Mercedes-Benz CLA200 vs Audi S3

What's the difference?

The Mercedes-Benz CLA 200 is sleek, well-equipped, and beautifully engineered. That said, it’s pricey. You can get a car that’s 80 percent as good for 50 per cent of the price. But getting that extra 20 percent in terms of refinement, dynamic ability and design sophistication is what you’re paying for. If you’ve got the extra dough, top dollar buys you a spot on the top shelf.

The updated Audi S3 Sportback is a fun-sized dynamo with impressive outputs and athletic road manners. It’s missing a few premium features, but its compact size paired with a gutsy engine makes it a compelling option for drivers who don’t want to compromise on performance (just space).

While the way a car looks is a subjective call, and as always, your thoughts are welcome in the comments below, I’m putting it out there… this is a beautiful machine. And Gordon Wagener’s not pulling any punches, either. He thinks it has the potential to become, “a modern design icon.”

The long bonnet, cab-rear, wide-track proportions sit within a slightly larger footprint. The new CLA is marginally longer, wider, lower overall, and has a lengthier wheelbase than the model it replaces. And the car’s intricate mix of gently curved surfaces and hard lines is expertly managed, with a standard AMG body kit, complete with 18-inch rims, adding just a hint of macho intent.

The angle of the shoulder runs from this character line, virtually unchanged up to the roof, and the inward slope of the side glass (car designers call it tumblehome) is quite pronounced. And the sweeping curve at the top of the front guards is defined by hard strakes on the outer edges of the bonnet.

The rear view is arguably the CLA’s most appealing angle with the intersection of the sloping turret, boot, and rear guards neatly resolved.

It’s super slick aerodynamically, as well, boasting a Cd of 0.23, running a close second to it’s A-Class sedan sibling (0.22) which Merc claims as the world’s most aero-efficient series production four-door.

But what about the inside? Well, the biggest visual feature is the customisable MBUX media and data interface, expressed dramatically through a pair of 10.25-inch widescreens.

The info available and number of configurations offered is mind-blowing. It’s very 2019 and spot-on target for the digital generation.

Piano black surfaces around the dash and console lift the tone (but pick up the fingerprints) while the signature turbine-style vents add another flash of visual interest without compromising function.

Other highlights include front seats with racy one-piece backs (reflected on the top of the outer rear seats, as well), frameless doors enhancing the coupe feel, and neatly detailed stitching around the dash and doors.

The S3 Sportback may be a small car, but its S design features, like the stylised blackout grille, matrix LED headlights, and 19-inch alloys with red brake calipers, give it a distinctly athletic and fun-loving vibe. It’s compact, but definitely not diminutive and carries serious road presence. It’s hot hatch meets fun-size.

Inside, the S3 looks fabulous. Integrated ambient lighting, a sharp dashboard treatment and a driver-focused cockpit all lend it a premium feel.

The front seats look properly sporty with their integrated headrests, and the quilted Nappa leather upholstery feels great, especially with the eye-catching red contrast stitching.

As for technology, it’s as high-end as you’d expect with a 10.1-inch touchscreen multimedia display and 12.3-inch digital instrument cluster taking centre stage.

The only drawback? No sunroof. Combined with the black headliner and compact cabin, it can feel a little gloomy at times. Still, it’s a cabin you’ll enjoy spending time in.

Despite a two mm drop in overall height, the CLA’s front headroom has been extended by 17mm, and there’s lots of room up front, with storage running to two cupholders in the centre console, a lidded bin/armrest between the seats (including twin USB ports), an overhead sunglass holder, decent door pockets with room for bottles and a medium-size glove box.

There’s also a mat for wireless device charging at the front of the centre console, complete with another USB input (just in case).

But what does that sexy, sloping roofline do for space in the rear?

Sitting behind the driver's seat set to my (183cm) position, there’s adequate legroom, but despite Merc claiming an extra 3.0mm of headroom, my noggin made firm contact with the headliner.

It’s worth remembering this is a coupe-style four-door, with the packaging compromises a swoopy roof brings. You could call it a ‘2+3’, with a couple of doors added to make access to the back seats easier.

A centre fold-down armrest incorporates two cupholders, again there are generous pockets in the doors with room for bottles, map pockets on the front seatbacks, and adjustable ventilation outlets set into the back of the front centre console are a welcome inclusion.

There are three belted positions across the rear, but the adults using them for anything other than short journeys will have to be good friends and flexible. Kids will be fine.

Boot volume is a healthy 460 litres (VDA), which is down 10 litres on the first-gen car, but the aperture has been widened by no less than 262mm, and a 40/20/40 split-folding rear seat opens up extra space. There are tie-down hooks, a 12-volt outlet and elasticised storage pockets either side of the load space to further enhance useability, plus a cargo net is included.

No news on towing capacity at this stage, and don’t bother looking for a spare, the tyres are run flats.

