Porsche Panamera vs Bentley Flying Spur

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 are two schools of thought when it comes to plug-in hybrids like the Flying Spur. Some people believe they provide the best of both worlds, combining elements of an EV and ICE vehicle. Others believe it’s a compromise, which requires you to carry around an electric motor and batteries you may not use much of the time.

The truth is the value of a PHEV will largely depend on how you use it. If you have a short commute and access to regular charging then it should work well for your needs, but if you need to drive longer distances and won’t charge it regularly it doesn’t make sense.

What isn’t up for debate, though, is how luxurious and premium the Flying Spur is. Sure, there are some surprisingly non-standard items that require you to spend above and beyond the already sizeable asking price, but if you do you’ll be rewarded with a car that is opulent and efficient.

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. 

Bentley isn’t exactly targeting a youthful audience with this car so there’s a, shall we say, traditional design aesthetic to the Flying Spur. This is a car that’s meant to ooze sophistication and luxury and it does that with its appearance.

From the signature Bentley grille, glistening in shiny chrome, to the intricate, jewel-like detail of the headlights, through the carefully sculpted flanks and to the tapered tail the Flying Spur is all about old-school luxury.

But there are some nice modern touches, highlighted by the ‘Flying B’ bonnet mascot, which not only can retract for improved safety, but at night it illuminates when you unlock the car, lending that touch of luxury that tells you that this is a step above most rivals.

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.

Not surprisingly, there’s generous room inside this modern limousine. The Flying Spur is one of those cars you’d enjoy being driven in, arguably even more than driving.

But before we talk about the back seat accommodations, let’s start in the driver’s seat.

The front of the cabin is another display of traditional luxury with a blend of modern technology. There is a veritable smorgasbord of premium materials - fine leather, bright metals and genuine wood veneers. 

The steering wheel is thick and wrapped in very nice leather so it feels great, as does the supple hide that covers the soft but supportive seat.

In front of the driver is a digital dashboard but the graphics are traditional round dials for the speedo and tacho, with a central area for other key information, such as the use of the hybrid system.

For the trained eye there are some giveaways that Bentley is part of the Volkswagen Group, the way some of the graphics are presented, some of the switchgear and other small elements - but nothing overt.

Space in the rear is very good, with more-than-adequate head, knee and legroom, but it’s not expansive as you’ll find in an extended-wheelbase vehicle, like its Bentayga SUV sibling.

Still, those in the rear are well looked after, elevating the Flying Spur beyond what you’ll typically find in a ‘luxury car’ - like those from the ‘big three’ German brands.

There are pillow-like headrests, for example, as well as plenty more premium materials and leather-lined surfaces.

But, again, a lot of the items fitted to our test car were cost options, such as the panoramic sunroof, rear window sun blinds and vanity mirrors that flip down from the ceiling.

Boot space is another surprising element of the Flying Spur, because despite the overall size of the car, it measures just 351 litres. For comparison, the Toyota Corolla sedan has a 470-litre boot.

It’s oddly shaped too, with space lost to the wheel arches and other hidden hardware, with even more room given up for the large charging cable bag.

In a sign of the times, the Flying Spur is the sole remaining four-door sedan in the Bentley line-up, as it now focuses on the Continental GT coupe and convertible and the Bentayga SUV.

While it may be the ‘old-fashioned’ member of the range, it’s probably the one that suits… shall we say… ‘traditional’ Bentley customers.

A four-door sedan is certainly not a ‘young person's’ car, but it clearly has a place and serves a role for the brand.

The Flying Spur range begins at $445,200 for the V8-powered model or $456,000 for the Hybrid (both prices exclude on-road costs). Although, as with any luxury vehicle, the starting price is just that, a starting point before you add your personalisation options.

In the case of our test car, pictured, it ended up at $589,641, with that extra $133,641 coming with a range of additional extras that, to be blunt, are surprisingly not standard.

For example, an inductive smartphone charging pad is a cost option, remarkable for a car of this price, when you consider it’s standard on low- and mid-grade Hyundai and Kia models.

The optional 'Mulliner Driving Specification' adds 22-inch 10-spoke alloy wheels, diamond quilted leather seats, sports pedals and more, but the Touring Specification includes active lane-keeping assist - all items that you could reasonably expect to be included on your $400K luxury car.

