Mercedes-Benz CLS vs Porsche Panamera: twin test

Displacement-defying frugality? Given Mercedes-Benz is, as we digest these words, amid a distress of recalling scarcely a entertain of a million cars by sequence of a German government, we cunning be astounded to learn we’re not articulate about electronic ‘defeat devices’ here.

What we’re indeed considering is reduction nefarious. That’s since with a CLS 450, a integrated starter- generator mid straight-six engine and nine-speed gearbox is pronounced to urge not usually opening yet also economy. It’s a improved device, all right, yet usually if your foes are dull stifle response and over-abundance explosion during a cruise.

In one form or another, such 48V amiable hybrid systems are unfailing to spin hackneyed in a nearby future. Mercedes’ EQ Boost set-up is partially new to a brand, carrying usually seen movement in a S-Classprior to this third-generation CLS. In a 450 driven here, it feeds an additional 184lb ft into a driveline underneath tough acceleration, afterwards allows for engine-off ‘coasting’ when we come out of a stifle during a canter.

This sole proceed is designed to make a automobile some-more versatile as a whole, nonetheless manufacturers get to collect their battles. In a SQ7, for instance, Audi deploys a 48V complement privately to expostulate a compress electric supercharger that mitigates turbo lag. Bentley needs a additional voltage to induce a span of active anti-roll bars in a Bentayga SUV – useful when we have 2.4 tonnes to manage.

Meanwhile, Volkswagen, Peugeot, Volvo et al see a record as a quick, affordable, arguable repair in creation petrol an appealing mass-market choice to ostracised diesel. Every automobile so given is also means to energy some-more ubiquitous facilities such as a atmosphere conditioning and formidable reserve systems some-more good than is probable with lower-voltage systems, withdrawal a larger fit of a engine’s exertions giveaway to hurl we down a road.

Understandable, then, that a fifth of new cars sole globally are likely to make use of a record within a subsequent 6 or 7 years.

We’re loping west for a event in a Elan Valley with a Porsche – one that, as we’ll discover, creates most some-more of a trait of a hybrid standing than a Merc yet is a likewise niche offering. The 240-mile routeis long adequate to unearth vexations in a automobile that should never vex, and encompasses motorway drudgery, discerning A-roads and even some farming rat-runs that’d substantially pass for ‘green-laning’ among residents of certain postcodes in London.

Today, we have an event to inspect all a sleek, luxuriously sporting four-door tavern – a arrange that dons not usually a smoking coupler yet also regulating spikes – should have in a £60,000-plus locker.

How, then, does amiable hybridisation perceptible in a Mercedes CLS 450 4Matic AMG Line? In mediocre fashion, frankly, that is of march a intention. Were it not for a tiny ‘Power/charge’ sign in one of a digital displays – considerable in their operation yet not for a refinement of their formation into a dashboard mostly carried from a E-Class – we cunning sojourn unconditionally unknowingly of this car’s hybrid standing for, well, ever.

A candid geometric prolongation of a firm’s four-cylinder engine it cunning be, yet this 3.0-litre 6 is a magnificently offset device and sensationally quiet. As a consequence, there’s changed tiny by approach of a feeling evidence as a engine flicks in and out of dormancy while cruising along in a outward line of a M4. The flip side is that this leaves we giveaway to anticipate a boyant that on 19in wheels is most softened over CLS models we’ve formerly tested – ones touting 20-inchers – yet still isn’t as good as you’d expect.

This AMG Line automobile breathes with a topography good adequate notwithstanding a 15mm dump for a normal steel-sprung suspension, yet variations in a peculiarity of a highway aspect intrude. There’s a fidget, a slight shove and yet it’s ethereal adequate to be put to a behind of one’s mind, it’s frequency a pardonable matter during this venerable finish of a market. An E-Class doesn’t do this, and conjunction does an Audi A6, yet an A7 Sportback – a usually loyal opposition for a CLS – positively does. It seems over a wit of a manufacturers to guarantee boyant peculiarity when a car’s roofline gets a bit racy.

The interior is handsome, mind. Moreover, while there isn’t utterly a same clarity that we wouldn’t know even where to start pulling it detached (as we don’t in an A7 Sportback), it’s sturdier than we’ve spin accustomed to from Mercedes. It’s also flamboyant. The somewhat perched seats are bespoke for a CLS and mimicked in a back, that now has a executive berth for a initial time; grainy wooden trim encircles a cockpit in a demeanour that, along with a inexhaustible delivery tunnel, puts me in mind of a 550 Maranello; and a vents do a light uncover analogous to a atmosphere heat they’re vending. Along with remoteness potion and a lead paint, this automobile has yet dual options: a £3895 Premium Plus and £1695 Driving Assistance Plus packages.

The former includes a top-spec Comand Online infotainment, a 590-watt Burmester sound system, keyless go, a sunroof and Mercedes’ 360-degree camera, that is useful for a automobile longer, wider and taller than a one it replaces. The latter equips a CLS with a progression of reserve technology, some it useful (active blind-spot assist), some of it not (active lane-keeping assist, essential for half an NCAP star…). Shouldn’t itbe thrown in for ‘free’ during this level? You cunning consider so.

