Jaguar F-Type vs Mercedes-Benz SL-Class

What's the difference?

The Jaguar F-Type R is as fast and capable as it is beautiful. Although it's a little thirsty and comes up short on active safety, it's technically outstanding, delivering a stunning mix of performance, dynamics, and comfort.

The SL's overall score is somewhat skewed by everyday concerns, and rules are rules - an average punter will find the price of this car somewhat confusing and the devil-may-care attitude to fuel consumption bewildering.

If neither of these things are a problem, then the SL63 makes plenty of - well, not sense, because it's not a particularly clever or considered car - but it fills a niche that not so long ago we all thought would go the way of the dodo.

The fact it sells so few examples is betrayed by some of the cabin amenities and the fact that Mercedes hasn't put much effort into reducing the car's weight to improve its consumption or sharpen up the handling.

The fact it still exists at all is pretty damn cool, though, and for certain people an SL63 purchase is the culmination of a lot of hard work.

If it is your dream car, the SL63 won't disappoint. Everyone who rode with me said it was mightily impressive, but you've got to really want it. When you're not far off buying a Ferrari California T or Aston Martin V12 Vantage S for the money, you'll need a real yearning for the three-pointed star to go this way. And if you do, good luck to you - you've probably worked quite hard to get here.

Although it kicked off as a roadster, a coupe version of the F-Type was always part of the plan. In fact, Jaguar's C-X16 concept, that in 2011 previewed the eventual production car, was a hardtop.

Following the Coupe's public reveal at the 2013 Los Angeles motor show, I asked Jaguar's then head of design, Ian Callum, if the bean counters had vetoed the concept's ultra-cool side-opening hatch door; one of many styling hat tips to the E-Type. His response was a wry smile and slow nod of the head.

It's a shame that door didn't make it to the showroom floor, but the E-Type is still a strong design influence on its successor.

At close to 4.5m long, around 1.9m wide, and a fraction over 1.3m tall, the F-Type R looks more compact in the metal than it does in photographs, arguably the hallmark of a successful sports car design.

A long, flowing (front-hinged) bonnet (Jaguar calls its shape 'liquid metal' sculpture) projects forward from a rear-set cabin, with broad but tightly wrapped haunches behind it. The 20-inch, 10-spoke rims (in 'Gloss Black' with diamond-turned finish) fill the wheel arches perfectly.

I'm a huge fan of the tail-light cluster design, subtly reprofiled in the late 2019 update, which echoes the shape of the Series 1 E-Type and other classic Jags, but found it harder to warm to the outgoing F-Type's squarish headlight treatment.

Always a subjective call, but to my eyes this car's slimmer, more feline (LED) eyes and ever-so-slightly larger grille deliver a better front to rear balance. And slender, flush-fitting pop-out exterior door handles remain sub-zero cool.

Our 'Santorini Black' test car had been optioned with the 'Exterior Black Design Pack' ($1820) for an extra hint of menace. It applies body-colour to the front splitter, side sills, and rear diffuser, at the same time blacking out the grille surround, side vents, side window surrounds, rear valance, Jaguar script, F-Type badge and 'Leaper' emblem.

Jaguar describes this two-seater as a '1+1', confirming the F-Type's focus on the driver, and our test car's tan leather interior emphasises the fact.

Tan dash on the passenger side, complete with flying buttress-style grab handle for extra support when g-force starts to build. Contrasted by all black and all business on the driver's side.

A broad centre stack houses the 10-inch multimedia touchscreen, with easy-to-use dials for the climate control system below. And the 12.3-inch reconfigurable hi-def instrument cluster (with graphics unique to the F-type) is a model of clarity and simplicity.

The latter offers a choice of display themes, including full nav map, but the default mode highlights a large central tachometer. Nice.

An impressive design feature carried over from the previous model is deployable front air vents. The dashtop remains flat until a given climate control temperature setting causes an upper section, housing a pair of adjustable vents, to gently rise. Very cool (no pun intended).

The SL has always been completely unapologetic about its size and seems to be designed to accentuate rather than hide its length and width. The long bonnet screams power and prestige, and get out of my way, and is reminiscent of the little-loved McLaren SLR project of some years ago.

The size of the Mercedes logo on the huge front grille leaves you in little doubt about the brand of car that’s about to pass you at speed and some might say (okay, I would) that its large surface area is a little vulgar.

Like the SLR, the design doesn't seem to have a particularly cohesive strategy, with a number of Mercedes elements from around the traps that climb over each other. Roof up it looks awkward because of the gigantic posterior while with the roof down it looks overly long and, again, tail-heavy.

Folding hardtops are notoriously cumbersome and need a lot of room to hide them, but the silent operation is something to behold.

Elements that are worth deleting if possible are the dodgy 'Biturbo' badges. It's that kind of bling that gets people raising their little finger at you.

If you're intending to daily drive your F-Type R, make sure your yoga fees are up to date, because entry and egress are for the fleet of foot and flexible of limb.

Once inside, though, within the bounds of its two-door coupe format, the F-Type offers an array of storage options, including a decent glove box, centre storage box/armrest, small door bins, a netted pocket on the top of the bulkhead between the seats, and a pair of console cupholders.

