As confirmed early last month, this latest change to the recently facelifted range brings a switch to Peugeot’s smaller and more efficient 2.0-litre turbo diesel engine, down in size from the outgoing model’s 2.2-litre unit.
The 508 GT models are now also more affordable at $59,990 for the sedan and $62,990 for the Touring wagon, amounting to around $3000 in savings.
In switching to the 2.0 litre engine, the 508 GT models have upgraded emissions compliance from Euro 5 to Euro 6, cutting CO2 emissions from 140 to 114g/km.
“The 508 GT signals a shift to Euro 6 engines across as many of our vehicle lines as quickly as possible, with the 208 range the next beneficiary of Euro 6 powerplants,” Peugeot Australia general manager, John Startari, said.
The change has also brought significant fuel consumption savings, with combined-cycle figures dropping from 5.3 and 5.5L/100km in the outgoing sedan and wagon, to 4.4 and 4.6L/100km in the 2016 models.
Peugeot says that this improvement could, depending on driving style and conditions, deliver a driving range of 1636 kilometres for the sedan and 1565kmfor the wagon - up from around 1200km in the current models.
But, while emissions and fuel consumption are down, the move to a smaller engine has also brought lower power and torque figures.
In their current forms, the 508 GT sedan and wagon models offer 150kW and 450Nm of torque, while the new engine offers 133kW and 400Nm.
This means the 508 GT is also slower to 100km/h, climbing from 8.2 to 8.6 seconds in both models.
Peugeot Australia is not expecting the drop in power to deter buyers, however.
Speaking with CarAdvice in August, Peugeot Australia communications manager Tyson Bowen said that 508 GT buyers aren’t drawn specifically to power.
“The change in 0-100km/h will be basically imperceivable, it’s a small change. Most of the people that purchase the [508 GT] cars do so for the ‘long-legged’ touring abilities of the car,” he said.
“Yes they steer better, but what it will also give them is a longer effective range as well. The change in its fuel use, if anything, it will probably increase interest in the model.”
“We’re still one of the only touring [wagon] models out there with quite a significant towing capacity and, again, this change will make that car more ‘long-legged’ in terms of its ability to eat up the miles,” he added.
For most buyers, Bowen believes, those factors will far outweigh the reduced power and acceleration numbers.
To that end, the 508 GT’s braked towing capacity has also increased slightly, up from 1800 to a new 1875kg.
Features and equipment for the updated 508 GT remain unchanged from the upgrade that hit Australia in May. Read about that here.
