Mercedes-Benz CLA250 vs Volkswagen Id.5

What's the difference?

The Mercedes-AMG CLA 45 S is more glorious madness from the hot-rodders in Affalterbach. A design and engineering master-class putting a slightly more mature spin on the fast and furious small AMG formula. But only slightly. It's brilliantly outrageous.

At long last, the ID.5 GTX arrives to make a different pitch than many of its electric rivals. Less about straight-line speed and more about refinement and handling, this EV mid-sizer makes a case for itself, even if it’s not as good value as its ID.4 sibling.

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

Claimed to blaze from 0-100km/h in 4.0 seconds the second-generation CLA 45 has the performance credentials of a mid-engine supercar, wrapped in a relatively unassuming three-box body. And while it might look mild-mannered from a distance, this devil's differences are in the detail.

Like it's A 45 sibling the CLA 45 S features AMG's now signature Panamericana grille with 12 vertical louvres, a winged front spoiler treatment, extra aero bits around the front air intakes and 'Power Dome' bumps in the bonnet.

The side skirts are wider, and the 19-inch twin five-spoke rims are standard. While at the back the diffuser treatment is more pronounced than the hatch, but the fat 90mm exhaust pipes are the same, and the lip spoiler is on the boot lid rather than the roof.

The interior is virtually identical to the hatch, the biggest difference being the four-door coupe's frameless doors.

A combination of Merc's 'Artico' faux leather and 'Dinamica'  microfibre trim is accented with racy yellow highlights, with a nappa leather and Dinamica AMG Performance wheel and sports pedals completing the picture.

And the twin widescreen MBUX instrument and media display boasts AMG-specific read-outs on everything from gear selection, warm-up menu, car set-up, a G-metre, race timer and engine data. The standard 'Track Pack' even includes specific circuit layouts and data.

The key differentiator between the ID.4 and ID.5 is of course the ID.5’s descending coupe roofline. I think it grants the GTX more presence on the road, and I appreciate the touch of having a true three-dimensional spoiler piece atop the boot lid to round it out rather than a more common lip or roof-mounted extension.

Outside of this, the ID.5 sets itself apart from the rest of the Volkswagen range thanks to its curves rather than hard edges as well as contemporary light bar fittings, front and rear.

The overall visage is fresh but a tad conservative, especially compared to the more radical designs we’re seeing on new-to-the-market automakers like XPeng, or those looking to make a splash with their electric offerings, like Kia with its EV5.

There’s certainly something to be said for a more moderate approach, though, as it feels more resolved than many rivals.

Inside, to a degree, the ID.5 follows similar trends in the market, with a minimalist and screen-dominated dashboard.

The 12.9-inch central touchscreen unit is less overbearing than some 15+ inch units in other cars, and this combines with the sensible 5.3-inch digital instrument cluster to make it feel more like a car than a tech product on wheels.

Still, the minimalist theme prevails, with the ID.5’s interior being free of a space-consuming raised console or a smattering of buttons to interact with.

The seats in this GTX are particularly cool, with the single-piece backing like a Golf GTI, red stitching and nice material quality. 

It leaves you with the impression the ID.5 is modern but with the build quality and know-how of a storied automaker, which is a nice balance.

At just under 4.7m long (248mm longer than the A 45 S hatch), a bit under 1.9m wide, and fraction over 1.4m tall the A 45 S in the dimensional bullseye for a compact four-door.

The CLA A 45 S driver is presented with the same sleek 'MBUX' widescreen display found in the Mercedes-Benz A-Class, and storage runs to two cupholders in the centre console, a lidded bin/armrest between the seats (including twin USB ports), decent door pockets with room for bottles and a medium-size glove box.

In a swap to the rear, sitting behind the driver's seat set to my (183cm) position, I enjoyed adequate knee and foot room, although headroom isn't as generous.

A centre fold-down armrest incorporates two cupholders, again there are generous pockets in the doors with room for bottles, and adjustable ventilation outlets are set into the back of the front centre console is a welcome inclusion. No map pockets on the racy, hard shell sports front seats, though.

