Mercedes-Benz SL-Class vs Chery Tiggo 8

What's the difference?

The SL's overall score is somewhat skewed by everyday concerns, and rules are rules - an average punter will find the price of this car somewhat confusing and the devil-may-care attitude to fuel consumption bewildering.

If neither of these things are a problem, then the SL63 makes plenty of - well, not sense, because it's not a particularly clever or considered car - but it fills a niche that not so long ago we all thought would go the way of the dodo.

The fact it sells so few examples is betrayed by some of the cabin amenities and the fact that Mercedes hasn't put much effort into reducing the car's weight to improve its consumption or sharpen up the handling.

The fact it still exists at all is pretty damn cool, though, and for certain people an SL63 purchase is the culmination of a lot of hard work.

If it is your dream car, the SL63 won't disappoint. Everyone who rode with me said it was mightily impressive, but you've got to really want it. When you're not far off buying a Ferrari California T or Aston Martin V12 Vantage S for the money, you'll need a real yearning for the three-pointed star to go this way. And if you do, good luck to you - you've probably worked quite hard to get here.

A bargain price, clever hybrid system, and a spacious interior with useful third row is a rare and potent combination which should continue to catapult Chery into a successful future.

Sure, the dull driving dynamics, sometimes befuddling software, and over reliance on touchscreens could and should be addressed, but at this price and with these ownership terms, the Tiggo 8 Super Hybrid is a tough proposition to argue with.

Note: CarsGuide attended this event as a guest of the manufacturer, with accommodation and meals provided.

The SL has always been completely unapologetic about its size and seems to be designed to accentuate rather than hide its length and width. The long bonnet screams power and prestige, and get out of my way, and is reminiscent of the little-loved McLaren SLR project of some years ago.

The size of the Mercedes logo on the huge front grille leaves you in little doubt about the brand of car that’s about to pass you at speed and some might say (okay, I would) that its large surface area is a little vulgar.

Like the SLR, the design doesn't seem to have a particularly cohesive strategy, with a number of Mercedes elements from around the traps that climb over each other. Roof up it looks awkward because of the gigantic posterior while with the roof down it looks overly long and, again, tail-heavy.

Folding hardtops are notoriously cumbersome and need a lot of room to hide them, but the silent operation is something to behold.

Elements that are worth deleting if possible are the dodgy 'Biturbo' badges. It's that kind of bling that gets people raising their little finger at you.

Unlike some of its rivals in this space, the Tiggo 8 has a fairly generic boxy SUV design. It’s not as interesting as many of its rivals, but it also strays away from being controversial.

The derivative grille design and light signatures make it blend into traffic nicely, making it an ideal SUV for someone who intentionally doesn’t want to stand out, at least not in quite the same way as something like the BYD Sealion 6.

There’s also nothing that looks proportionally off about it, and the strong lines and spoiler piece over the rear give it a (very) faint air of toughness.

Inside this plug-in hybrid version gets a significantly different interior compared to the combustion Tiggo 8 that launched in 2024. The design is much more contemporary, dominated by the huge central touchscreen which is much bigger than the one in both the Tiggo 7 and the combustion Tiggo 8, and there’s new switchgear for the indicator stalk and for the steering wheel buttons, too.

Unfortunately, this comes at the cost of the climate shortcut panel which remains in the Tiggo 7. Instead, you’re forced to navigate through new software which has a dedicated climate zone.

Still, it’s a glitzy looking interior with big screens and interesting material choices, particularly at this price. The Tiggo 8 even manages to avoid some of the blatant Mercedes-Benz worship as seen in the smaller Tiggo 7, and the synthetic seat trim is also distinct from the rest of the Chery range. In this plug-in Tiggo 8 it’s a kind of sturdy-feeling neoprene finish which looks a little bit like suede. It’s weird, but I don’t hate it.

“Practicality” is about as relevant to this car as a code of ethics is to a drug dealer or a contract killer, because the SL63 buyer is hardly worried about cupholders and boot space. For what it's worth, there are four cupholders in the two-seater cabin (which might explain why owners aren't worried about their liquid carrying prospects) and a minimum boot space of 364 litres and a maximum - with roof up - of 504, which is actually not bad.

Cleverly, there's a little robot-operated luggage cover inside the deep boot that stops your gear from being crushed when the roof goes down.

There's also space in the long doors where you might secrete a bottle of wine that would get a NSW Premier fired if he thanks you for it, and a bin in the console to hide your phone.

