Mercedes-Benz C250 vs Tesla Model 3

What's the difference?

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.

Tesla has done enough with the introduction of this Premium Long Range RWD variant to keep the Model 3’s head well and truly above water in an increasingly competitive segment. After more than six years it still looks good, with a pleasant cabin environment, plenty of performance and leading energy efficiency. Safety is top-shelf and it stands up well in terms of practicality and driving dynamics. 

That said, the ownership proposition is average, the determination to make so many functions screen-based is frustrating and the optional Full Self-Driving system is unconvincing. With the Model S and Model Y now discontinued globally it will be interesting to see how the Model 3 continues to evolve.

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. 

After four years in market, a heavily upgraded version of the Model 3 arrived in Australia in 2023, the biggest visual changes being a reshaped bonnet, aero massaged overall profile and angular slimline headlights.

The boot lid now incorporates a lip spoiler and the tail-lights were remodelled to create a truncated, two-layer effect. And in true Tesla fashion, the standard 18-inch alloy rims are fitted with matt black-finish aero elements filling the gaps between the satin black wheel spokes. Two new body colours - ‘Stealth Grey’ and ‘Ultra Red’ - were recently added to the available palette. For reference, our test car's finish is 'Quicksilver'. 

It’s still clearly recognisable as a Model 3, but these relatively minor design changes have helped the mid-sizer keep up with the slew of sleek newcomers it now faces.

The interior was also given a substantial makeover, the expansive 15.4-inch central display screen backgrounded by an all-new wrap-around dash and revised console treatment, the former featuring a raised insert and the latter a two-device wireless charging station.

Introduction of this Premium Long Range RWD model also brought the small but significant addition of a physical indicator stalk on the left-hand side of the steering column, replacing buttons on the steering wheel. Big ergonomic tick for that.

Customisable ambient lighting lifts the tone, soft materials look and feel good and the doorcards, bins and armrests have been reprofiled into a more sophisticated arrangement.

Our test car’s dark grey and white synthetic leather trim combination lifts the mood as does light from the huge, two-panel glass roof. But beware, while white trim looks dazzling on the showroom floor it takes some extra work to maintain its schmick appearance in the day-to-day grind.

After seven years in market the Model 3 has aged well and still looks sleek and contemporary.

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.

At just over 4.7m long, more than 1.8m wide and a bit over 1.4m tall (with a 2875mm wheelbase) the Tesla Model 3 is a low-slung medium-size sedan. 

There’s plenty of space up front, a feeling enhanced by the standard panoramic glass roof and our test car’s white trim brightening up the cabin.

There are long, wide bins on the front doors with enough room for large bottles, a slim glove box (which opens only via an on-screen button, which is annoying) and a generous lidded storage box between the seats that doubles as a centre armrest.

The console houses two cupholders with another storage cubby ahead of them (both with sliding covers over the top) and the dual device wireless charging bay on the lower part of the dash under the media screen.

Switching to the rear, at 183cm I have a surprising amount of foot, leg and headroom when sitting behind the driver’s seat set to my position. The rear door aperture is surprisingly large which helps entry and egress.

Technically able to accommodate three passengers, the back seat is best for two full-size adults on anything other than a mid-length journey, although the flat rear floor helps ease pressure on the centre occupant.

There's a well-hidden fold-down centre armrest with cupholders, there are useful bins in the doors and hard shell map pockets on the front seatbacks.

The crisp 8.0-inch rear screen is a welcome entertainment option for back-seaters and there are adjustable air vents underneath it.

For power and connectivity there are two USB-C ports and a 12-volt socket in the front compartment, a USB-A in the glove box (mainly for dash cam and ‘Sentry Mode’ data storage) and two USB-C ports in the rear under the vents.

Boot space is a ample at 682 litres (the bootlid is adjustable for opening height) with an 88L ‘frunk’ in the nose. And if you need to tow a relatively light load like a box trailer or Jet Ski (or two) you can hook up a 1.0-tonne braked trailer (750kg unbraked).

While we understand it helps maximise battery space and reduce weight, we’re not on board with Tesla’s policy of providing a repair/inflator kit rather than a physical spare tyre. Even though this is likely to be a primarily urban cruiser, it’s not good enough. 

Then, there’s the Tesla app, an electronic Swiss Army Knife that facilitates everything from remote vehicle access and cabin ‘preconditioning’ to planning your route (complete with charging stops) and monitoring Sentry Mode (checking the vehicle’s surroundings and receiving alerts of potential threats).

The list of functions goes on and on, but suffice it to say the app is hugely handy. For example, ‘Dog Mode’ keeps the air con on with the car locked for the benefit of your four-legged friend and lets passers by know the doggo is safe via a bold message on the central screen. An internal camera, accessible via the app, lets you check-in remotely, too. Nice. 

