Lexus RC350 vs Mercedes-Benz C250

What's the difference?

If you’re a buyer that thinks with their head, the RC 350 F Sport is the obvious choice when compared to its direct rivals.

After all, it looks great (at least to these eyes), feels luxurious in more ways than one, and is unrivalled when considering value-for-money.

But, if you think with your heart instead, it’s clear it is isn’t on the same level dynamically and therefore doesn’t feel as sporty to drive as its name suggests.

So, don’t let its sports car classification fool you, the RC 350 F Sport is more of a grand tourer, or a comfortable cruiser, to be precise, and an underrated one at that.

Baby steps these might be, but they're important ones for Benz. The new in-cabin tech and clever engine in the cheapest models only strengthen the C-Class proposition, without taking anything away from the drive experience, cabin ambiance and utterly sublime ride.

In short, Mercedes' reign at the top of the premium mid-size segment is unlikely to be toppled anytime soon.

Looking at the RC 350 F Sport, it’s hard to imagine how it became so anonymous on the road, whether you love it or hate it.

Up front, its striking design simply cannot be ignored, with its unique mesh 'Spindle' grille insert demanding attention.

Either side of it are the LED headlights and boomerang-style daytime running lights, which, again, cannot be missed.

Around the side, the RC 350 F Sport has all the hallmarks of a classic coupe, including a swoopy roofline, and looks all the better for it.

The 19-inch alloy wheels wrapped in a mixed set of Bridgestone Potenza tyres are particularly arresting thanks to their sporty 10-spoke design.

That said, the rear end is arguably the RC 350 F Sport’s best angle, at least universally, thanks to its crisp LED tail-lights and chunky bootlid.

The bumper below is also a looker, even with its fake side air intakes, while its diffuser insert is flanked by a pair of chrome exhaust tailpipes.

Inside, the RC 350 F Sport isn’t quite as good, with most of our criticism directed at the 10.3-inch central display, which is powered by an average multimedia system made worse by an incredibly fiddly touchpad controller. The physical shortcut buttons on hand are but small mercies.

Thankfully, Apple CarPlay and Android Auto support is now standard, so a better user interface is literally in your pocket… but you still don’t have a touchscreen to work with.

The RC 350 F Sport’s button-controlled 8.0-inch digital instrument cluster is much better, even if it’s more like a multi-function display due to its limited functionality.

While the centre stack and console designs are undoubtedly showing their age, there’s no doubting this is a premium model thanks to the selection of high-quality materials used throughout the cabin.

In our test vehicle, black leather-accented upholstery with (very cool) 'Tuscan Sun' yellow accents, piping and stitching covers the sports steering wheel, gear selector, sports seats, armrests, door inserts, knee rests and the instrument cluster. So, almost every touch-point.

Pleasingly, soft-touch plastics are used for the upper and middle dashboard as well as the door shoulders, with hard plastics only found on the lower dashboard, door bins and rear seat divider.

As per other Lexus models, the RC 350 F Sport has nice rose-gold accents on its steering wheel, gear selector, front air vents and centre console, while specific Naguri aluminium trim adorns its dashboard and door inserts. And there are also steel pedals.

Perhaps not quite blink and you’ll miss them, but we're not talking radical changes either, folks. Benz tells us as much as 50 per cent of the C-Class components are new or changed, but it has clearly subscribed to the 'if it ain’t broke' philosophy in the design department.

Yes, there are new bumpers front and rear, new LED light configurations and new colours and wheel designs, but we’re not talking huge changes outside. Still, the C-Class cuts a fine figure on the road, what with its intricate alloys, bonnet-defining grille and simple, understated body contours. Australia will take every available body style, too, including sedan, coupe, cabriolet and - our personal favourite - the 'estate' station wagon.

The C 43 AMG now gets the twin-blade grille design used on the V8-powered models, as well as a two pairs of rounded exhaust tips at the rear.

Inside, though, the changes are more substantial. For one, the new-generation Mercedes Touch Control steering wheel arrives as standard, as does a new and very effective 12.3-inch screen that replaces the traditional dials in the instrument cluster (standard on every model). 