The Tiggo 8’s cabin is enormous and has had various upgrades since the combustion car launched that make it both easier and less easy to use.

For example, the centre console redesign is more contemporary, offering pride of place to the wireless phone charging bay, offering two larger bottle holders off to one side. Some key driver functions appear on the right-hand side, including a drive mode selector dial and a handful of shortcuts for the most basic climate functions, like an auto AC button and front and rear defoggers.

This means the shifter has moved to the column on the right-hand side, with a multifunction stalk for the indicators and wipers on the left instead.

The armrest console box is an overcomplicated split opening design, but offers plenty of room inside. There are two large bottle holders and pockets in each front door, too, and there’s a large pass-through area underneath the bridge-style console which will be great for a handbag or something.

The seating position is quite adjustable, but you sit unusually high in the car, which makes it feel as though you’re peering down on the instruments.

As already mentioned, the full array of climate functions can only be controlled through the touchscreen, with no physical buttons outside of the handful on the centre console. Would it be so hard just to have a temperature and fan speed dial you don’t have to take your eyes off the road?

The software itself is typical of many Chinese cars at the moment. It looks good, but isn’t as functional or easy to use as you’d like. Some core functions are still buried in confusingly labelled sub-menus, particularly things like active safety features. It’s not the worst I’ve used (the Leapmotor C10 springs to mind), but it should be better given the massive screen is such a focal point of the cabin.

At least the Tiggo 8 doesn’t feel cheap in other areas, with generous soft-touch materials throughout the cabin. It might be fake leather and suede, but it does a good enough job of making the cabin feel plush and comfortable for longer journeys.

The second row is impressive. I had leagues of room in all dimensions behind my front seat position at 182cm tall. The generous amount of soft trims continue and the seat bases are comfortable enough, too. Storage comes in the form of seat-back pockets and large bottle holders in each door.

Maybe the most impressive feature is the third row. While I felt squashed into the rear row of the Mitsubishi Outlander, the Tiggo 8 offers just enough space for an adult to travel in some form of comfort. Access isn’t the easiest, but there’s so much space in the second row the the seat can slide forward to allow sufficient room for my legs. My head touches the roof, however.

There’s not much in the way of amenities back there, with a bottle holder and storage tray for third-row occupants, as well as a 12-volt outlet in the boot.

The boot itself seems large enough, although at the time of writing there was no official boot figure. For context, the combustion version offers 479 litres with the third row down, or 117 litres with it up, and this plug-in doesn’t seem significantly different to my eye.

Unfortunately though, the placement of the battery and DC inverter under the boot floor leaves no room for a spare. There’s only an inflator kit.

The Tiggo 8 Super Hybrid is also super affordable. With a price of just $45,990 drive away, it’s a terrible day to be the product planner for Mitsubishi’s upcoming Outlander PHEV facelift which used to be one of the only options in the space.

In fact, it’s bad news for any mid-size SUV, whether they’re combustion powered, hybrid, or previously good value.

For context, the outgoing Outlander PHEV started from $57,290 before on-roads, and even MG’s five-seat-only plug-in hybrid HS costs from $52,990. You can have the BYD Sealion 6 for less, at just $42,990 for a base essential, but it is also just a five-seater.

If it’s just a plug-in hybrid you want and you don’t need seven seats, the smaller Tiggo 7 bests them all, starting from a new low of $39,990 drive-away.

Regardless, the low price and big hybrid battery (we’ll talk more about this later) don’t stop the Tiggo 8 from being packed with standard gear. 

Highlights on the entry-level Urban spec include 19-inch alloy wheels, LED headlights and DRLs, a 10.25-inch digital instrument cluster, a 15.6-inch multimedia touchscreen with wireless Apple CarPlay and Android Auto, a 50W wireless charger, synthetic leather seats, ambient interior lighting, six-way power adjust for the driver’s seat, a 360-degree parking camera, and even an acoustic windscreen.

Not only is this impressive equipment, but the Tiggo 8 is more than just a seven-seat version of the Tiggo 7, with a larger touchscreen and some standard kit like the 360-degree parking camera and wireless charger, which don’t come on the most basic version of its sibling.

The top-spec Ultimate, which costs $49,990 drive-away, adds heated and ventilated front seats, two additional speakers (bringing the total to 12), a head-up display, a panoramic opening sunroof, privacy glass, illuminated scuff plates, and a message function for the front passenger.

