2014 Audi A7 TDI

If you're a frequent reader of car reviews (my money says you are), you've no doubt come across prose about how a car "checks all the right boxes." It's a common phrase - I'm guilty of using it myself. And I'm about to use it again.
You see, I've just spent a week with the 2014 Audi A7 TDI, shown here against the backdrop of sunny SoCal, even though my stint was spent slopping through this absolutely wonderful winter we've been having in Detroit. If you're one of our podcast listeners, you've already heard me wax poetic about the A7 TDI, and the more I reflect on this diesel darling, the more I firmly believe that this car absolutely, without a doubt, checks all the right boxes.
Well, almost all of them, anyway.

2015 Audi R8 Competition ready to rock LA

The heyday of the first-generation Audi R8 is winding down, and the Four Rings already has a bespoke factory to start building the next model soon. In the meantime, the German brand is sending its supercar off with a bang at the 2014 Los Angeles Auto Show in the form of this limited-edition 2015 R8 Competition - the most powerful production vehicle ever made by the company.
Audi is earmarking just 60 examples of the Competition for the US, and this is more than just a trim package to say farewell. Power for the supercar comes from the usual 5.2-liter V10 that's massaged to develop 570 horsepower, an extra 20 hp over the already quite potent V10 Plus, and the only available transmission is the seven-speed, dual clutch S Tronic gearbox. The tweaks let this limited R8 rocket to 60 miles per hour in 3.2 seconds and achieve a maximum velocity of 199 mph. To haul that speed to a stop, it also gets ceramic brake disks with red calipers.
Of course, having such a rare supercar means showing off a little. Audi takes inspiration from the R8 LMS Ultra racecar for the Competition and tries to bring some of its details to the street. The model wears matte carbon fiber pieces replacing the rear spoiler, mirror housings, side blades, front spoiler and rear diffuser. For an extra mean-looking touch, it also has high-gloss black paint covering the wheels and exhaust pipes.

To solve diesel problem, VW might need two fixes

Volkswagen says that a fix is on the way for its 11 million vehicles around the globe that are equipped with diesel engine software that can evade emissions tests. The problem might be far more complicated than simply creating a single solution for all of them, though. According to Automotive News citing Reuters, two remedies to cover different NOx-reducing systems could be necessary, and both potentially affect performance. Earlier examples of the EA 189 diesel engine used a lean NOx trap to reduce the harmful material coming from the tailpipe. According to experts in the Automotive News report, a software update might allow the engines to achieve compliance, but that could affect fuel economy. VW already tried this route once before the scandal came to light, but tests by the California Air Resources Board still showed the figures were too high. Later, some of the 2.0 TDI engines began using Selective Catalytic Reduction that reduced NOx by injecting a urea solution into the exhaust stream. According to Automotive News, a software update for this equipment might increase the amount of the substance used. Not only would that mean topping up the fluid more often, but there still could be some reduction in fuel economy. But, since the 2-liter, 4-cylinder TDI engine that sits inside the diesel vehicles first mentioned as being affected by the issue in the US don't have a urea treatment system, VW would need to install them into these cars. VW still hasn't officially outlined its solution (or solutions) to the emissions issue but is expected to soon. The automaker's long-term evasion of regulations with these diesel engines pumped vast quantities of additional NOx into the air. The substance is known to be linked with smog and acid rain. The US Department of Justice is already beginning an investigation into the company, and politicians are pushing for harsh punishments.
