Opel press release :
Rüsselsheim. The new Corsa range has been rejuvenated to provide
more power and more driving fun with less fuel consumption. Opel
engineers have given the Corsa a complete make-over, introducing an
enhanced powertrain line-up that reduces fuel consumption by up to 13
percent, significant chassis improvements and a new steering
calibration. In addition to its agile handling and greater ride
comfort, drivers will appreciate engines that give more pulling power.
These enhancements are accompanied by the introduction in Germany of
several new special editions like the sporty Color Line series. The
Color Race, Color Edition and Color Wave variants feature distinctive
bodywork finishes and attractive 17-inch alloy wheels. Also, in
celebration of 111 years of automotive tradition, Opel will release a
captivating 111 Limited Edition in Europe.
The Corsa comes in two distinct body styles, the coupé-like
three-door and the family friendly five-door. Inside the cabin, the
Corsa continues to offer one of the roomiest and most attractive
interiors in its class. True to Opel’s philosophy, it also features
innovative technologies at an affordable price, including halogen
Adaptive Forward Lighting (AFL), a heated steering wheel, active front
head restraints, Hill Start Assist, a Panorama sunroof or the
integrated FlexFix bicycle carrier which is unique to Opel.
The Corsa is a highly popular choice throughout Europe, accounting
for some 30 percent of all Opel/Vauxhall sales. In addition to its
athletic dynamic styling and great driving fun, it also offers
customers top class quality. Germany’s DEKRA Defect Report 2010 named
the Corsa the overall winner, with the lowest defect rate (2.4 percent)
of all the vehicles tested. DEKRA (Deutscher Kraftfahrzeug-Überwachungs-Verein) is a full-service provider for safe and efficient mobility and Europe’s leading technical expert organization.
Reinvigorated to deliver more driving satisfaction and lower fuel
costs, the Corsa range ticks all the right boxes for customers seeking
a peppy package at an affordable price.
More power with improved fuel economy
The powertrain line-up consists of a wide offer of gasoline engine
from the 1-liter 3 cylinder (48 kW/65 hp ) entry level version to the
turbo charged 1.6-liter on the Corsa OPC (141 kW/192 hp). On the diesel
side, different versions of the 1.3 and 1.7 CDTI motors offer outputs
ranging from 55 kW/75 hp to 96 kW/130 hp all with fuel consumption
under 5 liters per 100 kilometers. The Corsa ecoFLEX 1.3 l CDTI offers 
exceptionally low CO2 emissions of just 98 g/km for the 3-door variant,
99 g/km for the 5-door.
Opel engineers have developed the engines to give greater torque,
while at the same time reducing their appetite for fuel and lowering
CO2 emissions. All gasoline engines, and the new 1.7 CDTI diesel,
comply with Euro 5 emissions standards.
The most popular gasoline powertrains – 1.0, 1.2 and 1.4-liter with
manual and automated Easytronic transmissions – offer combined cycle
fuel consumption between just 5.0 and 5.5 l/100 km, and CO2 ratings
from 117 to 129 g/km with manual transmission. With an average fuel
consumption of just 5.0 l/100 km and 117 g/km CO2, the Corsa 1.0 is the
cleanest of all gasoline-powered entries in its segment. The 1.4 engine
comes in two variants, with 64 kW/87 hp and 74 kW/100 hp and is
available with full automatic transmission in its most powerful
execution. The 1.2 and 1.4-liter Twinport engines are now fitted with
double cam phasing to allow variable valve timing on both inlet and
exhaust sides for more efficient breathing.
Other measures that improve fuel consumption for all gasoline
engines include a low friction oil pump, remapping of the engine
thermostat and a ”shift up” indicator to help the driver change gear
for optimum fuel economy.
The 1.3 CDTI engine is also improved, giving the Corsa ecoFLEX model
exceptionally low CO2 emissions of just 98 g/km for the 3-door variant,
99 g/km for the 5-door. The Corsa ecoFLEX is Opel’s lowest emitting
car, yet it is packed with 27 percent more power and 10 percent greater
fuel efficiency. A diesel particulate filter and the “shift up”
indicator in the cluster are standard.
The top-of-the-line 1.7 CDTI diesel engine now offers more power and
torque – increased to 96 kW/130 hp and 300 Nm – as well as a nine
percent cut in CO2 emissions and fuel consumption, to 118 g/km and 4.5
Uprated chassis and steering
Opel chassis engineers have upgraded all major suspension components
and the steering system. The result is improved ride comfort, more
precise steering feel and greater directional stability – without
compromising Corsa’s acclaimed agility. 
Dampers, springs, anti-roll bars, the rear axle, the electric
steering gear and its calibration software all have been optimized. All
the changes apply to Essentia, Enjoy and Cosmo variants, while versions
equipped with the Sport chassis, GSi and ecoFLEX models benefit from
additional improvements to the rear axle and steering.  The Corsa OPC
took over the changes applied to the steering gear.
