Ferrari 296 vs Mercedes-Benz Gls450

What's the difference?

Anyone who says electrification somehow muddies the Ferrari formula is wrong. This plug-in Prancing Horse is among the most potent and direct vehicles I’ve ever driven, and the electric motor only adds to the experience.

The GLS450d impresses as an entry-level grade, as it’s a more family-friendly allrounder than the specialised AMG and Maybach variants. Its combination of a torque-rich diesel 48V hybrid drivetrain, air-cushioned suspension and plush interior are as well suited to luxury urban travel as they are to grand touring, where its heavy towing and generous load-carrying capabilities can shine. Whether it’s worth around $200K drive-away, only those who shop at the top end of town can decide.

It is hard not to swoon when you gaze upon the 296 GTS, and I say that with no bias - I don’t think all Ferraris have looked this good.

But this is Ferrari at its dreamy, sweeping best, from the tarmac-kissing front — which generates so much downforce and cooling it negates the need for active aero — to its swollen haunches and the glass-topped engine window.

So what’s the difference between this and the GTB? Largely it is the ability to drop the folding roof, meaning you can feel the wind in your hair and that exhaust in your soul. To be honest, though, I reckon it looks better top up...

It’s a cockpit-style driver’s set-up inside, and there’s lots I love and some things I don’t. But let’s start with the steering wheel, which might be one of the best in existence.

It feels magic under the touch, as do the giant flappy paddles which remain fixed in place as you turn the wheel.

It’s also surprisingly comfortable in the figure-hugging sports seats, though climbing in and out of them is not necessarily something you want to do in front of a crowd.

Downsides? There is plenty of tech in the 296 cabin, but it’s all controlled from the steering wheel, making it fiddly and annoying to use.

Also, there are F1-levels of complexity on the control-everything steering wheel, and if I’m being honest, there are some buttons or switches, the function of which I still don’t fully understand.

This is an imposing vehicle in extravagant S-Class tradition, riding on an expansive 3135mm wheelbase and stretching more than 5.2 metres (5215mm) long and more than 2.0 metres (2030mm) wide with a turning circle that's nudging 13 metres.

However, it’s just under 1.8 metres (1798mm) tall, so there’s no clearance issues when accessing multi-storey carparks. And with its side-steps (or ‘running boards’ in nostalgic Benz speak) most adults can step rather than climb aboard, although passengers of shorter stature during our test noted that assist handles on the A and B pillars would be handy.

Central to its sophisticated chassis design is adaptive air suspension, which uses a pneumatic or ‘airbag’ form of springing with adaptive damping to continuously optimise ride comfort and handling response according to road conditions and driving dynamics (see Driving).

The GLS’s styling is clean and uncluttered with tasteful restraint evident in its chrome and satin-chrome highlights, yet it projects a majestic quality with its prominent four-louvre grille and elegantly spoked alloy wheels.

The spacious and sumptuous seven-seat interior is visually pleasing and practical, with a subtle blend of surface treatments, contrasting tones, lots of soft-touch surfaces and exposed stitching. This is combined (thankfully) with physical dials, switches and ‘piano key’ buttons to control numerous interior functions, in preference to distracting touchscreen prompts.

What do you want to know around practicality? We’re talking two seats, about 200 litres of cargo space total and a couple of smallish storage spaces in the cabin. And… that’s about it.

Next question, please.

Although it has a hefty 2655kg kerb weight, our test vehicle’s 3420kg GVM rating provides a useful 765kg of load capacity, which should comfortably absorb the combined weight of up to seven occupants and light luggage. Or with the third row of seating folded, five occupants and heavier luggage.

It’s also rated to tow up to 3500kg of braked trailer and with its sizeable 6920kg GCM (or how much weight it can legally carry and tow at the same time) it can carry its maximum load while towing its maximum trailer weight.

So, that’s commendable practicality, given it would be well suited to owners that need to tow large caravans, boat trailers, horse floats etc in style without having to compromise much (if at all) on either passenger numbers or luggage capacity.

Driver and front passenger space and comfort is exceptional, as you’d expect. Storage includes a large glovebox plus a bottle holder and bin in each door. The front of the centre console has two USB-C ports, wireless phone charging and heated cupholders, while the rear of the console has a large storage box with a third USB-C port and padded lid that doubles as a comfy elbow rest.

Even tall passengers in the second row of seating enjoy spacious comfort, given I’m 186cm and with the driver’s seat set in my position I have ample knee clearance, foot room and head space.

