Lexus RZ450E vs Mercedes-Benz CLA200

What's the difference?

There are sportier EVs out there, there are more tech-savvy EVs out there, but few adhere to the luxury promise quite like the Lexus RZ, particularly at its price point.

It’s this primary characteristic which sets the RZ apart from the pack for me, and while it might not be for every first-time EV adopter, it nails the brief for the existing Lexus buyer while providing a ‘luxurious’ alternative to many of its firmer, sportier and less approachable rivals.

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.

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

I don’t think the RZ will be for everyone, but it has some very cool details and interesting angles, regardless.

It maintains the signature Lexus face, but this time has sunk the ‘spindle’ pattern deep into its plastic grille, making for a clean nose, but perhaps one which is a little too blank for some. No doubt it needs this smooth look to maintain as low a drag coefficient as possible.

Closer inspection reveals clever detailing, like the way the spindle pattern fades into the corners, and the whole look is lifted by how wide the car is. 

Sports Luxury versions are lifted further with contrast panels accentuating the width and shape.

My favourite angle of the RZ is the rear three-quarter. The coupe window line, split spoiler design, and cool strip tail-light, complete with three-dimensional Lexus branding, looks as contemporary as it gets, not to mention sportier and more intriguing than even some of its rivals.

Savvy EV buyers might know the RZ shares its platform and overall shape with the upcoming Toyota bZ4X and its Subaru Solterra spin-off, and while those two cars look near-identical from the outside, Lexus has clearly had a lot more creative licence with the design of its take on the formula.

Inside is perhaps where this car feels the most Lexus, however. The interior design is almost entirely unrecognisable when compared to the bZ4X, with Lexus going to town with its curvy, intricate design language, and plush detailing throughout.

Padded synthetic leather trims, which match the seats, adorn the doors, which are swapped out for ultrasuede in the case of the higher-grade Sports Luxury.

And Lexus has opted for a deep-set digital dash and massive touchscreen in place of the small column-mounted screen and tablet multimedia of its Toyota and Subaru relations. 

Everywhere you look, though, there’s attention to detail, with interesting material choices from the wacky carpet to the detailing on the centre console and in the door cards. It’s unmistakably Lexus, and feels premium.

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.

The RZ benefits from its electric-from-the-ground-up 'e-TNGA' platform, which offers an almost flat floor, wide, spacious cabin (despite its coupe-look rear) and there are plenty of clever touches throughout to enhance practicality.

The doors each offer a pocket with integrated bottle holder up front, there’s a wide centre console with a set of large bottle holders, and the clever dual-hinged armrest console which appears in other Lexus products, and a large bay under the multimedia unit which houses additional storage alongside the wireless charger.

Interestingly, the RZ doesn’t have a glove box on the passenger side, as this area is reserved for the infra-red projector in the Sports Luxury grade. 

Instead, the car has a cutaway underneath the bridge-design centre console for additional storage. It’s a welcome and surprisingly large area which also houses a 12V power outlet. However it’s a little tricky to reach when seated up front.

Adjustability feels good for the driver with decent leg and headroom, alongside a tilt and telescopic steering column.

There are dials for the climate controls and a centre dial for the volume adjustment, although there are still many functions - from drive mode to essential safety toggles - that are buried more than one menu deep in the touchscreen, and therefore a little clumsy to jab at while you’re driving.

The back seat offers excellent space for someone my size. At 182cm tall I had leagues of knee room and decent headroom, and of course all the soft trims continue. 

Bottle holders appear in the doors and drop-down centre armrest, and rear passengers score dual adjustable air vents and two USB-C power outlets. 

There are map pockets on the back of the front seats, and the higher-end Sports Luxury grade offers dual heated seats and a separate fixed sunroof panel for the enjoyment of rear passengers.

One interesting piece, however, is the high floor. Designed to facilitate the batteries, the high floor means you feel tilted back in the rear seats, like your knees are far off the ground.

The boot, meanwhile, is also surprisingly spacious given the raked rear window. At 522 litres it outranks most mid-size SUVs, and while it seems deeper than it is tall, it should be more than sufficient for the airport run or trips to the local Golf course.

An underfloor storage area is convenient for the stowage of your charging cables.

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.

In Australia the CLA 200 weighs in at $59,500, before on-road costs, which is plenty, but the all-wheel drive CLA 250 ($68,800) will join it early in 2020, so the range will line up against the likes of BMW’s 4 Series Gran Coupe, even the Audi A5 Sportback.

