Mercedes-Benz E-Class vs Infiniti Q60

What's the difference?

The Mercedes-AMG E53 Hybrid 4Matic+ is a superb blend of high-tech hybrid muscle and cossetting top-end luxury. Value is competitive, it looks (and feels) the business, despite the conventional sedan configuration it’s surprisingly practical (except for the modest boot), fuel-efficiency is a key benefit and safety is stellar. The ownership proposition is okay for the category but that’s not top of mind when an enticing series of corners ranges into view. It’s an impressive package.

Beautiful looks, good handling, but the driving experience of the Q60 GT is let down by a numbness and disconnection relative to what's happening under you. Refinement isn't on the same level as its BMW and Benz rivals, but the GT is a perfect match for the RC 200t, while remaining good value for money. If you have your heart set on an Infiniti Q60 then I'd skip straight to the top and opt for the Red Sport.

At first glance the E53 passes as a flash-looking Mercedes-Benz E-Class running 20-inch rims, especially in the launch car’s rich ‘Patagonia Red’ finish.

But then, there’s something about the AMG sedan’s stance that sets it apart. Which makes sense because the front fenders are wider by 11mm on both sides (compared to the E-Class) to make room for a wider front track (increased by just over 30mm over the previous-generation E53).

Wheelbase has also increased by just over 20mm to almost 3.0m and the car’s more aggressive nose treatment enhances the distinctive look.

There’s the AMG-specific radiator trim with ‘Panamericana’-style vertical slats, the sleek dual-section headlights and a large lower inlet that directs air to an additional front intercooler as well as an external opening for a wheel-arch cooler.

In profile there’s barely a hard edge to be seen, although character lines in the bonnet and along the car’s flanks contribute to a taut surface treatment.

At the rear, horizontally-connected LED tail-lights feature a stylised Mercedes three-pointed star signature, then a rear apron housing a diffuser and twin double tailpipe ‘trims’ and a bootlid spoiler on the left and right round off a beautifully proportioned design.

Climbing inside means a trip to screen city with an upright digital display in front of the driver flanked by a large central screen to the left and an additional panel for the front passenger beyond that. It’s a lot.

But once you’re on top of all the glass surfaces, details like open pore grey ashwood trim on the lower console come into focus, as do the brushed metal accents, beautifully sculpted ‘Performance’ front sports seats (optionally fitted to our launch drive example), racy stainless steel pedal covers and the five spoke AMG performance steering wheel with configurable rotary buttons.

It’s a supremely luxurious and comfortable interior. 

The Q60 GT is a head turner – literally. Whenever I was driving slow enough to notice, people were rubbernecking to look at the long, low-slung coupe. I'm sure most had no idea what brand of car it was, but in its 'Iridium Blue' paint the Q60 looked amazing with its curvy, sleek profile.

There's only one small issue – the RC 200t and Q60 GT are way too similar looking, right down to their 'signature' shaped c-pillars. I prefer the grille of the Lexus but the rear of the Q60. While there might be a bit of copy-catting going on, both are prettier than their BMW or Benz rivals.

The Q60 GT feels fairly large to drive and the dimensions don't lie – 4690mm end-to-end, 2052mm across with the wing mirrors unfurled, but low at 1395mm.

The cabin treatment is just as emotional as the exterior, with its dual screens, swoopy dashboard and sectioned off driver and passenger cells.

At over 4.9m long, close to 2.1m wide and a little under 1.5m tall, with a 2961mm wheelbase, the new E53 is a substantial car and feels it on the inside.

Plenty of breathing space for the driver and front passenger thanks in part to the away slope of the screen-dominated dash.

Generous storage, too, with large door bins including enough space for big bottles, a deep lidded box between the seats (which doubles as a centre armrest), a generous glove box and two cupholders under a sliding top at the front of the centre console. 

Hit the second row, and sitting behind the driver’s seat, set for my 183cm position, I have plenty of head and legroom, with enough shoulder space for three adults on short journeys. A trio of up to mid-teenage kids will be fine for a road trip.

Storage is pretty handy as well with hefty door bins and two pop-out cupholders in the fold-down centre armrest. No map pockets on the back of the (optional) Performance front seats, though.

Four-zone climate control means there’s individual temperature control for each side of the back seat, with adjustable vents at the back of the front centre console and trailing edge of the B-pillars. Very civilised.

Power and connectivity runs to three USB-C outlets and a wireless device charging pad in the front.

Thanks to the traction battery under its floor, boot volume is restricted to 370 litres (compared to 540L in the conventional E-Class sedan), although there are bag hooks, tie-down anchors and the 60/40 split-folding rear seat is able to liberate more space.