However, the central passenger must contend with a transmission tunnel in the floor and shoulder room would be squeezy for three large adults, which is okay for short trips but a maximum of two would be ideal for longer journeys.

The rear of the centre console also treats second-row passengers to a pair of USB-C ports, adjustable air-vents and a control panel that allows independent climate adjustment.

There’s also a large bin/bottle holder in each door plus storage nets on each front seat backrest. The centre seat backrest folds flat to allow long items (skis etc) to slot between the outer backrests. And it also serves as a fold-down armrest, containing two cupholders and a lidded slimline compartment that’s ideal for hidden phone storage.

The third row is uncommonly spacious, even for tall people, with padded armrests on each side containing cup holders and twin USB-C ports.

The carpeted rear luggage area has four load-anchorage points, a first aid kit and 12v socket. With the third-row seats upright it offers 355 litres of load volume, which increases to 1350 litres with the third row folded and 2400 litres (or 2.4 cubic metres) with both the second and third rows folded.

Our Polar White test vehicle, which is the base grade in the three-tiered GLS range, comes standard with a 3.0-litre inline six-cylinder turbocharged diesel engine with 48V mild hybrid technology, nine-speed automatic transmission, permanent all-wheel drive and active air suspension for a list price of $189,100.

This pricing is higher than comparative entry-level grades offered by the two marques which dominate sales leadership in this segment, comprising the BMW X7 xDrive40d M Sport ($179,500) and Lexus LX500d AWD ($158,700).

The GLS450d’s standard features include 22-inch AMG alloy wheels with Continental 325/40 R22 tyres and a collapsible spare, ‘AMG Line’ body styling enhancements, aluminium-look illuminated side-steps with non-slip rubber studs, multi-beam LED headlights and more.

Step inside the keyless interior and you’ll find ‘Hey Mercedes’ voice activation, fingerprint scanner (which memorises individual comfort settings for up to seven users), panoramic sunroof, heat-insulating dark-tinted rear privacy glass and the ‘Premium Plus Package’ that includes heating/cooling for the front seats, heated rear seats, head-up display, separate front/rear climate control zones, heated cupholders and more.

There’s also a concert hall-like Burmester surround sound system controlled by a central touchscreen with digital radio and Apple CarPlay and Android Auto connectivity, plus wireless phone charging, multifunction Nappa leather sports steering wheel and USB ports front and rear.

Driver assistance includes the ‘Parking Package’ (360-degree camera, active parking assist and transparent bonnet), ‘Mirror Package’ (auto-dipping rear-view mirror and electric folding door mirrors with puddle lamp projection of the brand logo) and ‘Driver Assistance Package’ (blind-spot assist, exit warning, speed sign recognition, lane keeping etc) all included as standard equipment.

Of course, Mercedes-Benz offers numerous extra-cost options including a 3500kg towing package plus interior, exterior, suspension and wheel enhancements (including Nappa leather trim) for those who want their GLS with the lot, which can easily push the list price beyond $200K.

Now we're talking. The powertrain here is both tremendous and terrifying, pairing a 3.0-litre twin-turbo-petrol V6 with a rear mounted electric motor, and a 7.5kWh battery, to deliver a total 610kW and 740Nm. That power is fed through an eight-speed dual-clutch auto transmission.

Those are, frankly, scary numbers, and enough, Ferrari says, to dispatch 100km/h in just 2.9 seconds, and to push on to a top speed of 330km/h.

The GLS450d comes standard with a 3.0-litre turbocharged inline six-cylinder diesel producing 270kW of power at 4000rpm and 750Nm of torque between 1350-2800rpm.

This is paired with a 48V mild-hybrid system comprising a 48-volt battery (charged by regenerative braking) and an integrated starter-generator which provides both seamless engine stop-start and up to 15kW/200Nm of extra power and torque during acceleration.

A nine-speed torque converter automatic provides the choice of manual shifting using the steering wheel-mounted paddles, along with several selectable drive modes.

The active all-wheel-drive system continuously adjusts the engine’s torque delivery between front and rear axles (and individual wheels as needed) to maintain optimum traction and handling.

As well as the ability to start up and slink away silently, the Ferrari 296 GTS’s little battery will deliver a 25km EV-only driving range, and contribute to the overall claimed fuel use of just 6.5L/100km.

Charging is AC only, and the the brand reckons it takes around 90mins to top up using an 11kW charger. The self-charging is on-point, though, with the Ferrari able to quickly recoup energy from braking and the like to top up the battery without needing to plug in.

