The homologated figures, revealed today, are even better than initial estimates: they initially put the XC90 T8 at 59g/km CO2, with less power than the final production car too.
Extensive development means Volvo can confirm 407hp, 472lb ft of torque and 0-62mph in 5.6 seconds from the 2.0-litre four-cylinder turbo engine and electric motor.
It also officially averages 134.5mpg, thanks to plug-in batteries that give up to 26 miles’ electric only range.
“We have been working hard to earn our competitive edge and to give our customers the ultimate combination of performance and low fuel consumption,” said Volvo’s senior VP for R&D Dr Peter Mertens.
“Our Twin Engine technology has enabled us to build on our heritage of efficient powertrain development in a completely new way… we (now) have a clear and leading position.”
Volvo hasn’t even had to strip seats out of the XC90 T8 Twin Engine – it still packs in up to seven people, thanks to the batteries being integrated into the chassis rather than added on at the back.
The big question is, of course, how muych the plug-in hybrid Volvo XC90 actually returns in the real world. Mitsubishi’s Outlander PHEV has been criticised this week by Which? for returning 120% less than its claimed fuel consumption during testing.
The next worst on the list? Volvo’s V60 Plug-in Hybrid, returning 92% less than Volvo claims…
