Lexus Rx450H+ vs Mercedes-Benz C220

What's the difference?

The new Lexus RX450h+ Sports Luxury is packed with a wealth of premium features and strikes a solid balance between refinement and practicality. There are enough thoughtful touches that make everyday driving a little easier.

You’ll get the most out of the plug-in hybrid powertrain if you’re able to charge it regularly; ideally every day. That might not always be practical for busy people on the go, but overall, the RX450h+ manages to blend efficiency with Lexus’ signature comfort and quality.

This may well be just an update to the C-Class, but the changes made are significant in terms of technology and performance, and you’re paying hardly any extra money for it. A good all-rounder for dynamics, features, refinement and value.

The sweet spot in the range has to be the C 300. It’s less than $10K more than the entry grade C200, but gets a powerful 2.0-litre engine, leather seats, the extra advanced safety equipment, tinted windows and convenience features such as a power tailgate (on the wagon) and proximity unlocking.

The RX isn’t breaking new ground with its plug-in hybrid design, but it still delivers that signature Lexus understated refinement.

The strong, flowing body lines, 21-inch alloy wheels and updated 'spindle grille' all give it presence without screaming for attention.

And in a segment where boxy and bulky designs tend to dominate, the RX’s swoopy silhouette helps it stand apart in all the right ways.

Inside, the cabin feels considered and luxurious. There's a heavy use of premium materials, including the leather and suede upholstery, plush soft-touch surfaces and the big, crisp displays that make the space feel modern and high-end.

The panoramic sunroof brings in loads of natural light, too, which is especially welcome given the dark headliner that might otherwise feel a little heavy.

If I have one gripe, it’s the thin steering wheel, which doesn’t quite match the otherwise solid, tactile feel of the rest of the interior. But overall, the cabin is a space that feels luxurious and well-executed. It's quietly confident, just like the RX.

Now, to spot the difference between the new and the old C-Class from the outside just look at the headlights – the shape of the fitting is the same, but the new standard headlights on the C 200, C 220 d and C 300 have an LED set-up which looks like teeth, while the optional units (standard on the C 43 and C 63 S) are also LED but with a tall staggered design. Tail-lights also keep the same shape but with a different LED pattern, too.

The front and rear bumpers have also been restyled for all grades and the C 43 and C 63 S have had their grilles updated, with the former getting a new twin-louvre design, while its big brother now has chrome vertical slats reminiscent of the grille worn by the 1952 Carrera Panamericana winning 300SL.

The AMG Line Exterior package is standard on the Coupe and Cabriolet, but if you option it on the sedan it will fit a sports body kit with AMG front spoiler and side skirts.

The C 43’s gloss black rear diffuser looks tough with the new quad exhaust and the car in wagon form wins my award for best looking of the C-Class bunch.

Cabins haven’t been overhauled but they have been updated with a 10.25-inch dash-top display for media and a 12.3-inch fully digital instrument cluster - both are standard across the range and make a big styling impact in the cockpit. Mercedes-AMG grades have their own sporty version of the virtual instrument cluster.

The layout of controls remains the same, but you can now option a new real wood veneer to the centre console with 'open-pore brown walnut' and 'open-pore black ash' being your choices.

The Artico upholstery in the C 200 looks and feels ‘plasticky’. I’d option the real leather which comes standard on the C 300.

New to the C 43 are the optional ‘Performance’ seats with integrated head restraints and standard on this grade is a new leather AMG steering wheel. Other cool cabin features are the stainless-steel pedals, the AMG floor mats and stitched dash (even if it is Artico upholstery).

All grades now come standard with the 64-colour ambient lighting system. You should see the system fading through the colours at night and with the right music the whole effect is amazing.

The C-Class comes in four body styles: Sedan, Coupe, Estate (wagon) and Cabriolet.

Exterior and interior dimensions stay the same, all variants measuring about 4.7m in length. That’s a good size; not too big or small, making parking and manoeuvring in tight spaces pretty fuss-free.

The C-Class is made in various parts of the world, but I can tell you the C 200 Sedan we get in Australia is made at Mercedes-Benz's East London plant on South Africa's east coast.

The RX cabin is thoughtfully laid out and impressively practical, with a premium feel that doesn’t come at the cost of everyday usability.

