Mercedes-Benz C350 vs Jaguar XJ

What's the difference?

Baby steps these might be, but they're important ones for Benz. The new in-cabin tech and clever engine in the cheapest models only strengthen the C-Class proposition, without taking anything away from the drive experience, cabin ambiance and utterly sublime ride.

In short, Mercedes' reign at the top of the premium mid-size segment is unlikely to be toppled anytime soon.

It might be old and facing German competition bursting with advanced technology, but the XJR is still a car you can buy with heart and head. But mostly your heart. It goes like stink, has a much better interior than the Quattroporte and is more interesting than just about anything this big or this grand.

It's also a better car than the Maserati Quattroporte if you want to get on with the driving yourself and is far prettier than the Porsche Panamera. It's a wonderful thing and even more wonderful that Jaguar continues to build it. Long live that supercharged V8 and the XJ is a great home for it.

Perhaps not quite blink and you’ll miss them, but we're not talking radical changes either, folks. Benz tells us as much as 50 per cent of the C-Class components are new or changed, but it has clearly subscribed to the 'if it ain’t broke' philosophy in the design department.

Yes, there are new bumpers front and rear, new LED light configurations and new colours and wheel designs, but we’re not talking huge changes outside. Still, the C-Class cuts a fine figure on the road, what with its intricate alloys, bonnet-defining grille and simple, understated body contours. Australia will take every available body style, too, including sedan, coupe, cabriolet and - our personal favourite - the 'estate' station wagon.

The C 43 AMG now gets the twin-blade grille design used on the V8-powered models, as well as a two pairs of rounded exhaust tips at the rear.

Inside, though, the changes are more substantial. For one, the new-generation Mercedes Touch Control steering wheel arrives as standard, as does a new and very effective 12.3-inch screen that replaces the traditional dials in the instrument cluster (standard on every model). 

The cabin remains a peaceful and premium-feeling space, with a fine use of materials (including quilted leather on the door panels, polished silver or faux-wood for the centre console and leather for the steering wheel), and Benz deserves credit for ensuring that sense of luxury extends to backseat riders. 

The XJ has a marvellously exaggerated length, with a rear overhang redolent of Jag's sporting coupe and roadster pair of the time of its launch, the XK. There's nothing else in the segment like it, with the three Germans - Mercedes' S-Class, Audi's A8 and BMW's 7 Series - having gone all Hugo Boss and and in the latter two's case, almost shrinking violet. The only credible Japanese alternative, the Lexus LS, looks like a Lexused 7 Series. The XJR is a more emotional car, like Maserati's Quattroporte.

The R adds an aggro grille, 20-inch wheels with low-ish profile tyres, a bootlid spoiler, red brake calipers and vents in the bonnet. Bits and pieces get the black gloss treatment and there are V8 and R badges, as well as a rather large leaper on the bootlid. Capping it all off are four exhausts poking out from the bumper and distinctive vertical taillights.

Inside remains largely unchanged. The cabin is big and luxurious, leather-lined and very, very comfortable. The front air vents have to be modelled on the de Havilland Comet's integrated jet engine intakes and, again, the dash design stays away from the horizontal lines of its obvious competition.

There is probably a bit much chrome for my liking, particularly on the centre console and around the rotary dial shifter, which reflects sunlight into your face during the day.

The lovely 'Riva Hoop' - a band that sweeps from door to door across the top of the dash - is a great touch and remains a defining feature in the cabin. The last update brought an Audi-like digital dashboard, including maps, but it's not nearly as slick as the German. The graphics for the dials are good (and quick) but the maps are a bit so-so.

It all depends, really. All C-Class variants sit on the same 2840mm wheelbase, and stretch 1810mm in width. The sedan, coupe and cabriolet versions measure 4686mm in length, while the Estate’s bigger cargo area increases its size to 4702mm.

Predictably, then, the estate offers the most useable (VDA) boot space, with 490 litres with the rear seats in place, swelling to 1510 litres with the rear seats folded flat. The sedan version is next on the cargo-carrying list, with 455 litres, followed by the 380 litres of the coupe and 285 litres of the cabriolet.

We spent our entire time in the four-door sedan models, and we can report a spacious and comfortable space for driver and passenger (you could play ping pong on the wide centre console) with two cupholders and room in each of the front doors for bottles. There’s all the USB and power connections you might need (most housed in a deep storage bin that separates the front seats) and the more expensive models offer wireless charging for compatible phones, too.