It’s hard to see how the Tiggo 8 isn’t good value full stop, and it's a plug-in hybrid!

The SL63 is powered by Mercedes’ increasingly famous V8, with two turbos along for the ride to add oomph and cut the car's famous consumption, at least slightly. The 5.5-litre unit produces a massive 430kW and a scarcely believable 900Nm of torque.

All of that heads rearward via a seven-speed dual-clutch transmission that helps sling the 4.6m, 1848kg machine to 100km/h in 4.1 seconds.

Chery’s Super Hybrid system is a little different from other plug-ins on the market. It pairs a 1.5-litre four-cylinder turbocharged engine (105kW/215Nm) with a ‘dedicated hybrid transmission’ (DHT). This is a transaxle which contains a large electric motor (150kW/310Nm) and uses a set of clutches and gears to blend the power sources.

The end result of this is a drivetrain that feels a bit like a CVT but isn’t the much derided rubber-band-on-a-cone set-up. To Chery’s credit, it almost feels like driving an electric vehicle, such is the relatively smooth power delivery and seamless blending of the power sources depending on speed.

Just don’t expect to tow much more than a tinny as capacity is limited to just 750kg.

Much as is the case with the price, there's no real way to soften the blow here - the SL63 drinks like a footballer on Mad Monday, except it does it every day. The official combined cycle figure of 10.2L/100km is quite easy to double, as we did, averaging 21L/100km in mostly flowing suburban traffic. In the car’s defence, the accelerator pedal spent a good deal of time near the firewall.

The SL does have stop-start to help reduce its considerable environmental impact.

The Tiggo 8 has a headline electric driving range of 95km, although this is rated to the more lenient NEDC cycle. Usually you can expect more like 75km in the real world, but these plug-ins tend to vary greatly from their official figures for better or worse, so stay tuned for a longer test to see what the real-world figure is.

Regardless, it draws this range from a 18.3kWh battery pack, that is capable of charging up on both DC and AC, which is rare for a plug-in. On the faster DC chargers, it is capable of topping up at a maximum rate of 40kW for a claimed 30 to 80 per cent charge in 20 minutes. Combined range, using a full tank of fuel and full charge can have the vehicle travel up to a claimed 1200km.

The overall fuel efficiency is 1.3L/100km, a somewhat useless figure. The actual figure will depend entirely on how you use the car. Have a short commute and charge at least at one end of it? It may as well be zero.

What’s particularly clever though is how Chery has put significant work into the software map of the hybrid transmission to keep it as efficient as possible, even when the battery is drained. 

The vehicles we tested on the launch were all hovering around the mid-5.0L/100km mark, even with the batteries long drained to their reserve level. The brand’s engineering people say the software map is specifically designed to achieve less than 6.0L/100km even when the battery is dead.

Again, not every plug-in hybrid can claim the same.

There are a number of impressive things about the way the SL drives. Firstly, astronauts will be familiar with the galactic thrust of the V8. It seems endless, seamless and ready to sling the big coupe into the outer atmosphere. Few engines of any kind can match the relentless go on offer in the SL and much of the credit should go to the seven-speed twin-clutch transmission.

When you jump on the brakes and shift down, the exhaust keeps the show going with angry crackles and pops.

Containing a torque figure like the twin-turbo V8's requires a lot of electro-trickery to stop you from being launched off the road. The great thing about all that stuff is that it works unobtrusively and smoothly.

Mashing the carpet in an SL without traction control would create much sound and smoke but little forward progress, such is the twist on tap. The SL has a range of modes from full-nanny (which is meant to keep you on the slippery Alpine road you've chosen to get you to some Swiss ski resort) while turning the dial all the way around to Race loosens the bonds.

It's in this mode you'll have the most fun and it does seem that the intermediate settings are a bit of a waste of time. Race mode does little to diminish the amazing ride quality provided by the active suspension setup, but relaxes the reins on the huge rear tyres. Exiting roundabouts is suddenly a huge laugh, with the tail cheerfully breaking traction and the two-mode exhaust thundering in a most pleasant way.

Better still is that when you jump on the brakes and shift down, the exhaust keeps the show going with angry crackles and pops, with more on the way when you lift off. There's little to match the aural pleasures of a properly tuned V8 and Mercedes has resisted the temptation to quieten it down on the outside and generate a fake noise for the inside. Although that would be stupid in a convertible, if you think about it.