Power and connectivity runs to a 12V socket in the dash, with another in the central storage bin, alongside two USB-A ports, and a micro SIM slot.

Notwithstanding the (alloy) space saver plonked on the boot floor, the F-Type Coupe delivers worthwhile cargo space, with 310 litres on offer, rising to 408 with the load cover removed.

That's enough to swallow small (36-litre) and large (95-litre) suitcases together, and there are two (nicely chromed) tie-down anchor, as well as elasticised retaining straps at either end of a small ledge on the bulkhead.

“Practicality” is about as relevant to this car as a code of ethics is to a drug dealer or a contract killer, because the SL63 buyer is hardly worried about cupholders and boot space. For what it's worth, there are four cupholders in the two-seater cabin (which might explain why owners aren't worried about their liquid carrying prospects) and a minimum boot space of 364 litres and a maximum - with roof up - of 504, which is actually not bad.

Cleverly, there's a little robot-operated luggage cover inside the deep boot that stops your gear from being crushed when the roof goes down.

There's also space in the long doors where you might secrete a bottle of wine that would get a NSW Premier fired if he thanks you for it, and a bin in the console to hide your phone.

It’s difficult to ponder the idea of value when a car is already approaching $400,000 at a rapid rate even before you start piling on the options. On the plus side, for a list price of $368,715 you do get an extremely long list of standard equipment.

The SL has always been completely unapologetic about its size.

Edited highlights include leather on almost every available surface, heated and cooled electric seats with a fan heater for your neck, a B&O stereo that will shatter the windscreen on request, aluminium trim that's real aluminium (mostly), Active Ride suspension, sat nav, dual-zone climate control, active cruise, LED headlights and a huge swag of safety gear.

The 12-speaker stereo also has DVD, limited smartphone integration via Mercedes' COMAND system, a seven-inch screen and, of course, Bluetooth.

The F-Type R is powered by Jaguar's all-alloy (AJ133) 5.0-litre supercharged V8 engine, featuring direct-injection, variable (intake) cam timing, and an Eaton (Roots-type) blower to produce 423kW (567hp) at 6500rpm, and 700Nm from 3500-5000rpm.

Drive goes to all four wheels via an eight-speed 'Quickshift' automatic transmission and Jaguar's own adaptive AWD system with 'Intelligent Driveline Dynamics' (IDD).

The AWD system is based on an electro-hydraulic multi-plate (wet) clutch, controlled by a centrifugal electro-hydraulic actuator. Default front/rear drive balance is 10/90, although Jaguar claims even a full shift of power from 100 per cent rear to 100 per cent front takes just 165 milliseconds.

The IDD system continuously monitors each wheel's speed and traction, suspension compression, steering angle and braking force, as well as the car's rotational state.

It then uses an algorithm to determine which wheel(s) are likely to lose traction, and before grip is lost, transfer drive to the wheels that can make best use of it.

The SL63 is powered by Mercedes’ increasingly famous V8, with two turbos along for the ride to add oomph and cut the car's famous consumption, at least slightly. The 5.5-litre unit produces a massive 430kW and a scarcely believable 900Nm of torque.

All of that heads rearward via a seven-speed dual-clutch transmission that helps sling the 4.6m, 1848kg machine to 100km/h in 4.1 seconds.

Claimed fuel economy for the combined (ADR 81/02 - urban, extra-urban) cycle is 11.3L/100km, the F-Type R emitting 269g/km of CO2 in the process.

Despite the standard auto stop/start function, over close to 350km of city, suburban, and freeway running we recorded a (dash-indicated) average of 16.1L/100km.

That's a solid drinking habit, but it kind of goes with this performance territory, and we did lean into the throttle on a regular basis.

Recommended fuel is 95 RON premium unleaded, and you'll need 70 litres of it to fill the tank. That equates to a range of 619km in line with the factory claim, and 434km using our real-world number as a guide.

Much as is the case with the price, there's no real way to soften the blow here - the SL63 drinks like a footballer on Mad Monday, except it does it every day. The official combined cycle figure of 10.2L/100km is quite easy to double, as we did, averaging 21L/100km in mostly flowing suburban traffic. In the car’s defence, the accelerator pedal spent a good deal of time near the firewall.

The SL does have stop-start to help reduce its considerable environmental impact.

Yep, no surprise, the 2021 Jaguar F-Type R is a proper, rip-snorting, beast of a machine. Weighing in at just over 1.7 tonnes, with 423kW/700Nm to propel it forward, in terms of straight line acceleration, it's every bit the scalded cat.

Bury the right foot and it will storm from 0-100km/h in just 3.7 seconds, with furious aural accompaniment courtesy of the 4.0-litre supercharged V8 and sports exhaust system. Electrically-actuated bypass valves in the latter's rear silencer remain closed until they automatically open under load, and boy, do they open up.

Prospective F-Type R owners wishing to remain on good terms with their neighbours will be pleased to know there's a 'Quiet Start function', but once you're a few blocks clear the engine is capable of alerting the entire suburb to you presence, complete with raucous crackles and pops on the overrun.

