Porsche Panamera vs BMW 5 Series

What's the difference?

While we didn’t get to sample the full breadth of the range, our time in the base Panamera demonstrated that while it’s the most overlooked member of the Porsche family it might also be the most under-rated.

While it may not be the most spacious luxury sedan it does offer ample space and combines it with performance and handling that’s hard to beat. The price drop should help make it a more appealing prospect, although at nearly $200,000 it’s still clearly a premium prospect for a lucky few.

There’s no getting around the i5 being a rather expensive offering. More than $150,000 to get into an electric sedan that’s not much faster than a hot hatch is a big ask, but there’s plenty to enjoy about the 5 Series.

Things like its heated leather seats shouldn’t be the reason you’re willing to spend so much on a sedan when a $50,000 hybrid SUV will score you the same, instead it’s the fact the 5 Series is a delight to drive and hasn’t lost the feeling of prestige the badge has earned over the last half a century.

In terms of value - if speed isn’t your focus and you’re less of a gadget-type-operator when looking at cars like this - the 520i has the style and comfort you’d need and at $100K less than the M60.

And in terms of large electric sedans, the i5 eDrive40 is cheaper than a Porsche Taycan (by a little) or an Audi e-Tron (by a lot). The Genesis G80 Electrified is the closest cheaper rival, by about $10K, or the less powerful Mercedes EQE is similarly priced at $154,900.

Essentially, if you’re looking at a 5 Series, it might be worth considering if you really need it to be electric, but if so, there aren’t many alternatives in its category for the price.

When the second generation Panamera arrived in 2017 it was widely praised for its design. The new model allowed Porsche’s stylists to tidy up the somewhat puffy design of the original whilst still retaining a clear family link to the 911.

For this mid-life update Porsche has only made some minor nip and tucks rather than a major facelift. The changes centre around the front end, where the 'Sport Design' package that was optional is now standard across the range. It has different air intakes and larger side cooling openings for a more dynamic look.

At the rear there’s a new light strip that runs across the boot lid to connect to the LED tail-lights, creating a more seamless appearance. 

The Turbo S also gets a unique front end treatment, to further separate it from the previous Turbo. It gets even larger side air intakes that are connected via a body-coloured horizontal element so it stands out from the rest of the range.

Overall it’s hard to fault Porsche’s decision to not meddle in the design too much. The shape of the Panamera, like a stretched 911 in silhouette, has grown on people over time and the changes they made for the second generation, making it tauter and more athletic in appearance, didn’t need change for the sake of change. 

If you’ve watched other members of the BMW family go into a new generation within the last few years - the 3, 4 and 7 Series particularly, you won’t be too surprised by what you see here. Especially with the latter, having seen the petrol variants look roughly the same as the electric ones.

BMW specifically made the petrol 520i and the i5 variants look similar for egalitarian purposes - to not disenfranchise 520i buyers who are still spending a fair chunk of cash but might not be ready to go EV.

That means all three variants score a mix of new and old. The kidney grille remains and isn’t as large as on the M3 or 4 Series, while the bonnet line following it and the ‘character line’ down the car’s side also remain. And yes, the Hoffmeister kink where the C-pillar meets the passenger window’s lower corner is still there.

On that C-pillar though is a ‘5’ stamped into the bodywork, new to this generation, while the front grille as mentioned has a glowing light surround - the brand’s ‘Iconic Glow’ already seen on the 7 Series.

Overall, thanks to being slightly larger in every dimension, the new 5 is starting to look bigger than a 7 Series from a little while ago. And that’s because it is - its body is overall longer than an E65 7 Series from the mid-2000s.

It’s 5060mm long 1900mm wide, 1515mm tall (97mm longer, 32mm wider, and 36mm taller). Its wheelbase is 20mm longer too at 2995mm. 

As the limousine of the Porsche family there’s a big emphasis on space and practicality for the Panamera. But there’s a big difference between a Porsche limo and the rest of the German ‘Big Three’, which is why the Panamera’s closest rivals are the sportier A7/8 Series/CLS and not the bigger A8/7 Series/S-Class. 

The Panamera isn’t small, stretching more than 5.0m in length, but because of its 911-inspired sloping roofline rear headroom is compromised. Adults under 180cm (5' 11") will be comfortable but anyone taller may find their heads bumping the roof.

The Panamera is available as both a four- and five-seater, but in a practical sense it would be hard to carry five. The rear middle seat is technically available with a seatbelt but heavily compromised by the rear air-vents and tray that sit on the transmission tunnel and effectively remove anywhere to put your legs.

On the plus side, the outboard rear seats are excellent sports buckets, so they offer great support when the driver exploits the Panamera’s sporty chassis.