Up front, there’s plenty of space for driver and passenger, yet the stepped dash design brings a sense of intimacy. The electric front seats are seriously comfortable, with four-way lumbar support and extra adjustment functions that make this an easy choice for long drives.

Storage options are generous, too. There’s a clever dual-opening centre console, large glove box, multiple phone-sized shelves, map pockets and a couple of cup- and drink holders in each row.

Charging is taken care of by four USB-C ports, one USB-A port and a wireless charging pad.

Tech is up-to-date and well-integrated. The upgraded 14-inch media display looks crisp, supports wireless Apple CarPlay and Android Auto, and is paired with a revamped 12.3-inch digital instrument cluster and a colour head-up display.

The cluster’s new layout is modern and much easier to read than the previous offering. The digital rear view mirror also earns its keep when the cabin’s packed with passengers or gear.

One of my favourite touches? The seat controls on the side of the front passenger seat. It makes quick work of moving the seat forward, especially helpful when you’ve got a kid clambering in with a school bag full of projects.

Access to the rear row is easy, but the stadium-style seating, where you're perched noticeably higher than those in the front, won’t be for everyone.

That said, the rear seats are plush and padded, though they lack side bolsters, which rear passengers might notice during cornering.

Legroom is generous and the hardened kickplates are a dream to clean when your child’s treating the seatbacks like a climbing wall.

My eight-year old gives the back seat a glowing review, thanks to its creature comforts, including rear climate control, directional air vents, seat heating/ventilation on the outboard seats, two USB-C ports and retractable sun-blinds, which are a crowd favourite in our household.

There are three top-tether anchor points, and the bench is wide enough to fit three child seats, though bulky booster seats might be tricky due to the raised seating height.

At the back, the boot is well set up for families, offering electrically folding rear seats, a 12-volt socket, flat loading floor, and a hands-free powered tailgate.

Under the floor, there’s a small compartment for your charging cables (Lexus throws in two!) and a usable 612L of capacity when all seats are in use. One downside, though, is the lack of a spare tyre as you just get a tyre repair/inflation kit.

This depends on the body style, but being a mid-sized car practicality can be limited, but Mercedes-Benz has been clever with the way it has used the available space.

The boot, for example in the C 200 is 434 litres, which isn’t as big as the cargo space offered by the BMW 3 Series or the luggage capacity of the Audi A4. This is partly because the hybrid system uses space under the bonnet, so the car’s battery needs to go to the boot.

The C 300 doesn’t use the hybrid system and so the sedan in this grade has 455 litres of boot space.

Choosing the C 300 Coupe’s will reduce your luggage carrying ability to 380 litres and the C 300 Cabriolet’s cargo capacity varies from 360 litres with the roof up and 285 litres when it’s down and eating into the luggage area.

The Estate is the best luggage hauler but it’s still not enormous – the C 43 Estate that we test drove has a cargo capacity of 480 litres.

Legroom in the back of the C 43 Estate is good and at 191cm tall I can sit behind my driving position with about 20mm to spare thanks to the sculpted seat back.

Headroom is getting tight in the Estate and especially in the Sedan – well for me, anyway – and the optional sunroof will lower the ceiling height even further.

Up front space in the Sedan and Estate isn’t an issue with plenty of head-, leg- and shoulder room offered.

Storage throughout the Sedan and Estate is good with a large centre console storage bin, two cupholders up front and another two in the back along with a storage area in the fold down armrest, but all four door pockets are on the slimmer side. Still they can fit a small bottle of water, plus a wallet or purse.

That centre console bin houses two USB ports, and a 12-volt outlet can be found in the storage area under the climate controls – which also houses the optional wireless charging pad. Without the charging pad that small area is too tiny to place my iPhone8 Plus.

Rear headroom and legroom in the four-seater Coupe and Cabriolet is limited, but both get a pair of cupholders in the back and two more up front.

The range kicks off with the C 200 and its C 220 d diesel siblings, then steps up to the C 300. Prices for these grades have increased by $1500 in this update but you’re being given more features. Above the C 300 live Mercedes-AMG’s wild animals – the C 43 and C 63 S.

