Cabin air filters have been installed in vehicles for the past two decades and are designed to improve the air quality as it enters the interior of your vehicle.  That’s why it’s important to periodically replace the cabin air filter in your vehicle from time to time.  But how do you know when your cabin air filter needs to be replaced? What Does A Cabin Air Filter Do? Cabin air filters as the name suggest filters air as it flows into the interior or cabin of your vehicle.  Cabin air filters have been installed in cars since the early 2000s as a way to improve the air quality inside vehicles. How Often Should You Change Your Cabin Air Filter? The mileage at which you should replace your cabin air filter will be mainly dependent on how much dirt, soot, and debris you regularly drive through. If you live in an area where you regularly have to drive down untarred roads then you would need to replace your cabin air filter more frequently than someone that mainly does city/highway driving. 

Back in 2017, Rolls-Royce unveiled the Sweptail, an incredibly huge Phantom-based one-off coupe with a completely custom coach built body, the first of its kind from Rolls in the modern era. Right after the Sweptail was revealed, Rolls-Royce had a number of clients asking for custom vehicles of their own, leading the company to today announce that it's spinning off Coachbuild into a division of the brand. But three particular customers had very similar visions of what they wanted, and after four years of development, the new Boat Tail was born. Three Boat Tails will be built, one for each of said customers, and each one will have its own unique styling elements, colour and trim specs and special features. So far, only one car has been built -- the blue one you see here -- and Rolls-Royce isn't ready to talk about the other two yet. <script async src="https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js?client=ca-pub-2583627563363777"      crossorigin=&quo

Nissan Qashqai  Nissan is developing an engine for road cars that could reach 50% thermal efficiency, meaning the potential for much more fuel-efficient cars. An engine's thermal efficiency is a measure of how much of the heat energy generated by combustion is actually converted into useful work. A good rating for a road car is about 40% whereas 50% is a rating normally associated with the best Formula One engines. Most cars particularly older models are have 20%-30% efficiency ratings. Nissan said Friday that an engine designed for road cars could achieve 50% thermal efficiency, but there's a catch: the engine would need to be running at a constant rpm, for example when used as a generator in an extended-range electric vehicle. In a conventional car, an engine experiences a wide variety of rpm and loads, which prevents it from running in its most optimal state due to the rich air-fuel mix required at certain rpm levels. This isn't the case for an engine acting as a generat
