  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.

The Ram truck has been around since its nameplate was officially used on the 1981 Dodge pickup. Dodge trucks dating back to 1933 were known for their ram hood ornament, so the mascot went from decoration to the trucks’ name. Big news happened again in 2010 when the Fiat Chrysler Group moved the Ram lineup outside the Dodge umbrella, making the Ram its own brand. Now in its fourth generation, the Ram truck is breaking ground on uncharted territory. That uncharted ground includes innovations like dumping the traditional leaf-spring rear suspension design in favor of a smoother-riding, five-link with coil springs and introducing the industry’s first V-6 turbo-diesel in a half-ton package. The diesel aspect has garnered the Ram some notable attention from both the auto industry and the truck-buying public.

In fact, more than 8,000 EcoDiesel trucks were ordered by Ram dealers in the first weekend the books opened — a number than represents nearly half of the Ram 1500’s normal monthly production run. Sin Sin ce that February weekend in 2014, Ram EcoDiesel sales have exceeded the automaker’s expectations and have contributed to Ram’s overall sales increase over last year.

So what’s the big deal about a diesel, you ask? Well, I squeezed 33 miles per gallon out of my Ram 1500 EcoDiesel tester I recently had. Sure, that was with me babying the throttle down the highway, but by the week’s end, the dash still showed an average of over 24 mpg. That’s the big deal. Not to mention my tester was equipped to pull 9,200 pounds at the hitch and haul an impressive 1,620 pounds in the bed.

Famous for dropping more horsepower and torque in nearly every available Volvo model, ranging from the small C30 hatch to the V60 wagon, Polestar just added a new vehicle to its high-performance lineup. This time around, the Swedes got a hold of Volvo’s V60 D6 Plug-in Hybrid wagon, turning it into a more powerful, yet still fuel efficient vehicle. Unlike other Polestar-tweaked Volvos, the hybrid wagon comes with minor, barely-noticeable exterior changes. On the flip-side, the powertrain updates are obvious enough to to make the package appealing to those in need of more horsepower and torque.

Polestar’s major achievement with the V60 D6 Plug-In Hybrid is that, although the wagon is slightly more powerful and quicker, mileage and CO2 emissions remain the same. That’s just about any driver’s dream and it says a lot about the company’s vast experience with Volvo engines. As expected, Polestar only touched the vehicle’s diesel engine, leaving the electric motor in its stock form. Read on to find out why the V60 D6 is the most powerful diesel model wearing a Volvo badge.

The Volkswagen Golf has succeeded in ways very few of its contemporaries have. It’s in its seventh generation for crying out loud! That’s more than what other models can say for themselves. Ever since it was released in 1974, the Golf has built a reputation as the godfather of the modern-day sports hatch. But even with its age, the Golf is still a strong presence in the hatchback market, so much so that the model is still turning heads wherever it goes. The 2015 Golf TDI is the latest in a series of new Golf models that are now available in the market. Yes, it’s got a diesel engine but it’s a new diesel engine. That counts for something.

It was also the recipient of aesthetic tweaks that makes its design fit for the times. Some might even say that the Golf looks better than ever before, which is about as big of a compliment as you can give to the hatch that most people believe blazed the trail for its kind.

It’s been a good 2014 for Audi . The company is on pace to sell 1.6 million cars this year, a record-breaking number that has come closer and closer to threatening BMW ’s top sales numbers. But Audi isn’t just settling for the sales title. It also wants to continue to be on the cutting edge of innovation, something Audi boss Rupert Stadler brushed on when he announced plans to launch RS-badged high-performance diesel models in the future, possibly as soon as the end of the decade.

The company is optimistic that it already has the applications to transition the technology from concept form into production. Remember, the RS5 TDI concept showed that it was possible to slap an e-turbo-diesel engine into an Audi without compromising the car’s performance capabilities.

Stadler understands that the key in achieving that goal is to take a step-by-step process on piecing together the tools and technology needed to make it work on a production model.

You can count on Audi to always be at the forefront of innovation. The German automaker thrives on being in that position, and when you give it incentive to succeed, you can bet that it’s going to pull out all the stops to make it happen.

The trendy and gorgeous Audi A7 is receiving a facelift for 2015, and with it comes a new 3.0 TDI Ultra model that pushes the turbo-diesel to new heights of efficiency and cleanliness. Introduced in 2012 to compete with the Mercedes-Benz CLS-Class , the A7 was an immediate hit. Combining arguably the best styling in the segment, a sumptuous interior, and excellent performance, it’s no wonder this car was so well-received. It wasn’t just consumers who were impressed; the A7 won several awards, including the Automobile Magazine 2012 Car of the Year Award. Autoweek featured the A7 in its "Best of the Best" feature, and, in general The A7 has been at or near the top in virtually every comparison test since its arrival on the U.S. scene.

The TDI version, introduced here just this year, has also been praised. In a recent road test of the 2014 Audi A7 TDI, Car and Driver exclaimed themselves "drunk on diesel." They were particularly enamored with the TDI’s endless 428 pound-feet of torque and excellent efficiency, with a 30 mpg combined rating.

Not one to rest on its laurels, however, Audi is giving the A7 TDI a new Ultra version to help reduce consumption and emissions even more.