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. Best for two grown-ups, and three kids will be fine.

Boot volume is a healthy 460 litres (VDA), expanding further with the 40/20/40 split-folding rear seat down. There are tie-down hooks, a 12-volt outlet and elasticised storage pockets either side of the load space to further enhance useability. But beware, the Merc-AMG CLA 45 S is a no-tow zone.

First, the less-good. The minimalist and button-free interior will be a major downside for many. Pretty much everything in the ID.5’s cabin is touch-based. There’s not even a stop/start button, you just sit in the car and it’s ready to go. Additionally, it relies on the now-maligned touch sliders below the multimedia screen for volume and temperature adjustment. Never fun to use on the move. Even the buttons on the steering wheel are the touch-based haptic-feedback kind.

At least the software shapes up. It’s easy enough to navigate, and has a slew of straightforward menus. It’s also backed by enough processing power, with swift responsiveness, and the panel quality is good too, with a sharp, high-resolution finish.

This can be a double-edged sword, though. The high-resolution leads to small shortcut icons across the top of the main screen. While I’m glad the ID.5 has these so you can swap between things like the car’s settings menu and, say, Apple CarPlay easily, it takes some accuracy to jab at while you’re trying to drive.

From there, though, the cabin is clever. Free from the trappings of buttons and a raised console, it feels spacious in every dimension and the seat comfort is excellent with lovely side bolstering and padding.

The seats feel quality, but I wonder whether the synthetic suede-style microfleece trim will age as well or be as easy to clean as cloth or leather. Worth thinking about if you plan to keep this car for a long time.

I even like the touch of having little flip-down armrests which almost makes it feel like you’re being silently propelled along in an armchair in the front seats.

You need these because there’s no traditional raised console with an armrest box. Instead there’s a flexible floating central console piece. It features a modular sort of design, where you can make use of either dividers or a drop-in bottle holder piece in either the upper or lower sections, depending on your preference. Remove these things entirely to have two massive trays.

Meanwhile, the lower section features a cubby with a wireless phone charger, and it also houses the dual USB-C ports with a sliding cover so you can keep the interior tidy. I like it.

There are large bottle holders in the doors, too, and another nice touch is the digital dash being perched on the steering column, so no matter how you adjust it, you can always see it.

The back seat is also excellent in the ID.4 and ID.5, featuring plenty of space for me behind my own driving position, at 182cm tall. There’s heaps of airspace for my knees, and because there’s a flat floor courtesy of this car’s dedicated 'MEB' platform, there’s plenty of space for your feet. It also makes the centre position usable by an adult, which is rare.

Soft trims continue in the doors, but my favourite feature of the ID.5’s rear bench is how the brand has thought to strongly contour the outer two seat backings so even they have plenty of side bolstering.

The backs of the front seats feature an upper pocket for phones and the like, and a larger lower pocket, while the doors feature a large bottle holder each. A drop-down armrest has three shaped cavities for bottles of all sizes, and behind it is a ski port door.

There are adjustable air vents and a touch panel to control the rear climate zone, but because of the low design of the central console, they’re basically on the floor. Nice to have them, but they might be hard to adjust for kids or the less mobile.

This will surprise you. The boot is bigger in the ID.5 than in the ID.4 despite this car’s descending roofline. Measuring 549 litres, it’s also good for the mid-size segment and features an under-floor storage area which is great for your charging equipment. However, there is no spare wheel, just an inflator kit, and also, the ID.5 doesn’t get a frunk like many of its electric contemporaries.

Value is an interesting thing in this case. When you compare the ID.5’s $72,990, before-on-road costs, starting price against its ID.4 Pro sibling (which starts from just $59,990) it doesn’t feel like great value.

This feeling continues when you start to line it up against recently-arrived mid-size electric Chinese offerings, like Leapmotor’s C10 (from $43,888) and Geely’s EX5 (from $40,990). 

