  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.

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?

It looks like the Sport Quattro won’t be the only concept Audi will display at the 2013 Frankfurt Motor Show . Don’t be shocked at how familiar this concept looks, as Audi teamed up with Italdesign Giugiaro — the same folks that brought you the wildly styled 2014 Parcour — to develop this model.

The new nanuk concept is a two-door crossover powered by a V-10 TDI engine, and If you remember, this is not the first concept offered by Audi to feature a TDI engine. We saw a TDI-powered concept at the 2008 Detroit Auto Show where Audi unveiled the R8 V12 TDI concept . This makes us hope that the previously rumored R8 TDI supercar could become a reality after all, especially if you take a closer look at the output delivered by the nanuk.

As "Nanuk" is no ordinary name, and Audi didn’t bother to offer us any explanation on choosing it, we did a little research and found out that in Inuit mythology Nanuk ("Nanook") was the master of bears, who decided if the hunters deserved success in finding and hunting bears. Trying to figure out what this has to do with cars is enough to make your head spin, but car naming has become a rather odd thing in recent years.

After the new generation Porsche Panamera made its world debut at the 2013 Auto China in Shanghai, the new diesel version of the luxury sedan will be unveiled next week at the 2013 Frankfurt Motor Show . When compared to the previous generation, the new Panamera Diesel delivers an extra 50 horsepower and is both faster and more fuel efficient.

Next to the more powerful engine, the revised Panamera Diesel will adopt the same design language we have seen in the gasoline version. It will get a revised front fascia with redesigned headlights and larger air intakes and for the rear, a wider spoiler and redesigned taillights. As usual, no changes were made on the interior.

The new generation Panamera Diesel will be put on sale in January 2014 at a starting price of €85,300 - about $113,000 at the current exchange rates.

Back when we first received details on the new X5 M50d, they were all still in their preliminary phase, and now BMW has finally unveiled all of the official information on its resident diesel crossover .

As no surprise, this diesel X5 will be offered with the same upgrades as the standard X5, including a new front and rear fascia, a new set of headlights and an updated interior.

The new X5 M50d will also carry a three-stage turbocharged 3.0-liter powerplant that is set to send plenty of horsepower and amazing torque through an eight-speed automatic box and out to all four wheels. This accounts for a 0-to-100 km/h (62 mph) time of under 6 seconds and fuel economy that will blow the doors off of many gasoline-powered economy cars.

The bad news is that to date, there is no mention of the new BMW X5 M50d coming to the U.S. market, hence it being a 2013 model year instead of a 2014.

Update 8/30/2013: BMW has revealed all of the specifics on the new X5 M50d. You can read all of the details after the jump.

Land Rover is taking fuel economy concerns with a stiff upper lip and a cup of tea, relaxed as it starts taking UK orders for its 45 mpg 2015 Range Rover SDV6 Hybrid flagship starting in September 2013. The first customer deliveries are expected in early 2014, wearing far fewer off-road accessories and prepared for a life of luxury.

This pair of test prototypes is enduring the opposite of luxury: a 10,000-mile durability journey from Land Rover headquarters in England to Tata Group ’s home base in Mumbai. Called the Silk Trail 2013 experience, the plucky Brits seem to have forgotten their own maritime excellence, and the blue part of the map that has long been the best passage to India.

Calling it the Silk Trail is more accurate than its other description, the Silk Road. Mud up to the door mirrors cannot stop the Range Rover Hybrid’s mission.

Going over land is a bold undertaking, and also highlights the production 2015 Range Rover Hybrid’s fuel economy and off-road credentials along the way. Arriving in Mumbai around 55 days later, taking a brand new Range Rover into dozens of foreign countries along the way is certainly a vote of confidence in its reliability - long a sore spot for this advanced machine.

A 3.0-liter diesel engine is paired with a jumbo 35kWh Li-ion battery pack, which is fully production-ready and will also be rolled out on the seven-seat 2015 Range Rover Sport SDV6 Hybrid as well.

The diesel-electric power is not exactly peachy news for U.S. Range Rover devotees, but the technology package should work well with Land Rover ’s new 3.0-liter supercharged V-6 as well.

Updated 09/13/2013: When Land Rover launched the first details on the Range Rover Hybrid everyone believed it will be an European-only model. However, in a recent interview Andy Goss, the current CEO of Jaguar Land Rover USA confirmed that a North American version of the Range Rover hybrid "It’s not a matter of ‘if,’ but ‘when.’" (LeftLaneNews)

A dyno, a laptop and a dream: the BBM Motorsport upgrade for the E91 generation of BMW 3 Series brings an extra 251 pound-feet of torque with a simple induction, exhaust and ECU re-flash. Yep, this 330d has 635 pound-feet of torque to go with its appealing red foil wrap and 19-inch BBS alloys.

BBM Motorsport’s impressive project really shows the scope of tasteful performance modifications to this generation of BMW 3 Series wagons. From looking like it probably has melted candy in the leather seats, to now looking at home making sparks on the Nordschleife and racing RS6 Avants on the autobahn until the tires or nerves call it quits.

This revamp is pretty cost effective as well, with BBM offering component sales for guys who might only be able to afford one upgrade at a time. The LED lights and matte wrap might be eye-catching, but the real gold comes from 30 minutes of ‘hotsynching’ to the BMW ’s OBDII port.

A more effective ECU re-flash is hard to recall, but as we all know, tuners are not quite OEM in their durability and long-term reliability testing. Does the BBM kit push the limits of this excellent BMW turbo-diesel engine too high?

Despite sounding like a tractor or school bus to American ears, there is actually much more soulful inline-six bellow from the BBM upgrades. Bellows are the last thing you hear before your head meets the seat when the torque comes in a knockout punch.

Kahn Design has revealed the styling of their latest Land Rover Defender 90 up-fit, which includes a comprehensive exterior and interior makeover and the Chelsea Wide Track name. The Kahn personalization options list is immense, with near limitless combinations of paints, tweeds and leathers to camouflage this classic off-road machine in urban war paint.

Ever the victim of aggressive personalization, the Defender is still trendy because of how impractical and hilariously uncomfortable it is to drive. The mechanicals for Kahn ’s extreme makeover stay the same as the stock model, aside from some light engine enhancements to the 2.2-liter turbo diesel and of course the giant wheel/tire/spring package.

These vehicles are part of a new co-branding effort between Kahn Design and the Chelsea Truck Company. Forming what must be the most absurdly wordy name in history, the truck is best referred to as the Chelsea Defender. Offered in the 90 or 110-inch body styles, the Chelsea Defender offers some tasteful and some not-so-tasteful ways for customers to part with their cash.

Cynicism about modified Defenders is possible only from afar. Driving a Defender is still a strange treat off road, but its rude manners on pavement mean that owners have little choice: they must try to engineer improvements themselves via the aftermarket.

Kahn’s custom Land Rover will not be joining the official U.S. price lists any time soon. A fun competitor might be the Nissan Murano CrossCarbiolet ] - but sadly, the convertible Defender is not one of the five body styles offered for this legendary truck’s designer up-fit.