What is standard are the full LED matrix headlights, 20-inch alloy wheels and a 12.3-inch central touchscreen that incorporates navigation, Bluetooth and WiFi streaming, smartphone connectivity and even includes a CD/DVD slot. 

The standard sound system is a 650W, 10-speaker set-up, but you can option a Bang & Olufsen 1500W, 16-speaker system or even a 2200W, 19-speaker Naim option.

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.

This is obviously the centrepiece of the Flying Spur Hybrid and under the bonnet you’ll find a 2.9-litre twin-turbocharged V6 petrol engine paired with an electric motor and 18kWh lithium-ion battery.

The petrol engine makes 306kW/550Nm on its own, with the electric motor good for 100kW/400Nm and combined Bentley claims the powertrain produces 400kW/750Nm.

That power is sent to all four wheels via an eight-speed dual-clutch auto transmission.

Bentley claims the Flying Spur Hybrid is quick, as well as efficient, sprinting from 0-100km/h in just 4.3 seconds, with top speed rated at 285km/h.

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.

Fuel consumption and electric driving range are always tricky to judge with plug-in hybrids. The official testing cycle favours the combination of electric and petrol power resulting in an official combined cycle figure that’s difficult to hit in the real world.

As was the case with the Flying Spur Hybrid, which has claimed figures of 3.3L/100km, but we could only reach 6.5L/100km during our time in the car.

To be fair, less than 7.0L/100km for such a big, heavy and powerful car is still an impressive return, but it’s well short of the claim.

In terms of electric-only range and the energy consumption of the battery, Bentley claims an EV driving range of 40km, which we also found hard to manage during our test drive. 

The claimed energy use of 9.2kWh/100km is optimistic, though, with the car’s computer telling us it was actually 22.3kWh/100km.

Overall, Bentley claims the Flying Spur Hybrid has a maximum driving range of 804km thanks to the combination of electric and petrol power. 

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.

Climbing aboard and closing the heavy door with a thud, the Flying Spur feels isolated from the outside world before you’ve even turned the powertrain on. It adds that feeling of luxury and refinements that few other cars - and certainly few sedans - can claim these days.

Before you start driving you can select which version of the powertrain you’d like to use, with the ability to switch to all-electric power, a combination of petrol and electric or biased towards petrol to charge the battery.

In hybrid mode the Flying Spur manages which element of the powertrain it uses, typically using the electric motor to get you off the mark and boost performance on the move but allowing the petrol engine to do most of the heavy lifting.

Regardless of the details, it certainly provides the performance you expect from a car like a Bentley. It has the kind of effortless performance that means, despite its size, it never labours or struggles to close a gap or burst forward with urgency.

However, it’s electric mode that seems to fit the nature of the Bentley best - quiet, refined and powerful. Which makes sense.

Electric motors are so well suited to luxury cars that it's no surprise Bentley has committed to going all-electric by the end of the decade.

It’s a shame, then, that the 40km of range runs out quicker than expected and leaves you leaning on the petrol engine again.

The standard list of safety features includes front, side and curtain airbags as well as city assist (low-speed autonomous emergency braking), pedestrian warning, reverse cross-traffic warning and top view parking camera.

However, you’ll need to pay extra for the 'Touring Specification' pack that brings active lane assist, night vision and 'Bentley Safeguard Plus' (which adds high-speed autonomous emergency braking and pre-collision mitigation).

It’s shocking that nearly $500,000 doesn’t get you a comprehensive suite of active safety features and it hurts the appeal of the Flying Spur in some regard.

The Flying Spur hasn’t been crash tested by ANCAP, likely due to the high cost of the car and the relatively low sales volumes. 

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.

Another surprising element of the Bentley ownership experience is the relatively short warranty, at least by modern standards.

Like every other model in the range, it’s only covered for three years (but unlimited kilometres), which is short of the five years most other brands offer, and curious given the high standard to which these cars are built. 

However, the Flying Spur Hybrid is covered by a five-year servicing plan - with 12 months/16,000km intervals - which is included in the cost of the car.

Befitting Bentley’s status as a premium brand, the local dealer will arrange to collect and return the car when servicing is required, and a loan car can be arranged if required so the owner isn’t inconvenienced.
