Opel continues to improve and refine the company's flagship, Opel Insignia
, which has a huge success. Ready for 2012, Opel will offer diesel engines with a new and extremely efficient engine variant BiTurbo dynamic.
2-liter CDTI unit has an output of 143 kW/195 hp and generates 400 Nm of torque; four-door sedan with front traction and manual transmission consumes just 4.9 liters per 100 kilometers (and an emission level of 129 g of CO2/km). Therefore, the Insignia 2.0 CDTI BiTurbo is one of the most efficient midsize car in terms of fuel consumption.
Since spring 2012, all wheel drive variants can be ordered with SuperSport chassis including a front suspension Insignia OPC (Opel Performance Center) and HiPerStruts system that further increases driving dynamics. Moreover, active safety is enhanced by the Insignia support systems. The peak of the Opel, since its debut in 2008, Insignia has won about 50 national and international awards, including the prestigious Car of the Year Award 2009. Appreciation shown by experts is reflected in strong demand from customers: has managed sales of nearly half a million units. In 2011, Insignia has experienced strong growth rates in key markets (including Great Britain, Russia and Turkey).
In Germany, 5-door hatchback sedan is the undisputed leader of its segment in terms of sales. Opel also boasts the most economical petrol engine of the medium segment, the engine of the Insignia 1.4 Turbo 103kW/140 hp ecoFLEX (5.7 litres/100 km, 134 g / km CO2).
Latest technological advances are the continued success of the top model from Rüsselsheim.
Diesel BiTurbo technology. How it works!
Main element of the engine with four-cylinder common rail is the system with two turbochargers and two sequential stages of supercharging. To date, this technology can be found exclusively at several more expensive brands. However, thanks to Opel, it will now be accessible to a larger number of clients.
Buyers are able to combine new engine with front wheel drive or four-wheel drive (AWD). Insignia 2.0 CDTI BiTurbo is available in all body.
BiTurbo 2.0 CDTI new engine of 143 kW/195 hp output and 400 Nm of torque is designed to provide a very agile performance, quick and fluid when accelerating. Insignia sedan with front-wheel drive and six-speed manual transmission accelerates from 0-100 km / h in just 8.7 seconds and reaches a top speed of 230 km / h. At just 4.9 liters per 100 kilometers, fuel consumption and CO2 emissions (129 k / km) remain at low levels. All variants with manual transmission are equipped with Start / Stop, so Insignia become one of the most efficient midsize car in terms of fuel consumption. "In this class of power and torque, six-cylinder diesel engine displacement of 3 liters is the usual choice. With our BiTurbo technology, smaller engines develop more power and lower fuel consumption and facilitates emission levels with 30% lower", said Volker Scharf, chief engineer for the Insignia. "This is a great example of reducing displacement made by Opel."
Sequential turbocharging ensures smooth power delivery: in the Insignia's innovative BiTurbo two turbochargers of different sizes acts either individually or as a whole. Among its competitors, Opel is the only midsize car manufacturer to offer this sophisticated integrated two sequential turbochargers in diesel engines. Smaller turbocharger ensures rapid acceleration to extremely lower engine speeds. This means that the accelerator pedal responds immediately and turbine mid-way delay is eliminated. Starting with a speed of 1250 rpm, the driver can immediately get a couple of 320 Nm and a maximum of 400 Nm is reached at 1750 rpm. In medium speed range, both turbochargers work together and higher turbocharger compresses the air in advance before it is fully compressed in the smaller turbocharger. A bypass valve is controlled to transmit a continuous part of the exhaust gas turbocharger. Consequently, the driver will continue to enjoy strong acceleration. At higher speeds (starting at about 2500-3000 rpm), all gases are sent directly to the higher turbocharger, maintaining an even distribution of power at higher speed.
The main objective in developing BiTurbo 2.0 CDTI engine was to provide a quick boost pressure in the low speed range, while giving the throttle a heightened sensitivity in the medium speed range. Small intercooler cools the air entering the engine with water, after passing through the turbocharger smaller. In medium speed range, largest and most powerful turbocharger comes increasingly more in the process. Higher air flow and is cooled by conventional intercooler, larger.
Opel is the first brand of motor vehicles using such a "double cooling". Opel has optimized its engines by driving innovative Cleantech technology that controls combustion process in a closed loop electronic circuit. Sensors integrated into the glow plugs measure pressure 100,000 times per minute, providing always optimal engine operation in its parameters and also allowing minimum fuel consumption and emissions.
Direct injection system
The third generation common rail direct injection system, operating at pressures up to 2,000 bar, transmit ultra-precise fuel nozzles activated by piezoelectric providing eight injections per operating cycle. This ensures extremely precise combustion process, noise and emissions are minimized. With new BiTurbo 2.0 CDTI engine, the best room, Insignia model range now features four turbo diesel common rail direct injection, which develops an output of 81 kW/110 hp and 143 kW/195 hp. An offer without rival in the midsize car segment.
While improved version of the September 2011 model and main objective was for the low fuel consumption of its best selling models (new ecoFLEX 1.4 Turbo petrol engine with a emissions of just 134 g CO2/km and the new 2.0 CDTI ecoFLEX version of 118 kW/160 hp and emitting only 115 g CO2), the new features launched in early 2012 gives to the model premium quality and technology.
The new engine 2.0 CDTI BiTurbo is available for Insignia’s all body variations: 4-door hatchback, 5-door sedan and Sports Tourer station wagon. Customers can also opt for a manual transmission or six-speed automatic and the front-wheel drive or all-wheel drive (with electronic limited slip rear differential).
Driving dynamics can be further enhanced through adaptive mechatronic chassis FlexRide option. This variety of options is unmatched in the midsize car segment.
SuperSport chassis with high performance suspension available for all-wheel drive.
SuperSport Insignia chassis is optionally available with another significant innovation. This technology, originally designed variants of the best sports, the OPC (Opel Performance Center), is now available for a greater number of customers. The package consists of FlexRide mechatronic system, supplemented by a powered electronic adaptive damping system, Brembo braking system and suspension HiPerStrut high performance (high performance suspension) at the front, that initially was present on Insignia OPC version with 239 kW/325 HP, which optimizes handling and precision steering system.
Driver assistance systems
The new driver assistance systems based on radar technology provides additional security functions, not only to enhance performance and have been optimized: active safety was also enhanced due to the integration of a new radar sensor, located behind the radiator grille . Insignia buyers can now opt for Adaptive Cruise Control (ACC) radar sensors. This new system maintains the selected speed during movement speed cruising, but automatically adjusts the speed depending on traffic conditions to ensure that is a preset safe distance from the vehicle in front.
Together with radar sensors are available several positions: Position tracking distance indication (FDI) informs the driver via visual signals in relation to distance from the vehicle in front, frontal collision warning system (FCA) beeps and visual warning to the driver of an imminent collision with a vehicle in front and emergency braking system crash imminent (CIB) which automatically decelerates the vehicle if danger of collision is detected.
