Only Boost Pressure Separates The Panamera GTS And Panamera Turbo Engines

The 4.0-litre twin-turbo engine in the Porsche Panamera GTS is identical to the one found in the Turbo, but remapping it to Turbo power levels may not be advisable…
Only Boost Pressure Separates The Panamera GTS And Panamera Turbo Engines

By now, we usually know what to expect from GTS versions of Porsches. The formula has been repeated time and time again: the German firm takes an ’S’ model, turns up the power ever so slightly, lightly tweaks the chassis, make some normally-optional items (like ‘PASM’ adaptive dampers) standard equipment, and then finishes the car off with a sprinkling of sporty-looking black trim pieces. And a royal festooning of GTS badges, of course.

Imagine our surprise, then, when Porsche revealed the new Panamera GTS, complete not with a slightly more powerful version of the V6 used in the 4S, but a twin-turbo V8.

Our original suspicion that the 4.0-litre unit is derived from the Audi joint-developed unit found in the Panamera Turbo turned out to be almost correct. Speaking to Car Throttle at the launch of the new GTS in Bahrain, Panamera powertrain director Arno Bögl confirmed that the engine in the car is in fact mechanically identical to the Turbo’s V8.

Porsche merely turned the boost pressure down on the Panamera Turbo's 4.0-litre V8 before installing the engine in the GTS

Even the two twin-scroll turbochargers are the same; Porsche has merely turned down the boost pressure from 1.3 to 0.8 bar, in the process dropping the power from 542bhp to 454, and the torque from 568lb ft to 457lb ft.

Presumably, it would be possible to have a remap done to turn up the pressure, but that might not be advisable. While the engine is the same - save for the map and a new resonator intended to pass more noise into the cabin - the transmission is different. The higher-rated version of the PDK automatic gearbox fitted in the Turbo and Turbo S E-Hybrid Panameras simply isn’t necessary due to the lower torque figure, so Porsche has opted for one lower in the PDK pecking order.

But why use a V8 in the first place, when the tried-and-tested GTS formula would involve using the V6 from the 4S? That’s simple. “We decided to use the V8 because the V8 is the more emotional engine, you’ll hear the sound when you drive the car,” Bögl explained, adding, “The second reason is we can have a lot more torque [than if the V6 was used” - 100Nm more”.

“The V8 is the better engine for the GTS,” he concluded. We’ll tell you whether or not we agree when the driving impressions embargo drops mid next week.



I’m sure the tuners will not only be able to increase boost pressure but also do a TCU upgrade to the gearbox to compensate for the power

At which point the cost of the modification (especially once you consider the money lost on warranty etc) will be close to the difference between the gts and the turbo…

This make me think that Porsche is making disgusting margins on Turbo if youre getting the same hardware for a whole lot less in the GTS

Gearbox isn’t that cheap

Porsche makes the most profit per car in the whole industry, followed by Ferrari

But then it is still worth it

Actually I’m pleased to see a modern V8 with less than 500hp

Currently V8’s (at least if you’re buying a German car) seem to be reserved for 600+hp monsters - if a manufacturer wants to make a 450ish hp car they usually use a very turbocharged 6-cylinder engine (as the article suggested)

However seeing a V8 with so “little” power (compared to what it’s capable) gives a hope that the engine will be more responsive and generally feel more like a naturally aspirated one (which is better suited for a GTS-branded product)

So yeah I can totally see reason and value in that and would prefer it over the Turbo

Can’t wait for CT’s review!

Do you know the brand called „BMW“? They have the M550i and 750i with a sub 500hp V8.

I would totally have a GTS and remap the boost pressure up to Turbo level than having just a Turbo model.

I have something to report about this new GTS model after driving and riding in my for a couple days. The in dash digital boost guage shows 20PSI (1.4bar) when going full throttle. What is that about. It is a riot to drive because of the sound. And 3.1 second 0-60. Launch control is nuts
