Opel Powertrain Offensive: The Best Diesel Portfolio Ever

Feb 23, 2015

  • New generation whisper diesels impress with outstanding refinement
  • Premium efficiency combines driving fun and responsiveness with frugality
  • Exemplary exhaust gas treatment with low nitrogen oxide emission


Opel News - Opel Insignia & Mokka

Rüsselsheim/Dublin.  The Opel product offensive is in full flow with 27 new models and 17 new engines being brought to market between 2014 and 2018. Thereby the diesel engines for each model range will be completely modernized. Today, Opel already has the most modern diesel portfolio of all time. With the introduction of the new 2.0 CDTI in the first half of 2015, a new generation of whisper diesels is available for cars ranging from Corsa to Insignia in three displacement classes. These 1.3-liter small, 1.6-liter mid-size and 2.0-liter large units have all been developed according to a common philosophy:

 

  • Improve efficiency and reduce all kinds of emissions,
  • improve responsiveness and low-end torque,
  • dramatically reduce the level of noise and vibrations to improve comfort.


1.3 CDTI – the small but able consumption marvel

Opel News - Engine Development Torino

The new 1.3 CDTI has just been launched with the new Corsa - which can already boast over 120,000 orders. This engine is available with outputs of 55 kW/75 hp and 70 kW/95 hp, both giving 190 Nm maximum torque. It has been developed to be much quieter than its predecessor in the previous generation Corsa and to also offer much better responsiveness. New-generation turbochargers ensure smooth driving and acceleration at low engine speeds with minimal noise generation. Both versions come with fuel-saving Start/Stop technology fitted as standard. The most frugal Corsa diesel version – with 70 kW/95 hp, automated Easytronic 3.0 transmission and braking energy recuperation system – can reduce CO2 emissions to 82 g/km and fuel consumption to 3.1 l/100 km in the combined cycle. This has earned it Germany’s A+ energy efficiency label (according to Regulation [EC] No 715/2007).

1.6 CDTI – the spirited whisper diesel

Opel News - The new 1.6-liter turbo diesel

The new generation all-aluminum four-cylinder 1.6-liter diesel engine is the star in the compact class. Hailed by the trade press as the ‘whisper diesel’, it made its debut in the Zafira Tourer in late 2013 with an output of 100 kW/136 hp. An 88 kW/120 hp version followed quickly. The 1.6 CDTI is now also available for the Meriva (with 70 kW/95 hp, 81 kW/110 hp and 100 kW/136 hp), the Astra (81 kW/110 hp und 100 kW/136 hp), and the sporty Astra GTC (100 kW/136 hp). The new 1.6-liter turbo diesel is rated as the quietest and most efficient in its class.

Opel News - This engine is now also available for the Opel Mokka

This engine is now also available for the Opel Mokka and impresses with its outstanding refinement, low consumption (a mere 4.1 liters of diesel per 100 kilometers over the combined cycle, this is equivalent to 109 g/km CO2) and its feistiness. The Mokka 1.6 CDTI accelerates from zero to 100 km/h in 9.9 seconds, and makes the transition from 80 to 120 km/h in fifth gear in just 9.9 seconds.

2.0 CDTI – the squeaky-clean top-of-the-range diesel

Opel News - Opel Insignia Coutry Tourer - new Opel diesel pack, the refined 2.0 CDTI

The leader in the new Opel diesel pack, the refined 2.0 CDTI, has just been introduced. The new four-cylinder powerhouse offers impressive torque of 400 Nm and maximum power of 125 kW/170 hp is reached at just 3,750 rpm. It propels the Insignia from 0 to 100 km/h in only nine seconds and to a maximum speed of 225 km/h. This spring, the new 2.0 CDTI will also be introduced in the Zafira Tourer (125 kW/170 hp) and, later, in further Opel models such as the convertible Cascada.

Opel News - The new 2.0 CDTI meets the stringent Euro 6

Just like all other Opel diesel engines, the new 2.0 CDTI meets the stringent Euro 6 emission standards. Drivers will be able to enjoy it without any regrets because Opel’s new generation diesels deliver outstanding emission levels comparable to those of a gasoline unit. The main weakness of diesel engines, the emission of nitrogen oxides, is history. The Insignia comes with Opel’s BlueInjection selective catalytic reduction (SCR) system, which removes nitrogen oxide 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 in the passing exhaust gas is then selectively reduced to harmless nitrogen and water vapor in a chemical reaction with the ammonia.
