For Mercedes-Benz lovers in the Allentown area, Knopf Automotive is dedicated to keeping you informed regarding the latest ways to interact with the luxury vehicle lineup through technology. One way this can be done is by using apps from the iTunes store for iPad devices. We've found four apps that we believe all prospective and current Mercedes-Benz drivers should know about.

The Porsche Cayenne combines the unique blend of unprecedented luxury and performance available in all new Porsche models, while offering all one could hope for in an all-wheel drive SUV, too. That doesn't mean German automaker has finished perfecting and molding the SUV, however, as it recently introduced special options available on the Cayenne GTS trim.

The popular social networking site Twitter is fast-becoming a fun and creative way to hold a contest, so Audi decided to utilize the platform to give drivers a day behind the wheel out the 2012 Audi R8. All Twitter users had to do was tweet the @Audi account, telling them in 140 characters or less how much they'd like to spend the day in the luxury car. To get noticed, users had to drop the tag #WantAnR8 in their posts.

At Knopf Automotive, we like to think we know a thing or two about luxury and exotic cars. Of course, we also know that there are more than a few third-party automotive gurus who are quite knowledgeable on the subject as well.

If you are the proud owner of a new iPhone 4S, then there's never been a better time to consider Mercedes-Benz for your automotive needs. And why would that be?

And we here at Knopf Automotive can't wait to experience the incredible utility that this adds…

While there's no denying that the Audi R8 is a speed machine unlike any other, we'll admit that there are times when we wish it were possible to bring more than one passenger along for the ride. After all, the thrilling performance of the R8 is something that everyone deserves to experience at least once in their life. One limousine company based in the UK seems to have just the answer, and we…

Here at Knopf Automotive, we love celebrating the milestones of our favorite German automakers. They come in all forms, and are often tributes to the quality, performance, and style that makes them stand out amongst the competition. The latest one? That would be from the Porsche Cayenne celebrating 100,000 models produced so far!

This latest achievement in the new Porsche lineup couldn't have come at a better time either, as it lines up…

We here at Knopf Automotive know the dangers of driving at night. Drivers experience reduced visibility, delayed reaction time, and a greater chance for nocturnal animals to run out into the road. It goes without saying, of course, that a leading-edge luxury brand like Audi would do everything in its power to keep drivers safe at night.

Enter, Audi LED technology. The German automaker's LED polarized lenses offer greater calrity, consume less energy, and…

With the start of 2012, we here at Knopf Automotive can't help but look back at the last year and be amazed at the incredible success of the Mercedes-Benz brand. The iconic German automaker financed and leased a wide range of vehicles in 2011, but they were, perhaps, most successful in the Sport Utility Vehicle/Crossover Utility Vehicle market.

For those of you who are unaware, that encompasses models like the Mercedes-Benz R-Class, Mercedes-Benz?

Are you a big fan of the Audi A7? If you are, then brace yourself... Automobile magazine has recently named the full-size luxury car from Audi as the "Automobile of the Year," much to the delight of everyone at Knopf Automotive.
