Mercedes-AMG GT vs Porsche 911: which to lease?

Updated September 2026 6 min read Performance & Prestige

The Mercedes-AMG GT we list is the GT 63 S E Performance — a four-door, four-seat plug-in hybrid with four-wheel drive and a hatchback boot. The Porsche 911 is a coupe. Both are partner-sourced and priced on request, so the real decision is whether you need doors or want a sports car.

The AMG GT we list is the four-door

Start here, because it decides everything else. When people say AMG GT they often picture the two-seat coupe with the long bonnet. The car in our catalogue is the Mercedes-AMG GT 63 S E Performance: four doors, four seats, four-wheel drive, a nine-speed AMG automatic, a plug-in hybrid powertrain and a hatchback boot.

That is not a lesser car — it is arguably the more useful one — but it is a different object from the sports car the name suggests, and finding that out at handover would be nobody's idea of a good start. It is arranged through a vetted partner, so it is quoted on request — as every car on the site is — and it carries no firm availability claim until the specific car is confirmed.

Which 911 is the fair comparison?

Two of the four we list. The 911 Turbo S is the closest in intent: four-wheel drive, a four-seat layout with small rear seats, and the ability to be quick in any weather. The 911 Carrera S is the rear-drive everyday version of the same idea and the most usable fast car in the catalogue.

The GT3 and GT3 RS are a different argument entirely — two-seat, rear-drive, track-derived cars that are not trying to do what the AMG does. If you are weighing those against a four-door saloon, the question you are actually asking is which kind of car you want, and our guide on the R8 Spyder against the 911 breaks the four Porsches down properly.

What four doors change over three months

More than most people expect. A rear door means somebody can get in the back without a negotiation, a child seat is a two-minute job rather than an argument, and colleagues can be collected without anybody having to fold themselves forward. The AMG's hatchback boot is the other half of that: it takes luggage the way an estate does rather than the way a coupe does.

The 911s with rear seats have them in the strict sense — they are genuinely useful for bags and for short journeys with people in them, and they are one reason the 911 has always been the usable supercar. But small is small. Over three months, if the car is doing family duty or carrying anybody regularly, the AMG's doors settle the argument without any further discussion.

Plug-in hybrid or petrol?

The GT 63 S E Performance is a plug-in hybrid, which is a practical consideration rather than an abstract one. If you have somewhere to charge it, you get the benefit of it; if you do not, you are carrying the hardware without the upside. That is worth deciding before the car arrives rather than afterwards, particularly on a three-month term where the habit either forms early or never.

All four 911s are conventional petrol cars, and one of them — the GT3 — is naturally aspirated, which is increasingly rare and is a large part of why people want it. If the character of the engine is a reason you are leasing at all, that pushes towards Porsche. If the car has to slip through a city quietly in the mornings, the AMG has an answer the 911s do not.

What does each one hold?

The GT 63 S E Performance holds a refundable £5,000 deposit against a £5,000 insurance excess, with mileage above the included 1,000 miles a month at £2.50 a mile.

On the Porsches, the Carrera S, the GT3 and the Turbo S also sit at £5,000 for both figures, so on money held the AMG and three of the four 911s are level. The GT3 RS is the exception at £10,000. Mileage is where they separate: £1.75 a mile on the Turbo S, £2 a mile on the Carrera S, £2.50 on the GT3 and £4 on the GT3 RS. If you expect to run over the allowance, the Turbo S is the cheapest of this group to do it in. All figures are provisional while the insurance arrangement is finalised and confirmed in writing before anything is agreed.

Do the driver criteria separate them?

Barely. The GT 63 S E Performance is set at a minimum age of thirty, with a full licence held for at least five years and no more than six points. The Carrera S, the Turbo S and the GT3 RS are set at the same. Only the GT3 differs, at twenty-eight.

So for most drivers, eligibility will not make this decision — which is unusual on this site, and it means the choice comes down to the thing it should come down to. Do you need a car with doors and a boot that happens to be very fast, or do you want a sports car that you will find excuses to drive? Nobody else can answer that, and a page that pretended otherwise would not be worth reading.

Doors, or a sports car?

Take the AMG GT 63 S E Performance if the car has to work as a car: passengers, luggage, a school run, a motorway on a Monday and a good road on a Sunday. It does all of that and is still an AMG when you want it to be, and it is the only one of these that will do the morning school run in near silence if you keep it charged.

Take a 911 if you want a sports car and you are prepared to work around it a little — the Turbo S for all-weather ability and the lowest mileage rate here, the Carrera S for the purer version. Every car on this page is partner-sourced, so send the dates, the delivery address and your licence details, and we confirm the car, the figure and your eligibility in writing before anything is agreed.

Common questions

Do you have the two-seat AMG GT coupe?

The AMG GT in the catalogue today is the GT 63 S E Performance, which is the four-door, four-seat car. If you want a two-seat Mercedes with a roof that opens, the AMG SL 63 is the roadster in the sourced catalogue, arranged through a partner and priced on request.

How many seats does the Porsche 911 have?

It depends which one. The Carrera S and the Turbo S have four seats, with a small rear pair. The GT3 and the GT3 RS are strict two-seaters. If rear seats matter at all, that narrows your 911 choice to two cars before anything else is considered.

Is the AMG GT four-wheel drive?

Yes, the GT 63 S E Performance is four-wheel drive, as is the 911 Turbo S. The Carrera S, the GT3 and the GT3 RS are rear-wheel drive. Over a British winter that is the single most useful difference on this page.

Can I lease either of these for three months?

Yes. Three months is the shortest agreement we write, on our own fleet and on the sourced catalogue alike. Every car named here is arranged through a vetted partner, so the monthly figure is quoted on request and confirmed with you before anything is committed.
