2013 Audi A4 Review

Even though the current version of the Audi A4 first hit dealerships all the way back in fall 2008, periodic updates make the 2013 A4 a lot more competitive than its vintage would suggest. It's a textbook example of how an automaker can keep an older model fresh.

BMW's redesigned 3 Series will hold on to the perennial sport-sedan spotlight, but the 2013 Audi A4 is an unfairly overlooked competitor.

Chief among the updates for 2013 are revisions to the car's face, including redesigned headlights, and some functional changes inside (compare the 2013 and 2012 A4 here).

The A4 now comes only as a sedan with a turbocharged four-cylinder engine; the related S4 has a supercharged V-6. Audi replaced the A4 Avant wagon by resurrecting the Allroad nameplate — essentially an A4 Avant with better off-road chops. Read my review of the Allroadhere, or compare the A4 and S4 here. This review focuses on the A4, which comes with front- or all-wheel drive and a manual or automatic transmission. Compare them here.

Mite-Sized, but Mighty

The A4 puts Audi's knack for turbo four-cylinder engines on display and goes to show that horsepower is only one part of the performance equation. The A4's tiny, 2.0-liter four-cylinder and its 211 hp rating may seem meager, but a robust 258 pounds-feet oftorque coming as low as 1,500 rpm mean the car scoots. I could leave our test car's six-speed manual in 5th or 6th gear and hum along at 40 mph with enough power to ramp up speed as needed. Stand on the gas and the A4 rockets toward redline with no sign of power running out until the car's rev limiter kicks in somewhere north of 6,000 rpm.

Audi's Quattro all-wheel drive also impresses, sending 60 percent of power to the rear wheels under normal conditions. It can route as much as 85 percent to the rear for some tail-drifting action, and the turbo A4 displays better dynamics and less nose-heaviness than the V-6 A4 that was offered at the outset of this generation. The new electric power steering for 2013, which shaves scant weight over the nose versus the prior hydraulic setup, also can't hurt. The A4 still lacks the outright driftability of a pure rear-drive sport sedan like the Infiniti G or BMW 3 Series, but it comes close enough for more casual enthusiasts.

The electric steering gets my thumbs-up. It still provides plenty of power assist at low speeds — long an Audi characteristic — where performance enthusiasts will probably find it too light. But the wheel firms up progressively as speed increases and responds with engaging feedback on curvy roads. A Driver Assist Package can adjust drivetrain and steering response — including the steering ratio, not just power assist — to comfort or performance settings. Audi got the steering right enough, though; the package may not be necessary.

Our test car had optional 18-inch wheels and lower-profile tires, as well as a sport-tuned suspension. The sport suspension had a firm ride, with noticeable disruption over angled slabs of pavement and the like, but it soaked up expansion joints and small potholes well. This version is sort of a midlevel performer, falling between the suspension extremes: the base A4's standard suspension with cushier 17-inch tires and the S Line Plus Package with 19-inch tires and the sport suspension.

EPA-estimated gas mileage with the manual is a respectable 22/32 mpg city/highway, but like some competitors, Audi requires premium gas. An eight-speed automatic is available on all-wheel-drive models, but it loses 2 mpg (20/30 mpg); front-wheel-drive cars have a continuously variable automatic transmission that gets 24/31 mpg.

Consistent Materials

Audi hasn't blazed new trails for interior design in recent years, but the consistency of its quality is still an industry benchmark. From the door panels to the center console, cabin materials have an attractive, low-gloss finish. My longstanding complaints are nitpicks — Audi could throw more padding atop the doors or engineer heftier window switches. Overall, I'm still a fan.

Space is not an A4 strength. The backseat is tight, with a large floor hump stealing footwell space. Trunk volume, at just 12.4 cubic feet, matches the Mercedes-Benz C-Class but trails the G (13.5 cubic feet) and 3 Series sedans (13.0).

