Bosch Aerotwin clear winner in windscreen wiper blade test
The Bosch Aerotwin has emerged as the clear winner in all areas in the latest ADAC wiper blade test, which was first advertised on the German automobile club's homepage.
The Aerotwin flat blade was the only wiper blade to be categorised as "very good". Alongside five non-jointed windscreen wipers, which are known as planar or aero wipers, five curved wipers were also tested — all of which were "relevant and interesting wiper blade brands", according to the 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 high and low temperatures. Overall, the more modern non-jointed windscreen wiper blades achieved better results than the conventional curved wipers.
Easy installation with multi-clip universal adapter
The long service life of the Bosch Aerotwin flat blade was also taken into account and its installation on the car and the wiper arm fastening also contributed to its top score. The ADAC testers criticised other wiper blades for being frequently problematic to install on cars and called for "more user-friendly, standardised 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 pre-installed 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 wiper blades, 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 wiper blades. Drivers should also choose a modern simpler wiper blade, 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 customised Evodium spring strip that is a perfect fit for the curvature of the windscreen. This guarantees an even surface pressure and therefore en¬ables perfect wiping performance at every point on the windscreen. 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 windscreen, the Bosch Aerotwin offers a longer service life.