Climb into the sedan’s back seat, and you’ll find impressive legroom (behind my own 176cm driving position), but headroom - especially in sunroof-equipped cars - feels a little tighter. The rear seat is actually wide enough to fit three adults at a pinch, but the tall and bulky tunnel absolutely obliterates leg room for the middle-seat rider.

There are two cupholders in the pulldown divider that separates the backseat, as well two ISOFIX attachment points. Rear occupants also get there own air vents, as well as a 12-volt power source.

It might be over five metres long, but the Jag's cabin isn't as gigantic as that might suggest - luckily, if you want space, the XJ L has it. The SWB version is roomy enough, though, just not palatial. You can fit five people, but the big transmission tunnel will limit the size of that fifth.

Front and rear passengers have a pair of cupholders each, with rubber bubbles to help hold smaller cups in tight. The front and rear doors have pockets but aren't really for bottles.

Boot space is a reasonable 520 litres, with a space saver spare under the floor.

As is expected at this level, Jaguar was not mucking about with price or specification - the XJR starts at a mildly terrifying $299,995, which is very close to the rather more tranquil Autobiography long-wheelbase relax-o-mobile.

Standard are 20-inch alloys, a 20-speaker stereo, power everything with three memory positions, four-zone climate control, keyless entry and start, front and rear parking sensors, heated and cooled front and rear seats, sat nav, LED headlights and DRLs, leather everywhere, auto wipers and (LED) headlights, electric boot lid, heated steering wheel and a space saver spare.

The Meridian-branded stereo is an absolute cracker, powered by the improved but still laggy 'InControl Pro' system. Oddly, it's all crammed into an 8.0-inch touchscreen when there is seemingly room for the larger (and better-performing) 10.0-inch screen. The software is far superior than the version that preceded the last update, but the screen is hard to use, as targets are placed right in the corners and are hard to hit.

Apple CarPlay and Android Auto are also absent, and the sat nav is still fairly dopey.

A long list of options are available, some of which should probably be included in the big sticker price - DAB+ ($620), premium paint is a splutter-worthy $2060 (although, to be fair, the vast majority of the 19 colours are free), adaptive cruise with queue assist ($2200), adaptive headlights a further $2620 and 'Parking Assist', which adds side sensors and a front camera, a further $2780. Reverse cross traffic alert, blind spot monitoring and forward collision warning cost yet another $1460. Ouch.

It’s here where the C-Class is at its most updated, serving up a new turbocharged 1.5-litre hybrid engine in the entry-level C200. Alone, it’s good for 135kW/280Nm, but it’s combined with a clever 48-volt system that adds up to 11kW of bonus power low in the rev range, happily plugging the power void usually left by turbo lag when taking off, or if you plant your foot when overtaking.

The C300 is powered by a more conventional 2.0-litre, four-cylinder good for 190kW/370Nm, while the sole diesel (in the C220d) is a four-cylinder unit that produces 143kW/400Nm. All are paired with a nine-speed automatic transmission.

The C 43 4Matic's engine remains a fabulous thing, only now tweaked for a little bit more power. It's good for 287kW/520Nm, and is paired with a nine-speed transmission that sends the power to all four wheels, albeit with a bias toward the rear tyres.

Jaguar's lovely 5.0-litre V8 with supercharger continues under the XJ's long and shapely bonnet, delivering a walloping 404kW and a tyre-shredding 680Nm. The sprint to 100km/h for all 1875kg of XJR is completed in an impressive 4.6 seconds, which was very competitive at the car's launch in 2009.

Power reaches the rear wheels via ZF's eight-speed automatic and you can control it with the tacky plastic paddles on the steering wheel. Oh, and it has stop-start.

Let’s start with the C200, where the addition of the clever hybrid system has helped drop fuel use to a claimed 6.0-6.3 litres per hundred kilometres. The old car delivered 6.5 per hundred, but was slightly quicker from 0-100km/h (7.2sec- 7.7sec). 

The C300 will sip a claimed 6.5-6.9L/100km on the same cycle, while the diesel requires a miserly 4.7 litres. The C 43 is the thirstiest, of course, needing 9.1-9.3L/100km on the same cycle. 

The C200 makes do with a 41-litre tank (as does the diesel) while the C300 steps that up to a 66-litre tank. And all those numbers related to the sedan body shape, so expect some slight variations if you’re shopping for a coupe cabriolet or estate.

The combined cycle figure for the V8 is listed at 11.1L/100km but fully expect to see the 16.1L/100km we got, especially as you try and fail to tyre of the monstrous power delivery and lovely (if muted) V8 roar.

