press release

The Bosch Aerotwin emerged as the clear victor in all disciplines in the current ADAC windshield wiper test, which was first advertized on the german automobile club's homepage. The Aerotwin was the only windshield wiper to be categorized as "very good". Alongside five non-jointed windshield wipers, which are known as planar or aero wipers, five bowed wipers were also tested — all of which were "relevant and interesting wiper blade brands", according to a market analysis. Installation was tested on a VW Golf IV, with particular emphasis being placed on the wiping quality in summer conditions (+20°C) and winter conditions (-8°C). In addition, the wipers had to prove their quality when new, in a wear test and following artificial subjection to sunlight.

Grade 1 for Bosch Aerotwin in all test disciplines
The verdict of the ADAC testers was unequivocal — the Bosch Aerotwin stood out from the competition in all tests, in both positive and negative temperatures. Overall, the more modern non-jointed windshield wipers achieved better results than the conventional bowed wipers. Nonetheless, the second Bosch windshield wiper in the test—the Twin Spoiler—was not only named the best bowed wiper; it also achieved third place overall.

Easy installation with multi-clip universal adapter
The Bosch Aerotwin was not awarded a mark of "Very Good" just because of its excellent wiping results; its long service life was also taken into account. Furthermore, its installation on the car and the wiper arm fastening also contributed to its top score. The ADAC testers criticized wiper blades for being frequently problematic to install on cars and called for "more user-friendly, standardized connection elements between the wiper arm and blade." With the multi-clip universal adapter, Bosch has done exactly that for the Aerotwin model. The novel adapter, which is preinstalled on the wiper, is suitable for the different wiper arm types of the key passenger car series on the European market.

The ADAC's conclusion: When buying wipers, it is well worth paying a little more for a good quality product, as the high-quality and slightly more expensive products performed better in the test than the inexpensive ones. Drivers should also choose a modern planer wiper, which will retain a higher level of wiping performance for longer.

High-quality material combination for perfect wiping performance
The Bosch Aerotwin achieves its excellent wiping results through a customized Evodium spring strip that is a perfect fit for the curvature of the windshield. This guarantees an even surface pressure and therefore enables perfect wiping performance at every point on the windshield. The aerodynamic profile also ensures that the wiper does not lift up even at higher speeds and causes less wind noise. The wiper rubber is elaborately constructed with a flexible base, a wear-resistant edge and smooth-glide coating. Thanks to its hard-wearing rubber and even force distribution on the surface of the windshield, the Bosch Aerotwin offers a longer service life.
