The engine's electronic system detects that the car is undergoing an emissions test. But how do these tests actually work? The emissions testing system that's used today dates back to the 1980s.The auto industry is working to keep the system just as it is, because it gives them lots of opportunity to influence the test results. Those results often vary widely from the ones that actual motorists get on the road. What do consumers have to say about all this? We talk to experts to find out how these tests should be reformed, so that they provide more accurate figures. Vintage! Bentley 8 LitreBlair Castle in the Scottish Highlands provides the perfect backdrop for a tour in a very special antique car. At close to 6 meters in length, the Bentley 8 Litre was the biggest passenger car made in Britain in its day. Between 1930 and 1932, exactly 100 of the handcrafted models were produced.While previous Bentleys were famous for the roar of their motorsport engines, the 8 Litre is more of a strong, silent type. And inside the Bentley has the genteel flair of a British gentleman's club -- it's a symphony of wood and leather.