This only applies to the standard wheelbase model, the Executive adds 150mm to its wheelbase which primarily helps create some more rear legroom. But we didn’t get a chance to test that for ourselves on this initial launch drive, so we can’t verify Porsche’s claims.

Those in the front get excellent sports seats across the range, offering lateral support whilst still being comfortable.

A longer wheelbase means more space inside, where the 5 Series also still looks fairly familiar to those who have spent any significant time in a recent model BMW.

BMW has historically been pretty bang-on with ergonomics, and the new-gen 5 does a good job of sticking to that. Comfortable sports seats and quality feel for the materials on touch points mean the 5 Series feels nice to be in, and relatively restrained interior design for a somewhat luxurious car means it looks nice too.

It’s let down only by a couple of things - its multimedia screen and Operating System 8.5 is a little less simple to use now, and requires more touching the screen than previous iDrive systems, rendering the scroll wheel less useful.

The BMW Interaction Bar too is a little tricky to see controls on, as well as lacking physical feedback for using controls. Vent flow controls are digital sliders on the Bar, while vent direction is controlled by an unusual ‘joystick’ style control nearby.

The rear seat is plenty spacious, as you’d expect from a large sedan, with climate controls and ports for charging devices in the rear.

There are three members of the new 5 Series family from launch, with a base 520i starting things off from $114,900 before on-road costs.

It’s the only petrol-powered (with mild-hybrid, we’ll come back to this) variant in the trio, but it does have a fairly extensive list of features as standard. In terms of tech and comfort, most of what comes with the 520i is available further up the range too, with the major differences being drivetrain related.

In the 520i, the interior upholstery is synthetic ‘Veganza’ leather with Alcantara, though optional Merino leather is a $4000 BMW Individual option. The front seats are heated as standard, however, and electrically adjustable with memory settings and lumbar support.

A 12.3-inch instrument display paired with a 14.9-inch multimedia display are standard across the range, running BMW’s Operating System 8.5, while a head-up display, ambient lighting, wireless phone charging tray and BMW’s ‘new’ Interaction Bar are included too - a crystalline-style strip across the dash with touch-sensitive ‘buttons’ like the climate controls.

A panoramic glass roof - unable to be opened - is standard too, while the 520i’s sound system is a Harman Kardon set-up with 12 speakers.

Exterior features are quite similar to the more expensive i5 variants, with Adaptive LED headlights, automatic boot opening, an M design kit with front and rear aprons, side sills, and BMW’s Iconic Glow kidney grille surround.

Optional in the 520i is an ‘Enhancement Package’ which adds a choice of aerodynamic 21- or 20-inch wheels, metallic paint, and a 655-watt 17-speaker Bowers & Wilkins surround sound system for $5400. One test car on the launch we attended was painted in a BMW Individual colour - Tanzanite Blue - which upped the price to $7800.

Moving up the range to the mid-tier i5 eDrive40, which starts from $155,900, adds Merino leather interior, metallic paint, Bowers & Wilkins surround sound and aerodynamic 20-inch wheels standard, but it also includes adaptive suspension and some other EV-related features.

BMW’s ‘Adaptive Suspension Professional’ comes with Integral Active Steering (rear-wheel steering) and is a step up over the M Sport suspension from the 520i, while its aero wheels function as a way to keep the electric car’s range being affected by resistance.

The eDrive40 also comes with an acoustic protection system to make ‘electric car noises’ to warn pedestrians, as well as BMW’s ‘Iconic Sounds’ for the occupants - basically a system that uses orchestral sounds composed by Hans Zimmer that are affected by acceleration intensity, speed, and drive mode.

It also comes with the standard kit for an electric car, a Mode 2 and Mode 3 charger, cable, and a five-year Chargefox subscription. 

The top-spec i5 M60 xDrive ups the cost to $215,900 and the features list again slightly (as well as being far more powerful).

Its suspension is even more advanced, adding the brand’s Adaptive M Suspension Professional with active anti-roll, plus 21-inch aero wheels as a no-cost option. The M60 also gains an M rear boot lip spoiler.

Inside, BMW’s ‘Crafted Clarity Glass’ controls in the centre console are standard, as is ventilation for the front seats and a four-zone automatic air conditioning system.

As mentioned earlier there’s a smorgasbord of powertrains for the Panamera range with a variety of V6 turbo, V8 turbo and hybrid variants of both to choose from.

The entry-level model, known simply as Panamera, gets the 2.9-litre twin-turbo V6 making 243kW/450Nm and paired to an eight-speed dual-clutch transmission and sending drive to the rear-wheels. 

Step up to the Panamera 4, 4 Executive and 4 Sport Turismo and you get the same engine and transmission but all-wheel drive.

The Panamera 4 E-Hybrid range (which includes Executive and Sport Turismo) has the same 2.9-litre twin-turbo V6 but adds a 100kW electric motor. 

