Mercedes-Benz is digging in and putting more features into its redesigned flagship S-Class sedan. This is not just another ultra-luxury sedan. Mercedes believes the all new S-Class, packed with cutting edge technology, will set the tone for the entire line-up of Mercedes models.

More importantly, the changes are designed to keep the S-Class on top of the ultra-luxury sedan market—models sell between $80,000 and $130,000.

"This S-Class is a huge amount better [than the previous model] in all aspect, so we are very confident about the position of this vehicle regardless of the competitors," said Dieter Zetsche, Mercedes-Benz Cars CEO and Chairman of Daimler.

Zetsche was all smiles at the official unveiling of the S-Class in Hamburg, Germany. The event was held at the Airbus A380 delivery center. As part of the event, the new S-Class was driven across the runway before it rolled into a pavilion where Zetsche talked about the luxury cars new features.

Some of the most popular small SUVs have failed crash tests that simulate a common and deadly front end collision.

"These are troubling results," said Joe Nolan with the Insurance Institute for Highway Safety. "These small SUV's are very popular and for the most part pretty safe, but with these tests most of them did not do well."

For the first time the Insurance Institute for Highway Safety conducted small overlap crash tests with small SUV's. Eleven of the thirteen models tested received marginal or poor ratings.

An increase in auto repossessions due to borrowers defaulting on their car loans is raising new questions about whether the auto industry is going too far selling new cars and trucks to those with subprime credit records.

According to Experian Automotive, the percentage of auto repos in the first quarter jumped 16.9 percent, and the average charge-off for bad loans jumped more than $600 to $7,401.

Combined the two figures suggest dealers and lenders are selling cars to those who are not a good credit risk, but not everyone sees it that way.

As used car deals go, this is one to make you think twice. Used Fisker Karmas, which sold for $103,000 just a year ago as new models, are now being sold for roughly half price. In some cases, those trying to sell the luxury extended-range electric car on eBay cannot even get bids above $50,000.

Just ask Bill Michlin, a dealer with the Fields Auto Group in the Chicago suburb of Glencoe. He just wrapped up an eBay auction for a 2012 EcoChic version of the Karma with a top bid of $45,100. "I had 2,000 look at that car on eBay," he said. "We didn't sell it because it didn't meet the minimum reserve bid, but it will eventually."

Used Fiskers selling for 50 cents on the dollar is the latest example of how far the electric car company has fallen over the last four years. A company once touted as an example of how start-up automakers were changing the auto industry now owes the federal government $192 million and is no longer building new models.

The New DeLorean?

Thirty years after the DeLorean came to symbolize a futuristic car that failed to take off in huge numbers, the Fisker Karma is now viewed in a similar light. Approximately 2,500 Karmas were built in 2011 and 2012. But the Karma never became more than a niche luxury model. The electric car was rated by the EPA to get the equivalent of 52 mpg and was panned by Consumer Reports after the Karma model it was testing actually broke down.

After years of ignoring the luxury pick-up market, the folks running Chevrolet have had a change of heart. The company is extending its pick-up lineup with the new Silverado High Country.

The luxury truck hits showrooms this fall and in my opinion, it is long overdue.

The luxury market is a relatively small niche within the pick-up market, but for years Chevy ignored it.

For GM, the GMC Sierra Denali was the company's competitor in the upscale pick-up market—and while it's a fine truck you have to wonder why Chevy never came out with a high-end model of its own. Now, that is finally changing.

One month after rolling out a lease-to-own financing program that generated plenty of attention and bad reviews, Tesla is amending the program.

"When we did our first finance announcement about a month ago, we didn't get it quite right," said CEO Elon Musk during a conference call announcing the revisions. "We listened to a lot of valid criticism from journalists and customers so we have tried to take corrective action and make it a lot better."

These are the two primary changes to Tesla's financing program:

• Higher Guaranteed Residual Value

  Tesla is guaranteeing those who lease a Model S will be able to return the car after three years with a residual value of at least 50% of its sticker price, versus the 43% the company announced last month.

  And it could go higher than 50%: Tesla said the Model S residual value will be greater than the three-year average of BMW, Audi, Mercedes and Jaguar. So if those brands' average residual value climbs above 50%, Tesla will match it.

  "What we are saying to people is you are going to get 20% more cash for your car in three years than our prior guarantee, so that is a pretty big jump," Musk said.

• Longer Financing Terms

  Tesla is extending the length of the lease-to-own contracts to 72 months from 63. This move is not surprising, as the average length of all auto loans is now 65 months, and six-year loans are no longer considered unusual.

  As a result of the extended terms, the out-of-pocket cost for a Model S buyer will drop to $580, according to Tesla. That estimate is based on the amount of money Tesla projects owners will save by not buying gas.

You know this is the kind of quarter General Motors CEO Dan Akerson has been waiting for. The automaker reported better than expected profitability in the U.S. and China and a lower than expected loss in Europe.

Akerson is not the type of CEO to sound giddy on earnings conference calls and that didn't change on Thursday. Still, you could sense his pleasure when he opened the call saying, "We are systematically and successfully implementing our plan around the world."

Ford, facing greater demand for its F-Series trucks, is adding a third shift and hiring more than a thousand new workers at its final assembly plant in Claycomo, Missouri where the popular F-150 pick-up is built, the auto maker said.

The move is part of Ford adding a total of 2,000 jobs and expanding capacity at the plant outside of Kansas City, Missouri.

"We are going to step up operations at Kansas City to ensure we have enough trucks to meet customer demand," said Joe Hinrichs, Ford's Americas President.

Call this the long overdue Spring sales surge for the pick-up truck.

It may not be sexy, but the importance for automakers and the U.S. economy cannot be overstated.

"Housing is beginning to improve, and that's fueling our pick-up sales," said Kurt McNeil, Vice President of U.S. Sales for General Motors.

In April, the big 3 all saw big sales for their pick-ups.

• Ram Trucks up 49%
  
• Ford F-Series up 24%
  
• GM Pick-ups up 23%

After posting strong profit growth quarter after quarter for much of the last two years, Chrysler saw earnings growth slow last quarter.

The lower profit was expected as Chrysler shipped fewer vehicles, handled higher costs due to the launch of new models, and saw its mix of sales shift more toward less profitable cars.
