Mercedes-Benz A45 vs Lexus CT

What's the difference?

The Mercedes-AMG A 45 4Matic+ may have grown up a bit in that it’s not as noisy or uncomfortable as the first-generation version which arrived in 2013, But if anything, its more portent than ever. Superb Mercedes-AMG craftmanship, outstanding performance and good value as far as bang for your buck goes.

The cheapest Lexus of them all isn’t chasing badge snobs with the CT200h as blatantly as Mercedes-Benz, BMW and Audi do with their entry level cars… but it’s perhaps not quite the Lexus you’d expect it to be.

It has a lovely front-of-cabin, for example, but there’s a lot of last-gen Prius in plain sight in the rear of the cabin.

The hybrid powertrain, too, is noble in concept, but the day-to-day reality is that it’s not as nice to drive, especially town to town, as a regular petrol-powered car of similar size.

The foot brake, silly multimedia joystick and odd gearshifter also spoilt the party a bit.

Empty nesters who are looking for a nice city runaround with a tinge of greenwash about it will love it… and if the current Prius is anything to go by, the next CT will be a very good thing indeed.

When I went to pick up the Mercedes-AMG A 45 S 4Matic+ I walked right past it and then like that lost and confused John Travolta in Pulp Fiction internet memes, wandered around before asking where the car was.

That’s because I was looking for something with a gigantic spoiler on the roof and probably hi-vis green with stripes. But the car assigned to me was the A 45 S in its standard form, and the styling is subtle enough for it disappear into a crowded car park like James Bond into a lavish dinner party.

But like Bond, chances are the A 45 S is the most hardcore person in the room, it just doesn’t walk in announcing it to everybody.

Look closely and you'll see that the A 45 S is not just another small prestige car. There’s the 90mm quad exhaust poking out of the chunky diffuser, the giant 'Panamericana' grille, and the angry looking front apron.

Then, there are the 19-inch matt black alloy wheels wrapped in low-profile Michelin rubber and enormous brake discs with their red calipers, all barely contained by the pumped up front wheel guards which are much bigger than those on a regular A-Class.

The cost option my test car wore was the 'Mountain Grey Metallic' paint, but if anything it made the A 45 look even more covert.

The cabin is small but luxurious and sporty with two-tone leather upholstery (the red and black 'Lugano' leather in my test car is a no-cost option), there’s the microfibre-clad AMG steering wheel, brushed aluminium trim, metal-trimmed pedals and the large display panel (it’s actually two screens joined) is also standard.

The A 45 S is a hatchback measuring 4445mm in length, 1850mm wide and 1412mm tall. Not keen on a hatch but want something with similar dimensions? The CLA 45 S is the A 45 S’s four-door twin-under-the-skin and is just as much of a weapon.

And if you want your A 45 S to look more aggressive, you can option the 'AMG Aero Package' which will see a giant rear wing fitted to the roof.

Or you can buy the Edition 1 version of the A 45 S which includes the big spoiler and shouty design bits to makes sure everybody knows you’re the assassin in the room.

There are some light external revisions for the latest update of the compact Lexus CT200h. New grey 17-inch alloys are unique to the Sport Luxury, along with a black roof treatment, new L-shaped LED driving lamps that match new-design LED tail-lamps, while Lexus designers have also added its new spindle grille to the brand’s smallest model.

It manages to be inoffensive, but it doesn't really reflect the brand's latest design language of 'real world concept cars' like the NX and the LC ranges.

Inside, a couple of new leather colour options are available for the CT200h, while the addition of the wide-format 10.3-inch screen to the top of the centre console is the single largest change. Interestingly, the steering wheel controls appear to have regressed a little from the previous model, no doubt brought about by the addition of the new driver aids.

Along with good performance and handling, part of the appeal of hot hatches is that they’re practical… to a degree. The A 45 S is a small car, but it has four doors, five seats and a boot.

The cabin is small, no doubt about it, but even at 191cm tall I had plenty of room while driving, the seating position is perfect actually, although sitting behind my driving position saw my knees just touching the seat back.