The C 200 Sedan now lists for $63,400 (plus on-road costs), and if you want the Estate version add another $2500, and an extra $4500 for the Coupe, while the Cabriolet is $25,000 more at $88,400.

The C 220 d Sedan lists for $64,900 and the only other form it comes in is the Estate for $67,400.

The C 300 Sedan lists for $71,400, the Estate is $73,900, the Coupe is $84,900 and the Cabriolet is $101,900.

The C 43 Sedan lists for $107,900, while the Estate is $110,400, the Coupe is $111,900 and Cabriolet is $124,900.

The C 63 S Sedan lists for $159,900, however, prices for other body styles have not yet been announced.

So, about all the stuff you’re receiving in return for the price increase – a 10.25-inch display screen replaces the smaller one in the previous car and it’s standard across the range. Don’t stab and poke at it like I did with my finger for hours, because it’s not a touchscreen.

Also new is the 12.3-inch fully digital instrument cluster, and it’s standard on all grades, too. Apple CarPlay and Android Auto come on all C-Class cars.

Other standard features, starting with the C 200 and C 220 d, include 'Artico' upholstery, which is a synthetic attempt at leather, a reversing camera, shifting paddles, dual-zone climate control, aluminium roof rails on the Estate, LED headlights, 64-colour ambient lighting and 18-inch alloy wheels.

The C 300 has the C 200’s features and adds leather upholstery, privacy glass (coupe only), proximity key and 19-inch alloys. The C 300 also gains the 'Driving Assistance Package' which I’ll tell you all about in the safety section below.

The C 43 picks up the C 300’s equipment and adds an enormous list of its own gear including a new AMG steering wheel, brushed stainless steel pedals, Burmester 13-speaker stereo, heated sports front seats, head-up display, wireless charging, intelligent LED headlights, panoramic sunroof, black roof racks on the Estate, analogue clock and 19-inch AMG alloy wheels.

Metallic paintwork is also part of the C 43’s standard features list which includes 'Obsidian Black', 'Iridium Silver', 'Mojave Silver', 'Cavansite Blue', 'Emerald Green' and 'Brilliant Blue', but you’ll have to pay for 'Hyacinth Red', which is a sort of candy apple red. Non-cost colours for the lower grades are non-metallic black and 'Polar White' non-metallic.

The C 63 S adds to the C 43’s equipment list with its own AMG steering wheel, illuminated door sills, digital TV tuner, nappa leather upholstery, an electronic rear differential lock, 19-inch alloys in matte black with high-sheen rim, plus high-performance brakes with red calipers.

Under the bonnet the RX450h+ Sports Luxury runs a plug-in hybrid powertrain that pairs a 2.5-litre four-cylinder petrol engine with a CVT auto and dual electric motors - one on each axle. Together, they produce a total of 227kW of power, though Lexus doesn’t quote a combined torque figure.

Still, it’s quick off the mark for a large SUV, with a 0-100km/h time of 6.5 seconds. There’s more than enough grunt for daily driving and overtaking, even if it doesn’t quite match the outright power of its key PHEV rivals.

The previous C 200’s 2.0-litre 135kW/300Nm four-cylinder petrol engine has been swapped for a 135kW/280Nm 1.5-litre four-cylinder turbo-petrol with what Benz calls a ‘mild hybrid’ function.

This isn’t a hybrid with an electric motor driving the wheels, it’s an electrical system which is able to provide an additional 10kW/160Nm when accelerating. Known as the 'EQ Boost', the system also allows the C 200 to coast at a constant speed if the driver takes their foot off the accelerator. The battery is then re-charged when braking.

The C 220 d offers a diesel alternative and its new 2.0-litre engine now makes 18kW more power at 143kW and the same 400Nm of torque.

The C 300’s 2.0-litre turbo four has had a 10kW increase, taking power to 190kW, while peak torque is still 370Nm.

Also getting a power bump is the C 43 and its 3.0-litre V6 petrol is now good for 287kW (up from 270kW) while torque stays at 520Nm. The C43 uses Mercedes-Benz’s '4Matic' all-wheel drive system, while every other grade, including the C 63 S, is rear-wheel drive.

The C 63 S still makes an impressive 375kW and 700Nm.

