Opel Monza Concept
Opel Monza Concept Interior
German automaker Opel has several vehicles on display at the 2013 Frankfurt Motor Show, but only one comes with a plug: the Opel Monza Concept.
There's no way this concept will make it into production, so we'll keep our blurb here brief.
Opel says the Monza Concept previews next-generation Opels and that it's a further development of the technology found in the Ampera (aka Volt).
The tie to the Ampera and Volt is all that we'll deal with here.
The Opel Monza Concept features GM's next-generation three-cylinder 1.0 SIDI turbo engine. In the Monza Concept, this engine acts as a range extender and burns CNG (compressed natural gas).
We don't expect to see CNG listed as a fuel option on the next-gen Volt, but we do suspect that this engine might be the unit that handles the Volt's range-extending duties.
So, what should we expect from this engine? Well, it too made its debut in Frankfurt, so details are limited, but here's what Opel released so far:
New All-Aluminum 3-Cylinder Turbo Sets Refinement Benchmark
New 85 kW/115 hp, 1.0-liter turbo raises bar for three-cylinder refinement
First in all-new family of small-displacement direct injection gasoline engines to debut in Opel ADAM
Higher torque, better fuel efficiency than 1.6-liter engine
Cylinder head-integrated exhaust manifold
Teamed with all-new six-speed gearbox, 30 percent lighter than predecessor
Opel's 1.0 Liter 3 Cylinder
Rüsselsheim/Frankfurt. Clean, smooth and quiet: Opel’s all-new three-cylinder celebrates its world premiere at the Frankfurt International Motor Show (September 12 - 22, 2013). The 1.0-liter turbo gasoline engine is not only climate-friendly, it also represents a new benchmark for refinement in three-cylinder engines, with noise and vibration characteristics superior to many four cylinder units.
Developing 85 kW/115 hp, this pocket powerhouse also delivers high low-end torque of 166 Nm all the way from 1,800 to 4,700 rpm, belying its diminutive size. The 1.0 SIDI Turbo (Spark Ignition Direct Injection) generates more torque throughout its operating range than equally powerful, higher displacement engines, while fuel efficiency is improved by 20 percent compared to Opel’s current 1.6-liter naturally aspirated power unit.
To be launched in the ADAM small car next year with an all-new six-speed manual gearbox, the 12-valve, 1.0 turbo is the first in a new, modular family of three and four-cylinder gasoline engines in the up to 1.6 liters class. State-of-the-art technologies such as direct injection, continuously variable valve timing, and a lightweight aluminium cylinder-block, are key efficiency enablers. Opel expects the new engine family to deliver impressive fuel economy and CO2 emissions significantly lower than 100 g/km.
“In developing this small engine, we not only set out to minimize fuel consumption and CO2 emissions, we also wanted to demonstrate that three cylinders can be just as refined as four or more,” says Dr. Matthias Alt, Opel’s Chief Engineer, Small Gasoline Engines. “We tackled at source the balance, noise and vibration issues typical of conventional three-cylinder engines, and we’re confident customers will be pleasantly surprised by the results. This is a very lively and refined three-cylinder engine which doesn’t compromise on driving fun.”