The Mercedes-AMG CLA 35 ($83,400) arrives before the of 2019, with the full-fat CLA 45 S scheduled for Q1 2020 (estimated circa $95,000).

For that $60K price tag the CLA 200’s standard features list includes, dual-zone climate control air, sports seats, ambient (interior) lighting, ‘Artico’ and ‘Dinamica’ trim (faux leather and suede, respectively), the twin 10.25-inch digital media and instrument screens (running the ‘MBUX’ interface), an AMG styling pack (including 18-inch alloy wheels), active cruise control, auto headlights, keyless entry and start, LED headlights, DRLs and tail-lights, a leather multi-function, flat-bottom sports steering wheel, sat nav, park assist (including a reversing camera), rain-sensing wipers, wireless phone charging, ‘Hey Mercedes’ voice control, and nine-speaker audio including digital radio as well as Apple CarPlay and Android Auto.

All CLAs can also be hooked up (via a smartphone app) to the ‘Mercedes me Connect’ remote connectivity system, allowing access to locking/unlocking the doors, tracking and locating the vehicle, retrieving maintenance and service information, and more.

For the record, our test example was loaded with five option packages, adding no less than $13,630 to the price tag for a total of $73,130. Specifically, the ‘AMG Exclusive Package’ ($3190) – Heated and cooled front seats, ‘Lugano’ two-tone leather upholstery (with contrast top-stitching), adaptive damping, and ‘Energising Comfort Control’, the ‘Communications Package’ ($2490) - Head-up display and  Burmester 590W, 12-speaker ‘surround sound’ audio, ‘Driver Assistance Package’ ($1790) – ‘Active Distance Assist’ (including ‘Cross-Traffic Assist’), ‘Driving Assistance package Plus’, ‘Lane Change Assist’, ‘Extended automatic Re-start’ (in traffic), and ‘Route Based Speed Adaptation’, and ‘Seat Comfort Package’ ($1290) - Electrically adjustable front seats, memory function for driver’s seat, exterior mirrors and head-up display (if fitted), heated front seats, and passenger mirror with reverse parking position, and ‘Vision Package’ ($2490) – ‘Adaptive Highbeam Assist PLUS’, ‘Multibeam’ LED headlights, panoramic electric sunroof, ‘Parking package HIGH’ (featuring 360-degree camera).

The RZ is only available with one powertrain choice, a dual-motor all-wheel drive set-up dubbed the 450e.

Unlike some systems, this dual-motor arrangement is far from symmetrical, with by far the majority of power sent to the front wheels.

Total system output is rated at 230kW/435Nm, consisting of 150kW/266Nm from the front, and just 80kW/169Nm from the rear.

Interestingly, this is significantly more punch than the Toyota bZ4X, further setting this Lexus apart.

The RZ uses a clever torque-vectoring system to make the most of this set-up when cornering, and debuts some interesting new tech like computer-balanced brakes to keep the car level under heavy deceleration as well as new adaptive pistons in the suspension to help the car adjust to different surfaces.

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.

Quoted range for the RZ is 470km, however this is to the more lenient NEDC testing cycle, as accepted by the Australian Design Rules. 

However, its real-world range is more like 400km, which is as it is more accurately measured to the WLTP standard.

The 71.4kWh battery pack is supported by a 150kW max DC charging speed, allowing a 10-80 per cent top-up in 30 minutes.

On a slower public AC charger, the RZ can pull a maximum speed of 11kW for charging in around six and a half hours, while single-phase charging, as you might get from a home wallbox system, at a rate of 7.0kW allows a charge time in around 10 hours.

Lexus throws in a public Type 2 charging cable, home wallbox installation, and a three-year Chargefox subscription (covering free fast charging) as part of an RZ purchase. Clever.

Officially the RZ consumes 18.7kWh/100km on the combined cycle according to the WLTP standard and I was surprised to find our car consumed 18.6kWh/100km during the test drive loop. 

For context, anything under 20kWh/100km is reasonably impressive in the premium EV space.

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.

Usually EVs, even premium ones, have a particular formula to the way they drive. 

Hefty, firm, and usually break-neck fast is the default position, with seemingly every manufacturer trying to remind buyers they too can be as fast as a Tesla.

However, the RZ breaks with the premium pack, offering a car which leans more into the luxury promise than maybe any other right now.

