  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 Mini brand was resurrected for the 2001 model year, five years after the original Cooper ceased to exist. Initially available only as a three-door hatch and two-door convertible, the new Mini quickly grew into a lineup that included the Clubman , the Countryman , the Coupe and the Paceman . The first-gen model survived for only five years, being replaced by the second-gen in 2006. In 2013, the brand new, third-generation Mini was unveiled, this time riding atop BMW ’s UKL1 platform.

Mini already debuted a brand-new diesel engine for the Cooper 5-Door , and the Brits decided to give that same oil burner to the three-door version as well. We’re talking about the 2.0-liter four-banger that generates 170 horsepower and 265 pound-feet of torque, and enables the Cooper DS to become the most powerful diesel Cooper ever created.

Of course, it’s not overly fast from naught to 62 mph, but its 7.3-second second sprint is good enough considering the hatchback claims to return up to 58 mpg on the highway. The 0-to-62 mph figure drops to 7.2 seconds when the engine is paired to the six-speed Steptronic transmission. Sporty and efficient, a recipe that fits today’s demanding market like a glove.

Unfortunately, there’s no word as to whether this nippy fuel sipper will hit U.S. shores or not, but don’t expect to find it at a dealership near you this year. On the other hand, those of you who live in the United Kingdom can order one starting July 2014.

The BMW X6 has been blurring the lines of SUV and sports car since its introduction in 2008. Things got even more strange when BMW threw a diesel engine under its hood and slapped an M badge on the side. Yes, BMW makes a diesel-powered M product. Unfortunately for those in the United States, the X6 M50d has been unobtainable. That trend sadly continues as the X6 rolls into its second generation for 2015.

The X6 can thank its second-generation upgrade to the X5, the SUV on which it’s based and shares much of its platform. For 2014, the X5 received a healthy makeover, including slightly larger dimensions for increased interior volume, a revised exterior, and a fresh interior.

The standard 2015 X6 is destined to arrive on U.S. shores likely sometime in the fourth quarter of 2014. While the M50d will be missing from our BMW lineup, our friends overseas will get to enjoy its torque-rich oil-burner. The M50d sports a straight-six construction displacing 3.0-liters and spooled up by two turbochargers. With an output of 381 horsepower and a tire-shredding 546 pound-feet of torque, the X6 M50d sprints to 62 mph in just 5.1 seconds.

Even with all that power, the 3.0-liter, I-6 diesel still sips fuel like a Prius. On the European test cycle, the SUV returns a highly-respectable 42.8 mpg! Let that soak in while you click past the jump.

It’s been 25 years since Audi launched its TDI engine, and the Germans are celebrating the milestone by introducing a diesel-powered Audi RS5 . Just a concept vehicle for now, the RS5 had its regular V-8 engine replaced by an oil-burning 3.0-liter TDI that features the company’s new electric turbo unit.

What’s so special about that, you may ask? Well, is appears that Audi somehow managed to enable its electric turbo to provide maximum torque from just 1,250 rpm. The unit basically ensures there’s no turbo lag until the regular turbos kick in at 3,000 rpm, turning the RS5 TDI Concept into a major breakthrough.

With that pesky turbo lag out of the way, the diesel RS5 is quite a performer too, needing only four seconds to accelerate from naught to 62 mph. Of course, that wouldn’t be possible without help from the 385 ponies and the 553 pound-feet of torque under the hood. Needless to say, the RS5 TDI is the fastest six-cylinder diesel vehicle ever developed within the Volkswagen Group .

But will this concept vehicle make it in to production to become the company’s first diesel RS? Unfortunately, Audi has yet to make a statement on that, but we have a hunch this new electric turbo technology will become more than just an experiment. We wouldn’t be surprised to see the RS5 TDI hop on the assembly line over the next couple of years, but, if that doesn’t happen, the electric turbo will find its way into other production cars.

With so many cars promising the world these days, British sports car brand Trident is promising something completely different with the Iceni Magna, a fastback-styled sports coupe that not only runs on a diesel engine, but also features torque multiplication technology, allowing to reach a top speed of 190 mph with a capability to cover 2,000 miles on a single tank.

Such a promise will definitely raise some eyebrows, but Trident is welcoming the curiosity because it believes it has a technology that could go a long way in redefining how automakers work on future powertrains. According to Trident, properly utilizing a car’s torque numbers to "multiply" its effectiveness improves its car’s performance and efficiency by up 20 percent. It’s a technology that Trident has patented, so it certainly has enough faith in what it’s created to take the time to secure the intellectual rights to it.

