Audi celebrates 500k TT models with new TTS Competition

The stylish Audi TT first debuted in 1998, and while we've only seen two generations of the car over the course of 15 years, some 500,000 examples have been sold. To mark the occasion, Audi has created this special TTS Competition model, available as either a coupe or a roadster and limited to just 500 units.
Competition models are set apart from the rest of the TTS range by their unique paint colors - Imola Yellow and Nimbus Gray. Additionally, the limited-run TTS wears new five-spoke, 19-inch alloy wheels and features a fixed rear wing (like the one on the TT RS).
Leather upholstery is found inside the cabin, done up in steel gray with yellow accents. Of course, there are special numbered plaques on the door trims, simply saying "1 of 500."

Audi R8 V10 Plus vs. Renault Clio Cup racecar will make you go hmmm...

Match up a hot hatch with a supercar of the same vintage, and we'll tell you who will win every time. It's easy, really, as the supercar invariably features a more advanced suspension, stickier tires and most importantly, more power. What if the hot hatch is race prepped, though?
In that particular case, all bets are off. A circuit-tuned suspension, a stripped-down cabin, an ultra-quick sequential transmission and the greatest equalizer of them all, slick tires, are all that's needed to turn the typical hot hatch into a proper dragon slayer.
Perhaps seeking to prove this, Evo has put together an interesting head-to-head between the Audi R8 V10 and a race-prepared Renault Clio Cup. Host Dickie Meaden takes us through each car, highlighting the bits and bobs on both sides which should make this a tight competition. And boy, is this one tight.

Recharge Wrap-up: Ferrock a carbon-negative cement substitute, Audi makes e-diesel

A cement alternative uses recycled materials and traps CO2 rather than producing it. Invented by David Stone at the University of Arizona, Ferrock uses recycled steel dust and glass to produce a substance stronger than conventional concrete. Cement has a high carbon footprint from the high heat needed to process the limestone. Ferrock needs no such heat, and it actually uses CO2 to harden, making it, as Stone calls it, a carbon-negative material.

Part of the Firmware 6.2 update, Valet Mode allows the owner to disable certain performance features and block personal information when letting someone else drive the car. It limits the car's to speed to 70 miles per hour, and caps output at 80 kW. It can also disable mobile app access, Homelink, Bluetooth and wifi and the "Places" function, which stores addresses for you. The folks at Teslarati did find some shortcomings in the new feature, though. Read more at Teslarati. Audi has produced its first batch of e-diesel made from water and CO2. The fuel is made by reacting hydrogen from the water with CO2 to make long-chain hydrocarbon compounds called "blue crude." That can then be refined similarly to crude oil to make e-diesel, which is a fuel free from sulfur and aromatic hydrocarbons. That e-diesel can be used on its own, or mixed with fossil fuel diesel to power a vehicle. "In developing Audi e-diesel we are promoting another fuel based on CO2 that will allow long-distance mobility with virtually no impact on the climate," says Audi Head of Sustainable Product Development Reiner Mangold.

Fuel of the future: Research facility in Dresden produces first batch of Audi e-diesel - The verdict: Pilot plant produces high-quality diesel fuel - No need for mineral oil: e-diesel made from water, CO2 and green power - Minister Wanka: "Synthetic diesel using CO2 is a huge success" Audi has taken another big step in the development of new, CO2 neutral fuels: A pilot plant in Dresden has started production of the synthetic fuel Audi e diesel. After a commissioning phase of just four months, the research facility in Dresden started producing its first batches of high-quality diesel fuel a few days ago. To demonstrate its suitability for everyday use, Federal Minister of Education and Research Prof.