Diesels are very popular these days. They perform well, with stump-pulling torque, and are vastly more efficient than their gasoline-powered counterparts. Whereas a few decades ago a diesel engine would be written off as a smokey, slow oil-burners, these days the demand is very high, and former negative diesel traits have all been eliminated due to the advanced technology of today.

Perhaps the most impressive diesel offerings come from the German manufacturers. BMW , Audi , and Mercedes all offer several diesel engines that are every bit as desirable — if not more — as their respective gasoline versions.

Audi has an innovative new spin on the turbo-diesel with itsA6 . It is still a mono-turbo setup, but with an electric turbo chiming in to help out at lower revs. This innovative design will virtually eliminate turbo lag and provide even more oomph off the line than diesels are already famous for.

How does it work?

Still relatively new, the Audi A7 Sportback rides on Volkswagen Group’s MLB platform and first drove the streets of America in 2012. That MLB platform also underpins the A4 , A5 , A6 , A8 , and even the Q5 and Porsche Macan . Needless to day, it’s a popular building block for Volkswagen vehicles. Besides its underpinnings, the A7 Sportback comes with a pair of V-6 engines. First up is the 3.0-liter TFSI supercharged gasoline engine making 310 horsepower and 325 pound-feet of torque. While it’s a great engine, fans of oil-burners will love the 3.0-liter TDI turbo diesel also available in the A7. Audi’s rich history of TDI engines turns a quarter century this year, and to celebrate, the German automaker is offering the A7 Sportback TDI Competition model — a hopped-up version of the A7 TDI.

The twin-turbocharged, clean-diesel gets meatier camshafts that help generate an additional seven horsepower, bringing the total to 326 ponies. The 3.0-liter TDI enjoys a maximum torque output of 479 pound-feet between 1,400 and 2,800 rpm. These changes don’t kill the A7 Sportback’s fuel economy either, as it still returns over 38 mpg. Get hard on the throttle, however, and the TDI’s computer will temporarily increase turbo boost, squeezing another 20 horsepower out of the mill, making its maximum output 346 horses.

There are plenty of other changes around the A7 Sportback TDI Competition package besides the extra oomph. Click on past the jump for the full rundown of all the updated features and creature comforts within Audi’s latest A7 TDI.

There are tons of rumors floating around about the upcoming second generation of Audi R8 . Everything from five-cylinder engines to wireless charging capabilities for the R8 e-tron are being talked about for the car’s 2016 entrance into the U.S. market. Well, here’s one more for the rumor mill: a TDI version.

The idea may not be new, but it seems to be gaining some credence for the upcoming model. Volkswagen Group executive Ferdinand Piëch is reportedly itching to have a turbo-diesel engine under the R8’s rear glass. While a TDI-powered R8 won’t be likely until at least 2017, the possibility is still present.

What’s more, Volkswagen Group has two TDI options to choose from. The first would be to simply use the existing 4.0-liter V-8 TDI but spiced up with more horsepower and torque. The other option would be to utilize the 5.0-liter V-10 TDI Audi is currently developing for future Bentley models.

While we’ve got no firm estimates on horsepower and torque outputs for the V-10 TDI, we can always guess. Remember the V-10 turbo-diesel Volkswagen stuffed under the hood of its Touareg SUV in the late 2000s? With twin turbochargers spooling up, it made 310 horsepower and a stump-pulling 553 pound-feet of torque. Imagine what today’s clean-diesel technology and computer control systems could do for a performance-oriented V-10 TDI. Perhaps 500 horses and 800 pound-feet of torque? We can always hope.

While the TDI R8 remains a distant model at this point, we can count on some high-performance gasoline engines to power the mid-engine supercar . Expect the V-8 and gasoline V-10 to carry over, along with some nice output updates.

It’s been six years since Jaguar and Land Rover left the Ford ownership umbrella, but the British automakers are still using Ford-derived engines they inherited back in the late 1990s. That’s about to change though, as the Brits are set to introduce a new family of efficient powerplants. Dubbed Ingenium, these new engines promise to deliver a compelling combination of power, efficiency, and low CO2 emissions in many shapes and sizes.

Built in-house at the company’s new engine facility in Wolverhampton, England, the first version of the modular unit family is set to debut in the upcoming Jaguar XE and find its way into the Land Rover Discovery a few months after that. The Ingenium family will include both gasoline and diesel variants with turbochargers attached to them. As with all modular engines, JLR’s new powerplants will share many internals and calibration strategies, enabling the company to raise quality and simplify manufacturing.

Looks like Jaguar Land Rover is finally growing up!

When it comes to press cars and review cars, there are few machines I know more intimately than the 2014 Audi A6 TDI . Last year I joined a collection of fellow lunatics and set out on a 48-hour cannonball run from LA to New York City to test out Audi’s new 3.0-liter V-6 diesel engine, and really test its real-world fuel economy. After 46 hours and nearly 3,000 miles, I had spent several hours in every seat, tried to eat, sleep, and work inside of its wood-filled interior, and used almost every gadget it contained to keep myself entertained.

I have made lots of big road trips in lots of cars including the Nissan GT-R and Porsche Cayman S , but this was a whole new experience.

After such an experience, I have lots of things to say about Audi’s full-size luxury sedan . From equipment and pricing to performance and fuel economy, the Audi made major impressions. But where all those impressions good, would I do the trip again, and do I think it’s a car worth spending money on?

All your answers await after the break.
