New plug-in petrol and electric hybrid powertrain and tougher diesel emissions standards will lower the manufacturer's diesel output
12 June 2016

Volvo's new three-cylinder T5 plug-in hybrid powertrain will significantly reduce the number of diesel cars it produces as it reacts to increasingly tough diesel emissions standards.

The new T5 hybrid system was shown in Gothenburg last month, alongside two 40-series concepts, and it will appear for the first time in the production XC40 next year

It uses a 74bhp electric motor that can power one of the shafts of a seven-speed dual-clutch automatic gearbox alongside a 180bhp turbocharged 1.5-litre three-pot petrol engine.

Electrical power comes from a 9.7kWh battery pack, which will give around 30 miles of electric-only range. According to Volvo’s head of R&D, Peter Mertens, the set-up is more efficient than rival hybrids and easier and cheaper to produce.

“It is a very attractive alternative to a diesel engine,” Volvo CEO Håkan Samuelsson said in Gothenburg. “It offers much lower CO2 levels but more or less the same performance in both horsepower and torque. On cost, I would say that within a couple of years, we will see a crossover, the diesel getting more expensive and the [hybrid system] going down.”

Volvo hasn’t released any emissions or economy data yet, but insiders indicate the T5 will manage substantially better than 95g/km on official tests and deliver diesel-rivalling economy in real-world use.

When asked if diesel cars will still be on sale in 10 years’ time, Samuelsson said: “Diesels will be more expensive. They will have much more advanced after-treatment, with additional fluids that have to be filled not once a year but probably every time you fill the car.

"It’s very realistic that the percentage will go down. If it will go down to zero, I think we don’t need to speculate; let customers decide. We are flexible enough that we can make petrol and diesel cars on the same line.”

The T5 system will be used in all the 40-series variants. Samuelsson said it is also likely to be offered in 60-series cars but not the largest 90-series models, where Volvo has a four-cylinder T8 that uses an electrically powered rear axle.

Our Verdict

Volvo V90

The Volvo V90 is less dynamically poised than some rivals, but it's still a deeply compelling machine

Oh, come on - never 'less diesel cars'!

13 June 2016
Shouldn't it be 'fewer diesel cars'as it refers to a plural noun?

12 June 2016
Those miles will be very cheap if one can plug the car overnight. Where there plugs on those concept cars?

9.7kW battery... 18 miles tops in real world.

Should be around 27. Electric running in a fairly heavy car typically gives a bit over 3 miles per kWh, and some of the battery capacity won't be usable.

"Less diesels"; good grief! It makes me chuckle that WhatCar? continue to castigate Lexus for "no diesels in range".
  • If you want to know about a car, read a forum dedicated to it; that's a real 'long term test' . No manufacturer's warranty, no fleet managers servicing deals, no journalist's name to oil the wheels...

In the winter with the above on will be even worse

12 June 2016
my current Q7 diesel can do the above journey on a tank, (85 litres)....750 miles if light on the throttle. What's a 3 cylinder engine's MPG on a motorway once the battery is drained after 18 miles, (maybe 30 if you believe the blurb)?

12 June 2016
I based my assumption on my PHEV which has a 12kW battery but only uses 10kW of it as you can't flatten an EV battery too far or you damage it, the car prevents this. Typical range is 25 miles or less. Assume the Volvo only can only use say 8kW of the battery and is around the same weight then I think 18 miles tops, probably a fair bit less.

13 June 2016
Volvo XC90 T8 PHEV have 9kWh and is rated 17 miles by EPA. (USA measure)

So smaller and more efficient body style should get better range 20-25 depending on how small drag coefficient they get.

PS in BEVs efficiency is very good, but that is by body style and torque&traction control & weight reduction. So big SUV like cars that do not make same effort won't replicate the efficiency.

    The Citroen C3 Aircross has got funky looks and a charming interior, but it's another small SUV, and another dynamic miss. Numb steering is just one thing keeping it from class best

    Diesel version of Skoda’s junior SUV is unobtrusive and undemanding, but we’d still go for the silkier petrol version of the Karoq