Given its overall size and despite its conventional sedan configuration, the Tesla Model 3 offers efficient packaging and a heap of thoughtful features to enhance everyday practicality.

At $61,900, before on-road costs in NSW ($67,329, drive-away), the Tesla Model 3 Premium Long Range RWD sits in the same price ballpark as other pure-electric mid-size sedans like the BYD Seal Premium RWD ($58,798, BOC), Hyundai Ioniq 6 2WD ($67,300, BOC), MG IM5 Platinum RWD ($69,990, drive-away) and Polestar 2 Standard range Single motor ($62,400, BOC).

Broaden the consideration set to include medium EV SUVs and a dozen other options including the BYD Sealion 7, Kia EV5, Skoda Enyaq and Zeekr 7X enter the picture, many with a price-tag around $10K lower than the Model 3’s.

But price is one thing, value is another. Aside from the performance and safety tech we’ll get to shortly, let’s look at the Model 3 Premium Long Range RWD’s included features.

Standard spec highlights include LED exterior lighting, new design 18-inch alloy wheels, a 15.4-inch central display screen, synthetic leather seat trim, power-adjustable ventilated and heated front seats, tri-zone climate control, adaptive cruise control and nine-speaker audio.

There’s also ambient interior lighting, navigation (with real-time traffic updates), an 8.0-inch rear touchscreen for back seat climate and entertainment, a power boot lid, dual wireless phone chargers, surround parking sensors, keyless entry and start (plus a lot more through the Tesla app, which we’ll cover in the Practicality section) and 360-degree acoustic glass (including the standard glass roof). Still no Android Auto or Apple CarPlay, though.

Add in less obvious improvements like the extension of soft-touch materials throughout the cabin and this Model 3 stacks up well in terms of value relative to its cost-of-entry and direct competitors.

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 Tesla Model 3 Premium Long Range RWD is powered by a single permanent magnet synchronous electric motor producing a handy 235kW and in excess of 400Nm.

It sends drive to the rear wheels only via a single-speed, direct-drive automatic transmission. 

Kerb weight is 1747kg and Tesla claims 0-100km/h acceleration in a rapid 5.2 seconds.

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.

Tesla claims a WLTP range of up to 750km for the Model 3 Premium Long Range RWD, the official EV term for which is… a lot. 

As mentioned earlier, at the time of the car’s local launch in October last year Tesla claimed it as the longest-range EV in Australia and at the time of writing nothing had arrived to change that.

Unlike the standard Model 3, which is powered by a CATL-sourced LFP battery, the Long Range RWD is fitted with a lighter, more energy dense NMC pack from LG with a total capacity of 82kWh (78kWh usable).

In terms of energy consumption, Tesla claims 12.5kWh/100km on the combined (urban/extra-urban) cycle and on test we experimented with liberal use of the accelerator pedal, higher than average freeway running and keeping the car constantly chilled during extremely hot weather, which resulted in an average of 15.7kWh/100km. 

Aside from that, more typical stop-start urban driving with occasional use of the ‘Chill’ (eco-focused) mode brings the number down to 13.1kWh/100km.

That’s an impressive performance, with even the upper test figure more than acceptable for a 1.75-tonne electric sedan.

Capable of accepting a 250kW fast charge, Tesla says the Model 3 Long Range RWD can take on 311km of range in 15 minutes, at that speed.

On a 150kW pylon we saw capacity go from 15-85 per cent (theoretically, 600km of range) in roughly 50min, although the charger fluctuated below peak output throughout.

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.

So, surprise, surprise, the Tesla Model 3 Premium Long Range RWD is quiet. But it’s quiet, even in the context of other EVs in this part of the market.

That’s thanks in part to acoustic glass in the front, rear and side windows as well as the dual-pane glass roof and the Bridgestone Turanza T005 EV tyres (235/45x18) featuring ‘B-Silent’ technology. Corny, but it works.

A kerb weight under 1.8 tonnes is relatively lightweight for an EV of this size and the Model 3 RWD is quick with 0-100km/h acceleration in a fraction over five seconds. There’s always plenty of pulling power under your right foot. 

Suspension is double wishbone front, multi-link rear and ride comfort is respectable rather than exceptional. Smaller bumps and irregularities find their way into the cabin but never to an alarming degree.

Steering sits in the middle-of-the-road between tactile and wooden, which is par for the EV course, although it's accurate and pleasingly progressive. Body roll, even in enthusiastic cornering, is modest. 

The physical brakes are ventilated discs front and rear although they don’t come into play all that often because the Model 3’s regenerative braking system is so good. Single-pedal operation soon becomes the norm. 

