diesel cars

  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.

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.

With the roaring applause still ringing from the recent debuts of the new Silverado 1500 , Tahoe and Suburban , Chevy has also revealed a pretty heavy revamp for the 2015 HD trucks.

It seems the welcome reception to all the other new bow-tie trucks means that the 2014 model year will be very short: GM pushed up the HD release so that all the factories can start gearing up for the hugely-improved 2015 model year.

The Silverado HD’s updates are actually much deeper than a facelift, with the largest changes coming from the way the truck body is mounted to the chassis. Chevrolet is using a new type of welding process that is claimed to bring large increases in all rigidity measurements, cabin quietness and ride comfort.

The new nose looks pretty great, actually. Chevy ’s truck styling really seems to be very sharp these days. Projector beam lamps update the nose nicely, and a very dramatic chrome grille has far more shaping and structure to its surfaces.

Improvements to cooling and aerodynamics are hoped to increase highway fuel economy, where these big trucks really start to chug whatever fuel they are using at anything over 65 mph.

Drag is a real issue for these machines, and any HD owner will tell you that an 80 mph cruise with a trailer can switch the usual miles per gallon into gallons per mile.

Other changes include a totally-redesigned cabin, seats, infotainment and the whole vehicle’s electronic architecture. Under the hood, the engines are carryover but have a new engine management that integrates all the towing and stability safety features into its work flow.

What this boils down to for buyers is better economy, higher payload and towing stats, and a cruise control that now claims to be able to maintain a set speed even with a heavy trailer out back. Previous cruise controls for many cars will pop off and fail to keep a speed if doing so might make the engine stall.

So it is truck-a-palooza at Chevrolet this winter. Are buyers swayed by the new looks and vastly superior cabin?

Comfort, safety, durability and power are the key reasons for upgrading to these heavier pickups from the lighter-duty Silverado that is all new for 2014 . Even while the new model has projector beam headlights and some extra cabin tech, the 2500HD and 3500HD Silverado’s continue with only detail tweaks for 2014.

These updates include a new standard final drive ratio that boosts tow ratings by 4,500 pounds across the board, and a bi-fuel option that can run on normal gasoline or clean and affordable natural gas at the flip of a switch.

Chevy packs quite a bit more strength into these $30,000 to $50,000 2500 HD and 2500 HD trucks than their fierce cross-town rivals from Ford’s F-Series Super Duty and the Ram Heavy Duty choices.

These trucks have the rock-solid capabilities that would have required heavy and specialized machinery even a few decades ago.

Two quite unique buyer groups exist for these Texas-sized pickup trucks: people using the HD trucks to earn a living, and people who are so rich that they need to be able to transport all their toys to the cabin - at the same time. 10,000-plus tow maximum’s and fifth-wheel trailer hitches available, the Chevrolet Silverado HD trucks are only of the only ways to move a family of five, a large boat, jet ski’s and ATVs all in one trip.

These days, the Silverado HD series will happily get filthy doing the dirty work from dawn to dusk, but it must also deliver far more friendly service during the off hours. This is the real challenge for all pickup trucks, and the Chevrolet Silverado 2500HD and 3500HD models are the last bastion of (at times) crude manners and a DuraMax exhaust drum wider than a telephone pole.

All this while hauling its drivers and their families in comfort and safety that still seems unimaginable at times for these big work trucks. Is the aging 2014 Silverado HD still up to the task in the face of a revised 2014 Ram Heavy Duty with an air suspension in back? How about versus the ever-popular Ford F-Series Super Duty and its huge cabin space?