Headroom is getting limited back there, but I still had space. Could you get away with the A 45 S as a family car? I had my family in it for a while, but there’s just the three of us and my son is pre-school-aged. So, a young, small family, yes… until it starts to grow.

Cabin storage is good with two cupholders in the rear centre fold-down armrest along with small door pockets and seat-back nets. Up front there are another two cupholders, giant door pockets, a big split-opening centre console bin and a tray for the wireless charger big enough to fit an iPhone 11 Pro Max.   

Boot space is good at 370 litres. The big shiny CarsGuide suitcase fitted in easily (see images) and apart from the wide-opening of the boot, another hatch power of practicality is that you can fold the rear seats down to open up more cargo carrying space, and in the A 45 S’s case that’s 1210 litres.

I’ve mentioned the wireless charger but there are also four USB-C ports (two up front and two in the rear), back seat passengers also have directional air vents, which is another bonus, along with dark tinted windows (welcome when my son was sitting back there in his car seat).

The CT200h basically replicates a small hatchback in terms of interior size. It'll seat five, but if you try to put three adults across the back, they won't be particularly happy about it. 

The roofline is quite low and the car’s waistline is high, which makes the glasshouse feel small. Room in the front is adequate, but only just for taller drivers; the sunroof, as fitted to our test example, takes away a good chunk of headroom, despite the CT200h standing just 5mm lower than a Corolla overall. 

The seats themselves, too, are mounted just a touch high to be comfortable for taller drivers, while rear seaters will complain bitterly about being stuck behind my (184cm) driving position. However, my more diminutive wife pronounced herself very comfortable behind the wheel and in the passenger seat.

A nice, small steering wheel sits in front of a single-dial dash that sports two digital screens either side. The left-hand screen changes when you change the drive mode dial between Eco, Normal, and Sport. And there's also a full EV mode button in handy reach. 

Two cupholders are line astern between driver and passenger, although storage is at a premium thanks to the size of the car. Climate and multimedia controls - and even an old-school CD player – flow right through underneath the centre console, which steals away valuable space. There are no extras like wireless charging bays, nor is there Apple CarPlay or Android Auto.

There are bottle holders in the door, but don't try and stash anything that's over one litre in size because it just won't fit.

It's quite an austere proposition for rear-seat passengers, with no bottle holders in the doors, no cup-holders and no charging points. There are fixed vents under the front seats and on the right side of the rear area, so it's not a complete desert, and there are ISOFIX mounts for two child seats in the rear.

Another practicality issue that's unique to the CT200h is the gear shifter. It operates as a spring-loaded joystick, and unless you're watching the dash indicator, it can be tricky to know which gear you're in. Other car makers have actually recalled cars with this style of transmission stick, and it's certainly something that you have to get used to. 

Likewise, the old-school foot brake is certainly an anachronism in something like a Lexus.

Based on the previous generation Prius, the nickel-metal hydride battery for the CT is hidden underneath the rear seat, so it doesn't steal away too much boot room. However, the boot floor is still quite high, and the area is rather small at 375 litres with the seats up. There is 985 litres available when you drop the seats, but the aperture is short and narrow, so larger items will be a squeeze. There is a space-saver spare nestled away underneath the boot floor, too.

Another practicality note in the negative column is Lexus's insistence on the odd joystick control for its multimedia system. It's simply not very good. It’s imprecise when compared to a touchscreen, the action and feel of our test unit was very much less than premium, and it’s just awkward and clumsy to use. The CT is not the only Lexus to use it, but we wish the company would just see the light and ditch it all together.

The 1.8-litre petrol-electric CT200h comes in three different flavours – the Luxury, the F-Sport as tested here, and the Sport Luxury. The range now kicks off at $40,900 (up $2150) and peaks at $56,900 with the Sport Luxury (up $810).

The F-Sport may be a little lacking in the actual ‘sport’ department, but it’s is pretty flush with flash kit, including not one but three motors (one petrol and two electric), auto lights and wipers, a wide 10.3-inch multimedia system, leather seats, dual-zone climate control and new 17-inch alloys.

