- Consistent lightweight design: Five-door model up to 200 kilograms lighter
- Engineered from white sheet of paper: Every component trimmed to highest efficiency
- Compact: All-aluminum engines and interior concept save more weight
- Intelligent architecture: More space in slimmer shell
|Consistent lightweight design: New Opel Astra is up to 200 kilograms lighter than its predecessor|
The visionary Monza Concept presented at the 2013 IAA was the role model for Opel’s eleventh compact class generation. Every component of the study reflects the efficiency maxim. The new Opel Astra already consistently realizes this vision: depending on the model and trim level, it is up to 200 – but in any case at least 120 – kilograms lighter than its predecessor. The new, thoroughly slimmed down vehicle architecture plays a decisive role in this weight loss: the bodyshell (body-in-white) and structure alone are over 20 percent lighter, down from 357 to 280 kilograms. Another 50 kilograms were saved in the design of chassis components: high-strength and ultra-high-strength lightweight steels, more compact subframes as well as modification to the front and rear suspensions all contributed to this end result. In addition, engineers decided against full underbody paneling to further optimize the aerodynamics of chassis and drivetrain elements, resulting in a double advantage: lower weight and reduced production costs that enable more attractive price structures for customers.
Further size- and mass-optimization measures include shorter front and rear overhangs, as well as the up to 25 percent lighter exhaust system which saves around 4.5 kilograms on this part alone. The smaller wheels and tires weigh up to 11.5 kilograms less. The same is true for the brakes: as the system has less mass to decelerate, a more compact design weighing 10 kilograms less was possible – while delivering even better braking performance.
Lose the weight: Engines make their contribution
Another plus on the efficiency side is the new-generation engines. They distinguish themselves with their compact and ultra-efficient design: for instance the new 1.4 ECOTEC Direct Injection Turbo engine making its premiere in the Astra weighs much less than current comparable units. Its aluminum engine block alone is ten kilograms lighter than the cast-iron block of its predecessor. Thanks to their compact design, the newest-generation, ultra-modern transmissions save just as much weight.

Reduced weight also leads to noticeably higher agility. The new Astra is more fun to drive than ever before – while saving fuel and CO2 emissions. The newcomer with the 1.0 Turbo and Easytronic 3.0 combination is one of the most economical and cleanest gasoline models in its segment. The 77 kW/105 hp three-cylinder unit reduces consumption in the combined cycle to 4.2 liters per 100 kilometers and CO2 emissions to an exemplary 96 g/km.

The interior was also put through a fitness program. Take, for instance, the seats: after five years of detailed work, the development team presented compact class seats that are more functional and comfortable, while featuring more of a space- and weight-saving design than ever before. State-of-the-art packaging calculation methods enable this, as do lighter polyurethane foams and ultra-high-strength steels that are built in under the robust seat upholstery. So the new Opel Astra seats in front and rear are a total of around ten kilograms lighter than in the previous model.
Intelligent packaging: Lighter, more compact yet more spacious