Our ride-related concerns notwithstanding, by a time those wide-spaced headlights are steering onto a labyrinth fibre of a A479, a CLS has finished changed tiny to disprove itself as a strident family grand tourer. Leading north- west from Crickhowell and into a extraordinary immature of Wales proper, it’s on this highway that a Mercedes afterwards cements itself as a estimable all- rounder. It goes neglected on a motorway yet 362bhp and, some-more tangibly, 369lb ft from usually 1600rpm is adequate to give a two-tonne exec a slap-bang spin of real-world pace. This engine will spin to a 6250rpm redline, too, yet you’ll find yourself inhabiting a torque-rich mid-range since that’s how a CLS 450 likes to be driven.

The steering is good weighted and predictably geared (no guarantees of that on full-fat AMG models), permitting we to place a large automobile with gratifying ease. The accepted prodigy is compensation rather than delight, a energetic mettle being one of cunning rather than exuberance. Driven within itself, this framework is staid and wants nought for traction. Up a ante and a front spindle indolent in a response, joined with no tiny volume of cessation float, tells we all we need to know.

In shooting-brake Sport Turismo form, a Panamera 4 E-Hybrid accessible a CLS seems hewn from slab in a demeanour same to a Elan’s Victorian bridges. The Mercedes is off-hand by comparison and it’s a identical story on a spec sheet. Both cars use electric and combustive force to expostulate all 4 wheels by their gearboxes, yet in a Porsche a 2.9-litre twin-turbo V6 and electric engine mix to broach 456bhp and 516lb ft. We know a Panamera has a terrific, communicative framework too, so it’s no contest, surely?

Not during initial it isn’t. After a CLS, slumping into a Panamera’s low-slung seats feels like slipping into a fit of armour. The steering edge is slim, organisation and rotates with suggestive insurgency and frail response. The orchestration – digital, save for a executive tachometer – is slick, even if a potion touchscreen does uncover adult fingerprints. The cliff-face lurch and high skip instil something of a outpost genius and when we step off a mark, we do so in nearby overpower as a drivetrain defaults to electric mode.

The Sport Turismo is a likeably off kick beast, a black form resting tighten to a highway on adaptive atmosphere cessation and embellished out with tiny fluoro-green details. When a Birmingham Corporation Water Department assembled these reservoirs, we can gamble they didn’t reckon on anything this far-reaching regulating a bridges. The Panamera seems to enhance into any accessible highway space on offer, and even on A-roads it’s not odd to see a smoke of dirt kicked adult by a gutter-grazing behind tyre. It’s a 2.2-tonne kerb weight that does for a camel’s behind in a end, though.

There are several modes for powertrain and suspension, and when a V6 wakes up, it does with desirable belligerence, yet there’s no evading a clarity that, usually maybe, Porsche has bitten off some-more than it can gnaw with this car. What 30 or so miles of pristine electric operation adds in terms of economy and, in truth, newness is to a wreckage of a impetus from a over-abundance bulk and increased open rates.

It’s transparent conjunction of these cars is yet important fault. The Panamera has extensive extent – such that maybe usually Porsche could broach – and doesn’t let hybrid weep forestall a attempts to interest to drivers. That interest is sullied a touch, however, since a physics- defying panache a Panamera summons along a widen that’s quick, broad, well-spoken and predicted adequate to play to a strengths is simply too intermittent. The rest of a time, you’re left with an sincerely organisation automobile that struggles to take a unaffected position by corners. Turn-in contingency be instigated usually so, and a upper-body examination can spin draining, yet it stays absolutely a higher driver’s car.

But a improved automobile to live with?

Not this time, since a Mercedes is usually happier in a frozen yet partially typical skin. It’s also a some-more careful automobile and easier to beam along British roads. If a cessation could usually control itself as fluently as a crankshaft, it would be a gentle victor. As it stands, it scrapes a win, yet both Stuttgart and Weissach have room for alleviation in a electrified oppulance automobile game.

1st – Mercedes-Benz CLS: Slower and reduction involving than a opposition yet a some-more finish o ering nonetheless

2nd – Porsche Panamera: Remains prodigiously adaptable, yet a weight blunts a doing and compromises a ride

Speccing a CLS: 

That a latest CLS advantages from a 19in wheels (complete with noise-suppression foam) instead of a some-more appealing 20in equipment is immutable. Whether or not we should select a adaptive atmosphere cessation is another matter.

The hardware copes good when the going is smooth, yet we’re not assured anybody profitable this most income should have to put adult with a hollow, loud opening on coarser surfaces. Low-speed miscarry is also problematic: city- dwellers cunning be improved off with a pacifist set-up of a exam car.

Four-door coupes on a budget: 

Can’t widen to possibly of a glam new cars? Here are some used alternatives that are rather some-more affordable

MERCEDES CLS: Prices for a exam car’s prototype start during £11k — hardly plausible given a glamorous looks and boutique hotel interior. Even a sound 350 CDI with thumping V6 diesel, low mileage and full story can be had for £14k.

VOLKSWAGEN PASSAT CC: These early CCs are some-more than usually a melted Passat. Adaptive cessation guarantees a comfy boyant and, of course, we get a top-quality interior with loads of toys. Yours for usually 5 grand with important mileage and history.

BMW 6 SERIES GRAN COUPE: If we don’t imagination an oil-burner, a large Six is a one to have. Mind you, a diesels are flattering good too, so we can’t go wrong. Bag a 640i with story and an normal mileage for £22k, or a 640d for a smidge less