The cabin remains a peaceful and premium-feeling space, with a fine use of materials (including quilted leather on the door panels, polished silver or faux-wood for the centre console and leather for the steering wheel), and Benz deserves credit for ensuring that sense of luxury extends to backseat riders. 

Hope you’re not expecting the RC350 F Sport to be the first word in practicality, because it’s not.

Measuring 4700mm long (with a 2730mm wheelbase), 1840mm wide and 1395mm tall, the RC350 F Sport is a decently sized coupe, but that doesn’t mean it’s spacious. Hell, it’s hard to get into it the first place, let alone out.

We are of course referencing the token second row, which is cramped at best. In fact, behind my 184cm (6.0ft) driving position, there is no toe-room nor headroom. Yep, if you’re around my height or taller, get used to burying your chin into your chest.

Thankfully, legroom is better but still limited to less than two centimetres, while foot space is compromised by the unusually tall transmission tunnel. And in case you were wondering, even the first row is on the tighter side.

Beyond the central air vents, you’d think rear occupants would be cheered up with cupholders, a fold-down armrest and USB ports at the very least. Well, they don’t get any of that, with a couple of coat hooks the only amenities on offer.

And don’t forget that being a four-seater, there are only two seats in the second row, so this is definitely not a ‘family car.' That said, there are two ISOFIX and two top-tether anchorage points for child seats, so you can theoretically take a couple of younglings with you on a trip.

In-cabin storage options are very limited, with the glove box small in size and mostly taken up by the manual, while the central bin is useable but somewhat occupied by two USB-A ports, a 12V power outlet, and an auxiliary input.

And whatever you do, only bring up to two drinks with you, as beside the pair of cupholders next to the gear selector, there is no other place to officially store extras. Yep, the front door bins are only good for storing very short and narrow items.

The boot is a different story, with a decent 374L of cargo capacity, and it can be expanded by stowing the 60/40 split-fold rear bench, an action that can annoyingly only be performed in-cabin via the manual release latches.

That said, the boot’s tall load lip makes unloading bulkier items a little trickier, while getting them onboard in the first place is complicated by its wide but short aperture. At least there are four tie-down points on hand to secure loose loads?

It all depends, really. All C-Class variants sit on the same 2840mm wheelbase, and stretch 1810mm in width. The sedan, coupe and cabriolet versions measure 4686mm in length, while the Estate’s bigger cargo area increases its size to 4702mm.

Predictably, then, the estate offers the most useable (VDA) boot space, with 490 litres with the rear seats in place, swelling to 1510 litres with the rear seats folded flat. The sedan version is next on the cargo-carrying list, with 455 litres, followed by the 380 litres of the coupe and 285 litres of the cabriolet.

We spent our entire time in the four-door sedan models, and we can report a spacious and comfortable space for driver and passenger (you could play ping pong on the wide centre console) with two cupholders and room in each of the front doors for bottles. There’s all the USB and power connections you might need (most housed in a deep storage bin that separates the front seats) and the more expensive models offer wireless charging for compatible phones, too.

Climb into the sedan’s back seat, and you’ll find impressive legroom (behind my own 176cm driving position), but headroom - especially in sunroof-equipped cars - feels a little tighter. The rear seat is actually wide enough to fit three adults at a pinch, but the tall and bulky tunnel absolutely obliterates leg room for the middle-seat rider.

There are two cupholders in the pulldown divider that separates the backseat, as well two ISOFIX attachment points. Rear occupants also get there own air vents, as well as a 12-volt power source.

Mercedes is so far keeping mum on the details, ahead of the updated car’s arrival in August, but you can expect to see prices climb a little from their current levels ($61,900 - $100,611, and $120,642 for the C 43 cabriolet).

The C200 will retain 18-inch alloy wheels, artificial leather (and electric in the front) seats, nav, ambient interior lighting and keyless entry and push-button start, but critically adds a new 12.3-inch screen in the driver’s binnacle that replaces the traditional dials. It joins a landscape-oriented 10.25-inch centre screen - both now standard across the C-Class range - which propels the cabin into a clean and modern-feeling future.

The C220d and C300 features list will likely change little, but all get Mercedes’ new 'Touch Control' steering wheel, as well as new LED head and tail-lights, while the C 43 AMG 4Matic gets the best of Merc's autonomous driving technology. 