Luckily, even if you're belting it, the 82 litre tank is a generous size and you'll cover a fair amount of ground.

Keen to sample the new hybrid tech in the C200, we made a beeline for the cheapest C-Class. And if you’d told me, even a handful of years ago, that a piddly 1.5-litre engine would be enough to drag the 1555kg Benz around, I’d have labelled you crazier than Donald Trump's Twitter account. 

The C200’s system is a unique hybrid set-up, in the sense that it only delivers extra power in the tiniest of circumstances, but they’re the areas that it really needs it. From a standstill, the electric motor delivers its extra 11kW of oomph at just the right moment need to help get you moving (the same when overtaking) and it does genuinely make a difference. 

It can’t completely overrule the concrete laws of physics, though. Plant your foot on anything that even looks like a hill and you can definitely hear that 1.5-litre engine working hard - interrupting the ambience of the cabin - but keep it in the sweet-spot of the rev range and it’s a quiet, capable-feeling engine that delivers more punch than its size might suggest.

On Germany’s epic autobahns, the needle even sailed past 215km/h without too much encouragement (even if I could have knitted a sweater in time it took to to close the last 10-or-so-kilometres). Is that relevant for Australia? Sadly not, but it does suggest the engine is more capable than we will ever need it to be.

Elsewhere, the not-too-different C-Class rides an absolute dream, smooth-sailing over bumps and road imperfections, and the cabin is serene and comfortable - though there was more wind noise at times than I was expecting.

Downsides? Well, the cheapest C-Class doesn’t feel the most dynamic offering, with the light steering serving up a slight disconnect between the steering wheel and the road below in its most comfortable settings. Switching to Sport improves matters, but if you’re life is mostly city and suburbs, it will matter little.

The nine-speed transmission can behave oddly at times, too; smooth and lightning fast as it climbs the gears, and mostly perfect on the way back down. But I noticed a definite thump occasionally as it shifted down from second to first gear, which stripped a little refinement from the drive experience.

It's more noticeable in the C 43 4Matic AMG, but it's vastly overshadowed by the thick and meaty power delivery from that stonking turbocharged engine. It's a rocket, and while it's not as fast or as loud as its C 63 big brother, I honestly think the tweaked C 43 is all the AMG I'd ever need.

Indecently quick, surprisingly agile and heaps of fun. While the first descriptor applies purely because of its size, the next two shouldn't when you're in command of 5.13 metres of motor vehicle. As with the Audi and now the 7, the Jag has a lot of aluminium to help keep the kilos off and good gracious, it has worked.

The R is based around the short wheelbase version of the XJ for perhaps obvious reasons. Even so, it appears to be the shorter-again XF's because this thing turns in like a demon. No, it won't stay with the dearly-departed XF-R but it does a mighty fine impression of one, just with a better ride quality.

Rear seat passengers should be prepared to feel a lot of wheelslip, especially when in Dynamic mode, as even the fat Pirelli P-Zero's struggle for purchase when the right foot hits the carpet. The V8 rumbles rather than bellows, but the rears cheerfully spin up until the computers and active differential rein things in. Traction control off and you've got a proper tyre-smoker if you're not playing by the rules. Jag's engineers are clearly hooligans at heart.

As always, ZF's eight-speed transmission does an incredible job of marshalling the horses in a rearward direction and when you're not after a bit of sound and light, have achieved a tremendous amount with the damping. When in normal mode, the car glides along, so much so that the lady of the house wasn't so sure it was a sporting sedan.

Once she was apprised of dynamic mode (you have to cycle the button through winter mode first, for some reason), her only complaint was that it was too long and the steering wheel too big for this type of car. I was persuaded of the latter, especially after stepping out of an Audi S3 which has a tiny wheel. Long story short, the XJR is now 'her' car (to be more accurate, the XFR is, but that hasn't arrived yet, so...), as it felt smaller than it was when not parking and she's a sucker for a torquey V8.

The whole XJ range has six airbags, ABS, stability and traction controls, emergency brake assist, reversing camera, three top tethers and two ISOFIX points. The XJ doesn't have an ANCAP safety rating.

While specific maintenance pricing is yet to be confirmed, each of these models is covered by three-year warranty, with service intervals pegged at 25,000km or 12 months.

Jaguar offers a three year/unlimited kilometre warranty and roadside assist for the same period.

Like the F-Type, XJ owners benefit from three years/100,000km free servicing.
