German super-sedans pack performance, styling tweaks

Updated BMW M5 and Mercedes-AMG E63 maintain their parity in powerhaus pedigree.

FOUR Twenty, 441, 450, 460 – pick a number, right?

Always with awareness that where you land on the kiloWatt chart also dictates one of two badge preferences when selecting a German premium all-paw performance sedan that’s not an Audi.

The first and third counts put you with Mercedes AMG, and behind the wheel of an E63 AMG in standard and S formats. The remainder with a Five Series fettled by BMW’s M Division, primarily as the ‘starter’ edition, ultimately in Competition mode.

Yup, it’s mid-life upgrade time for two supercar-slaying sedans and, as always, where one goes, the other is quick to follow, with both laying down big numbers.

Which also relate to? Well, torque, which optimally hits 750Nm behind the blue and white roundel and 800Nm behind the star, top speeds - 300kmh optimally from the E63 S, another 5kmh more with the Competition (with the optional M Driver’s package fitted) – and, of course, those all-important 0-100kmh times: just 3.3 seconds for the M5 in hottest fettle, which makes it 0.1 faster to the legal highway limit from a standing start than the most potent E 63. There are economy figures too but … not of any particular interest, right?

So, which to chose? It might all come down to price, which is still a mystery for our market, though potentially the current stickers won’t be too far shy of the new prices, and availability … which means quarter three for the Munich monster, some time prior to Christmas for Affalterbach’s.

The other important thing to recognise is that, while both makes are talking of these incoming missiles as being ‘new’ models, they really mean ‘massaged.’ Quite subtly, for the most part.

Those twin turbo V8 engines – a 4.4‑litre from Beamer, a 4.0-litre out of the other crowd – gearboxes (eight‑speed auto with BMW, nine-speed AMG), and the fancy all-wheel-drive - that can be configured in a special rear-drive mode with the M5 - are all as before.

What’s incoming is the same range of minor cosmetic updates found on the recently revised 5 Series So the M5 now sports the updated kidney grille which extends a little further down into the bumper and has a one-piece chrome surround. The new front end gains larger air intakes at the sides while the main aperture is now hexagonal. The LED lights front and rear are new, as is the rear bumper.

Interior revisions also mirror those on the standard 5 Series, with buyers getting a new 12.3-inch digital instrument cluster and a larger infotainment screen. Electrically adjustable sports seats and sun protective glass come as standard, while a Harmon/Kardon stereo, head-up display and an Alcantara headlining can be specced as optional extras, as can a Technology Plus pack that adds front and rear seat heating, a heated steering wheel, soft close doors and a seat massage function. The M5’s Ultimate Pack builds on this specification with a carbon fibre engine cover and Bowers and Wilkins surround sound system. A lot of comforts for a performance car? That’s your modern M5 customer.

There is a new 20-inch wheel design while the brake calipers can be finished in black or red as an alternate to the usual blue. The Competition’s are gold, as before.

Chassis upgrades over the standard BMW 5 Series include uprated dampers, stiffer engine mounts and larger disc brakes, with fixed six-piston calipers up front and single piston calipers at the rear. Buyers can also opt for a range of M Performance extras, such as coilover suspension and carbon fibre aero components. The Competition model sits seven millimetres lower. 

There’s a broader range of standard driver assistance technology, too. Buyers get lane- keeping assist, lane-change assist, a 360-degree parking camera, and BMW’s Parking Assistant Plus, which can take control of the car’s steering when reversing into spaces. BMW also now offers a Drive Recorder function, which uses the car’s built-in cameras to record footage from around the vehicle.

So how does the AMG respond? Basically, by following the same plot. 

The revamped styling also includes a larger grille created in an effort to differentiate it more from the wider E-Class range and aerodynamic tweaks to optimise both grip and airflow to the engine.

Although the powertrains’ outputs are unchanged, Mercedes-AMG says considerable tuning has been carried out to widen the E63’s performance window. Work has also been done to refine the dampers and chassis, while the dynamic engine mounts on the E63 S have been tweaked so they adapt more quickly to driving conditions.

 Further development has been carried out on the AMG Dynamic Select software, which adjusts systems such as the drive programmes, all-wheel drive systems and ESP stability control. The AMG Dynamics Plus package, which includes a Race drive mode and Drift function, is standard on the E63 S and is offered as an option for the base model for the first time.

The front bodywork of the machine has been honed for aerodynamic balance, with AMG engineers and aerodynamicists focused on reducing wind resistance and increasing high-speed stability. The wheel arches have been enlarged by 22mm to accommodate a wider track

At the rear, there are flatter brake lights, a reshaped apron, which has also been aerodynamically optimised and a new diffuser.