Expect more information to arrive around July.  The C 63 AMG is also due for updating, with a new model scheduled to arrive around December. 

The RC 350 is motivated by a lusty 3.5-litre naturally aspirated V6 petrol engine that produces 232kW of power at 6600rpm and 380Nm of torque from 4800-4900rpm.

For reference, the RC 300 uses a 2.0-litre turbo-petrol four-cylinder unit that develops 180kW at 5800rpm and 350Nm from 1650-4400rpm.

Either way, these outputs are exclusively sent to the rear wheels via a well-sorted eight-speed torque converter automatic transmission with paddle-shifters.

This combination helps the RC350 sprint from a standstill to 100km/h in about 6.1 seconds while on the way to its electronically limited top speed of 230km/h.

It’s here where the C-Class is at its most updated, serving up a new turbocharged 1.5-litre hybrid engine in the entry-level C200. Alone, it’s good for 135kW/280Nm, but it’s combined with a clever 48-volt system that adds up to 11kW of bonus power low in the rev range, happily plugging the power void usually left by turbo lag when taking off, or if you plant your foot when overtaking.

The C300 is powered by a more conventional 2.0-litre, four-cylinder good for 190kW/370Nm, while the sole diesel (in the C220d) is a four-cylinder unit that produces 143kW/400Nm. All are paired with a nine-speed automatic transmission.

The C 43 4Matic's engine remains a fabulous thing, only now tweaked for a little bit more power. It's good for 287kW/520Nm, and is paired with a nine-speed transmission that sends the power to all four wheels, albeit with a bias toward the rear tyres.

The RC350’s fuel consumption on the combined-cycle test (ADR 81/02) is 9.1 litres per 100 kilometres, while its carbon-dioxide emissions are 212 grams per kilometre, but both claims are a little keen.

In our real-world testing, we averaged 12.2L/100km, which is far cry from the above, given our result came from 180km of driving that was heavily skewed towards highway stints over city traffic.

For reference, the RC 350’s 66L fuel tank takes 95 RON premium petrol at minimum.

Let’s start with the C200, where the addition of the clever hybrid system has helped drop fuel use to a claimed 6.0-6.3 litres per hundred kilometres. The old car delivered 6.5 per hundred, but was slightly quicker from 0-100km/h (7.2sec- 7.7sec). 

The C300 will sip a claimed 6.5-6.9L/100km on the same cycle, while the diesel requires a miserly 4.7 litres. The C 43 is the thirstiest, of course, needing 9.1-9.3L/100km on the same cycle. 

The C200 makes do with a 41-litre tank (as does the diesel) while the C300 steps that up to a 66-litre tank. And all those numbers related to the sedan body shape, so expect some slight variations if you’re shopping for a coupe cabriolet or estate.

The RC350 F Sport is actually pretty good to drive – so long as you understand what it’s about.

Think of it more as a comfortable cruiser than a sports car and you’ll forgive it for some of its shortcomings. Yep, it is that relaxing to drive.

While the F Sport’s suspension (independent double-wishbone front and multi-link rear axles with adaptive dampers) does have a sports tune, it still serves up a comfortable ride on most surfaces.

Naturally you can play with the five drive modes (Eco, Normal, S, S+ and Custom) on hand to increase its stiffness and therefore improve handling, but the difference between soft and ‘hard’ is negligible, so don’t bother.

Either way, the F Sport does have a noticeable habit of picking up sharper road edges, such as nasty potholes, and it's particularly prevalent at the rear. That said, it doesn’t detract from its luxuriousness all that much.

Where the sportiness really comes to the fore, though, is via the F Sport’s electric power steering system, which has a variable ratio.

As well-weighted as this set-up is as standard, you’ll find it hard to forget how sharp it is on turn-in. Among several factors at play, the obvious one is the F Sport’s rear-wheel steering system, which is better executed than most.

This technology turns the front wheels in the opposite direction to the rears at lower speeds but in the same orientation at higher velocities.

The result of the former? A mid-size coupe that feels like it has a short wheelbase, with the improved manoeuvrability especially noticeable in car parks. Conversely, the latter lends itself to greater stability when you need it.

And it’s a good thing it is the way it is, because the RC 350 F Sport has a kerb weight of 1740kg, which is not exactly sports-car light. This heft is a felt when cornering hard, even though body control is pretty strong overall.

