Lexus IS200T vs Mercedes-Benz CLA250

What's the difference?

The Lexus range comes with a four year/100,000km warranty with roadside assist for the duration. Servicing is every 15,000km or twelve months, whichever comes first.

Sadly, there's no fixed or capped-price servicing regime, not even a pre-pay option like the stingy Germans. Lexus will only commit to indicative pricing, although the first service at 15,000km is priced keenly - it's free.

When you buy a Lexus, they don't like to let go of you. My father-in-law's original IS 200 is still fetched by the dealership - should he so desire - for its annual service. If he chooses to darken the dealership door himself, he'll drive out in a loan car. Nobody has ever stalked him at the dealership demanding he consider a new one.

The IS200t seems the pick of the IS bunch, despite pricing on par with a couple of the IS350s. It's a worthy alternative to the usual suspects, with its own look, feel and approach to luxury motoring. In fact, it's far more a luxury car than sports sedan, but manages to do both well. In the end, a BMW will edge it for handling and overall chassis grace, the Merc has that badge and the Audi is all-wheel drive and bang-up-to-date.

But none of them can touch the Lexus for after-sales service nor are any of them quite as well put together as the Japanese-built IS. It may not be as fast or as fun, but it's very, very good.

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.

The current IS is by far the most distinctive of the three generations. With a couple of exceptions, it is a terrific looking car. It looks long and low slung, like the best sporting sedans, with an almost Maserati-like approach to its proportions. The loud and proud Lexus spindle grille - the object of such derision when it first arrived - looks utterly fantastic and draws attention away from the odd, squished headlights.

it is one of most comfortable cars you can buy, for both front and (short) rear seat passengers.

Inside is less impressive, with a weird stacked dash and integrated screen. The materials are top notch, however and while the designers have tried to do something interesting with the dash design, there are better ideas out there they might want to consider next time around.

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 IS's cabin is probably the weakest point of the car, with limited storage for your bits and bobs. Front and rear seat passengers do get cupholders for a total of four, but the rear doors don't have bottle holders, limiting you to the two upfront.

On hot days like Sydney's 2017 summer, those cooled seats are heaven-sent.

The centre console bin is small and is the only place for your phone apart from the cupholders, which isn't an ideal spot, let's face it. The boot is a German-matching 480 litres and you can split fold the seats for more room.

Having said that, it is one of most comfortable cars you can buy, for both front and (short) rear seat passengers. The front seats are especially good and on hot days like Sydney's 2017 summer, those cooled seats are heaven-sent.

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.

The new CLA 45 is launching in the premium S variant only (a 'base' non-S version is offered in other markets). The outgoing model was tagged at $93,800, before on-road costs, prior to its discontinuation in January this year, and Mercedes-Benz Australia has hinted strongly that a price increase is likely. So, expect a list price in the mid-$90k range.

We'll cover active and passive safety tech in the safety section, and although final Australian specification is yet to be confirmed you can expect the stand ard features list to include the 19-inch alloys, 'Artico' faux leather and 'Dinamica' microfibre trim upholstery, the 'MBUX' widescreen cockpit display (two 10.25-inch digital screens) and 'MercedesMe' voice recognition, heated and electrically-adjustable sports front seats, auto adaptive LED headlights, LED tail-lights and DRLs, keyless entry and start, auto-dimming rear-view mirror, dual-zone climate-control, sat-nav, multi-function sports steering wheel, active cruise control, rain-sensing wipers, Active Parking Assist' (with ultrasonic proximity sensors front and rear), rear privacy glass, plus premium audio with digital radio, as well as Apple CarPlay and Android Auto.

The 200t denotes a 2.0-litre turbocharged four-cylinder under that long bonnet, delivering 180kW and 350Nm to the rear wheels via an eight-speed automatic transmission. This translates to seven seconds dead to 100km/h for the 1680kg sedan, which isn't hanging around.

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.

Try as we might - and we did - we couldn't get at all close to the claimed combined fuel figure of 7.5L/100km. We didn't even hit the standard plus 30%, but we did get 12.2L/100km. That's a fairly solid miss.

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.

After having the good fortune to step out of the IS350 and into the 200t, it was immediately apparent that the 200 is the better car. For a start, it feels so much more nimble. Sure, it doesn't have the seamless urge of that silky V6, but the 2.0 turbo does a fine impression of a bigger engine. Once on boost, the engine is smooth with a lovely flat torque curve. If you're off boost, though, you're in a bit of trouble - the eight-speed is reluctant to downshift and needed prodding from the steering wheel mounted paddles on occasion.

As with just about every Lexus, the ride is impeccable and refinement virtually unmatched in the class.

From a driving point of view, the fundamentals are better - less weight over the front wheels meaning the steering feels better, it turns in better and it moves more fluidly, which is impressive because the 350 isn't a slouch. Even the dashboard is better. The 350 has a traditional two clock arrangement where the 200t has a single dial in the middle that is digitally remastered. Press a button and it slides to the side to provide extra info on your choice of the available data. It leaves a fair amount of black space but it's easier to read and doesn't suffer as badly from reflections.

As with just about every Lexus, the ride is impeccable and refinement virtually unmatched in the class. There's something about the way a Lexus knocks the edge of all but the biggest bumps, sails over speed bumps and handles imperfections that is hard to beat and hard to find unless you're spending really big bucks. The adaptive damping never feels like it's doing anything which is exactly the point - even when switching to Sport+, there's an ease to the ride without it feeling loose.

You'll barely know the engine is there, and the way the transmission slurs around the gears means non-stop serenity.

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.

Although final Australian spec is yet to be finalised, you can expect a host of active safety tech including ABS, BA, EBD, stability and traction controls, a reversing camera (with dynamic guidelines), 'Active Brake Assist' (Merc-speak fo AEB), 'Adaptive Brake', 'Attention Assist', 'Blind Spot Assist', 'Cross-wind Assist', 'Lane Keep Assist', a tyre pressure warning system, the 'Pre-Safe' accident anticipatory system, 'Traffic Sign Assist' and 'Adaptive Highbeam Assist'.

If all that fails to prevent an impact you'll be protected by 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. A first-aid kit and hi-vis vests in the boot are thoughtful additions.

The A-Class 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.

The Lexus range comes with a four year/100,000km warranty with roadside assist for the duration. Servicing is every 15,000km or twelve months, whichever comes first.

Sadly, there's no fixed or capped-price servicing regime, not even a pre-pay option like the stingy Germans. Lexus will only commit to indicative pricing, although the first service at 15,000km is priced keenly - it's free.

If he chooses to darken the dealership door himself, he'll drive out in a loan car. Nobody has ever stalked him at the dealership demanding he consider a new one.

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.
