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.

Toyota, Lexus will offer low-cost automated braking system

First, a technology gets better, then it gets a lot better, then it gets less expensive, then it gets a lot less expensive. Advanced driver safety and convenience systems are about to make that last step thanks to Toyota. Centered around a pre-collision braking system, there will be three suites of driver aids known as Toyota Safety Sense C (TSS C) for compact cars, Toyota Safety Sense P (TSS P) for midsized and premium cars, and Lexus Safety System+ (LSS+) for the luxury brand. TSS C pairs a camera with laser radar to provide a pre-collision system that prompts the driver to brake if it detects an impending accident, and can supply additional braking force and automatically brake between seven and fifty miles per hour. There are also Lane Departure Alert and Automatic High Beam. TSS P pairs a camera with more precise millimeter-wave radar. Starting with the three functions in TSS C, it adds pedestrian pre-collision capability and adaptive cruise control. This one will be available first, coming on the new RAV4 Hybrid and Avalon. TSS - either C or P - will expand to three more vehicles by the end of the year. The wallop is in the price: TSS C will be a $300 option, TSS P will cost $500. Compare the Ford Fusion SE, for instance - it's Driver Assistance Package comes with Lane Departure Warning, Automatic High Beams, it has Lane Keep Assist, Blind Spot and Cross Traffic Detection that neither TSS has, but doesn't have any autonomous braking feature. It costs $1,200, but requires you to add the Technology and Luxury Packages for a total price of $3,165. If you want Autonomous Cruise Control, that's another $995, for $4,160 in total. Instead of $300 or $500 on the Toyota. Lexus' LSS+ will come first on the new RX then spread to four more models by the end of this year, and cost between $500 and $635 to add as an option. It also uses a camera and millimeter-wave radar for its vehicle and pedestrian pre-collision system, lane departure warning and lane keep assist, automatic high beam, and auto cruise control. The similar package on a BMW X5, with no pedestrian component, is $1,200. Toyota says both safety suites will eventually be on "nearly all" of it products and all trim levels by the end of 2017.

2014 Toyota Highlander to start at $30,075*

We now have pricing for Toyota's redesigned 2014 Highlander, which is seeing moderate price hikes across the board. Prices for the popular crossover have been bumped from less than 1 percent to less than 3 percent on lower-end models (anywhere from $125 to $890, depending on trim). Toyota has increased prices on higher-end XLE and Limited models more substantially - between 4.1 and 4.5 percent ($1,480 to $1,700). The Highlander Hybrid sees its price increase 2 percent ($930). The new model will be available in four different trims and with either front or all-wheel drive.
The absolute cheapest member of the Highlander range, the base LE, with a four-cylinder and front-wheel drive starts at $30,075, an increase of just $195. The LE is also available with a V6 and all-wheel drive, with the bigger engine upping the price to $31,380. All-wheel drive models start at $32,840. A slightly pricier LE Plus starts at $33,600 for a V6 FWD model and $35,060 if you add all-wheel drive.
Next up, we have the XLE, which starts at $36,900 for FWD models and moves up to $38,360 for AWD. The top-tier Limited model starts at $40,500 in FWD spec, grips-at-all-fours versions will retail for $41,960. For those that want the very top of the Highlander range, there's the Platinum Pack, which adds the Driver's Tech Pack (adaptive cruise control, pre-collision warning, lane departure warning and automatic high beams), a panoramic moonroof, heated steering wheel and heated second-row seats to the already well-equipped Limited model. Highlander Platinums start at $42,990 and $44,450, depending on how many tires are doing the work. (Note: All prices include an $860 destination and handling charge.)