Handling performance is also enhanced by the rear Torsen limited-slip differential, which helps improve grip upon corner exit, at which point the RC 350 gets to show off its straight-line abilities.

The V6 engine is buttery-smooth, but you really need to stick the boot in to fully enjoy it, with it only really starting to come alive when engine speeds are above 3000rpm.

That said, it’s easy to appreciate this character trait around town, where the RC 350 is truly unfazed. Take it onto the open road, though, and acceleration is more than pleasing.

The automatic transmission is a great dancing partner here, serving up delightfully smooth gear changes. It’s also surprisingly responsive, perhaps too responsive, as it can be quite fussy in city traffic, shuffling up and down ratios in quick succession.

Biggest gripe, however, is the digitally enhanced sound the RC 350 produces. Sitting inside, the noise being pumped in is satisfying, but you can’t help but acknowledge the aural deception at play.

Keen to sample the new hybrid tech in the C200, we made a beeline for the cheapest C-Class. And if you’d told me, even a handful of years ago, that a piddly 1.5-litre engine would be enough to drag the 1555kg Benz around, I’d have labelled you crazier than Donald Trump's Twitter account. 

The C200’s system is a unique hybrid set-up, in the sense that it only delivers extra power in the tiniest of circumstances, but they’re the areas that it really needs it. From a standstill, the electric motor delivers its extra 11kW of oomph at just the right moment need to help get you moving (the same when overtaking) and it does genuinely make a difference. 

It can’t completely overrule the concrete laws of physics, though. Plant your foot on anything that even looks like a hill and you can definitely hear that 1.5-litre engine working hard - interrupting the ambience of the cabin - but keep it in the sweet-spot of the rev range and it’s a quiet, capable-feeling engine that delivers more punch than its size might suggest.

On Germany’s epic autobahns, the needle even sailed past 215km/h without too much encouragement (even if I could have knitted a sweater in time it took to to close the last 10-or-so-kilometres). Is that relevant for Australia? Sadly not, but it does suggest the engine is more capable than we will ever need it to be.

Elsewhere, the not-too-different C-Class rides an absolute dream, smooth-sailing over bumps and road imperfections, and the cabin is serene and comfortable - though there was more wind noise at times than I was expecting.

Downsides? Well, the cheapest C-Class doesn’t feel the most dynamic offering, with the light steering serving up a slight disconnect between the steering wheel and the road below in its most comfortable settings. Switching to Sport improves matters, but if you’re life is mostly city and suburbs, it will matter little.

The nine-speed transmission can behave oddly at times, too; smooth and lightning fast as it climbs the gears, and mostly perfect on the way back down. But I noticed a definite thump occasionally as it shifted down from second to first gear, which stripped a little refinement from the drive experience.

It's more noticeable in the C 43 4Matic AMG, but it's vastly overshadowed by the thick and meaty power delivery from that stonking turbocharged engine. It's a rocket, and while it's not as fast or as loud as its C 63 big brother, I honestly think the tweaked C 43 is all the AMG I'd ever need.

Detailed specifications for Australia are still being finalised for the C-Class, but we don’t think the standard safety equipment will change much.

So expect a comprehensive suite of airbags (including front, front-side, head for the first and second rows and a driver knee bag), joined by the usual kit of traction and braking aids on the C200. Blind-spot assist, tyre-pressure monitoring and AEB - part of the Collision Prevention Assist Plus package - also arrive as standard. 

Higher trim levels will nab active cruise, with stop and go, rear cross-traffic alert, active blind-spot monitoring system and active lane keep assist, while the C 43 scores Mercedes' most advanced auto-driving tech.

As with all Lexus models in Australia, the RC 350 comes with a four-year/100,000km warranty and four years of roadside assistance. Both offers are a year behind that of fellow premium brands Mercedes-Benz and Genesis.

The RC 350’s service intervals are every 12 months or 15,000km, whichever comes first. A three-year/45,000km capped-price servicing plan is available, costing $495 per visit, which is not too bad at all.

While specific maintenance pricing is yet to be confirmed, each of these models is covered by three-year warranty, with service intervals pegged at 25,000km or 12 months.