All 700Nm of maximum torque is available from 3500rpm through to 5000rpm, and mid-range thrust is ferocious. If you have access to a long enough private road Jaguar claims this car will storm on to a (electronically-limited!) maximum velocity of 300km/h.

The eight-speed auto transmission has picked up several tweaks courtesy of the XE-based SV Project 8, and it's brilliant. A conventional torque-converter based unit, rather than a dual-clutch, it's dubbed 'Quickshift', and that it does. Manual flicks between ratios, using the wheel-mounted paddles, are rapid and positive.

Head for your favourite B-road, and it's the F-Type R's ability to put every bit of its power down, without fuss, that impresses next. Push into a series of tight corners and the car grips, settles, and simply surges from one bend to the next, the tricky AWD system seamlessly shuffling torque between the axles and individual wheels.

The standard electronic active diff, and torque vectoring (by braking) also help keep everything under control, turning backroad tryhards into apex hunting virtuosos.

Suspension is by (aluminium) double wishbones front and rear, with revised springs and anti-roll bars added in the 2019 upgrade. Continuously-variable dampers underpin the 'Adaptive Dynamics' system, learning your style and adjusting accordingly.

The electrically-assisted power steering combines great road feel with satisfying accuracy, and the car feels balanced yet agile and responsive in enthusiastic driving.

In a more relaxed mode the adaptive set-up detects rough road conditions and adjusts the suspension settings for greater ride comfort. According to Jaguar, the damper valves and control algorithms have been recalibrated to improve low-speed comfort and high-speed control, and I can vouch for their effectiveness.

Not long after steering this F-Type R I spent some time in the supercharged V6 F-Type P380 R-Dynamic, and this R is far more compliant.

Rubber is a specially-developed Pirelli P Zero (265/35 fr - 305/30 rr), and the supremely efficient brakes are ventilated 380mm at the front, and 376mm rear.

There are a number of impressive things about the way the SL drives. Firstly, astronauts will be familiar with the galactic thrust of the V8. It seems endless, seamless and ready to sling the big coupe into the outer atmosphere. Few engines of any kind can match the relentless go on offer in the SL and much of the credit should go to the seven-speed twin-clutch transmission.

When you jump on the brakes and shift down, the exhaust keeps the show going with angry crackles and pops.

Containing a torque figure like the twin-turbo V8's requires a lot of electro-trickery to stop you from being launched off the road. The great thing about all that stuff is that it works unobtrusively and smoothly.

Mashing the carpet in an SL without traction control would create much sound and smoke but little forward progress, such is the twist on tap. The SL has a range of modes from full-nanny (which is meant to keep you on the slippery Alpine road you've chosen to get you to some Swiss ski resort) while turning the dial all the way around to Race loosens the bonds.

It's in this mode you'll have the most fun and it does seem that the intermediate settings are a bit of a waste of time. Race mode does little to diminish the amazing ride quality provided by the active suspension setup, but relaxes the reins on the huge rear tyres. Exiting roundabouts is suddenly a huge laugh, with the tail cheerfully breaking traction and the two-mode exhaust thundering in a most pleasant way.

Better still is that when you jump on the brakes and shift down, the exhaust keeps the show going with angry crackles and pops, with more on the way when you lift off. There's little to match the aural pleasures of a properly tuned V8 and Mercedes has resisted the temptation to quieten it down on the outside and generate a fake noise for the inside. Although that would be stupid in a convertible, if you think about it.

The SL63, despite its AMG badge, isn't about all-out handling, of course. The Ferrari California would definitely show it how it’s done on a winding country road. The SL is more about flow, building momentum and rarely shifting down to second gear. The monstrous torque is enough to keep things rolling but should you wish for a bit more of the exhaust bellow, second is there for the taking.

Hustling the big convertible feels wrong, not because it can't do it, but because it's not really what it's for. Having said that, it offers a kind of fun that nothing else on Earth will provide, not even a Bentley GTC.

With the roof up, the SL63 is a quiet place but not remarkably so. The huge sticky tyres do the cabin's hush no favours, with an annoying roar on a wider range of surfaces than you might expect.

Roof down, it's hardly a paragon of virtue. A lot of wind noise reaches the cabin, even well below the huge speeds the SL can reach. So if you want to talk, it's windows up you'll need to deploy the mesh screen that bridges the roll hoops.

Six airbags, ABS, stability and traction controls, blind-spot sensor, lane-departure warning, brake assist, active safety bonnet, lane-keep assist, driver attention detection, AEB.

Jaguar covers its Australian new car range with a three-year/100,000km warranty, which looks particularly stingy next to the mainstream market norm of five years/unlimited km, and lags other premium players like Mercedes-Benz and Genesis, both sitting at five years/unlimited km.

On the plus side, paint and corrosion (perforation) are warranted for three years, and roadside assistance is complimentary for 12 months.

And on the big plus side, scheduled servicing for the F-Type (determined by an on-board service interval indicator) is free-of-charge for five years/130,000km.

The SL63 is covered by Mercedes' three-year/unlimited kilometre warranty. And, er, that's it.