Our test car’s optional ‘Full Self-Driving (Supervised)’ will set you back $10,100 as a one-off payment, or $149 per month and Tesla says when using it, “Under your supervision, your car will be able to drive itself almost anywhere with minimal driver intervention”.

We engaged it for a 30km trip through suburbia, across the Sydney Harbour Bridge and into the city’s inner south. 

A rainbow-coloured magic carpet in front of the car graphic on the nav map tells you the system is engaged and although things went smoothly at first we soon sliced a bit off the inner oncoming lane as we turned right at a T-intersection, which was alarming. 

The system also has a consistent tendency to stick to the far right-hand side of the lane, stay five to 10km/h under the signposted speed limit and it continued to operate without my hands on the wheel, although I kept them there for 99.9 per cent of the drive (which is tiring when you’re not doing the steering).

Having been squeezed to the point where we couldn’t merge safely into a particular arterial road the nav took us on what’s known in the trade as a wild goose chase that had to be nipped in the bud. If I hadn’t known my way around it could have been a huge waste of time and (vehicle) energy. As much a nav issue as an FSD one, but overall, let’s just say, I’m not convinced.

Under the heading of miscellaneous observations, I’m not a fan of the on-screen gear position slider in place of a physical control. It’s needlessly fussy, although its ability to automatically switch between D to R (and back) during slow-speed manoeuvres is helpful. 

The software behind the car’s multitude of functions is exceptionally good, as is the ability to swipe in the vicinity of the temp and audio volume screen sliders, rather than having to hit them bang on and the blind-spot camera view which pops up on the screen when indicating on either side is handy.

The Model 3 has a maximum five-star ANCAP rating from assessment in 2025, with outstanding scores across the independent body’s four key pillars: Adult Occupant Protection - 90 per cent, Child Occupant Protection - 95 per cent, Vulnerable Road User Protection - 89 per cent and Safety Assist - 88 per cent. Wow.

Active (crash avoidance) safety ticks a heap of boxes including AEB (operational from one to 150km/h with forward collision warning covering cars, cyclists, pedestrians and motorcycles) as well as rear AEB, lane keeping assist (car-to-car and car-to-motorcycle), lane departure warning, blind-spot monitoring, a 360-degree camera view, driver fatigue detection and more. None of them are overly intrusive in operation.

The airbag count runs to seven - front head and front side as well as full-length curtains, and a front centre bag to minimise head clash injuries between driver and co-pilot in a side collision. There’s also multi-collision brake (to reduce the chances of subsequent impacts after an initial crash).

For baby capsules or child seats there are three top-tether points across the second row with ISOFIX anchors on the two outer positions.

A super-impressive safety package that matches or betters anything in the category.

Worth noting our test car features Tesla’s ‘Full Self-Driving (Supervised)’ functionality which we’re positioning as a convenience feature rather than an outright safety factor. So, its performance is covered in the Driving section.

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.

From January 1, 2026 all new Teslas sold in Australia have been covered by a five-year, unlimited kilometre warranty (including roadside assistance for the duration), up from four years/80,000km, previously.

A big step forward, no doubt, but that just gets Tesla to a base, mainstream market level with a dozen brands now at seven years, several at eight and three at 10 years (conditional).

The drive battery is covered for eight years/192,000km, which is in line with the category norm. And a Body Rust Limited Warranty covers rust perforation for 12 years, unlimited kilometres, which is reassuring.

Tesla servicing is condition-based, so there’s no fixed schedule, with a summary on the car’s touchscreen providing a record of when vehicle maintenance was last carried out and prompts for when they should be performed next.

In the absence of a combustion powertrain the emphasis is on things like wheel rotation, balancing and alignment, brake fluid testing, air-con servicing, camera precision, radiator cleaning and high-voltage battery maintenance.

Theoretically, if a workshop visit is flagged in the car’s system, it could include actions like a ‘Vehicle Health Check’ ($270), ‘General Diagnosis’ (270 per hour), brake fluid flush ($240.80) and replacement of both cabin air filters ($106.60).

Things like air-con desiccant bag replacement ($89.18), tyre rotation ($81.00), a wheels check - if tyre wear is abnormal ($81) and a wheel alignment ($225) are also set inspection and service items. All prices exclusive of GST.

In the States, the brand provides a range of estimated annual service pricing of between US$257 - US$499 ($367-$712), based on data collected by car buying specialist CarEdge. The suggested service range is around 20,000km and the first five annual estimates are at US$300 ($430) or less.

Tesla has 25 stores in Australia, not surprisingly covering mainly urban and larger regional centres, including four each in Melbourne and Sydney, three in Canberra, two each in Adelaide, Brisbane and Perth as well as one in Hobart.