Features, Pricing & Safety

For a starting price under $33,500, the A4 comes well-equipped, with standard features like genuine leather upholstery — not leatherette (vinyl) like many competitors throw in their base models — plus dual power seats, a moonroof and single-zone automatic climate control. It's on the audio front that the other shoe drops: The standard stereo includes just a CD player and auxiliary jack. USB/iPod connectivity plus Bluetooth phone and audio streaming — features many non-luxury cars include standard — remain optional. Other options include dual-zone automatic climate control, anavigation system, heated seats and a marvelous Bang & Olufsen stereo. Like most German sport sedans, the sky's the limit with pricing; check all the factory options and the A4 can climb past $50,000.

Reliability for the A4 has been good, but that isn't much of a differentiator. The 3 Series, C-Class, G37 and Lexus IS sedans are all fairly reliable, too. The A4 received Good scores in the Insurance Institute for Highway Safety's side-, rear-, roof-crush and traditional front crash tests, but it performed poorly — as did most of its peers — in IIHS' new small-overlap frontal tests, which aim to replicate a frontal collision where the impact includes just 25 percent of the car (see the results here). The C-Class, IS, 3 Series and Acura TSX received Marginal or Poor scores, too; only the Infiniti G, Volvo S60 and Acura TL received Acceptable or Good scores.

Standard features include six airbags plus the required antilock brakes and electronic stability system. Click here for a full list, or here to see our evaluation of child-seat provisions.

A4 in the Market

Even including sales of the related, two-door A5 and S5 — that's how luxury rivals group their coupe, convertible and wagon versions — total sales for the A4-derived family rank near the Infiniti G but fall a long distance behind Audi's German rivals. This car doesn't deserve to be so far behind.

Vehicle Overview

The five-seat A4 receives prominent styling updates for 2013, with the majority focused on the car's front end. It's offered only as a sedan, as the former Avant wagon has been dropped in favor of a new Allroad wagon, which is based on the A4 and covered separately in the Cars.com Research section. Audi also offers a performance version of the sedan dubbed S4, also covered separately. The A4 faces competition from the BMW 3 Series, Cadillac ATS, Infiniti G37 and Mercedes-Benz C-Class.

New for 2013

The A4 gets a redesigned front bumper along with a new grille, hood, headlamps and LED daytime running lights. There's also a restyled rear bumper. On the inside, the Multi Media Interface controls have been restyled and there are new chrome accents. The newly available Audi Connect telematics system uses 3G cell phone technology to enable Google Maps satellite-image overlays, real-time gas prices, weather information, news and Wi-Fi service for up to eight devices.

Exterior

The A4's styling bears a family resemblance to the larger A6. The sedan has a small spoiler integrated into the trunk lid. Exterior features include:

• Standard glass sunroof
• Standard 17-inch alloy wheels; 18- and 19-inch wheels available
• LED daytime running lights
• Available swiveling headlights
• Available xenon high-intensity-discharge headlights

Interior

Like other Audi models, the A4 has adopted the German automaker's Multi Media Interface, a system similar to BMW's iDrive and Mercedes-Benz's Comand systems. It controls functions such as the navigation system, stereo and vehicle settings. In the A4 and other Audis, MMI uses a knob controller and buttons on the center console for navigating menus and making selections from a dashboard screen. The available navigation system includes HD radio. Interior features include:

• Standard automatic air conditioning
• Standard leather upholstery
• Available upgraded stereo
• Available keyless entry and start
• Available Bluetooth and iPod connectivity

Under the Hood

All models have a turbocharged 2.0-liter gas four-cylinder engine. The base sedan comes with front-wheel drive and Audi's continuously variable automatic transmission. Quattro all-wheel drive is available and comes with a choice of a six-speed manual or eight-speed automatic transmission.

In this application, Audi's Quattro all-wheel-drive system has a torque split of 40/60 front to rear. This rear-biased design gives the A4 dynamics that are closer to a rear-wheel-drive car in addition to enhanced traction on both dry and slippery surfaces. Mechanical features include:

• 211-horsepower, turbo four-cylinder engine with 258 pounds-feet of torque
• Uses premium gas

Safety

Available safety features include Audi Side Assist, which informs the driver when another vehicle is next to the A4, and a backup camera. Rear side-impact airbags also are available. Standard safety features include:

• Four-wheel-disc antilock brakes with brake assist
• Front-seat side-impact airbags
• Front and rear side curtain airbags
• Electronic stability system
• Traction control
