The SQ5 is the performance-oriented version of Audi's Q5 SUV; both models were redesigned for 2018 with additional room and updated powertrains. The Q5 competes against the likes of the BMW X3, Porsche Macan and Mercedes-Benz GLC (compare them). The SQ5's main competitors are the Mercedes-AMG GLC43 and Porsche Macan GTS (compare them).

Mild Hides Wild

The SQ5's rounded curves and stately face are polished but hardly exciting; the thrill comes from under the hood. The car vaults off the line and stays strong after just a trace of turbo lag. The turbocharged 3.0-liter V-6 is good for 354 horsepower and 369 pounds-feet of torque — a bit more torque than the previous SQ5's supercharged V-6. Regular Q5 models use a 2.0-liter four-cylinder that's good for 252 hp; the Q5's four-cylinder pairs with a seven-speed dual-clutch automatic transmission while the SQ5 gets an eight-speed automatic. The Quattro all-wheel-drive system is standard.

The SQ5 powertrain's thrust is lively, but its sound is exhilarating. It thunders to life like the opening bars of the Imperial March — both ominous and thrilling — and Dynamic mode adds even more snarky, burly bark. Four driver-selectable modes alter the SUV's driving characteristics: Comfort, Auto, Dynamic and Individual. The modes change the accelerator response, transmission shift points, ride height, suspension firmness and steering effort to customize the SQ5's driving dynamics along the spectrum of sport and comfort. Auto is the default setting, and Individual can be programmed by the driver.

Overall, ride quality is firm but not punishing. The optional air suspension adjusts vehicle height as well as the firmness of the shock absorbers. The SQ5 comes alive in Dynamic mode with firm, connected steering and athletic handling. The accelerator's hair trigger delivered more responsiveness for quicker pep off the line, and the ride felt much firmer — even choppy at times. Comfort mode takes the edge off; there's a decent amount of cushioning, but the steering lightens up and handling loses some of its crispness.

Performance-oriented competitors match the SQ5's powertrain in potency — the Macan GTS makes 360 hp from its twin-turbocharged V-6, and the AMG GLC43's twin-turbo makes 362 hp — but fail to meet it in fuel economy. The SQ5 is EPA-rated at 19/24/21 mpg city/highway/combined, above the Macan GTS (17/23/19) and AMG GLC43 (18/24/20). All of these vehicles require premium gasoline.

Control Confusion 

Writing occupies a nice, cushy couch within my brain's comfort zone, while math transforms it into a waterboarding table. Coincidentally, that's also what's happened when I've tried in the past to use Audi's MMI multimedia system — it was more painful than high school calculus. The SQ5 uses the most recent version of the system and, though it's more straightforward than previous generations, it's still a long way from simple. Its learning curve is steep, and for me it required studying the owner's manual and watching a YouTube tutorial to figure out. Even after that, some of the system's more nuanced layers — swipe left for this, tap here for that — still eluded me and will likely take owners a lot of practice to master.

In the plus column, the tabletlike screen sits high on the dash for good visibility and has crisp, modern graphics — I especially appreciated the navigation's realistic Google Earth satellite view. However, it's not a touchscreen, so the driver's focus must shift down to a console-area knob and trackpad to control different parts of the system, from audio to navigation. (Thankfully, the climate buttons are separate and straightforward.) Using the knob for things like inputting an address into the navigation system is obnoxious and time-consuming. It also makes Apple Car Play and Android Auto operation clunkier.

The system earns points for its volume knob, but it's too far away from the driver and requires an awkward stretch. And the oddness continues: To use the knob as a tuner, you have to bump it like a joystick rather than twisting it. More oddness: The system's trackpad takes up a lot of real estate on the center console for not a lot of functionality. It houses the audio preset numbers, but its main role is to function as a writing pad — you "write" a letter with your finger to call up a destination in the nav system. Overall it feels gimmicky and is more time-consuming than using a touchscreen system; also, lefties will have even more trouble with the right-hand placement of the pad.

On the whole, MMI is better than before but has a long way to go in terms of functionality when compared with the industry's best systems, like touchscreen executions from Chrysler and Volvo.

Overstated Luxury 

A couple of things stood out about our SQ5's cabin — for better and for worse. First, we must address the lipstick-bedecked elephant in the room: the Magma Red interior. The lavish, quilted-leather seats and tasteful Carbon Atlas inlays convey elegance, but it's smothered by a big bucket of bright Magma Red. Like a well-placed lipstick, that kind of red should be a tasteful pop that adds some jazz to an otherwise ho-hum look. In the SQ5, it's everywhere, taking the cabin's finishes from understated to garish. Thankfully, other color palettes are available — like black.     

In other ways, the SQ5's interior is the picture of luxury. Cabin craftsmanship and materials quality are top-notch, like the plush padding and detailed stitching on the doors and console.

The bolstered rear seats are comfortable, and they slide and recline for added flexibility. By the numbers, the SQ5's backseat offers slightly less headroom than the GLC but slightly more legroom. (Porsche has not published backseat specs for the Macan.) Two adults will be comfortable in back, and I managed to squeeze my three kids and their car seats back there without much drama. My toddler twins' forward-facing convertible car seats went in without a problem thanks to the SQ5's exposed lower Latch anchors, and I fit my second-grader's compact, inflatable booster in the middle. A traditional booster would not fit. I had a tough time installing a rear-facing infant seat during our Car Seat Check due to inadequate legroom. 

Behind the backseat, there's 26.8 cubic feet of cargo space, more than the GLC43 (19.4 cubic feet) and Macan (17.7 cubic feet). Fold the seats to create 60.4 cubic feet of space — again, more than the others. I fit a full grocery run in the cargo area (with the seats in place) and found the adjustable suspension's lower loading height useful when loading and unloading bags. The cargo wall's small netted bins were also handy for corralling fragile groceries (like bottles of wine).

Safety

The 2018 Audi SQ5 had not yet been tested by the Insurance Institute for Highway Safety or the National Highway Traffic Safety Administration as of publication.

A backup camera is standard; a 360-degree camera system is optional. Standard Audi Pre-Sense Basic, a crash-preparation system, closes the windows and moonroof and tightens safety belts before impact. A forward collision warning with automatic emergency braking system is also standard, as are blind spot warning and rear cross-traffic alert systems. Lane departure warning is part of the optional Driver Assistance package.

Sticker Shock

The 2018 SQ5 starts at $55,275 including destination, about $1,000 more than the 2017 version and $12,800 more than the regular Q5. The version I tested clocked in at $68,750 after extras like those quilted Nappa leather seats, an adaptive suspension, 21-inch wheels, navigation and a premium sound system, among other features. That sounds steep, but competitors start even higher: The AMG GLC43 starts at $57,245 and the Macan GTS at $69,950 (all prices include destination charges).

The SQ5 appeals in its balance of a classy, elegant vehicle with a fun factor in a way that few in the class manage as astutely. Its engaging road manners add an air of excitement to the everyday personality of the Q5, but Audi is overreaching with the SQ5's designer-label price premium.
