 Volvo Revises V70 and S80 Engines to Achieve CO2 Emissions Below 120 g/km
2010 Volvo V70

1.6 liter diesel engine features 109 hp and 240 Nm of torque with a 4.5 liters/100 km fuel economy rating

Volvo has done a little upgrading of its diesel offering for the V70 and S80 models with a new iteration of its 1.6 liter oil-burner power plant.

The 1.6 liter diesel engine, when coupled to a manual gearbox, can reach CO2 emission levels as low as 119g/km and a fuel consumption figure of around 4.5 liter/100 km. Volvo is seeking to reduce the emissions average of its entire fleet and with the addition of this new technology counts 5 models in its lineup that feature an emissions rating of less than 120g/km. These models are badged as DRIVe vehicles and also include the Volvo C30 (99g/km), Volvo S40 (104g/km) and Volvo V50 (104g/km).

Volvo has improved fuel efficiency on the engine through the use of "intelligent battery recharging," whereby the alternator only charges the battery when the engine is operating at a low capacity, such as going downhill. A second fuel-saving technology employed features friction reduction for the alternator and air conditioning compressor belts.

Power output on the V70 and S80 models with the 1.6 liter diesel and manual gearbox is 109 hp and 240 Nm of torque. Highway-driving economy for the engine is about 4.0 liters/100 km. In theory, that could drive a V70 or S80 for about 1750 km on a single tank of diesel fuel.

Volvo V70 and S80 - now with CO2 emissions below 120 g/km

The environmentally conscious Volvo customer can now buy a diesel-powered Volvo V70 or S80 with CO2 emissions as low as 119 g/km - corresponding to fuel consumption of just 4.5 l/100 km. This means that over the past year or so, Volvo Cars has succeeded in delivering five models with emissions below 120 g/km.

"There has been a swift pace of development since the launch of our first 119-gram models in Paris in autumn 2008. The fact that we have now brought two of the larger models in our range below the magical 120 gram limit shows that few of our competitors can match us when it comes to offering customers increasingly green cars," says Volvo Cars President and CEO Stephen Odell.

Volvo's DRIVe badge is found on cars with the best environmental performance in their respective size class. In addition to the Volvo V70 and S80, the other DRIVe models with emissions below 120 g/km consist of the Volvo C30 (99 g/km), Volvo S40 (104 g/km) and Volvo V50 (104 g/km).

As before, the new 119-gram versions of the Volvo V70 and S80 are equipped with a 1.6-litre diesel engine and manual gearbox. They have a power output of 109 hp and maximum torque is 240 Nm.

Intelligent battery recharging and less friction
Volvo's driveline experts have employed two techniques to reduce CO2 emissions from the previous 129 g/km (4.9 l/100 km) to 119 g/km (4.5 l/100 km):

  • Intelligent battery recharging, whereby the control system only allows the alternator to charge the battery when the engine is operating at low load, for instance when driving downhill.
  • Reduced friction for the belt that drives the alternator and air conditioning compressor. The redesign of the tensioner pulley and alternator pulley results in lower fuel consumption and lower emissions.

"Smart battery recharging is the most important measure. It is primarily thanks to this that we have dipped below the 120-gram level that gives car owners tax breaks and other benefits in a number of European countries. What is more, one might say that we offer the normal driver one free tank of fuel a year," says Ulf Nordström, Technical Project manager at Volvo Cars.

1750 km on one tank of fuel
The reduction in fuel consumption from 4.9 l/100 km (mixed driving cycle) to 4.5 l/100 km means that someone driving 15,000 km a year will save 60 litres of diesel. Translated into carbon dioxide emissions, the saving is 150 kg over a year.
"Since highway consumption is now just 4.0 litres per 100 kilometres, you can cover 1750 kilometres on a full tank of fuel. That's an amazing range bearing in mind the car's size," says Ulf Nordström.

It's amazing how low the fuel consumption is, taking into note that both the V70 and the S80 aren't exactly small or light vehicles.

Note that Volvo isn't bragging about the 0-60 time.

I'm not sure it even reaches 60mph, this is what makes a Volvo "safe". More seriously, a dual stage turbo would greatly help this car to move forward and compensate the small displacement.

only tiny little disadvantage is, that you will reach 100kmh in about 12-14 minutes. one thing is consumption measured on dynamometer, other is real driving conditions. and if you want to be faster than cyclists, you can forgot 4.5l S80 weight about 1.5 ton. and if you try to put in some family and luggage, it can be near two tons...

i dont think it is a good idea to put a 1.6 on cars such as s80's ..v70's (and maybe theyll put it on xc70 too). they are too large, and heavy. but above this, they are large ..pretty luxorious cars, right? so if you have the money to buy such a car, i see no reason to be cheap. imagine an a8 or s class with 1.6 turbodiesels. it's just wrong...

I'm surprised with this new for 2 big cars from VOLVO the V70 and the S80 with a little engine with 4 cilinder like this 1.6 liter engine with 109hp

Compare to the BMW 520d(F10) with 184hp and 5.0 liter/100km.. Huge difference in power but not in consumption.

Volvo makes his cars slower, nothing else.

I'm sorry... Come again, by using selective charging of the battery they've made this car do over 1000 miles on a tank. This is mocking the industry or at least the US vehicle market that can't get near these figures even with hybrid tech. Oh, and lets face it you'll be at 65mph or 100km/h for all of those 1750km for fear of a cop snatching your license, so top speed is pretty irrelevant.