That means a combined system output of 340kW/700Nm, driving through the same eight-speed dual-clutch and all-wheel drive system as the non-hybrid variants.

The Panamera 4S E-Hybrid gets an upgraded 17.9kWh battery, replacing the old model’s 14.1kWh version. It also gets a more powerful version of the 2.9-litre V6, tuned to make 324kW, which ups the total output to 412kW/750Nm; again with the eight-speed dual-clutch and all-wheel drive. 

The Panamera GTS uses the brand’s 4.0-litre twin-turbo V8 engine, tuned to make 353kW/620Nm, also with the eight-speed ‘box and all-wheel drive. 

The Turbo S uses the same engine but it gets a new tune to bump performance to 463kW/820Nm; that’s a 59kW/50Nm increase over the old model’s Turbo, hence Porsche’s justification in adding the ‘S’ to this new version.

And if that’s still not enough grunt, the Panamera Turbo S E-Hybrid adds the 100kW electric motor to the 4.0-litre V8 and the combination produces 515kW/870Nm.

Interestingly, despite the extra power and torque, the Turbo S E-Hybrid isn’t the fastest accelerating Panamera. The lighter Turbo S does the 0-100km/h sprint in 3.1 seconds, while the Hybrid takes 3.2 seconds. 

However, the 4S E-Hybrid does manage to out-accelerate the GTS despite using the V6 engine, taking just 3.7 seconds compared to the 3.9 seconds it takes the V8-powered GTS.

But even the entry-level Panamera still does a very rapid 5.6 second 0-100km/h dash, so none of the range can be called slow.

Despite BMW calling it ‘electrified’, the base 520i is only a mild hybrid so most wouldn’t realise unless they were told.

Its turbocharged 2.0-litre four cylinder puts out a modest 153kW and 330Nm, with power and torque sent to the rear wheels via an eight-speed automatic transmission.

BMW claims it’ll knock over the 0-100km/h sprint in 7.5 seconds, a few seconds too slow to blow anyone’s socks off.

The mid-spec eDrive40 has a little more kick to it, its rear-mounted electric motor capable of 250kW/430Nm and able to cut that time to 6.0 seconds.

It’s fitted with an 84kWh battery to draw its power from, the same as the 442kW/820Nm M60 with its all-wheel drive dual-motor setup.

The M-tuned i5 can hit 100km/h in a claimed 3.8 seconds. Bye bye socks, perhaps.

We didn’t get a chance to test all the variants and run the numbers against Porsche’s claims. Again, in an unsurprising development the hugely diverse range of powertrains leads to a wide spread of fuel economy numbers. 

The leader of the pack is the 4 E-Hybrid which uses just 2.6 litres per 100km, according to the company, just ahead of the 4S E-Hybrid with a 2.7L/100km claim. Despite all of its performance the Turbo S E-Hybrid still manages to return a claimed 3.2L/100km.

The entry-level Panamera we spent the majority of the time in uses a claimed 9.2L/100km. The Panamera GTS is the least-efficient, with a claimed 11.7L/100km return, which puts it ahead of the Turbo S and its 11.6L/100km figure.

BMW claims the petrol 520i sips 6.7 litres per 100km from its 60-litre fuel tank, though we were unable to independently test any of the claimed figures on the launch day.

The base car has a theoretical range of 896km if it was possible to achieve the claimed fuel consumption figure for the duration of the whole tank - but it isn’t and realistically you could knock about 20-30 per cent off that, depending on how enthusiastically you drive.

In the i5 variants, the same 84kWh battery provides slightly different ranges due to the eDrive40 using 16.56kWh per 100km, and the M60 using 18kWh.

The eDrive40 has a claimed 550km maximum range, while the M60 has a 506km figure thanks to its extra motor and weight.

This is where the Panamera really excels. With every vehicle it builds, Porsche works to make it drive as close to a sports car as possible, even if it's an SUV or, in this case, a large, luxury sedan.

Although Porsche has an extensive range, our test drive was primarily focused on the entry-level model. That’s no bad thing as it’s likely to be the biggest seller in the range, but also because it’s an excellent example of a sports sedan done well.

It may be the first rung on the ladder, but the Panamera doesn’t feel like it's basic or missing anything important. The engine is a gem, the chassis is well sorted and the standard equipment level of Australian models is higher than average.

The 2.9-litre V6 twin-turbo makes a nice noise, a melodious V6 burble, and delivers plenty of punch when needed. Even though it tips the scales at more than 1800kg the V6 with its 450Nm of torque helps punch it out of corners with intent.

The corners is where the Panamera really shines. Even by the highest sports sedan standards the Panamera is a class-leader thanks to all of Porsche’s decades of know-how being poured into its development.

