The Insignia BiTurbo, Opel/Vauxhall’s most powerful diesel engine ever, is now available in the Insignia range. It is capable of delivering 195PS and 400Nm of torque and it has low CO2 emissions of 129g/km. This engine, which is currently on sale, is available in five-door Hatch and Sports Tourer versions in SRi, SRi Vx-line and Elite trim, with a starting price of £27,120 (33,405 Euro in Europe) on the road.
This powerful, twin-sequential turbocharged diesel is based on the existing 1956cc unit that is featured on key models in the Insignia and Astra and new Zafira Tourer range. But when in BiTurbo form, the engine can deliver as much as 35PS more power while its torque has been boosted by 50Nm.
This enables the vehicle to reduce its 0-60mph acceleration time by almost one second to 8.2 seconds (Insignia FWD Hatch). But with the help of a package filled with eco features (which include standard Start/Stop across the range), the FWD Hatch can provide a combined 57.6mpg.
This is an improvement of 2.2mpg compared to the single-turbo 2.0 CDTi 160PS model. What makes the Insignia BiTurbo exceptional in this class is its use of sequential turbocharging. At lower engine speeds, the smaller turbo can quickly accelerate and this removes ‘lag’, offering 350Nm of torque from only 1500rpm. These two turbochargers work together in the mid-range.
A bypass valve permits the gases to flow from the small to large unit. When in this phase, the maximum torque of 400Nm is made between 1750-2500rpm. Performance is maintained at higher engine speeds since from 3000rpm, all gases flow directly to the larger turbo.
This power increase is complemented by Vauxhall’s clever FlexRide adaptive damping, which is offered as standard on all Insignia BiTurbos. This is typically an option on front-wheel drive Insignias that costs £790. Within milliseconds, this system responds to driver inputs and it can ‘learn’ how the driver is handling the car. The damper settings are then adjusted accordingly. Drivers could choose from Tour and Sport buttons. The throttle, steering and damper settings in Sport mode can be selected separately.
The new Opel Insignia features a blade form that has been chiseled into the side, a styling cue that would become a signature attribute of future Opel cars. In addition, the Insignia is laden with several distinct design cues like its distinctive radiator grille with a newly designed Opel emblem and sweeping front and rear light units. Another Opel Insignia design element is the powerful tapered shape of the wing lighting signature.
According to Mark Adams, Vice President of Design for GM Europe, Opel has redefined its design vocabulary, with the styling of the new Insignia following the 'sculptural artistry meets German precision,' philosophy. He remarked that the new Opel Insignia is provided with beautiful, sculptural and fluid shapes as complemented by crisp intersecting lines – giving birth to a muscular, sporty vehicle that is also elegant and graceful. He added that the Insignia was designed to add emotion into the Opel and Vauxhall brands.
On the other hand, the interior of the new Opel Insignia boasts of shapes and surfaces made from high quality materials. It features dashboard wrapping around from the instrument panel to the door, hereby seemingly embracing the car’s occupants. In addition, the Insignia’s exterior "blade" graphic is featured inside through the shape of the steering wheel, door grab handle, and the central gear-shift lever.
The interior of the new Opel Insignia is laden with painstakingly refined surfaces as well as crisp intersecting lines and colors. Its designers worked hard to make sure that surface finishes inside the Insignia exude the highest quality.
Designers also did not fail to consider the practicality and convenience within the Insignia. In fact, the car features good ergonomics and comes with several storage compartments. Accentuating the interior of the Insignia is an orange-red ambient light that will also be adopted in future Opel models.