At $50,400 plus on-roads, the F-Sport has jumped in price by $1960, but it’s gained a host of new gear, including a new driver aid system that adds auto emergency braking (AEB), pedestrian-detecting pre-collision warning system, lane departure warning with steering assistance and adaptive cruise control.

There are also LED headlights and taillights, as well as revised styling for the front and rear bumpers.

The CT will be cross-shopped against other premium tiddlers like the Mercedes-Benz A-Class, Audi’s A3 and the BMW 1 series. Comparing it like-for-like in the hybrid category, there’s the top spec Toyota Prius i-Tech, while Nissan’s Leaf could theoretically be lumped in both on price and on environmental grounds.

There may be hot hatches out there which look wilder than the Mercedes-AMG A 45 S 4Matic+ but do they have the most powerful four-cylinder engine ever to go into a mass-produced car? Nope, but the A45 does: it’s a 310kW/500Nm turbo-petrol four.

It doesn’t sound as angry and gravelly as the previous A 45’s engine but it has more grunt (an extra 30kW/25Nm) and is claimed to catapult the hatch from 0-100km/h in 3.9 seconds.

The '4Matic' part of the name indicates the hatch is all-wheel drive and the '+' means it’s a more sophisticated version of the system which allows all of the drive to be sent to one axle, if need be.

What need would that be? The need to drift, of course, which should be up there with other human rights such as clean air, fresh water and free speech.

Yep, the A 45 S comes with 'Drift Mode' (for the racetrack, of course), along with a 'Launch Mode' for perfect-every-time transitions to warp speed.

Changing gears gunslinger-fast is an eight-speed dual-clutch automatic transmission.

The 1.8-litre twin-cam petrol engine makes a relatively low 73kW and 142Nm, while a 60kW, 207Nm electric motor that’s also connected to the front wheels chips in its share.

Combined, the system produces 100kW, while the torque figure translates to around the 150Nm mark. That juicy 207Nm doesn’t come into play, sadly, given that the petrol engine – which is built to run cooler than a traditional Otto cycle engine, and therefore more efficiently – does most of the work.

Throw in a transaxle for the electric motor and a power inverter, and things are getting complex. However, if the Prius is any indication, the CT200h’s drivetrain is durable and relatively serviceable, with batteries estimated to last ten years or longer.

Mercedes-AMG says the 2.0-litre, turbo-petrol, four-cylinder in the A 45 S should use 8.9L/100km after a combination of open and urban driving.

My fuel test saw me drive 131km of urban and country roads, plus some motorway sections, and needed 16.9L of premium unleaded petrol to fill the 51-litre tank back to full.

That comes to 12.9L/100km, which is thirsty, but my driving style may have contributed significantly to that high figure.

Here’s the odd thing – over 220km of largely highway driving, I couldn’t get the CT200h under a dash-indicated 10.4 litres/100km, against a claimed combined fuel economy figure of 4.4L/100km. 

I topped the tank off with 18 litres of fuel, which works out at a closer 8.8L/100km… but it still ain’t anything like 4.4. 

Another owner I spoke to, though, said he regularly records high fives with his CT200h in mixed conditions.

It runs a 45-litre tank that’ll happily take 95 RON fuel.

I wasn’t lying in the introduction to this review. The previous A45 was a pretty intense driving experience. The ride felt brutal, the exhaust note screamed and crackled like somebody had set a wheelie bin full of fireworks alight.

And then there was the sweating. I seemed to sweat a lot driving it and there was nothing wrong with the climate control, that just happens to me when I’m under pressure and excited.

So, has the new-generation A 45 S 4Matic+ gone all soft and quiet on us? No, but things have been toned down a tad.

The exhaust note is not as gruff or loud, and even in 'Sport +' and 'Race' mode it’s still quiet enough to pull into a driveway at night without making enemies of your neighbours.

And the ride is also not as harsh, although even in 'Comfort' mode my wife still found it verging on too firm.

The performance and dynamics, however, felt as sharp as ever.

