Mercedes-Benz CLA200 vs BYD Sealion 6

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.

So, should Toyota, Tesla, Hyundai and others be worried about the arrival of the Sealion 6 and BYD’s new DMi powertrains? Yes, but not because it represents any major breakthrough in technology or dynamic prowess. 

Instead, the strength of the Sealion 6 is how average it is. It may not be the obvious class-leader in any particular area, but it does a good job in almost every measurable aspect and doesn’t possess any major flaws.

Yes, there are still questions about the long-term dependability of BYDs but that’s a risk any new owner will need to accept. But the very sharp pricing should tempt plenty of buyers to take that chance and continue BYD’s steady upwards trajectory in the Australian market.

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.

This is one area where BYD has a mixed record. Not to be unkind or create an international incident, but the Chinese car industry has a history of not being totally original with all of its automotive designs.

However, things are improving and the Sealion 6 is a good example of the Chinese industry learning to develop its own style. While there are some subtle hints from European models, overall it’s a smart-looking mid-size SUV with some character to it - rather than being a bland imitation of something else.

One area where the Sealion is a cut above its competition is its size, being longer than and wider than the RAV4, Mitsubishi Outlander and Nissan X-Trail.

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.

That external size translates to a roomy cabin, which also has some flair to the design but thankfully a bit more restrained than the smaller Atto 3 - which is a bit over-the-top in this reviewer’s opinion. 

The element that sticks out immediately is the large central touchscreen which, like other models in the range, can rotate either vertical or horizontal, depending on your preference.

I don’t understand the point of this, because when rotated vertically it impacts your forward vision and can interfere with the air conditioning vents; and I can’t even see it with my polarised sunglasses.

It simply makes more sense horizontally, but I guess all carmakers are looking for catchy gimmicks these days. But while it may seem like a cool party trick it remains somewhat confusing to me, like one more thing to go wrong. But maybe I’m just getting old and grumpy.

What I do like and think is a great idea is double smartphone charging pads in the centre console. And overall the design of the cabin feels well thought out and has plenty of useful storage areas.

The seats are fine, a little flat and the fixed headrests are irritating, but overall they’re soft and supportive enough.

The key in the second row seating is the amount of space, with the extra length of the Sealion 6 compared to its rivals showing up with more knee room in the back for families with growing teenagers or those who need to carry their adult friends.

There’s also a pair of USB ports in the back too, so everyone can keep their electronics charged.

The boot is a good size, measuring 425 litres on paper, and has a nice long and wide floor. But some of that space is thanks to the lack of a spare - so that counts against it in my book.

Price is key to BYD’s success in Australia. Quite simply, the Chinese brand has undercut its rivals and consumers have responded to that, unsurprisingly in these tough economic times. The Sealion 6 follows the same path blazed by the Atto 3, Dolphin and Seal, offering plenty of vehicle for your money.

BYD Australia has kept it really simple, offering just two models - Dynamic and Premium - with very similar specification and separated primarily by powertrains.

The Dynamic is a less powerful, two-wheel drive option, while the Premium gets more grunt and all-wheel drive; but we’ll detail that later.

Both the Dynamic and Premium come with 19-inch alloy wheels, power-operated tailgate, a panoramic sunroof, powered front seats that are heated and cooled, a 15.6-inch touchscreen, Infinity premium audio, two wireless phone chargers and wireless Apple CarPlay and Android Auto.

The only non-powertrain difference between Dynamic and Premium is a head-up display on the latter model.

One noticeable absence from the Sealion though is a spare tyre. There’s not even a space-saver, just a tyre repair kit, which is disappointing and out of touch with the unique demands of the Australian market.

The Dynamic is priced from $48,990 (all prices exclude on-road costs), while the Premium starts at $51,990.

To put that into context with its competition, the Toyota RAV4 Hybrid range begins at $42,250 for the GX and stretches to $51,410 for the range-topping $51,410.

While, if you’re looking at an electric alternative, the Tesla Model Y currently starts at $55,900. The most direct rival, however, is the Mitsubishi Outlander PHEV which is only available with all-wheel drive and stretches from $57,290 to $73,790 across five variants.

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.

While BYD has made its name in Australia as an all-electric brand it has always referred to itself as a 'new energy' company, and the Sealion 6 (and upcoming Shark ute) are why.

That’s because these feature BYD’s new 'Dual-Mode Intelligence' (DMi) powetrain - a hybrid system to you and me.

As mentioned above, the biggest difference between the Dynamic and Premium models is the powertrain, with two reasonably different systems.