Mercedes-Benz claims official combined consumption of 7.8L/100km and the dash display was showing 9.0 when we stopped to refuel at the completion of our 368km test, which included the usual mix of suburban, city and highway driving with up to five passengers at times and light luggage.

Our own figure, calculated from fuel bowser and tripmeter readings, was close at 9.5 which is outstanding sub-10L/100km economy for such a substantial vehicle in mostly metropolitan use. Therefore, based on our own consumption figure, you could expect a real-world driving range of around 950km from its 90-litre diesel tank.

The engine is undoubtedly a highlight, and we’ll get to that in a moment, but I first want to talk about the steering in this car.

It might sound like a weird point to get hung up on, but it is sensational, and maybe the best I’ve ever experienced. Generally speaking, super-responsive steering can risk feeling overly sharp and uncomfortable when cruising, but somehow the 296 manages to feel super natural, super responsive, and super engaging, without every feeling sharp or darty. It’s just predictable, responsive, and spectacular. 

Honestly, it is a highlight of a drive experience filled with highlights, with another being the dual-nature of this drop-top supercar. Long before I got anywhere near a twisting road I needed to navigate the usual nightmare that is Sydney, tackling traffic, suburbia, freeways, tunnels and expansion joints galore, and the 296 never felt uncomfortable.

Instead, the 296 slipped into a comfortable kind of lope, never jarring or rough, and eminently easy to get along with. And yet, when you arrive on the right road that veil of sensibility drops, and the Ferrari quickly reminds you of its potential.

For a start, the acceleration is properly, startlingly aggressive. Engage the 'Qualification' drive mode (which unlocks the full might of the Ferrari's electrified powertrain) and flatten your right foot, and you'll find the world suddenly hurtling past your windows, and your knuckles will no doubt whiten as you feel the rear tyres fighting for traction against the onslaught should you try it on anything but the straightest of roads. 

It's addictive, but it's just one element of a near-perfect combination on offer here, with the 296 GTS the stiffest Ferrari drop-top to date, which becomes immediately clear as you start to attack corners with ever-growing confidence.

Grip, stability and stiffness in spades, the GTS delivers. And all accompanied by an exhaust howl so angry and evil it’s hard to believe it’s being generated by a V6.

It’s a thing of very near perfection.

It’s an enjoyable vehicle to drive, with multiple power adjustments for the seat and steering wheel combined with a large left footrest which provide supreme driver comfort and support.

The powerful and responsive turbocharged six-cylinder diesel and nine-speed auto are well suited to this application. The engine’s ample torque provides spirited acceleration from standing starts, taking only six seconds to reach triple-digit speeds.

This drivetrain would be well suited to heavy towing duties, given the 48V mild-hybrid system can contribute an extra 200Nm (in addition to the engine’s 750Nm), which raises the total theoretical torque output to almost 1000Nm.

The active air suspension provides a wonderfully cushioned ride that floats over bumpy roads, while maintaining excellent handling response and surprising agility. These commendable chassis dynamics, combined with the powerful and responsive drivetrain, makes the vehicle feel smaller and lighter than its dimensions and kerb weight would suggest.

Overall, it’s difficult to fault from a driver’s perspective, with the only exception being the voice activation function. This is often triggered by words or phrases other than ‘Hey Mercedes’ resulting in regular interruption of conversations. This needs some fine tuning.

The GLS does not have an ANCAP rating as it’s yet to be tested, but comes standard with a suite of passive and active safety features including nine airbags, auto emergency braking (AEB) with pedestrian detection and junction assist, blind-spot monitoring, traffic sign recognition, head-up display, rear cross-traffic alert, lane-keeping, adaptive cruise control with ‘distance assist’ (autonomously brakes/accelerates in heavy traffic), front/rear parking sensors, 360-degree camera and more.

There’s also two ISOFIX and three top-tether child seat anchorages in the second row, plus two more of each in the third.

Standard is a three year warranty, but you can extend that for up to five years. Then, if your car has less than 90,000km on the clock, you can opt into the 'New Power15', which gives you up to 15 years total warranty coverage and is fully transferable.

The first seven years scheduled maintenance is free-of-charge.

The GLS comes with a five-years/unlimited km warranty (better than BMW and Lexus) and five years of roadside assistance. Scheduled servicing is every 12 months/25,000km whichever occurs first.

Mercedes-Benz offers capped-price pre-paid servicing packages with three, four or five-year terms. For example, the total upfront cost of the minimum three-year term is $4090, or an average of $1363 per service.