The C 200, C 220 d, C 300 and C 43 all use the same nine-speed automatic transmission, while the C 63 S uses a ‘AMG Speedshift 9G’ which is a nine-speed dual-clutch auto.

The plug-in hybrid system brings solid efficiency, with claimed fuel use of just 1.3L/100km. In real-world conditions (mostly urban driving with regular recharging) I managed a respectable 4.8L/100km, which makes a strong case for the hybrid set-up.

The fuel tank holds 55 litres and it's worth noting Lexus recommends using a minimum of 95 RON unleaded petrol to fill it.

Using our real-world economy figure you can expect a range in excess of 1100km between fills.

The RX450h+ is fitted with a relatively small 18.1kWh lithium-ion battery, supporting an NEDC electric-only range of up to 65km.

While that’s fine for short daily trips, it’s shorter than you'd ideally want in a family SUV of this size and it lags behind rivals like the BMW X5 and Volvo XC90 in this department.

Charging is simple enough. The RX uses a Type 2 charging port and accepts up to 7.0kW on AC power, which means a full charge takes around 7.5 hours, perfect for overnight top-ups. Lexus also includes an at-home charging cable and second adapter cable as standard, which is a thoughtful touch.

Fuel consumption obviously depends on the engine, but did you know the body type also affects mileage?

Mercedes-Benz says the C 200 Sedan uses 6.4L/100km over a combination of open and urban roads. The trip computer in our C 200 Sedan recorded 7.1L/100km after 254km of mainly country roads.

The C 200 Estate according to Mercedes-Benz will need 6.5L/100km, the C 200 Coupe uses 6.4L/100km and the C 200 Cabriolet will need 6.8L/100km.

Mercedes-Benz is yet to announce the C300’s fuel consumption figures.

The C 220 d Sedan is frugal with diesel fuel consumption being 4.7L/100km, while the Estate version needs 4.8L/100km.

Mercedes-Benz is yet to announce the C300’s fuel consumption figures.

The Mercedes-AMG cars are the thirstiest with the C 43 Sedan using 9.4L/100km, and the Estate will use 9.6L/100km. After 286km of country roads the trip computer in our C 43 Estate was reporting an average consumption of 10.3L/100km. The Coupe economy is 9.5L/100km and the Cabriolet needs 10.0L/100km.
 
The C 63 S Sedan puts it away at the rate of 10.4L/100km, and the Estate’s usage is 10.7L/100km, while the Coupe and Cabriolet’s fuel efficiency is yet to be announced.

The RX450h+ delivers power that’s pert and prompt, with genuine bursts of acceleration that make driving fun. It’s always ready to go and there's no lag in stop-start traffic - which gives it a lively, dynamic feel around town.

The transition between petrol and electric power is seamless; you hardly notice the switch, which makes for a smooth, refined driving experience. The cabin is impressively quiet, even on the highway, making long trips comfortable and peaceful.

Regenerative braking isn’t adjustable and is subtle enough that many won’t notice it which is likely a plus for fans of traditional internal combustion engines who are making the PHEV leap.

The adaptive variable suspension adds a sporty edge to handling, letting you confidently take corners at speed. There’s some body roll but the RX never feels top-heavy or unsettled.

The steering carries the weight of the SUV but remains well-balanced and responsive. Overall, it’s a well-tuned machine that’s a pleasure to drive.

Maneuverability is a strong suit, too, thanks to a tight 11.8-metre turning circle and a clear, easy-to-use 360-degree camera system. Parking is easy-as-pie, which a lot of drivers will appreciate.

The Australian C-Class launch gave us the opportunity to drive the C 200 Sedan and C 43 Estate on a test route stretching from Melbourne's Tullamarine airport, roughly 300km north to Milawa in Victoria’s alpine region and back, with the conditions being dry and cool.

I knew the C 43 would be ridiculously fun, but you can’t eat your dessert first, right? So, I started in the C 200, which is far from just meat and three veg – it’s refined and enjoyable to drive.

Steering is well weighted and accurate, offering a better sense of connection to the road compared to some of its prestige rivals. The steering wheel itself felt good to hold, too – and this is on the base car.

