|Volvo’s 1.6D DRIVe models.|
At the upcoming Paris Motor Show in early October, Volvo Cars will introduce new diesel variants of the C30, S40 and V50 models with fuel consumption of 4.4 liters/100 km (53.5 mpg US) (C30) or 4.5 liters/100 km (52 mpg US) (S40 and V50). The corresponding CO2 figures of 115 and 118 g/km give the C30 and V50 best-in-class CO2 emissions in their segments. All three models are equipped with a special set of efficiency-enhancing features and marked with the DRIVe emblem to signal their uprated environmental properties.
The DRIVe models are based on the Volvo C30 Efficiency concept car that was shown at the Frankfurt motor show in October 2007. (Earlier post.) The measures adopted to reduce CO2 emissions that were presented then will be in production before the end of the year in the C30, S40 and the V50.
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 120 g CO2/km, we are also making it possible for families and other customers who require extra space to make an active pro-environmental choice.—Volvo Cars President and CEO Fredrik Arp
The cars were optimized within four distinct areas:
Reduced air resistance. Measures taken include lowering the chassis height by about 10 mm; using a front spoiler, as on the T5 (S40 and V50); a covered radiator grill with a wind-deflecting panel; wind deflectors in front of the front wheels; aerodynamically optimized wheels; underbody panels for more efficient airflow under the car (C30); a new rear spoiler for the C30; and a new rear bumper for the C30.
Lower rolling resistance. All the cars are equipped as standard with a new generation of Michelin tires with low rolling resistance. Available for 15 and 16 inch wheels.
Higher ratios. Gearbox with altered ratios for third, fourth and fifth gears.
More efficient driveline. Optimized engine cooling, engine management and power steering; new transmission oil with lower friction; and a gearchange indicator in the information display.
Changing the transmission oil gives us a 0.75 percent lower fuel consumption. Tires with low rolling resistance save another two 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 120 g/km for all three cars. Without in any way compromising on either driving properties or comfort, which was an important requirement.—Magnus Jonsson, Senior Vice President, Research & Development at Volvo Cars
Volvo’s DRIVe cars are all certified according to the mandatory European NEDC standard. In addition, the Volvo C30 has excelled in the ECO test, which carries out even more comprehensive measurements of CO2 and particulate emissions. This certification process relies on stars and points, in a similar way to the EuroNCAP programme for safety. The independent ECO test places the Volvo C30 at the top of its size category, with four stars and 76 points in the overall assessment of the car’s total environmental performance.
All new diesel models from Volvo are also fitted with a maintenance-free particle filter that traps about 95 percent of all soot particles.
Volvo will sell the DRIVe cars throughout Europe, and expects to sell more than 20,000 1.6D DRIVe cars next year. Sales are expected to spread fairly uniformly throughout the region, with France, Sweden and Spain accounting for most sales.
The price supplement for the DRIVe package is estimated at between €150 - 450 (US$212 - 635) depending on model and market. The DRIVe cars can be specified with most of the options and accessories that Volvo offers, apart from those that affect the cars’ aerodynamic properties.