No spare tyre of any description, just a repair/inflator kit, which might make sense for automotive designers and engineers trying to maximise space and reduce weight, but doesn’t make sense for an owner stranded on the side of the road with an unrepairable puncture.

The short answer is not very practical - but then no two-door sports car really is. So while the front two seats are roomy (although the optional sunroof restricts headroom) the same can't be said for the back seats – at 191cm tall, not only can I not sit up straight (because of the sloping roofline), I can't fit my legs in behind my driving position.

While those large doors open wide the roofline and the lack of rear doors means trying to insert a toddler into his car seat was painful and involved kneeling in the street, there were days we took our much less fancy SUV just because it was easier.

This is a four seater – with two cupholders in between the rear seats and two more cupholders up front. Storage elsewhere is limited, with tiny pockets in the front doors and a small centre console bin to hide your phone and wallet.

The boot is also on the small side at 341 litres – don't compare this to the 423 litre of cargo capacity in the RC 200t which is measured in VDA litres. That said, there was more than enough room for our weekly shop which fitted in snugly, although you have to hoist your shopping bags high to clear that boot lip.

The Q60 GT has a list price of $62,900, undercutting the Lexus RC 200t by $2000, but what you might find surprising is that the Benz C200 Coupe is only $3500 more than the Infiniti, while the BMW 420i in the Luxury grade lists for $69,900. Depending on how you look at it, either the Germans are affordable or the Japanese are expensive. Perhaps a bit of both.

It's not bad value for money, but it would be good to see other features such as Apple CarPlay and Android Auto added.

What's for sure is that the Q60 GT's standard features list is substantial. There's 8.0-inch and 7.0-inch 'double-decker' screens, sat nav, reversing camera, front and rear parking sensors, six-speaker stereo, LED head- and fog lights, proximity unlocking, heated and power adjustable front seats and leather upholstery.

It's not bad value for money, but it would be good to see other features such as Apple CarPlay and Android Auto added along with adaptive cruise control.

The Q60 Sport Premium is the next grade up from the GT and lists for $70,900, while the Red Sport is $88,900.

The E53 is powered by a 3.0-litre, turbo-petrol, in-line six-cylinder engine working in concert with an electric motor housed within the car’s nine-speed (torque-converter) automatic transmission. 

Drive goes to all four wheels via an electro-mechanically controlled clutch distributing power between the front and rear axles.

Engine performance is up by around 10kW compared to the previous E53 thanks to software upgrades, a new twin-scroll turbo with higher boost pressure (1.5 bar vs 1.1 bar) as well as additional front and wheel-arch intercoolers. 

The engine alone produces 330kW/560Nm while the permanently excited synchronous motor chips in with a solid 120kW/480Nm for overall outputs of 450kW/750Nm.

The Q60 GT has a 155kW/350Nm 2.0-litre four-cylinder turbo-petrol engine with drive being sent to the rear wheels through a seven-speed automatic transmission. The same engine is also in the Q60 Sport Premium, while the Red Sport packs a twin-turbo V6.

The E53’s official combined cycle (urban/extra-urban) fuel figure is 1.7L/100km, a spectacularly frugal number for such a high-performance machine. But it’s worth noting it’s predicated on the drive battery being constantly and completely recharged.

Speaking of which, the 28.6kWh, 400-volt traction battery is housed at the rear of the car under the boot floor. It delivers a claimed EV-only range of up to 100km, although that will diminish dramatically if you decide to push up towards the car’s pure-electric top speed of 140km/h.

Important to note the battery’s 21kWh ‘day-to-day’ capacity, designed to keep charge in reserve for any required ‘high-performance boosts’.

An 11kW AC charger is onboard with regenerative braking also harvesting energy, the car automatically selecting the level of recuperation power in line with traffic conditions.

In pure EV mode you can also manually adjust regen through four levels via the steering wheel-mounted transmission shift paddles. 

Auto stop/start for the engine is standard and 98 RON premium unleaded is recommended, although 95 RON is okay at a pinch.

The E53’s official fuel consumption figure and 50-litre tank capacity translate to a range approaching 3000km! But to bring that down to earth somewhat, on the launch drive program, covering urban and mostly highway running, we saw a (dash indicated) average of 6.4L/100km, which equates to a more realistic, but still lengthy, 780km between fills.

An official combined fuel consumption figure of 7.7L/100km is fairly optimistic and our combination of urban, city and highway running saw the trip computer reporting back to us with 9.1L/100km. Still, that's not too bad considering how much time was spent in city traffic.

If you’re lining up for a Mercedes-AMG you want an optimal blend of luxury and performance and the E53 Hybrid 4Matic+ nails that delicate balance.