Acceleration is supercar quick at 3.9 seconds. My gawd, you needed a Ferrari F40 to do that in the mid-’80s, and even now the new Mercedes-AMG GT S supercar gets there only a tenth of a second earlier, and it has a twin-turbo V8.

Top speed for the A 45 S is electronically limited to 270km/h. But hot hatches aren’t really about straight-line speed, they’re more about bent-line speed. You know, corners.

So, I took the A 45 S on the twisty roads I take anything that calls itself sporty. The agility of the A 45 S is outstanding thanks to a rigid chassis that handles a change in direction as quickly and easily as you can turn your head.

The brakes bite hard when they have to, and the all-wheel drive hatch scrambles tenaciously out of corners.

A racetrack is really the best place to truly test a serious sports car's limits and our own James Cleary did just that when he drove the A 45 S at its international launch.

As a daily driver, though, for somebody who occasionally likes to get into it on a curvy road the A 45 S is comfortable enough to live with, but hard enough to remain engaging and dynamic when you get the chance to have a squirt.

If you've ever driven a Prius, then you'll be very familiar with the way that the CT drives. Based around a 73kW Atkinson cycle petrol engine which focuses on fuel efficiency rather than outright power, a 60kW electric motor (the pair combine to produce 100kW in total), a nickel-metal hydride battery array and a CVT gearbox, the CT200h – like the Prius – is a bit different to a regular hatch.

Under light throttle, the CT is quiet and moves along quite well, and you can even use full Electric Vehicle mode at speeds under 45km/h for a brief amount of time, (slightly less than two kilometres), and with a very gentle right foot.

The battery array is recharged via the petrol motor as well as regenerative braking (where heat energy is captured and directed back to the electric system) – but unlike a petrol-electric plug-in hybrid, there’s no way to stick a 240v cable into the CT to top up the battery. 

It has the unusual whines and odd noises that you would associate with a partly electric car, but the petrol motor sounds just like a regular old four-pot petrol unit, and it’s running most of the time.

One issue with the drive of a hybrid is its ability, or the lack thereof, to get off the line in any sort of hurry. You really have to mash the throttle to get going, which takes some getting used to. There’s also some hesitation and un-Lexus like thumps from the drivetrain if you confuse it by almost stopping then taking off again.

The CT200h’s biggest bugbear is that the fourth generation Prius exists. Built on a more sophisticated newer-generation platform and with a more refined drivetrain, the new Prius is a great insight into how good the next CT will be – and what the shortcomings of the current one currently are.  

The CT works well in high-traffic city environs, where a light throttle foot helps get the best out of the unusual drivetrain. Lots of lag from rest is an annoyance, as is an excess of CVT whine under hard efforts, but the CT200h pootles around town very well.  

Its small size does play against it when it comes to keeping out road noise at freeway speeds, though the CT is superior to most other similarly sized cars in this regard. As an aside, its build quality is nothing short of amazing, with minimalist panel gaps, a tight interior and lashings of paint on every surface.

Part of the update for 2018 is the addition of several driver aid systems, including AEB across the range, lane departure control with steering and adaptive cruise control. 

The F-Sport also has reversing camera and eight airbags as standard, ensuring the maximum five-star ANCAP safety score it managed in 2017.

The Mercedes-AMG A 45 S 4Matic+ is covered by a five-year/unlimited kilometre warranty.

Servicing is recommended at 12 month/20,000km intervals. Servicing is capped at $850 for the first year’s visit, $1200 for the next and $1600 for the third.

Lexus sells the CT with an unusual four-year/100,000km warranty, which includes roadside service coverage. The battery pack has an eight-year/160,000km warranty, while Lexus would like to see you back for a service every 12,500km or 12 months.
 
It’s not just about a warranty or a service interval with Lexus, though. For decades now, its customer service record has topped all industry measures, and everyone we know who has bought a Lexus with their own money has raved about the quality of the service received. 

As well, it’s a level of service that’s provided across the range. It’s a tangible benefit of buying a CT200h.
