  The diesel engine is a type of internal combustion engine; more specifically, it is a compression ignition engine, in which the fuel is ignited by being suddenly exposed to the high temperature and pressure of a compressed gas, rather than by a separate source of ignition, such as a spark plug, as is the case in of the gasoline engine.

As the cheapest coupe Audi sells, the A5 is designed to bring a seductive two-door into an affordable price bracket. Now Audi looks to add even more value to that bargain basement price with its new “ultra” line of TDI equipped cars.

The Volkswagen family of turbocharged diesel engines are already some of the best when it comes to balancing fuel economy and performance, so it makes sense to see that expertise leveraged. The new ultra models are equipped with a new 2.0-liter TDI engine that is available in three levels of power output: 136 horsepower, 163 horsepower and 190 horsepower. If those numbers seem low, don’t worry. These engines pack tons of torque, so at lower speeds they still have plenty of thrust.

The A5 Ultra comes powered exclusively by the 163-horsepower version of this new engine. This engine configuration lays out an absurd 295 pound-feet of twist, and it is sold with a special six-speed manual transmission with taller final gears for improved economy. Audi is claiming a fuel economy rating 56 mpg combined on the EU scale, and top speed sits at 140 mph.

As you can probably guess from the manual-only designation, this car is not currently slated for a U.S. release. We reached out to Audi on the possibility of bringing the “ultra” models to U.S. shores, and John Shilling, Manager of Product Communications at Audi, said there are "No plans in the U.S. for that version at this time."

The sales market of executive limousines has been slowly increasing over the last several years. These extra-long sedans provide unsurpassed comfort, technology and refinement. Formerly the sole domain of rear-wheel drive German sedans with huge cylinder counts, the market has seen quite a shakeup over the last few years. Hyundai is trying to steal sales with the Equus , and companies like Audi have released more fuel efficient, diesel-powered versions of its A8L , and nearly every competitor now offers an AWD variant.

BMW is looking to take eyes away from the competition with its own fuel-efficient, all-weather model. The newly announced 740Ld xDrive combines a fuel-sipping diesel engine with the xDrive AWD system and crams it all under the sheetmetal of BMW’s biggest car.

Is this the winning combination that BMW needs to keep from hemorrhaging buyers to competitors like Hyundai, Jaguar and Audi? We have all the details below to help you decide for yourself.

Diesel-powered cars are gaining ground in the United States lately with both Volkswagen and Audi introducing new models into the market. Mazda is looking to join the fray of consumer diesel model with its Mazda6 sedan.

If the idea of parking an oil-burning "zoom zoom" sedan in your garage sounds great you need to put on your hat of patience. Mazda has just announced that the Skyactiv-D equipped Mazda6 has been delayed.

The car has not been delayed due to emissions testing, rather Mazda feels the car doesn’t have quite the right driving dynamic. In its own words words the diesel Mazda6 needs to be tweaked to provide "the right balance between fuel-economy and Mazda-appropriate driving performance."

While it makes us a little sad that Mazda has delayed the introduction of this engine to the US market again, we can’t help but appreciate the desire to deliver the best-driving product they can.

With how much the gasoline-powered 2014 Mazda6 impressed us, it’s no surprise that Mazda is refusing to deliver a sub-par product.

Audi R20

In 2012, rumors swirled that Audi was working on a production version for the R8 V12 TDI concept that it unveiled at the 2008 Detroit Auto Show. Since then this model was up and down so many times that we ran out of fingers and toes to count it on on.

During a recent interview at the 2014 Detroit Auto Show, Audi technical chief Ulrich Hackenberg announced that such a model — rumored to be called R20 — was put to rest once again and that it was "an interesting idea but not a priority."

Even though this model is on the shelf for now, Audi really needs to develop a new supercar, as the R8 is starting to get a little wrinkly and a new generation R8 likely wouldn’t hold a candle to all of the recently launched hybrid supercars. In fact, even BMW finally decided to release the i8 after years of ups and downs, and we’re sure that Audi will shortly follow its steps.

Now its true that Audi also has in its plans the R8 e-tron , which has also seen its fair share of ups and downs, so maybe the restarting of the R8 e-tron talks at Audi headquarters sparked the shelving of the diesel-electric supercar.

Hackenberg also said that instead of the diesel-electric supercar, Audi will focus on developing a sub-2,200-pound version of the future TT . This model will likely be high-tech and perform well, but it definitely won’t satisfy the cravings of supercar junkies.

Mazda is preparing to enter the only diesel -powered prototype racer in the new Tudor United SportsCar Championship.

Diesel-powered racers have dominated endurance racing in the last decade. The 24 Hours of Le Mans has been won by an oil-burner for eight-years running. Even the FIA World Endurance Championship races have seen a diesel powered car on the podium at every single race.

Mazda is the only Japanese manufacture to win overall at Le Mans when it took the podium in 1991 with its rotary-powered 787B. Mazda is hoping that it can pull a page from Audi ’s book and is looking to diesel power to try and dominate the prototype class in the new TUDOR racing series.

We have all the details on this ambitious new race car and who will be driving it at Daytona later this month.

The 2014 Ram Heavy Duty is heavily revised with new air suspension options, an all-new interior, and a fifth-wheel trailer towing option that allows these huge trucks to hitch a trailer right into the bed of the pickup truck.