With 450kW (that’s 612hp!) and 750Nm under your right foot, engaging ‘Race Start’, pushing the accelerator to the floor and letting the car do its thing will result in 0-100km/h acceleration in 3.8 seconds. The fat band of mid-range torque is so satisfying to lean into.

Induction, engine and exhaust sounds combine to produce a suitably gruff soundtrack with the hybrid powertrain operating seamlessly. Hit your preferred track day or tempt legal fate and you can explore the car’s claimed (governed) maximum velocity of 280km/h. 

The nine-speed auto is slick and manual changes using the wheel mounted paddles are rapid.  In normal conditions the AWD system is biased to the rear and an electric rear locking diff helps keep things under control if you decide to get the bit between your teeth on a twisting drive.

A chunky brace links the front suspension strut mounts and the car feels predictable and stable in enthusiastic cornering. Rubber is Michelin Pilot Sport 4S (245/35 fr / 275/30 rr) which grips with satisfying determination but does make its rumbling presence felt on anything approaching a coarse chip surface (despite the car’s standard acoustic glass).

Speed-sensitive power-steering delivers accuracy and good road feel without any jitters, the standard active rear-axle steering playing its part. The ‘turning point’ is 100km/h with the rear wheels subtly turning in the opposite direction to the fronts up to that speed and in the same direction beyond it.

‘AMG Ride Control’ combines steel spring suspension (strut front, multi-link rear) with adaptive adjustable damping for the choice of ‘Comfort’, ‘Sport’ and ‘Sport+’ settings. Comfort is the pick for B-road running on typically uneven surfaces. The optional ‘Performance’ sports front seats are comfortable and grippy in equal measure. 

Braking is by ventilated composite rotors all around, with beefy four-piston fixed calipers up front. An electro-mechanical brake booster is designed to combine electrical recuperation with the hydraulic brake for more frequent and efficient energy harvesting over a longer period of time. The pedal feels firm and progressive with smooth initial bite. 

All around vision is good for a conventional sedan with a quality reversing camera, 360-degree overhead view and front and rear parking sensors helping massively with parking duties. That said, a 12.5m turning circle isn’t tiny.

I had a feeling this would happen - the GT was disappointing to drive after the Red Sport with the latter's twin-turbo V6, sports suspension, better steering and excellent Sport + drive mode. There's lots to like about the GT, though – the grip is great from the wide Dunlop SP rubber (235 40 R19 front and 255 40 R19 rear), the chassis feels taught, acceleration is good and it's a gorgeous looking car.

But there's a sense of disconnection from the driving experience I couldn't get past, such as the numb feeling in the steering which needed constant re-adjustment. I also think the suspension felt over sprung and lacked composure over small bumps in the road.

The GT and all Q60s don't have the same level of refinement as the C200 Coupe or 420i, evident from the clunky feel of the door handles to the road noise intruding into the cabin.

That 2.0-litre engine is great, but the transmission is a mood killer with it wanting to change up gears quickly to save fuel.

I'm not a fan of the cockpit. Sure it's brave and expressively designed, but the double-deck screens are confusing, there's one for nav, while the other's for media... I think. Then there are things you don't need, such as a digital compass – actually there are two, one on the display and another in the instrument cluster, but there's no digital speedo.

That 2.0-litre engine is great, but the transmission is a mood killer with it wanting to change up gears quickly to save fuel, even in 'Sport' mode.

Here's a curve ball call for you – I've just stepped out of a, Alfa Giulia Super. Close in price to the Infiniti, same sized engine, but infinitely more rewarding and fun to drive – plus you get an extra two doors.

The Q60 is yet to be rated by ANCAP, although it's good to see AEB with pedestrian detection is standard, even on the base grade GT. That said, it would be good to see blind spot warning and lane keeping assistance fitted as standard (as you'll find on the Benz C200 Coupe). It's not a lot to ask considering these comes standard on higher grades of the Nissan X-Trail.

There are two ISOFIX mounts in the back and two top tether anchor points.

The Mercedes-AMG E53 Hybrid 4Matic+ is covered by a five-year/unlimited km warranty with the high-voltage battery covered for eight years/160,000km. Those terms match the key players in the premium and luxury parts of the market.

Mercedes-Benz ‘Road Care’ assistance is included for the duration of the main vehicle warranty. 

Maintenance is recommended every 12 months/25,000km, with service plans offered across three- ($4110), four- ($5410) and five-year ($7570) periods. That’s an average of around $1350 for the first two and $1500 for the last one. That added powertrain complexity obviously has an impact in the workshop.

The Q60 GT is covered by Infiniti's four-year/100,000km warranty.

Servicing is recommended every 12 months/25,000km. Servicing is capped at $538 for the first, then $643 and then $849 for the third.