But the ID.5 is designed to be a cut above, with a punchy all-wheel drive powertrain, and a relatively large battery, and when you consider its price against, say, the Toyota bZ4X (from $74,900 in AWD form), Subaru Solterra (from $69,990), or high-grade versions of cars a size-bracket down, like the Hyundai Kona Premium (from $68,000) or Kia Niro GT-Line (from $72,360), the ID.5 suddenly starts to look like great value.

If you want my opinion? The ID.4 Pro is still the pick of the two on raw numbers, especially since the difference in standard equipment seems to hardly justify the additional price jump, but I can see how the ID. 5 GTX can make a case for itself.

On the topic of standard equipment, the ID.5 GTX has VW’s signature ‘Matrix’ LED headlights, flush doorhandles, '3D-effect' LED tail-lights, privacy glass, an upgrade to 20-inch alloy wheels and contrasting black highlight trims with GTX highlights on the outside.

On the inside the ID.5 scores a 12.9-inch multimedia touchscreen with Apple CarPlay and Android Auto connectivity, a 5.3-inch digital instrument cluster, ambient interior lighting, tri-zone climate control, a panoramic glass roof (with powered shade), a premium Harman Kardon audio system and sports front seats trimmed in leather and 'microfleece' fabric, with power adjust, heating, and message functions for the front two positions.

On the performance front it gets the same adaptive chassis control (with frequency responsive dampers, adjustable settings and progressive steering) as the ID.4 Pro, but from there it adds a second motor (on the front axle) and all-wheel drive software with additional drive modes and an 'ESC Sport' setting.

It’s good kit, but whether it’s enough to tempt you away from its closest competitors, like the futuristic Kia EV5 GT-Line (from $71,770), incoming new Tesla Model Y (from $58,900) or unusual XPeng G6 (from $54,800) is a tough question.

The A 45 S's all-new 2.0-litre (M139) engine is claimed to be the most powerful series production turbo four ever made, pumping out 310kW at 6750rpm and a monumental 500Nm, peaking between 5000-5250rpm. . That's up from an already impressive 280kW/470Nm on the out-going model.

It's an all-alloy, closed deck design fed by a combined direct and port fuel-injection system, with a single, twin-scroll turbo featuring low-friction roller bearings for quick spool up.

It's transversely mounted, but compared to the previous model has been spun 1 80-degrees on its vertical axis so the turbo's near the firewall and the intake system sits at the front to simplify and shorten ducting on the intake and exhaust sides.

The cylinder linings are treated with Merc's patented 'Nanoslide' coating, which delivers an ultra-hard, mirror-like surface for less friction and greater durability. And 'Camtronic' variable valve control sits on the exhaust side.

Drive goes to all four wheels via an eight-speed 'AMG Speedshift DCT 8G' dual-clutch auto, with manual shift paddles attached to the steering wheel.

Instead of a frunk there’s simply a mess of hardware under the bonnet which is largely related to the ID.5’s high-voltage and cooling systems, but what sets the GTX apart is the addition of a front motor to add to the standard rear one.

It’s not a huge power boost. The ID.4 already puts out 210kW/545Nm, and the front motor on the ID.5 simply adds 40 additional kW for totals of 250kW/545Nm (as the torque figures for the two don’t simply add together).

Its claimed 0-100km/h sprint time of 5.4 seconds isn't bad, especially compared to combustion equivalents, but it’s also not as breakneck fast as some of its EV rivals.

Instead, the additional motor for the ID.5 GTX is more about adding something to the handling equation, as well as the dependability of all-wheel drive and additional drive modes. More on this shortly.

Claimed fuel economy to the combined cycle NEDC (New European Driving Cycle) standard is 8.1L/100km, the engine emitting 186g/km of CO2 in the process. Figures for the Australian (ADR 81/02) standard will be issued at the time of the car's local launch in early 2020.

Stop-start is standard, minimum fuel requirement is 98 RON premium unleaded, and you'll need 51 litres of it to fill the tank.