Point the Panamera at a bend and the nose responds with the kind of precision you expect from a sports car. 

The steering provides accuracy and loads of feedback, so you can place the car accurately despite its size. 

You do notice its size and weight as you get into the middle of the corner, but that’s no different from any of its rivals as you can’t fight physics. But for a luxury sports sedan, the Panamera is a star.

To add another layer to its appeal, the Panamera rides with excellent poise and comfort despite its sporting nature. 

Often sports sedans tend to focus too much on handling and stiffer suspension settings at the expense of ride comfort, but Porsche has managed to strike a great balance between the two seemingly opposing characteristics.

For some cars, the list of features is what really separates the variants, but that’s not the case for the 5 Series. As is a bit of a BMW tradition, the drivetrains dictate the different trim levels and prices, and there are three fairly distinct flavours of 5 Series.

Starting at ground level, the 520i might at first seem like a bit of boring vanilla. Except it’s actually quite smooth and light vanilla.

There’s not a lot to write about when it comes to its drivetrain, but the lightness of its engine and petrol tank combo when compared to EV batteries and motors is refreshing, and makes for a quite dynamic rear-drive sedan.

Its 153kW and 330Nm is delivered smoothly enough with the mild hybrid assistance doing a little in helping responsiveness, but without intervening in the gearshifts it doesn’t feel particularly keen.

It lacks the ride comfort of the i5’s adaptive suspension, but it’s able to be driven in a spirited manner that belies its size and even, to some extent its 1725kg kerb weight. Chocolate sprinkles on the vanilla, if you like.

It’s not fast, but it feels nimble compared to its electric siblings and can carry a fair bit more speed through corners, after which there’s room to notice its rear-drive characteristics.

It’s especially noticeable after getting out of the 2130kg eDrive40, though the extra power from its 250kW/430Nm motor makes for some more spirited acceleration and a little more excitement when exiting a corner, especially if you’re aiming to double-check if it really is rear-wheel drive. There’s a little more than choc-topped vanilla going on here.

The steering is, like in the 520i, direct and responsive, though in most cases is probably best set to ‘comfort’ rather than ‘sport’ in its settings. 

The eDrive40 is rather comfortable and capable when barrelling through twisty backroads, and doesn’t feel out of hand for a five-metre-long sedan. It holds its weight well, and telegraphs when you might be approaching the limit quite sensibly.

When considering that, then, it’s impressive how brutally capable the 2305kg M60 is.

Here, we’re looking at a double-choc fudge with extra choc, and maybe some cookie dough in there for good measure. There’s a lot to like, but boy is it heavy.

It’s 580kg (or exactly half a Peugeot 208 GTi) heavier than the 520i, but it feels quick on its feet and its anti-roll seems to do a lot in terms of dynamics, the limiting factor really seems to be its tyres (which can and will squeal quite quickly to let you know when approaching said limit).

While you’ll need to take caution with how much speed you approach a corner with, you’re not going to lack acceleration on the other side, its all-wheel drive being less ‘fun’ but more efficient at getting you away from the bend than in the rear-drive eDrive40.

That adaptive suspension does also translate to a comfortable ride on relatively rough roads - only particularly bad bumps will reveal how much weight and pressure is being placed on each corner of the big sedan.

ANCAP hasn’t crash tested the new 5 Series. The last generation was a five-star car and it would be unusual to see that change with additional safety features - even with stricter testing.

The 5 Series comes with BMW Driving Assistant Professional as standard, with active cruise, lane assist and departure warning, front and rear cross traffic alert, collision prevention and intervention systems - in fact BMW says it has about 40 safety systems including an augmented reality dash display.

Its list of airbags includes front and side airbags for driver and passenger including one between the two occupants, as well as curtain airbags front and rear.

Service intervals are annually or every 15,000km (whichever comes first) for routine oil changes, with every second year a more significant inspection. 

Prices vary state-to-state due to different labour costs, but as an indication Victorian residents pay $695 for the annual oil change, while the inspection costs $995. 

There are other notable charges you should factor in, including brake fluid every two years for $270, while every four years you need to change spark plugs, transmission oil and air filters which add up to an extra $2129, on top of the $995.

The Panamera is covered by Porsche’s typical three-year warranty/unlimited kilometre, which used to be the industry standard but is increasingly becoming less typical.

BMW has a fairly industry-standard five-year/unlimited kilometre warranty on its new cars, while its electric car batteries are covered by an eight year/160,000km warranty.

For servicing, BMW offers numerous discounted packs and deals based on your preferences and desire to pay upfront.

For the 5 Series, a five-year/80,000km basic service package is $2400, though the i5 will have different needs and lower servicing costs not yet listed by the brand.
