Two decades’ worth of Volkswagen Group vehicles are vulnerable to a simple, cheap hack that can unlock their doors.

A research paper released this week (first reported by Wired) describes how multiple Volkswagen, Audi, Seat and Skoda models built since 1995 can be unlocked using a handmade radio that copies key fob signals.

The Italian coachbuilding industry took a massive hit during the latest global recession. Storied marques such as Bertone disappeared into the ether under the crushing pressures of debt and a shifting automotive industry that had become more self-sufficient.

Now, some eight years after the beginning of the recession, the Italian coachbuilding industry is making a fantastic comeback — albeit, at a cost.

Audi sales in the United States grew 14%, or 1852 units, in September 2014, the first full month of sales for the Q3, Audi’s new entry-level crossover.

The Q3, along with Audi’s entry-level sedan, the A3, contributed 3425 more sales to the Audi ledger than they did a year ago, when the Q3 didn’t exist in America and the A3 hatchback (seven September 2013 sales) was on its way out.

The maths are simple. Non-A3/Q3 sales at Audi dropped 12% in September, a loss of 1573 units.

This isn’t exactly trouble in paradise. Month after month after month, Audi dealers in the United States are selling more cars. The current streak of year-over-year monthly sales increases dates back to January 2011.

Volkswagen Group’s goal of selling 10 million units annually may come as soon as the end of 2014, with Porsche leading the way in operating profitability.

Following the departure of Volkswagen Group of America CEO Jonathan Browning, VW of America has disclosed that another high executive will be leaving the company. According to Automotive News, Frank Trivieri, the Volkswagen brand’s executive vice president of sales since 2011 is no apparently history at the company. Trivieri, 51, leaves VW following a year in which VW’s U.S. sales declined 7% in a market that grew by 8%, amid reports of strained relationships with American dealers.

The United States was supposed to be an important part of the Volkswagen Group becoming the world’s biggest automaker by 2018, with sales of 800,000 units in the U.S. by then, but it’s finding the U.S. market a tough nut to crack. “We understand Europe, we understand China and we understand Brazil,” VW Chairman Ferdinand Piech told Bloomberg this month. “But we only understand the United States to a certain degree so far.”

Volkswagen intends to sell a subcompact SUV in the United States by 2016 and there is a strong possibility that the vehicle will be assembled at VW’s Chattanooga, Tennessee facility. Marc Trahan, executive vice president of VW of America, told reporters at an Automotive Press Association event in Detroit.

The Volkswagen Group announced that global July sales for VW branded vehicles were down half a percent from last year, to 466,100. Reuters reported that July joins March 2013 as the second monthly decline this year.