Our combination of furious hot-lapping on the circuit and relatively enthusiastic open road driving on the launch program means we'll wait until we test the car on home soil to log a real world average.

One of the biggest benefits of the Australian market waiting this long for VW’s ID. range is the upgraded battery and charging offering.

The ID.5 GTX has a larger battery than the ID.4, measuring 84kWh which helps off-set its slightly less efficient all-wheel drive system. The result is a WLTP driving range of 522km between charges, which is only 22km less than the ID.4. It’s still plentiful, and on the higher end at this price point.

Additionally, the charging specs are great. A peak speed of 175kW on DC means a charge time of around 22 minutes (10 - 80 per cent) on a pylon capable of outputting such a speed, while on AC it is 11kW, making it worthwhile plugging in down at the local shops.

The big missed opportunity here is the lack of vehicle-to-load, vehicle-to-grid or a household power outlet in the cabin or boot. These are convenient features becoming more prevalent in the market. At least VW throws in a wall socket and a Type 2-to-Type 2 charging cable as standard.

Mercedes-AMG invited us to the Jarama race circuit just outside Madrid in Central Spain, and the twisting B-roads nearby, to sample its latest pride and joy.

In the AMG tradition the engine is assembled by hand, by one technician. And hats off to the spanner twirlers, they do a great job. It's a spectacular unit. Torque delivery is shaped to mimic a naturally aspirated engine, with the maximum figure arriving between 5000-5250rpm.

But that's not to say it's hollow in the mid-range. Around 90 per cent of that peak number is available from below 3000rpm and low-end throttle response is brilliantly crisp and linear, helped in no small part by roller bearings on the turbo for a quicker spool up.

Merc-AMG claims 4.0 seconds for the sprint from 0-100km/h, which is supercar fast and with drive going to all four wheels entertainment is the name of the game.

The eight-speed dual-clutch auto is positive and sharp, especially in manual mode where shifts flick through in much less than the blink of an eye.

And as the A 45 S beefs up the A-Class on the outside, it's the same underneath the skin with body reinforcement including an alloy sheering plate under the engine, a front strut tower brace, extra reinforcement between side members and A-pillars, and diagonal struts on the front and rear of the underbody.

So, the strut front, four-link rear suspension has an extra stiff platform to hang from, and the three-mode 'Ride Control' active damping can transform the ride from soft and compliant to tightly buttoned down.

The speed-sensitive, electromechanical steering is specifically tuned for this car, and it points accurately with good road feel and pleasantly firm weight in Sport and Sport+ modes.

Rubber is Michelin Pilot Sport 4 S, and it grips hard. On the fast and technical Jarama circuit they performed flawlessly, helping the A 45 S transform its prodigious power into maximum forward velocity without fuss.

The icing on the dynamic cake is 'AMG Dynamic Select' with six modes from 'Comfort' to 'Race' adjusting the engine, transmission, steering, suspension, and exhaust.

On top of that 'AMG Dynamics' uses the ESP and torque vectoring (by braking) to vary the level of stability and slip through four levels from 'Basic' up to 'Master'.

We played with all the toys including 'Race Start' and a 'Drift Mode' made possible by a new rear axle featuring two multi-disc clutches - one for each rear wheel.

Torque is split variably between front and rear axles with a default setting of 50/50 rising to around 70 per cent to the rear when pushing hard. Drive is also continuously managed across the rear axle, and like a swan gliding across the lake all the action happens seamlessly out of sight, turning you into a track hero in the process.

The first-gen A45's exhaust was a mass of pops, bangs and crackles, while this car's more rasping and rorty exhaust note is controlled by a flap in the system adjusted by engine speed and load. It's also amplified by the 'AMG Real Performance Sound' system, which puts some actual engine and exhaust noise (nothing is synthesised) through the speakers.

Open road ride comfort in the softest setting is surprisingly good, with rough surfaces unsettling the car only slightly despite the big 19s and high-performance rubber. Body control is S and S+ settings is spot-on, the car feeling planted, predictable and ultra-responsive on tight, twisting backroads.

