Volvo will be unveiling its new sub-120g/km diesel variants of the C30 SportsCoupe, S40 saloon and V50 Sportswagon at the Paris Motor Show in early October. All three models are equipped with a special set of efficiency-enhancing features and marked with the DRIVe emblem to signal their uprated environment properties. Production of these new models will start in mid-November with first UK customer deliveries in January.
The new 1.6D DRIVe models will offer fuel consumption of 64.2mpg on the C30 and 62.8mpg in the S40 and V50, with VED Band B CO2 figures of just 115g/km for the C30 and 118g/km for the S40 and V50. Volvo claims that these new low emissions mean that the Volvo C30 and V50 offer best-in-class CO2 in their segments.
“We wanted to demonstrate that low CO2 ratings are not solely the preserve of small diesel cars. By offering the Volvo V50 with emission levels below 120g/km, we are also making it possible for families and other customers who require extra space to make an active pro-environmental choice,” says Volvo Cars President and CEO Fredrik Arp.
Volvo has made improvements in four areas:
1. Reduced air resistance:
• Chassis height reduced by approximately 10mm to help reduce drag
• A front spoiler on the S40 and V50.
• Covered radiator grille with a wind-deflecting panel behind that provides better aerodynamics inside the engine compartment.
• Wind deflectors in front of the front wheels to steer the airflow.
• Aerodynamically optimised wheels responsible for a total drag reduction of 10-15%.
• Underbody panels on the Volvo C30 for more efficient airflow under the car.
• A unique rear spoiler has been developed for the Volvo C30.
• New rear bumper on the Volvo C30.
2. Lower rolling resistance:
• All the cars are equipped with a new generation of Michelin tyres with low rolling resistance.
3. Higher ratios:
• Gearbox with altered ratios for third, fourth and fifth gears. The longer gear ratios contribute to a 1.5% reduction in fuel consumption without affecting the drivability of the car.
4. More efficient driveline:
• Optimised engine cooling, engine management and power steering.
• New transmission oil which creates much lower friction will be used in the gearbox.
• Gearchange indicator in the information display to tell the driver the ideal time to change gears.
“Changing the transmission oil gives us a 0.75 percent lower fuel consumption. Tyres with low rolling resistance save another 2 percent. Each of these measures may seem rather modest, but it is important to look at the whole picture. Taken together, all the small adjustments have helped us achieve our aim, with emissions below 120g/km for all three cars, without in any way compromising on either driving properties or comfort, which was an important requirement,” says Magnus Jonsson, Senior Vice President, Research & Development at Volvo Cars.
All new diesel models from Volvo are also fitted with a maintenance-free particle filter that traps about 95 percent of all soot particles.
The price supplement for the DRIVe package is estimated at between 150 and 450 euros depending on model and market. The DRIVe cars can be specified with most of the options and accessories that Volvo offer, apart from those that affect the cars’ aerodynamic properties. Prices, specifications and volume forecasts for the UK will be announced closer to the start of production.