The test car wasn’t without its options though and it did have the 'Dynamic Body Control Suspension' with its Comfort mode softening the dampers for a more compliant ride and the Sport setting for better handling.

And that ride was comfortable. The only disturbance to the serenity (we did go through Bonnie Doon) was a bit of wind noise created by what sounded like the wing mirrors.

Apart from that, the experience was serene – those seats up front are comfortable and supportive even after hours, the vision all-around is excellent and then there’s the engine, which is perfectly adequate.

Okay, 1.5 litres sounds small but the output is almost the same as the previous 2.0-litre and the 48 Volt EQ Boost hybrid system does provide just enough of a kick to get you away from the traffic lights or overtake without any discernible lag.

The hybrid system's coasting function is excellent – take your foot off the accelerator and your revs drop to zero but the car will maintain its speed. When you brake the battery is recharged so you’ll have the extra grunt again when you need it.

Now for dessert. Just idling the C 43 sounds sedate, but that’s with the exhaust note and engine in the Comfort setting. It means you can pull into your street at night or start it up early in the morning without waking the up the entire neighbourhood.

The C43 isn't as vicious as the V8 C 63 S, but that’s the appeal of it.

Or, to hell with them, the people next door are jerks anyway: put it in Sport and the twin-turbo petrol V6 snarls and crackles as you shift through the gears. It’s not as vicious as the V8 C 63 S, but that’s the appeal of the C 43 – it’s a milder form of wild that’s easier to live with, but still so much fun.

The back roads from Milawa to Mansfield were a great testing ground for the C 43 Estate with their hill-climbing bends and downward forest runs. Merc AMG claims the C 43 can accelerate from 0-100km/h in 4.7s, and while that’s more than half-a-second behind the C 63 S, it’s still plenty quick.

With fantastic turn-in, all-wheel drive offering superb traction and great grip from the Continental ContiSportContact rubber (225/40 R19s front, 255/35 R19 at the back), a smooth-shifting nine-speed, impressive brakes and that turbo V6 which pulled the car heroically out of corners, it was hard not to grin like an idiot.

Only my mouth hurt afterwards, not my body. There’s a line you’re not going to read in any other car review. Some sports cars have a ride so firm, and seats so hard, and driving positions with hip points so low, that I almost have to leave the vehicle on all fours.

But only my face hurt from smiling so much – you could pilot a car like the C 43 until it ran out of fuel from a full tank and still feel comfortable – which is almost what we did. How much fuel did it use? Keep reading to find out.

The C-Class was awarded the maximum five-star ANCAP rating when it was tested in 2014. The base grade C 200 is fitted with nine airbags, AEB which works most effectively at lower speeds, and blind spot warning.

Stepping up to the C 300 brings the 'Driving Assistance package' which adds a more sophisticated AEB with cross traffic function and evasive steering, plus lane keeping assistance.

No spare tyres here. The C 200, C 220 d and C 300 all come with run-flat tyres, while the Mercedes-AMG grades have a puncture repair kit.

For child seats, you’ll find two ISOFIX points and three top tethers across the back row of the Sedan and Estates, while the Cabriolet and Coupe have two ISOFIX points in the back.

There are also two hi-viz vests in the cargo area and, yes, you do get a warning triangle, too.

The RX comes with a five-year, unlimited-kilometre warranty, which matches its key rivals but isn’t exactly class-leading by today’s standards.

Servicing is handled via a capped-price program, with each service costing $695. The intervals are well spaced at every 12 months or 15,000km, whichever comes first.

This Sports Luxury grade also includes a three-year complimentary 'Lexus Encore' membership, granting access to a handy phone app and member benefits at partners like Westfield and Ampol. On top of that, you get 24/7 roadside assistance for added peace of mind.

The C-Class is covered by Mercedes-Benz’s three-year/unlimited kilometre warranty. We’re keen to see Mercedes-Benz move to longer warranty periods as is becoming the norm with mainstream brands, many of which are offering five year coverage.

Servicing is recommended at 25,000km/12-month intervals for the regular C-Class cars and the C 43. The C 63 S needs servicing every 20,000km or annually.

It’s great to see Mercedes-Benz offers capped price servicing. For example, the C 200 will cost you $396 at its first service, the second is $792 and the third is also $792.