It’s a relatively serene space in the cabin, with notably limited wind or tyre noise, and a gentle steering tune which makes the car effortless to pivot into corners. 

This combines with the clever torque vectoring system, and lenient suspension to have the RZ simply wafting through corners.

The ride is interesting in that it is so far from the norm for the EV space. It is the opposite of firm and aggressive, with the car gently leaning into bends and barely feeling the texture of the road.

Small, rough bumps and high-frequency corrugations are dispatched with ease, the car simply floating over them, even when loaded up in corners, although, on the flip-side, longer undulations have it bouncing up and down a bit after-the-fact, perhaps a consequence of the doughy ride having to deal with the well-hidden weight of its batteries.

Despite efforts to deal with body-roll, there’s a notable amount, a consequence of the forgiving ride.

While these characteristics make the RZ a far more luxurious proposition on the road than many of its rivals, it is notable in how much it lacks a feel for the road. 

The steering is so electrically augmented it feels almost simulated, no matter which drive mode you select, and little of the road surface is communicated well to the driver. 

Even the brake pedal feels lifeless and distant, as it combines regenerative braking with the actual discs in a purely digitised progression.

The steering, acceleration and regenerative braking are all heavily altered by drive mode, with the car lacking a single-pedal drive setting, instead being fairly hands-off with the system. 

Some, looking for a particular EV drive experience, may be happy with this, others will appreciate how ‘normal’ the RZ feels in this department.

While the car feels disconnected in a sense, there’s no doubt the brakes work, the steering is effective, and it is deceptively quick. 

Its soft character might have you assuming it's slow, but a hot-hatch baiting 5.3 second 0-100km/h sprint time seems alarmingly achievable in the Sport mode.

One thing is for sure - everything described here is deliberate. Lexus has made a choice to go against the grain and do something different when it comes to the way this mid-size EV feels. 

To many existing Lexus loyalists, there will be a lot which is familiar, while providing a slice of the future, yet it might be far from the most engaging EV to drive. It certainly provides a gentler and more luxurious - if a little lifeless - alternative to the sporty status quo.

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.

It’s hard to fault Mercedes-Benz when it comes to safety, and the new CLA is loaded with standard active and passive tech.

Active safety tech includes ABS, BA, EBD, stability and traction controls, a reversing camera (with dynamic guidelines), 'Active Brake Assist' (Merc-speak for AEB), 'Adaptive Brake', 'Attention Assist', 'Blind Spot Assist' (with exit warning assistant), 'Cross-wind Assist', 'Lane Keep Assist', a tyre pressure warning system, a reversing camera plus ‘Parking Distance Control’ (front and rear), 'Traffic Sign Assist', a wet weather brake drying function, and ‘Active High Beam Control’.

If all that fails to prevent an impact you'll be protected by the 'Pre-Safe' accident anticipatory system, plus nine airbags (front, pelvis and window for driver and front passenger, side airbags for rear seat occupants and a driver's knee bag), and the 'Active Bonnet' automatically tilts to minimise pedestrian injuries.

There’s also an impact-sensing auto door unlock system, an auto emergency call function and crash responsive emergency lighting, plus a first-aid kit, warning triangle and (five) hi-vis vests in the boot are thoughtful additions.

The A-Class (which encompasses the CLA) was awarded a maximum five ANCAP stars in 2018, and for smaller occupants there are three child restraint/baby capsule top tether points across the back seat, with ISOFIX anchors on the two outer positions.

One of the key Lexus selling points is its ‘Encore’ ownership promise, which is at its best on its EV models.

For the RZ this includes a complementary 7.0kW home wallbox charger installation for those with garages, the inclusion of a wall socket and public Type 2 charging cables, a three-year Chargefox subscription keeping even your high-speed charging free for the duration.

The warranty is five years, unlimited kilometres, with roadside assist included.

Capped price servicing is available over five years, weighing in at $395 per 12 month or 15,000km interval, whichever comes first.

Lexus will also organise to pick up and drop off a loan vehicle at service time, while the high-voltage battery is covered by up to 10 years of warranty if the logbook is adhered to at an authorised Lexus workshop.

The brand also offers extra benefits through its ownership program, like deals at hotels and restaurants, as well as invites to events like track or golf days.

This is an impressive above-and-beyond suite of offerings befitting a premium brand, although it should be pointed out some premium EV rivals offer service intervals which are twice as long, and even free servicing for the entire warranty period.

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.
