Top Down, New Engine On: Opel Cascada Drives into Summer

Jun 10, 2015

  • Stylish: Attractive convertible with premium roof and room for four adults
  • Clean: New turbo diesel with 125 kW/170 hp and just 4.9 liters consumption
  • Purrs: Whisper diesel perfect for open-air driving

Opel News - Seductive whirlwind: Opel gives the Cascada a brand-new 125 kW/170 hp two-liter turbo diesel engine

Rüsselsheim. An elongated, elegant silhouette, state-of-the-art technology and extensive standard equipment – in one word: Cascada. With the large convertible, Opel offers a spacious four-seater with a high-quality soft-top otherwise only seen in selected premium brand vehicles. It features superior acoustic and thermal insulation for first-class, all-season driving comfort. The Opel Cascada is a seductive whirlwind with its top down and a quiet Gran Turismo when the top is up. It is a year-round cabriolet thanks to its sophisticated soft-top that opens in just 17 seconds while driving at speeds of up to 50 km/h. And now Opel gives the Cascada the brand-new two-liter turbo diesel engine recently introduced in the Insignia and Zafira Tourer, as well as the three new colors True Blue, Rocky Coast and Coconut. The new 125 kW/170 hp four-cylinder unit with 400 Nm torque meets all the important demands on modern diesel engines and replaces the 121 kW/165 hp engine.

Opel News - Purrs: Whisper diesel 2.0 CDTI perfect for open-air driving

Compared to its predecessor, the new powerhouse boasts three percent more power and 14 percent more torque, yet has even more economical consumption. With the new two-liter turbo diesel under the hood and six-speed manual transmission, the open-air cruiser consumes just 4.9 liters per 100 km in the combined cycle and emits 129 g/km CO2. Thus, the Euro 6-2.0 CDTI boasts improvements of six percent. The powerful engine is a perfect fit to the comfortable and lively Cascada: the Opel convertible accelerates to 100 km/h in 10.3 seconds and reaches a top speed of 218 km/h. It makes the sprint from 80 to 120 km/h in fifth gear in just 9.3 seconds – seven-tenths faster than with the predecessor engine. The elegant convertible with the new 2.0 CDTI engine is available from 30,500 euros (RRP incl. VAT in Germany).


“The Opel Cascada is a mid-size cabriolet with premium features and quality for an extremely attractive price. With the new engine that is part of our extensive powertrain offensive, cabriolet fans now get an engine that sets standards in this class in terms of refinement, power development and consumption,” says Peter Christian Küspert, Vice President Sales and Aftersales at Opel Group.

Highest efficiency for low consumption

The engineers managed to achieve the efficiency improvements by redesigning the combustion chamber, optimizing the re-profiled intake ports and looking to a new fuel injection system with 2,000 bar and up to 10 injections per cylinder cycle. These measures not only improve the efficiency of the engine, the improved fuel atomization also benefits refinement. Impressive maximum torque of 400 Nm is available from 1,750 to 2,500 rpm. For the first time the VGT (variable geometry turbine) turbocharger features an electrical actuator instead of a vacuum actuator resulting in 20 percent faster boost response and even more driving fun. The exceptionally compact packaging of the turbocharger and the intercooler also minimizes the air volume between the turbocharger and the engine, further contributing to an especially fast boost pressure build up. For durability, the turbocharger is water-cooled and has an oil filter fitted at the oil inlet point to help further reduce wear in the bearing system.

Smooth running for pure cabriolet feeling

A consistent improvement in NVH (noise, vibration, harshness) characteristics under all operating conditions was a key requirement for the new engine right from the outset of its design. Architectural improvements focused on two high noise emitting areas: the top and bottom of the engine. A new aluminum cylinder head design, including the addition of a decoupled, plastic cam cover with isolated fixings and a sealing gasket, improves noise attenuation. At the bottom of the engine, a new balancer shaft module is fitted, made of high pressure die-cast aluminum. It houses two counter-rotating shafts which offset up to 83 percent of secondary order engine vibrations. As a result of all these and numerous other design features, the new 2.0 CDTI unit emits less noise than its predecessor throughout its operating range, and with 74 decibels at idle it is even three decibels quieter than before. This takes the open-air driving fun in the Cascada to new heights.

Clean running with Selective Catalytic Reduction (SCR)

The new 2.0 CDTI runs almost as clean as a gasoline engine with Opel’s BlueInjection selective catalytic reduction (SCR) system. BlueInjection is an after-treatment which removes nitrogen oxide (NOx) from the engine’s exhaust gases. Tiny quantities of AdBlue®, a harmless fluid consisting of urea and water, are injected into the exhaust gas flow ahead of the SCR catalyst and downstream of the Diesel Particulate Filter (DPF). The solution is immediately converted into ammonia (NH3), which is absorbed by the SCR catalyst. Nitrogen oxide (NOx) in the passing exhaust gas is then selectively reduced to harmless nitrogen and water vapor in a chemical reaction with the ammonia. The AdBlue solution, available at filling stations and Opel dealerships, is stored in a tank, which can be topped up as required via a nozzle adjacent to the vehicle’s fuel filler cap.


Opel OnStar: The all-round carefree package for the Cascada

Ultra-modern technology is not only under the Opel Cascada’s hood: from late summer, the mid-size convertible will also be available with the personal connectivity and service assistant Opel OnStar. The built-in 4G LTE connection enables mobile data speeds up to 10 times faster than with 3G technologies. The system offers increased responsiveness and can support simultaneous voice and data connections. Opel OnStar raises in-vehicle communications and on-board entertainment capabilities to a new level. Thanks to the powerful Wi-Fi hotspot, up to seven mobile devices can be connected to the system simultaneously.
