2014 Volkswagen XL1 [w/video]

World's Most Efficient Car Impresses, Not Without Compromises
Among our many duties at the recent Geneva Motor Show, we were offered a pretty exclusive drive in the new Volkswagen XL1 hyper-efficient plug-in diesel hybrid. There is so much that is interesting about a car like this reaching production from a major automaker that it's tough to know where to begin.
First off, you should know that - at least for this generation - there is absolutely no chance in Albuquerque that this "1-liter vehicle" (i.e. a vehicle that can burn just one liter of fuel to travel 100 kilometers, or 62.1 miles) will ever make it into the hands of North American customers. We, too, were having trouble imagining an XL1 in typical American traffic, surrounded by comparatively massive pickups and SUVs. The driving experience had us recalling a couple of weeks in 1999 when we drove the then-revolutionary Honda Insight hybrid on US roads. We keenly remember the feeling of being very small and vulnerable, even as we felt proudly green in our 61-mpg Tochigi pod. Thing is, the Volkswagen is smaller still, and nearly as light despite its more complex drivetrain and safety features.

The tumultuous history of the diesel engine

Volkswagen, diesel's most enthusiastic patron, deceived everyone about the amount of emissions its cars were putting out. We have covered this latest massive automotive scandal in great detail, and there are surely more fascinating revelations to come. It turns out that this is just the latest episode in the epic story of the controversy and intrigue surrounding the diesel engine, and its inventor. This is the story of the tumultuous birth and interesting evolution of the compression-ignition engine at the center of the VW scandal. Napoleon III Got Rudolf Diesel Deported Rudolf Diesel was born in Paris in 1858. His Bavarian parents had settled in France where his father, Theodor, was a leather goods manufacturer. When the French Parliament declared war on Prussia, kicking off the Franco-Prussian war, the Diesels fled to London. When he was 12, Rudolf went to live with his aunt and uncle in the Bavarian university town of Augsburg. It was his parents' hometown, and importantly, it's where Rudolf began studying at the Royal County Trade School. His time in Augsburg, graduating at the top of his class from trade school that laid the groundwork for all that was to come. Diesel Nearly Blew Himself Up An early career in refrigeration saw Diesel running R&D in Berlin for Linde, a company started by refrigeration pioneer Carl Von Linde, one of Diesel's professors. His ambition to branch out beyond refrigeration, and his deep understanding of thermodynamics, led to efficiency experiments with steam engines. Diesel was trying to create an engine that didn't waste heat from the combustion process, therefore getting the most work out of the fuel. Instead, he was nearly killed when an experimental ammonia vapor steam engine exploded. Recovery took many months, and during some of that time, he was no doubt planning his next experimental engine, based on the theoretical Carnot cycle. His Engine Was An Attempt To Stick It To The Man Steam engines were expensive to run and wasteful. Diesel thought the efficiency of his design would be a way for the small business to compete with the dominant industrial giants. It was, and it did, but big business is equally passionate about chasing efficiency. Diesel engines quickly proliferated in industries both grand and cottage. Rudolf Didn't Really Invent The Diesel As We Know It Instead, he improved an existing one to a significant degree. The Diesel engine could be considered an evolution of the "hot-bulb" engine.

Why this could be the perfect time for Apple to make a car play

While the automotive and technology worlds have been pouring billions into autonomous vehicles (AVs) and preparing to bring them to market soon as shared robo-taxis, Apple has mostly sat on the sidelines. Of course, Apple is the last company to ever make its intentions known, and the super-secret tech cult giant hasn't been totally out of the AV game based on the clues that have slipped out of its Cupertino, Calif., citadel over the past few years. Related: Apple self-driving cars are real — one was just in an accident News first broke in 2015 that it had assembled an automotive development team, in part by poaching high-profile talent from car companies, to work on a top-secret self-driving vehicle project code-named Titan. (Thank you very much, Nissan.) Apple also subsequently broke cover by making inquiries into using a Northern California AV testing facility and receiving a permit to test AVs on public roads in California. But then as the AV race started to heat up in the last few years, Apple reportedly began scaling back its car activities by downsizing team Titan. More recently, Apple's car project has shown signs of life with the hiring a high-level engineer away from Waymo and luring one Tesla's top engineers and a former employee back to Apple. It also inked a deal with Volkswagen to provide a technology platform and software to convert the automaker's new T6 Transporter vans into autonomous shuttles for employees at tech company's new campus. That is a far cry from giving rides to Wal-Mart shoppers, like Waymo is doing as part of its AV testing in Phoenix. But this could be the perfect time for Apple to enter the AV market now that ride-sharing is reaching critical mass and automakers and others are planning to deploy fleets of robo-taxis. Apple could easily establish a niche as a high-end ride-sharing service – and charge a premium – given its cult-like brand loyalty and design savvy. The growth of car subscription models could also play in Apple's favor since is already has many people hooked on paying for phones in monthly installments – and eager to upgrade when a new and better model becomes available. To achieve this, some believe Apple will fulfill co-founder and CEO Steve Job's dream of building a car. And as the world's first and only $1 trillion company it's sitting on a mountain of cash that certainly gives it the means. But other tech darlings like Tesla and Google have discovered how difficult it can be to build cars at scale.