The Dynamic is powered by a 78kW/135Nm 1.5-litre four-cylinder petrol engine, paired with a 145kW/300Nm electric motor - making for a combined system output of 160kW/300Nm. Notably, this powertrain only drives the front wheels.

In contrast, the Premium has an all-wheel drive set-up, combining a turbocharged version of the petrol engine (good for 96kW/220Nm) with a pair of electric motors, one on the front axle and one on the rear to produce a combined output of 238kW and 550Nm.

Both models get the same 18.3kWh ‘Blade’ battery, which is BYD’s proprietary technology underpinning all of its models and is attracting attention from other brands.

For reference, the Outlander PHEV has a 20kWh battery, Nissan’s X-Trail e-Power has a 2.1kWh battery, while the more conventional RAV4 Hybrid has just a 6.5Ah battery.

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.

There are multiple modes to drive it in, including electric only, with the Dynamic able to go up to 92km on a single charge, while the Premium manages a claimed 81km.

However, it's important to note these are the NEDC standards and not the more real-world like WLTP,  so you may not achieve those in practice.

The claimed fuel consumption is an impressive 1.1L/100km for the Dynamic and 1.4L/100km for the Premium although again achieving those in the real world will take some effort.

With a 60-litre fuel tank BYD claims the Dynamic has a driving range of just over 1000km, while the Premium can manage around 960km.

It's also worth noting the Sealion 6 comes equipped with vehicle-to-load charging which means you can draw power from the batteries to run small electronic devices if you need to.

It’s a bonus feature that may or may not be of use, but is one of those things that may come in handy one day to get you through a camping trip or a BBQ at the park.

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.

We drove the Sealion 6 Dynamic and despite having the less powerful powertrain it feels good on the road. The DMi system offers good performance, with quiet acceleration off the mark and a good integration between the petrol engine and electric motors. We haven’t driven the Premium yet, so we can’t make any comment on how different it feels.

It’s hard to make a definitive call on the Sealion PHEV powertrain because, like every plug-in hybrid, its greatest strength relies on how the owner operates it.

If you don’t charge the battery every day or so, you’ll just end up lugging around a battery and electric motor for little benefit. However, if you do keep the battery topped up, you can do most of your urban commuting without needing to turn the petrol engine on, which should result in some very low fuel consumption figures.

The company clearly knows this, which is why BYD Australia is offering a complimentary home charger to the first 3000 customers who order a Sealion 6.

Not only will that encourage sales but it will also help owners become evangelists for PHEVs in the future, because they’ll have the best possible experience.

So, a large part of its strength or weakness rests on the owner’s behaviour and that’s something we can’t assess.

As for the rest of the driving experience, the ride comfort is fine. It can’t match the class-leaders for compliance or dynamics, but the Sealion feels pleasant to drive around the urban environment and on the freeway at speed.

Biggest criticism is the steering is very, very light. While that makes parking easier, it feels so light you get very little feedback from the front wheels so it can feel vague at times.

Overall the driving experience is best described as fine. It doesn’t have any major vices but neither does it set any new benchmarks. 

Both Sealion 6 variants come equipped with autonomous emergency braking, front and rear cross-traffic alert/braking, 'Forward Collision Warning', 'Rear Collision Warning', lane departure warning/prevention, blind-spot detection, traffic-sign recognition, door-opening warning, trailer stability control, auto high beam, a 360-degree monitor, adaptive cruise control as well as front and rear parking sensors. Plus, it can even detect if you’ve left a child or pet inside the car.

ANCAP had not crash-tested the Sealion 6 at the time of publication, but with its comprehensive list of safety items it should tick most of the boxes when it comes to protecting its occupants and pedestrians.

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.

BYD is a small company but has partnered with mycar service centres to make maintaining your Sealion 6 easier. The Sealion is covered by BYD's six-year/150,000km warranty as well as its 10-year capped price servicing plan.

Service intervals are every 12 months/20,000km and prices range from $265 up to $1184 for the major eight year/160,000km tune up. Over the first five years, in keeping with most of its rivals, you’ll be paying $1648.

As I’ve written in previous BYD reviews, the biggest question mark hanging over the brand is arguably its long-term prospects. Quite simply, the brand is still too new to know how well it will perform on the used car market.

We also can’t tell you how it will hold up from a reliability point-of-view. We’re not suggesting there’s any doubt over its quality, but each car brand must prove itself reliable and dependable over time, and BYD hasn’t had that time yet.