Like most hatches, the front row enjoys the most space. While it’s cosy, it never feels cramped. The seats are firm yet comfortable, thanks to their adjustability and expandable under-thigh supports. Access is fairly easy with wide door apertures, though the low seating position might earn a few grunts, especially from taller folks.

Storage up front is well sorted, with a glove box, a small centre console, a dedicated phone cradle and a couple of cup and bottle holders. It’s about what you'd expect for a car this size, but it's enough to keep things tidy.

There are plenty of charging options, with two USB-C ports in each row and a wireless charging pad up front.

The multimedia system is intuitive and easy to use. The touchscreen is responsive, and wireless Apple CarPlay connected without fuss and stayed connected all week. Wireless Android Auto is available, too.

Built-in sat nav is clear, and I love the way directions pull through to the digital instrument panel. The Sonos sound system? Pretty darn good. My son and I had more than one mini-concert on the school run.

As for the rear row, it definitely reminds you this is a small car. At 168cm, I found it on the cramped side of cosy and my husband just laughed when I asked him to try it! The wheel arch also cuts into the door aperture, making access a little awkward. Best to think of it as occasional adult seating. But given the size, that’s no surprise.

Amenities in the back are decent with a couple of map pockets, cup and bottle holders, as well as a fold-down armrest, those USB ports and rear temperature control (but curiously, no fan control). The seats are comfortable enough, but space is limited. Realistically, it’s best suited for two passengers, not three.

Boot space is quite practical. The wide opening and manageable load lip height make it easy to slide items in and out. It offers 325L of space, less than its key rivals, but expands to 1145L with the rear seats folded flat. The handy 40/20/40 split also adds versatility. Under the boot floor, you’ll find a tyre repair kit.

The A3 Sportback comes in three trim levels, with the S3 technically sitting in the middle, just below the performance-focused RS 3. It's priced from $78,800, before on-road costs, and it shares the same platform and underpinnings as the Volkswagen Golf R. Surprisingly, our test vehicle isn’t significantly more expensive than its Golf R rival which comes in at $70,990 MSRP.

That makes it a more affordable option when compared to premium rivals like the BMW M135 xDrive which starts at $83,600 MSRP and the Mercedes-AMG A35 which comes in at $89,700 MSRP.

The update sees engine outputs improve with it gaining 17kW and 20Nm of torque, resulting in a total of 245kW and 420Nm.

Feature highlights include 19-inch alloy wheels, red brake calipers, electrically-adjustable and heated front seats (with expandable under-thigh support), rear privacy glass, quilted Nappa leather upholstery and 'S Sport' suspension with damper control which lowers the ride height lowered by 15mm.

The updated technology is well-rounded and now comes with wireless Apple CarPlay and Android Auto. There's also three-zone climate control, a 10.1-inch touchscreen multimedia display, a 12.3-inch digital instrument cluster, digital radio, four USB-C ports, a wireless charging pad, built-in satellite navigation and a 15-speaker Sonos 3D sound system.

Still, despite its premium hot hatch status, this grade skips a few luxury touches. Ventilated front seats, a heated steering wheel, heated rear outboard seats and a sunroof are all missing. The BMW M135 xDrive, notably, includes all of these as standard.

Even the powered tailgate with kick-functionality is an optional extra here, adding $660 to the price. At this level that should be standard.

The CLA 200 is powered by Merc’s 1.3-litre (M 282), direct-injection four-cylinder turbo-petrol engine driving the front wheels through a seven-speed dual-clutch auto transmission (with paddle shifters on the wheel).

It’s the product of a joint development with Renault, and outputs are 120kW at 5500rpm and 250Nm at 1620rpm, which is pretty impressive for such a small capacity unit.

The single turbo features an electronically controlled wastegate and flexible charge pressure control to optimise boost across the entire rev range (rev ceiling is 6300rpm), with an equal focus on power, step-off throttle response and fuel efficiency.

The S3 Sportback wears the quattro badge proudly, meaning it’s all-wheel drive and it pairs a tweaked seven-speed automatic transmission with a 2.0-litre turbocharged, four-cylinder petrol engine.

This update brings a bump in performance over the previous model, including the addition of a rear torque splitter. Power is now up to a gutsy 245kW and 420Nm of torque, launching the S3 from 0 - 100km/h in just 4.7 seconds. That’s proper hot hatch territory.

Claimed fuel economy for the combined (ADR 81/02 - urban, extra-urban) cycle is 5.7L/100km, the CLA emitting 130g/km of CO2 in the process.

At just over 1.4 tonnes it’s fairly hefty for its size, but at partial load between 1250-3800rpm two of the engine’s four cylinders shut down to improve economy. ‘ECO’ mode dampens performance in the name of improved economy, plus stop-start is standard.

And over roughly 200km of freeway, city and suburban running we saw an average of 7.5L/100km courtesy of the on-board read-out.

