning system as standard equipment on all A3 models. That would raise production costs. But here’s betting it also would reduce marketing costs and increase sales.

Ride, acceleration and handling: Good marks in all three. Its all-wheel-drive system inspires driver confidence in foul weather on slippery roads, especially in curves.

Head-turning quotient: The A3 has a stately, attractive exterior that bespeaks affluence with class. The car’s interior is one of the best in the business at any price.

Body style/layout: The sedan is all-new for 2015. It replaces the A3 hatchback and is available in three trim levels — “base” front-wheel-drive Premium; mid-level all-wheel-drive Premium Plus and top-grade Prestige. Soon to be added to the lineup are an A3 convertible, a diesel-fueled A3 and an S3 high-performance model.

Engines/transmission: The 2015 Audi A3 sedan comes standard with a turbocharged 1.8-liter in-line four-cylinder gasoline engine developing 170 horsepower and 200 pound-feet of torque. The 2-liter version in this week’s sample car is available as an option. Both engines transmit power via a six-speed automatic transmission that also can be operated manually.

Capacities: Seating is for five people. Cargo capacity with all seats in place is a scant 10 cubic feet. A fold-down feature in the 60-40 split rear seats allows for carriage of longer items. The fuel tank holds 14.5 gallons of gasoline. Premium-grade fuel is required.

Mileage: I actually averaged 33 miles per gallon on the highway. I’m still shocked.

Safety: Standard equipment includes ventilated front and solid rear disc brakes, four-wheel anti-lock brake protection, emergency braking assistance, and electronic brake-force distribution.

Pricing: The all-wheel-drive 2015 Audi A3 Premium Plus sedan starts at $32,900, with a dealer’s invoice price of $30,598. Price as tested is $37,545, including $3,750 in “upgrades” (Bang & Olufsen premium sound system, 18-inch-diameter wheels, onboard navigation and other items) and a $895 factory-to-dealer transportation charge. Dealer’s price as tested is $34,982.