The standard E63 has new 19in alloy wheel options, while the S version that’s always been favoured for NZ gains new 20 inch aerodynamically optimised five-spoke alloy designs. 

There are new paint colour options previously offered on the Mercedes-AMG GT range only and the usual optional AMG Night Package adds extra styling tweaks, including a gloss black finish for the mirrors, window frame and exhaust pipes. 

Inside, the E63 feature similar tweaks to the rest of the facelifted E-Class range, including the latest version of the MBUX infotainment system and digital instrument display, both of which offer bespoke AMG display options. 

There is also a new twin-spoke AMG Performance steering wheel with haptic feedback controls and offered with Dinamica microfibre or leather, or combination finish. The wheel includes a ‘hands on’ sensor that will trigger warnings and, eventually, activate emergency brake assist if it detects the driver does not have their hands on the wheel for an extended period. Mated to the new wheel are larger aluminium paddle shifters that can operate the nine-speed transmission.

M monsters set to roam post-virus

Even with the car market turning tough, there’s expectation the baddest editions of BMW’s X5 and X6 will do well.

TWO bigfoot BMW M models whose hugely potent engine is already defying the downsizing trend are strong enough to beat off Covid-19.

 That sentiment about the X5 M and X6 M is aired by BMW Group New Zealand as it opens the order book for the updated editions of the juggernaut sports activity vehicles, which share the same mighty twin-turbo V8 engine.

BMW Group New Zealand has stuck to tradition by deciding only the best will do for its customers.

Thus it is only bringing in the Competition, which in return for being the most expensive of the two specifications is also – with 460kW and 750Nm - the most powerful and best-kitted.

With the country gripped by a national shutdown of undetermined duration and also bracing for a severe economic impact, will the buyer base still have the discretionary spend to afford models that respectively price at $219,900 and $225,600?

BMW Group New Zealand managing director Karol Abrasowicz-Madej says it’s a fair question, but he’s optimistic the big stompers don’t become showroom queens.

In part, it’s because the M brand following is incredibly strong here. “We have a lot of loyal customers and we have a lot of interest coming from them.”

Also, there’s clear recognition that the models are pretty much without rival in their category. “They are very extrovert in their character.” So, even in this time of national inaction, there’s been plenty of “good inquiry” coming from owners of competitor cars.

So while it’s all a matter of wait and see until the lockdown lifts and business can resume, “we think they will find a place in Kiwis’ hearts.”

“I’m hopeful of a good take-up though, at the same time, any prediction at the moment about volume is going to be really hard.”

So they’ll survive, and so will the engine that also slots into the also NZ-available M5 sedan and M8 coupe and, in the sport activity vehicle application, lends ability to hit 100kmh in a claimed 3.8 seconds, 0.4 sec quicker than their forebears, aided by an extra 37kW of thrust.

Is this the final swansong for the V8? As much as BMW recognises that it’s becoming every challenging to maintain this kind of engine in the face of ever-tightening environmental regulations, in Europe especially, it says there’s still a good case for having it.

While acknowledging that various emissions rules are making his life more difficult, the head of powertrain project management for the X5M and X6M, Axel Theiling, reminds his team’s opus is far from being an old-school donk.

Built around a 90-degree vee angle and a sleeveless closed-deck crankcase, the 4.4-litre motor is a very sophisticated motor, with Valvetronic variable valve lift and direct fuel injection, as well as a pair of high-flow twin-scroll turbochargers.

Those ingredients allow for some reasonable emissions and economy. For a V8.

Still, make no bones: It is an engine designed foremost for performance rather than eco purity. Hence the forged crankshaft and a lubrication system built to cope with the rigours of track use. Also why the eight-speed automatic has manual modes and the M sport exhaust features four outlets so you can hear what the V8 has to say.

Other highlights include Adaptive M Suspension Professional with various modes, M Servotronic steering with Comfort and Sport settings, a rear-biased 4wd system, Active locking M differential and M Sport brakes with six-piston calipers acting on 395mm drilled and vented discs up front. A 100-0kmh emergency stop of 32 metres is claimed.

The M-spec X models stand out from the mainstream editions through adopting extrovert design features such as enlarged air intakes and an oversized wheel and tyre package (295/35R21s up front and 315/30R22s rear). They also have laser lights.

The cabin includes M multifunction powered and heated sport seats finished in full leather ‘Merino’ and Alcantara headlining, along with four-zone air con and head-up display. A panoramic sunroof, wireless charging and Apple CarPlay are included.

Safety and convenience items include BMW Driving Assistant Professional, Parking Assistant Plus and BMW Live Cockpit Professional with a pair of 12.3-inch LCD colour displays.

Deliveries are set to begin next month.