So that’s what we’re going to see on the Trident Iceni Magna. It’s got an impressive look with splashes of retro inspiration and adding to that, a powertrain technology that promises loads of speed and efficiency the likes of which we haven’t seen before.

Trident has said that availability for the model is limited and demand is pretty high, surprising for a brand that’s not that well-known. Its demand is fairly obvious by its steep starting price of £96,000, which is about $161,500 based on current exchange rates.

Volkswagen appears to be listening to the tiny, but obnoxiously loud, voices of the forum goers and automotive journalists. At this year’s New York Auto Show , they displayed this shiny new Golf SportWagen Concept with a new 2.0-liter TDI engine, three pedals and 4Motion AWD.

Hello, Beautiful.

This latest machine may have “concept” in its name, but there is very little about this car that won’t make it to production. Volkswagen has already stated it will be coming to U.S. shores as a replacement for the near ancient Jetta SportWagen. The new Golf SportWagen will provide a modern model for U.S. buyers that is underpinned by the new MQB architecture (the current Jetta SportWagen is actually still a fifth-gen car underneath).

VW has also confirmed the powertrain options will include the new 1.8-liter turbo gasoline engine and the updated 2.0-liter TDI diesel. Shifting will be accomplished by either a traditional manual transmission or a choice of automatics. What is not confirmed, and what makes this car a “concept” is that sweet 4Motion all-wheel drive system like you get in the Golf R . VW is stating that it may come, but no firm plans have been made yet.

Start those forum threads now, kids.

Citroen has made its reputation building innovative and forward-thinking cars. Since the post WWII days with the Citroen DS , the French automaker has always thought outside the box, and this C4 Cactus is no exception.

The two defining outward features are unmistakably its unique yet familiar shape and the colored, bumpy panels affixed to its sides. While they are major components in making the C4 Cactus what it is, they aren’t its only innovative or interesting qualities. Other endearing qualities can be found within as well.

The C4 Cactus’ interior looks like a cross between an IKEA and a classy men’s wardrobe boutique, with Android software running the infotainment system and gauge cluster. Materials and their overall design are high quality with a certain vogue, yet timeless attribute.

While certain things inside and out might seem expensive, Citroen’s goal was to significantly reduce the cost of ownership – and they’ve done it by a good 20 percent. Fuel savings goes a long way in saving owners money, namely its 91 mpg rating in diesel form measured on the European cycle. Weight savings also plays a huge role here. Weighing in at a mere 2,127 pounds, the Cactus is said to be much easier on its running gear, lessening the need to replace parts as often.

Citroen seems most proud of saving customers money in the area of body damage. The Cactus’ Airbump system reduces the chance of parking lot dings and minor finder bender damage with its thermoplastic polyurethane construction and air-filled pockets. Even with their purposeful nature, the Airbump panels sure make a bold statement while living up to its Cactus name.

Toyota Tundra

Note: Current generation pictured here.

It appears Toyota will be the next automaker to adopt diesel technology into its full-size truck segment. According to WardsAuto, the Tundra will be getting a V-8 diesel powerplant when its next generation debuts in 2016. What’s more, word has it Tundra’s new oil-burner will be supplied by famed diesel builder, Cummins. And not just any Cummins at that…

It will be a version of the same 5.0-liter V-8 turbodiesel that rival truck-builder Nissan has slotted to power its next-generation Titan set to debut next year. Not only is this huge news for Tundra fans, it represents uncharted territory in diesel engine sharing on the light-duty level. Truck buyers are a fiercely loyal bunch, so it will be interesting to see where exactly loyalties fall — with the truck- or engine-builder.

There’s no official word on how the Tundra’s diesel will compare to the Titan’s, which is said to be rated at “more than” 300 horsepower and 500 pound-feet of torque. The only sure thing is the certainty of some very intense engineering meetings between the three companies.

The overriding reason diesels are catching headlines these days is the need for automakers to meet the impending CAFÉ standards that are tightening up on corporate average mpg ratings. The target: a company average of 54.5 mpg by 2025. Nissan and Toyota aren’t the first to go diesel. Ram , in fact, already has their 3.0-liter V-6 EcoDiesel currently on sale in the U.S. Rated at 240 horsepower and 420 pound-feet of torque, the EcoDiesel Ram 1500 achieves a class-leading 20 mpg city/28 mpg highway.

We never bother covering 10-minute Nϋrburgring times. In fact, anything over eight minutes is not really worth our time. And we have never, nor did we ever plan to cover a Citroen AX Diesel . I mean, with just 52 horsepower, it is pretty obvious why we just have no interest in it. That said, when you combine these two typically boring topics, we suddenly become really interested.

