   -   Five engines from launch, each meeting Euro 5 standards
   -   Petrol engines: turbo and naturally-aspirated units, four and six cylinder
   -   Diesel engines: new 2.0-litre units with maintenance-free particulate filters

The new Vauxhall Insignia launches with a range of five engines, all of which meet
Euro 5 emissions standards. The three petrol engines range from 140 to 260PS and
two new 2.0-litre turbo-diesels are available with either 130 or 160PS. All engines are
highly competitive in terms of CO2 and fuel consumption in their respective power
output categories. The powertrain range will be expanded in time with new, more
powerful engines. In addition, an ecoFLEX version with low CO2 emissions will join the
lineup.

Apart from the auto-only 260PS V6 model, each engine is mated to a six-speed manual
gearbox, with all but the 1.8-litre petrol model being available with the optional six-
speed automatic transmission. All-wheel-drive is standard on 260PS V6 models, and
optional on 2.0-litre turbocharged petrol cars.

Overview - Insignia petrol engine range

The 2.0-litre turbo is new in the Vauxhall mid-size class segment. The 220PS direct-
injection engine is of all-aluminum construction and generates 350Nm of torque from
2000 to 4000rpm, with twin balancer shafts to ensure smooth running. This engine also
illustrates the downsizing policy at GM as this 2.0-litre, four-cylinder model is
competitive with five- and six-cylinder cars in terms of performance, but has lower fuel
consumption and emissions.

The entry level petrol engine is the 1.8 ECOTEC (140PS) recently introduced on other
models in the Vauxhall range. The range-topping petrol engine is the 2.8-litre V6 Turbo,
which develops a generous 260PS and 350Nm of torque between 1900 and 4500rpm.

All petrol engines feature camshaft phasing – on both intake and outlet sides for the
four-cylinder units, and on the intake side for the V6. Variable valve timing increases
torque at low rpm and plays an important role in reducing fuel consumption as well as
meeting new Euro 5 emissions standards.

Overview - Insignia diesel engine range

The new-generation Vauxhall 2.0-litre diesel engines in the Insignia feature more power
and torque, as well as excellent fuel economy. The Insignia will launch with two
versions of the 2.0 CDTI engine developing either 130PS or 160PS. This last engine
variant will also power the Insignia ecoFLEX with lower fuel consumptions and CO2
emissions. All versions come with a maintenance-free diesel particulate filter as
standard and meet Euro 5 emission levels.
The engines have two overhead camshafts, four valves per cylinder, and common-rail,
multiple fuel direct injection, together with a variable geometry turbocharger for a rapid
throttle response from low rpm. Thanks to the large 70-litre tank, the diesel models
boast a range of approximately 750 miles, based on their combined fuel consumption
figures.
