Maybach's onboard fragrance systemThe luxury branch of Mercedes felt it necessary to appeal to all five senses when designing its S580 model. Where many of us opt for a mirror-hung scented pine tree to freshen up our vehicle, Maybach had other ideas in mind. The high-tech Air Balance system is far more advanced than a traditional air freshener and has real advantages, especially if you live in an area with increased air pollution or traffic congestion.Maybach's onboard fragrance system not only masks unpleasant odors by emitting a choice of four scented aromas directly into the vehicle's climate control unit. It also purifies the in-car atmosphere with air filters, which remove harmful irritants such as dust and pollen. A built-in ionizer also zaps air particles with an electric charge so they become attached to the filter upon contact. The atomizer, which produces the scent, sits in the glove box in an attractive vial, and it can be activated and controlled via the car's infotainment system.Once you understand the technology behind the Air Balance system, it makes absolute sense. This is much more than a simple air freshener, and those who suffer from allergies and breathing conditions would undoubtedly benefit from it. The unit has also been introduced to cars lower down in Mercedes' ranking order, including the G-Class, E-Class, S-Class, GLE, and GLS models.Land Rover's emergency escape hatchLand Rover's Range Rover model has been around since 1970 and appeared in countless movies and TV shows, from "The Sopranos" to the "James Bond" franchise. It is one of the original sports utility vehicles, and it looks equally at home tackling rugged terrain or dropping someone off at a red-carpet event. Yet, despite this broad appeal, we have to wonder at the type of market Land Rover identified as warranting the installation of an escape hatch on its Range Rover Sentinel model.Take a closer look at the Sentinel, and things start to become clearer. Even the name suggests that it is meant to guard and protect its occupants. This tank-like model is equipped with steel plating that can withstand impacts from high-velocity armor-piercing rounds or a blast from an improvised explosive device, depending on the type of day you're having. If passengers are ambushed and rendered sitting ducks, phase two of Range Rover's plan comes into play.Adjacent to the rear seats is an escape hatch, so the targeted official, prime minister, cartel owner, or oil magnate can wriggle to freedom, having suffered little more damage than a couple of grass stains to their Armani suit. This kind of security came at a price of over $400,000 at the time of its 2019 release. However, you were also treated to a five-liter supercharged engine, special run-flat tires, armored glass, a built-in public address system, and a siren and emergency lighting as options.