Braking power is professional grade with six-piston calipers at the front and single piston rear, on vented and perforated rotors all around. Even following session after session on the track there wasn't a hint of fade.

The ID.5 GTX isn’t quite in the same vein as other ‘performance’ EVs. It feels more measured than a Tesla Model Y Performance for example. But then it also feels a lot more organic. It feels a lot more like a car.

This is because rather than focus on straight-line performance, the GTX has benefits when it comes to its handling. Compared to the ID.4, for example, the ID.5 is sharper on its front axle, adding a little additional torque at the front to make it sharper and faster to grab the tarmac.

Its accelerator response may be comparatively steady, but somehow the ID.5’s more traditional stability control tuning allows it to have a bit more leeway when you push it in the corners. It grants it a little extra fun factor, where some rivals are too locked down.

Additionally, VW’s experience in providing a balanced ride and sharp steering tune is on full show. While a lot of electric vehicles in this class feel a little over-electrically assisted or even vague when it comes to the steering, the ID.5 feels connected and accurate.

The adjustable ride settings are also a rare win for an electric mid-sizer. This is because you can adjust the ride to suit the conditions. If you’re on a bumpy suburban road for example, you can keep it nice and soft. But if you’re out carving corners in the countryside, a much firmer setting is available to help limit the amount of floaty rebound this car’s low-set battery weight can have.

It does adjust in a limited band, so there’s still a bit of softness to it, which combines with the predominantly rear-drive characteristics to make for a distinctly different vehicle to a Tiguan, for example.

It’s simply not as athletic as VW’s finely-tuned combustion offerings, but then its more plush open-road feel isn’t necessarily worse. At the very least it maintains all those key refinement characteristics which make Volkswagens generally a cut above to drive.

Another key aspect of the driving experience these days is how much active safety equipment wants to interfere with the experience. Many newer automakers struggle with calibrating for Australian conditions, and yet, like many European automakers, Volkswagen has nailed it with the tuning of these systems in the ID.4 and ID.5.

I wasn’t annoyed by any system, even repeat offenders like lane keep assist or driver attention monitoring in our whole two-day drive, which speaks volumes about the difference between the ID.5 and something like a Leapmotor C10.

The ID.5 comes equipped with the full array of active safety gear as standard, with autobahn-speed auto emergency braking, lane keep assist, blind-spot monitoring, rear auto braking, rear cross-traffic alert and adaptive cruise control.

It is also equipped with seven airbags (including the more recently-introduced front centre airbag) and wears a maximum five-star ANCAP safety rating... for NZ-delivered variants. Australia will surely follow soon, but at the time of writing the ID.5 is not ANCAP rated for this side of the Tasman.

The Mercedes-AMG range is covered by a three year/unlimited km warranty, which, like Audi and BMW lags 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 assistance is included in the deal for three years.

Service is likely to be scheduled (as per the out-going CLA 45) for 12 months/20,000km (whichever comes first) with pricing available on an 'Up-front' or 'Pay-as-you-go' basis.

For the first-gen CLA 45 pre-payment delivers a $500 saving with the first three services set at a total of $2950, compared to $3650 PAYG. Fourth and fifth services are also available for pre-purchase.

VW hasn’t used this opportunity to increase its standard warranty terms of five years and unlimited kilometres, however, the battery pack is covered by an industry standard eight-year/160,000km deal. 

There are other ownership perks designed to coax people into an electric car, though. Servicing, for example, is only required once every 24 months or 30,000km and when packaged up at the time of purchase, very affordable.

A 10 year or 150,000km plan costs $2890, or just $289 a year, which is excellent for a European car, and is even more affordable than some of its Korean and Chinese rivals with generally longer service intervals.

On top of this, VW stresses the repairability of its battery components, and promises parts supply will continue for 10 years after the discontinuation of the ID.4 and ID.5 range in its current form, with repairability through its network for at least 15 years.