It takes a pretty good driver to lap the `Ring in under 10 minutes in any normal car, but to do so in this 52-horsepower, bone-stock hatchback not only takes skills, but it also takes a set of gonads large enough to need their own area code. Well, this fine gentleman must have put his set in the trunk, as they were nowhere in sight, but he managed to clear the bridge-to-gantry run in 9:55.

Watching him work that underpowered diesel engine like a champ was a thing of beauty. As he stated, the AX’s 1,360 cc diesel engine is a dog once the 720 kg (1,590-pound) car loses its momentum, so he had to push this puny hatchback with what appeared to be nothing more than bicycle tires under it further than some of us may be comfortable in a modern supercar .

Don’t think that he simply hopped in his AX and headed to the `Ring for a quick session when he broke the 10-minute barrier. He did 118 laps around the Nϋrburgring to get to know the course, then it took him 10 full-throttle attempts to get it under 10 minutes. That is some serious perseverance, folks.

Out hats off to you. Regardless of how much you downplayed in on the YouTube post, that was some amazing driving and awesome reflexes.

Thanks to a few new players in the market, the midsized truck battle looks be reviving. News about GM’s new mid-size trucks getting diesels have also stirred up a frenzy, starting with Nissan .

What you see here is the Frontier Diesel Runner, a “concept” truck built to gauge consumer interest in diesel-powered, midsized trucks. The truck itself is barely changed from the production line, but features a 2.8-liter, I-4 turbodiesel built by renowned engine builder Cummins. The Cummins/Nissan partnership isn’t new, however, as the pair have plans to power the next-generation Nissan Titan with a 5.0-liter V-8 turbodiesel in 2015.

The Frontier ’s diesel engine is expected to produce around 200 horsepower and more than 350 pound-feet of torque — all while increasing fuel efficiency by 35 percent over the standard 4.0-liter, gasoline V-6 engine. It’s backed by a ZF-sourced 8HP70 eight-speed automatic transmission. The new engine-transmission combo is expected to tow and haul roughly the same as the conventional gasoline Frontier.

Nissan and Cummins did have to modify the truck slightly to get the powertrain nestled within the engine bay and transmission tunnel. Saving room and further development, this frontier lacks the optional four-wheel-drive and added complexities the system brings to a driveline.

It’s very unlikely the Frontier will be sold with a diesel option in its current generation. Nissan is hard at work developing the second-generation Titan pickup, and will likely turn its attention it the Frontier once development is competed there. We expect a new Frontier won’t be far behind the new 2015 Titan. If Nissan chooses to include a diesel as a powertrain option, it’s likely to happen then.

Diesels seem to be breaking their oil-burning, noisy, smokey stigmas that have haunted them for decades as more and more automakers are now offering clean diesels in their lineups. The latest huge influx of diesel models hails from Audi .

The German automaker, which is owned by Volkswagen Group, has announced a huge diesel push with 11 new TDI “Ultra” models, including the new A6 TDI Ultra detailed here. For starters, the "Ultra" in the TDI Ultra name is Audi’s designation for sustainable mobility that is fully available for everyday use — a long explanation for a TDI A6 that gets darn good fuel mileage while not hindering its common usability.

The heart of the matter is a 2.0-liter, four cylinder diesel that produces 190 horsepower and 295 pound-feet of torque that pushes the A6 from 0 to 60 mph in 8.2 seconds while achieving 53 mpg highway. With stats like that, we don’t mind hugging trees and filing up next to big rigs. Keeping all those trees happy, however, is Audi’s high efficiency SCR system that removes nitrogen oxides from the exhaust. The new system also lets the A6 pass the stringent Euro 6 emission standards with ease.

Backing the 2.0-liter TDI are two optional transmissions: a six-speed manual transmission is standard, followed by the optional seven-speed dual-clutch S tronic automatic. However, opting for the slap-paddle gearbox shoots the A6’s price up €2,250 — roughly $3,000 at the current exchange rates — making rowing your own gears sound evermore attractive.

Furthering the A6 ’s efficiency is the standard start-stop system and driver information center that helps keep track of good driving behavior.

Pricing for the A6 Avant TDI Ultra starts at €42,250 (about$57,000 at today’s exchange rates) and the A6 sedan TDI Ultra starts a little lower at €39,900 (around $54,000). Sales will begin sometime in the first quarter of 2014 and there are no plans yet to release any Ultra models in the U.S.
