SUSTAINABLE DEVELOPMENT
PERFORMANCE
Internal analyses conducted by Renault in 2007 based on the 27-member EU
indicate that 866,752 vehicles sold emit 140 grams or less of CO 2 per km,
with 37% of them emitting 120 grams or less of CO 2 per km.
In 1998, carmakers made a commitment to the European Commission to bring
average emissions down to 140 g of CO 2 /km for all cars on the road, i.e. 25%
lower than in 1995. The rating varies with the breakdown of sales. Negotiations
are in progress to reach a new target of 130 g of CO 2 /km by 2012.
This CO 2 emissions indicator is called CAFE (Corporate Average Fuel Economy)
for Europe. Renault’s CAFE indicator decreased slightly in 2006, placing Renault
once again among the top three European carmakers.
Renault used three methods to achieve these results.
Method 1, which concerns all projects, involves optimizing all the vehicle
parameters that have an effect on fuel consumption and CO 2 emissions:

for the vehicle: careful management of vehicle weight, lower aerodynamic
drag and road noise, and lower consumption by accessories such as power
steering and climate control in order to manage electrical energy more
effi ciently. For New Laguna, vehicle weight was cut by up to 65 kg for the
1.5 dCi version and aerodynamics were improved with a Cd of 0.293,
compared with 0.310 previously, for CO 2 emissions of 130 g per km;
for the engine: greater effi ciency and less friction, increased use of multivalve
technology, smaller turbochargers on diesel and gasoline engines, a sixth
gear added to many manual gearboxes, introduction of fi ve- and six-speed
automatic transmissions and Continuously Variable Transmission (CVT).
The 100 hp TCE (Turbo Control Effi ciency) engine combines drivability and
low fuel consumption. This new gasoline powerplant combines the power
of a 1.4 l engine (100 hp) with the torque of a 1.6 l engine (145 Nm) and
the low consumption of a 1.2 l engine (5.9 l/100 km over a combined
cycle). Vehicles in the I range equipped with this engine emit just 140g of
CO 2 over a combined cycle as the result of downsizing.
Despite the greater vehicle weight related to safety features and the increased
power for enhanced comfort, engine capacity and CO 2 emissions decreased
sharply between 1995 and 2006:

The six-speed gearbox on some Renault models significantly reduces
consumption for highway driving e.g. a decrease of 0.2 to 0.3 liters/100 km
in the I segment. The new Trafi c and Master were launched with a new, sixspeed
automatic transmission that improves fuel consumption by 0.5 to
1.0 liters/100 km for city driving.
Method 2 is the cross-functional deployment, led by the Vice-President of
Strategic Environmental Planning, of the “120 – 140 g objective” under Renault
Commitment 2009. At-end 2007, more than 150 versions of production
vehicles had dropped below the 140 gram threshold, of which one-third
below the 120 gram threshold.
To reach the sales target of one million vehicles in 2008, the European sales
network has introduced Renault eco 2 , an eco-label based on a number of criteria
that enable customers to easily identify Renault vehicles emitting less than
140 grams of CO 2 . The label thus reinforces the offi cial CO 2 labeling stating
the approved values for the vehicle on sale.
New Twingo expands the range of Renault vehicles emitting less than
120 grams, particularly the Twingo 1.5 dCi Renault eco 2 , which emits just
113 g of CO 2 / km. New Laguna demonstrates Renault’s expertise in downsizing.
The 110 hp 1.5 dCi version emitting 130 grams of CO 2 per km is the fi rst
vehicle in its segment to join the Renault eco 2 club.
Method 3 is to continue to bring vehicles running on alternative fuels to market.
After LPG, new fuels are being launched in the range in accordance with the
specifi c features of each region, the available infrastructure for the distribution
of each type of fuel, and customers’ habits.
Alternative energies ✦
Biofuels
On February 9, 2006 Renault announced that it would progressively bring two
types of biofuel vehicles to the European market over the period to 2009:
50% of gasoline-powered vehicles will be able to run on a mixture of gasoline
and ethanol, up to a maximum content of 85% ethanol;
100% of diesel-powered vehicles will be able to run on a mixture of diesel
fuel and biodiesel (up to a maximum of 30%).
These vehicles will join those already on sale in Brazil and pave the way for
the emergence of these two new energies elsewhere in the world, pending the
arrival of second-generation biofuels by 2015. Ranking among the synthetic
fuels most favorable for the environment, these fuels are promoted by the
Association for Synthetic Fuels in Europe (ASFE), a group whose founding
members are Daimler, Renault, Royal Dutch Shell, Sasol Chevron and the
Volkswagen group.
In June 2007 Renault launched France’s fi rst fl ex-fuel vehicle (able to run on
gasoline or a gasoline blend of up to 85% ethanol): the 110 hp Mégane 1.6
16v 100 hp E85. The fi rst customers are France and Sweden for the Mégane
hatch and sport tourer. The Group plans to continue development studies in
the passenger and commercial vehicle range.
At year-end 2006 Trafi c went on sale with the 84 hp and 90 hp 2.0 dCi B30 Euro
4 engines and Master with the 100 hp and 120 hp 2.5 dCi B30 Euro 4 engines.
For company fl eets equipped with B30 pumps and tanks, these vehicles can
run on B30 biodiesel. Deployment continued in 2007 with other diesel engines
in the Renault range. In 2008 a number of passenger cars could be equipped
with these engines, depending on the real demand from captive fl eets.