The SL63, despite its AMG badge, isn't about all-out handling, of course. The Ferrari California would definitely show it how it’s done on a winding country road. The SL is more about flow, building momentum and rarely shifting down to second gear. The monstrous torque is enough to keep things rolling but should you wish for a bit more of the exhaust bellow, second is there for the taking.

Hustling the big convertible feels wrong, not because it can't do it, but because it's not really what it's for. Having said that, it offers a kind of fun that nothing else on Earth will provide, not even a Bentley GTC.

With the roof up, the SL63 is a quiet place but not remarkably so. The huge sticky tyres do the cabin's hush no favours, with an annoying roar on a wider range of surfaces than you might expect.

Roof down, it's hardly a paragon of virtue. A lot of wind noise reaches the cabin, even well below the huge speeds the SL can reach. So if you want to talk, it's windows up you'll need to deploy the mesh screen that bridges the roll hoops.

The Tiggo 8 leans into the traits on display in the smaller Tiggo 7. This means a too-high seating position trading driver ergonomics for visibility, a vague steering tune defined far too much by software, and an overly soft ride quality.

There are various trade-offs here, but it’s about the opposite of a driver’s car. The steering lends hardly any feel to what’s going on at the wheels, and the floaty ride conspires with the tall seat base to feel a bit disconcerting when cornering at high speed.

However, the positives include ease of use and relative comfort. The steering is light enough to make the Tiggo 8 pretty manoeuvrable at low speeds, and the soft ride has the Tiggo 8 floating over road imperfections with relative ease.

It’s also quick, with the electric motor providing urgent acceleration, but this is somehow not very engaging or fun regardless. Plus, slamming the accelerator down, particularly in Sport mode, will overwhelm the front tyres.

This car maintains over 20 per cent of its total battery capacity in reserve, in order to have a large buffer to draw from in hybrid mode to facilitate the smooth electric driving, but this also allows more room to store regenerated energy from idle time or braking compared to a plugless hybrid.

It seems to drive as an EV most of the time, although it lacks a true one-pedal driving mode despite having three levels of regenerative braking.

The cabin is impressively quiet, particularly at lower speeds. It’s genuinely hard to tell when the combustion engine is on to assist the electric driving functions, and the standard acoustic glass keeps most of the nasty ambient noise out. However, at speeds above 80km/h, road noise eventually finds its way into the cabin.

There are many rivals that provide an overall better balance of driving dynamics and handling with comfort, but this Tiggo 8 shoots for a more comfort-oriented family buyer who just wants a quiet and fuel-efficient SUV.

There’s plenty of safety kit for the Tiggo 8 with nothing left to options or based on grades.

The key stuff is present, including auto emergency braking (AEB), lane keep assist, blind spot monitoring with rear cross-traffic alert and braking, traffic jam assist, door open warning, a speed limit information system, and driver monitoring.

I bet you want to know if they’re well calibrated? After all, Chery’s Omoda 5 was slammed on its arrival for an infuriating lane assist system and overbearing driver monitoring, two of the most frequently offending systems for interfering with the drive experience.

I am pleased to report though these systems have been toned down significantly. Oddly, I found the driver monitoring system was fussier in the Tiggo 8 than the Tiggo 7, verging on being annoying, but it could have been the different road conditions we were on. The lane system on the whole was pretty tame, and the traffic sign alert was easy enough to tone down to a barely noticeable audible warning.

However, the lane centring software on the adaptive cruise was a bit frustrating, strongly tugging on the wheel if it disagreed with your interpretation of the centre of the lane.

It’s far from one of the worst systems in recent memory, and nice to see Chery take on the feedback and improve the cars with each release.

Plug-in hybrid versions of the Tiggo 8 are yet to be rated by ANCAP, but the combustion car was rated a maximum five-stars to the 2023 standards. The Tiggo 8 is equipped with nine airbags, however it is worth noting there is no child seat mounting system in either of the third-row seats. 

The SL63 is covered by Mercedes' three-year/unlimited kilometre warranty. And, er, that's it.

The Tiggo 8 Super Hybrid is covered by seven years and unlimited kilometres of warranty, seven years of roadside assist, and seven years of capped-price servicing, following the successful formula of once-underdog Kia.

The servicing price varies year on year according to the capped-price schedule, between $299 and a particularly expensive service at the 90,000km mark which costs $1291.31.

The average yearly cost works out to $453.45 if you keep the car for the full seven-year duration. Not the cheapest we’ve ever seen, but all things considered, it’s pretty good.