Minimum fuel requirement is 95 RON premium unleaded, and you’ll need 43 litres of it to fill the tank, which at our real-world average delivers a range of approximately 575km.

The S3 Sportback has an official combined fuel consumption figure of 7.9L/100km and a 55-litre fuel tank, giving it a theoretical driving range of up to 696km.

Its key rivals hover around similar numbers, so it's right on the mark for the segment. After a mix of long-distance drives and my usual urban errands, my real-world figure came in at 8.0L/100km - very close to the claim, which I’m pretty happy with.

So, despite the engine’s small capacity the addition of a turbo means peak torque (250Nm) arrives at just 1620rpm. Power delivery is linear and mid-range acceleration is healthy. Claimed 0-100km/h acceleration is 8.2sec, which is neither sluggish nor particularly fast, but performance is more than adequate around town and on the highway.

The seven-speed dual-clutch auto shifts smoothly, but not particularly rapidly, although a switch to manual mode and use of the wheel-mounted paddles means you can be more selective about which ratio you’re in and for how long.

Standard suspension set-up is strut front, multi-link rear, with many of the components made from aluminium to reduce unsprung weight, and the CLA feels nimble through twisting backroad bends.

Our test car was optioned with the AMG Exclusive Package, which includes adaptive dampers. And no surprise ‘Sport’ mode is severe, and the fillings in your teeth (unless you’re one of those strange people that don’t have any) will be in danger of rattling loose over anything other than a billiard table smooth surface.

By contrast, ‘Comfort’ lives up to its name with a supremely compliant ride without any sacrifice in terms of balance and (taut) body control. The standard 18-inch rims, shod with 225/45 rubber, don’t put a disenable dent in proceedings, either.

The electro-mechanical steering points accurately and delivers a good connection with what’s happening at the front wheels. Assistance is subtle.

Brakes are vented discs up front, with solid rotors at the rear. Purely in the interests of a full and well-rounded review we enthusiastically pushed through some lengthy B-road sections, and the pedal remained firm and consistent.

In short the CLA is a refined city coupe that doubles as a comfortable touring car.

The S3 Sportback sounds as mean as it looks, and it delivers on that promise with effortless grunt. Acceleration is immediate, with plenty of power on tap when you need it. It’s just fun all around.

The lowered sports suspension and wide tyres do bring some extra noise into the cabin, even at lower speeds. You might find yourself repeating things to rear passengers now and then, but it never feels overwhelming.

Steering and suspension are on the firmer side, so yes, you’ll feel the bumps but the payoff is sharp, responsive handling. Quick lane changes and winding coastal roads are where this car shines.

Visibility is about what you’d expect from a low-slung hot hatch. The pillars don’t obstruct the view, but sitting beside a towering SUV at the lights can make you feel a bit... compact.

Cornering is a strong suit, thanks to the car’s wide stance and AWD system. It feels confidently planted in most conditions. That said, I noticed the occasional wobble through the rear frame on rough sections in heavy rain.

Its compact size makes parking a breeze, especially with the help of multiple sensors. The reversing camera is crisp, but at this price point, the lack of a 360-degree camera view feels like a missed opportunity.

The S3 isn’t covered by its 2WD sibling's maximum five-star ANCAP safety rating but it is well-equipped with safety features all the same.

Safety equipment includes blind-spot monitoring, side exit assist, rear cross-traffic alert, lane departure alert, lane keeping aid, park assist, reversing camera, front/rear parking sensors, forward collision warning, autonomous emergency braking and adaptive cruise control with stop and go function. 

It also has six airbags but misses out on a front centre airbag. None of the driver assist systems are intrusive to daily driving, which I always like.

The rear row has ISOFIX child seat mounts and three top-tether anchor points but only two child seats will fit.

The Mercedes-Benz range is covered by a three year/unlimited km warranty, which, like Audi and BMW continues to lag behind the mainstream market where the majority of players are now at five years/unlimited km, with some at seven years.

On the upside, Mercedes-Benz ‘Road Care’ roadside assistance is included in the deal for three years.

Service is scheduled for 12 months/25,000km (whichever comes first) with pricing available on an 'Up-front' or 'Pay-as-you-go' basis.

For the CLA, pre-payment delivers a $500 saving, with the first three services set at a total of $2050, compared to $2550 PAYG. Fourth and fifth services are also available for pre-purchase.

Audi backs the S3 Sportback with a five-year/unlimited kilometre warranty, which is on par with its European rivals. A five-year pre-paid servicing plan is available for $2890 which is cheaper than pay-as-you-go and reasonable for the class.

For those looking to go the extra mile, the 'Audi Advantage' package lets you extend the warranty and capped-price servicing by an additional two years, which represents solid value overall.

Servicing intervals are every 12 months or 15,000km, whichever comes first.
