Audi recalling 70k TDI models worldwide over braking problem

Audi is issuing a recall covering some 70,000 vehicles worldwide, due to problems with their brake boosters. According to Automotive News Europe, diesel-powered examples of the A4, A5, A6, A7 and Q7 are all being called back due to this issue.
The report indicates that while the brakes in these vehicles still function, the enhancing power from the booster may fail due to a possible leaky membrane.
All of the affected vehicles are powered by the 3.0-liter TDI turbodiesel V6, and were built between March and December of 2012. It is unclear as of this writing how many of these vehicles are in the States, though remember, US customers are not privy to 3.0 TDI examples of the A4 or A5. Autoblog has reached out to Audi for specific numbers, and we'll update this space when we hear more.

It's a good time to get a great deal on a new sports car

Anyone who regularly follows our reporting on the biggest discounts on new cars already knows that the largest sums of money are generally lopped off the sticker prices of the priciest vehicles. It just makes sense. The formula holds true in April, with the 2020 Audi R8 leading the way. It's important to note that the Audi R8 comes in both coupe and convertible flavors and, despite coming standard with a V10 engine, multiple power levels. On average, customers are paying $18,551 less than the R8's $191,136 sticker price. That's nearly 10% off, with the average out-the-door price hovering at $172,585. Up next is the 2020 BMW M8, a vehicle we've grown used to seeing on this list. It's sold in hardtop, convertible and four-door Gran Coupe body styles, and when you average out all of its transactions, buyers are scoring discounts of $16,930 with an average transaction price of $139,891. That's 10.8% off the German car's sticker price. Another familiar face is in third place this month. The 2020 Acura NSX often leads the biggest-discounts list, and even though it's fallen a bit behind in the savings race, we doubt buyers who see $16,675 cut off the sticker are complaining. With an average transaction price of $143,013, that discount equals a savings of 10.4%.