The Heavy Duty Ram line also brings a mild exterior refresh with the projector-beam lights on posh trims like the Laramie test truck.

A quick spin was enough to have me looking for poundage to haul somewhere, maybe a friend who likes to ride dressage horses competitively?

Sadly, not enough time to test the limits of this tall workhorse by towing some show ponies out back.

This all-new 2014 Mega Crew Cummins 2500 is the big chief of the Ram family, with over 800 pound-feet of torque and tow ratings that would make a tractor trailer blush with embarrassment. For a non-truck-guy, the 2500 Ram is generally thought of as the 20,000-pound trailer max — in the right settings.

The 3500 Ram is now in a class of one with a 30,000-pound towing max, again with the right option boxes ticked.

With base pricing just below $30,000, how does the Ram HD line compare with the best-sellers from Ford and Chevy ?

As part of One Ford , the company will launch a new crossover for sale in late 2014 that is tailored to the universal global preferences of value and style.

The new global SUV will be revealed to the world media at the 2013 LA Auto Show before going on sale almost globally by 2015. So why all the mystery about what the new world-wise five-seat crossover will be?

It is the 2015 Edge, scheduled for display in LA as lightly dressed as a concept car before going on sale in Summer 2014 all over the world.

The current Ford SUV range in Europe consists of the EcoSport and the Kuga that can be categorized as crossovers unlike the new Ford Edge that is planned for launch next year.

The EcoSport and Kuga began life as a "global models" made specifically for certain target markets.

The rest of the Ford model range comprises of hatchbacks, sedans and MPVs that have been popular with folks in continental Europe.

Seeing a line of pristine Carrera White Audi ’s from across the paddock at Autobahn Country Club was almost enough to make a guy start jogging to get the first seat time. The brand-new S Q5 was on the pre-event list of attendees, and the new grille finish of the Q5 in brilliant white was very promising.

Within closer range, the “TDI clean diesel” script was visible on the side of almost all ten Audi ’s on offer for the car writers to sample. The A7 and A8 were common sights leaving the club gates, but at least one car writer was mildly disappointed.

Not only was the S Q5 not present, but diesel engines all around? Eek. One bright spot was visible: a gigantic white Q7 with some snazzy fender flares on anthracite grey alloys.

Also... a diesel, but this was more TopSpeed style.

A quick blast up to my gravel road photo spot was enough time to fall head-over-heels for the big Q7, even as its replacement is firmly on the horizon for 2014 or 2015.

This Audi is a creamy beast with torque for days even in the 3.0-liter TDI specification. The real clue to its fresher-than-average looks is the S-line trim worn by the tester, which brings along a host of sporty programming options and décor inside as well.

When a Cayenne is too bouncy, and an Escalade is too soft, look no farther than the Q7 TDI S-line for a seven seats and a ride that is ’juuusst riight’.

Kahn Design just launched a hot body upgrade for the diesel Porsche Cayenne , bringing some of its chic mods to a truck besides the Range Rovers that are its bread and butter.

Kahn favors a huge revamp outside and in. The exterior and the interior look of the Cayenne were updated, but the base 3.0-liter, V-6 diesel is quite enough. It delivers a total of 240 horsepower and 406 pound-feet of torque, while delivering range and tax options to people without the Turbo S.

The exterior look however, is deeply revised and transforms even the Cayenne Diesel into a mean and powerful SUV.

New sports lowered suspension springs bring the car closer to be road, while the privacy glass ensures a the best privacy behind the wheel. Numerous Kahn logos placed on the wing shields and tailgate remind you this is no ordinary Cayenne.

The arrival of a diesel engine in the luxurious and easy-driving 2014 Ram 1500 pickup is huge news. Until this point, diesel engines for all truck lines have been restricted to just 2500 and 3500 models.

Ford and Chevy continue without a small diesel engine in their light trucks, and are about to feel the hurt from the new 2014 Ram 1500 EcoDiesel.

As much as car buyers traditionally loathe the idea of diesel engines, truck buyers adore it.

Under the chrome Ram hood, the 3.0-liter, V-6 diesel option even delivered a (momentary) 36 mpg via the standard eight-speed automatic during a light cruise on the test route. But that is not even the best part.

The Ram EcoDiesel packs all the benefits of 25-mpg-plus highway efficiency, but none of the typical diesel engine noise or the driving dynamics of an 18-wheeler. This is a machine whose huge torque reserves and lighter front end join forces to make a smooth, quiet and nimble truck. All that comfort on the air springs front and rear has virtually no major tradeoff in the capabilities tallies versus the F-150 or Silverado .

While both of those leading trucks — Ford F-150 and Chevy Silverado — are also quite refined in the drivetrain these days, none offer the absolutely S-Class -rivaling smoothness of the Ram 1500 Laramie over bumps.

Un-laden half-ton trucks might have smooth engines, but are still a pitter-patter of suspension clatter in back on good sunny days. On bad snowy or rainy days, that inherent over-sprung feel can become downright treacherous over mid-corner bumps.

Jittery and gas-guzzling pickups are starting to feel mighty obsolete in direct comparison to the swanky new Ram EcoDiesel.
