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.

Mercedes-Benz SLS AMG GT

Now that we have seen the updated version of the amazing Mercedes SLS AMG , people are switching their focus to new versions of the car. We’ve already heard about the E-Cell version, but the model that is making heads spin is the Diesel SLS AMG.

Wait, what?! A diesel-powered SLS AMG? Well, not really. Polish website, Moto.pl, says Mercedes will be unveiling a diesel powered version of the SLS AMG in the future. This new version will be called the AMG SLS CDI and will be powered by a six-cylinder diesel engine with triple turbochargers. It is said to deliver about 400 HP. Jalopnik, on the other hand, says a diesel-powered SLS AMG will never happen. Both websites neglect to mention any viable sources, so both pieces of information need to be taken with a grain of salt.

Okay, so what’s really going on here? Europe is in high demand for diesel-powered sports car and, back in 2008, it was rumored that AMG was working on a diesel powered high-performance model. That being said, earlier this year, Mercedes AMG announced that a diesel powered vehicle wouldn’t fit in their line-up and they have no intention in following their German automaker rivals. The question is: should we trust them? What do you think? Let us know in the comments section below.

In its standard version the Porsche Panamera Diesel is powered by a 3.0 liter V6 diesel engine that delivers a total of 250 HP. Good, but not very impressive for a luxury sedan like this. So, this is where the German tuner TechArt comes into focus. The tuner has just unveiled a pretty cool tuning package that increases the output from 250 HP to 280 HP (a 30 HP increase). Peak torque goes from 405 lbs-ft to 442 lbs-ft.

For 2,490 euro (or $3,130 at the current exchange rates) clients will get an ECU upgrade and a Techtronic system. As a result the car will sprint from 0 to 60 mph in just 6.6 seconds and up to a top speed of 153 mph.

The tuner is not offering any exterior or interior upgrades for the car, but the Panamera looks pretty cool from factory and it needs no changes to be made.


French automaker Renault has been hard at work redesigning its flagship compact car, the Clio . We actually caught a few pictures of its high-performance variant, the Clio RS, testing with full camo last month . Then, Renault or Ireland mistakenly posted an image of this upcoming vehicle on its website and we were able to get a good look at the future model ahead of schedule.

Renault, of course, did not confirm nor deny that the leaked image was actually of the freshly redesigned Clio, but it is fairly obvious now that they have released official details on this upcoming new hatchback.

Unfortunately, as it has been for the last 23 years, this and all Renault vehicles will not be available in the U.S. The only hope we have of seeing a Renault-built car is the possibility that the upcoming revival of the Alpine brand may make its way to the U.S.

So how does this compact hatchback’s redesign stack up?

TV buffs get the Emmys, movie buffs get the Oscars, and music lovers get the Grammys; so, where does that leave us gearheads? Well, the International Engine of the Year Awards, of course, and the 2012 results are hot off the press!

Ford took home the top prize of International Engine of the Year, with its 999 cc engine found in the European Focus . This engine, despite its petite size, cranks out 125 PS (123 horsepower) and manages to squeeze out 56.5 mpg. The 1.0-liter engine didn’t win a close battle either, it took home top honors by a full 113 points. Points are accumulated based on fuel economy, smoothness, performance, noise and drivability and each engine can only receive 15 of each voter’s total 25 points to give. Needless to say, that was quite a landslide victory.

That’s not the biggest news though, as BMW brought home top honors in four different categories. Bimmer took home the 1.4- to 1.8-liter prize with its 181-horsepower, 1.6-liter engine found in the MINI Cooper S . In the 1.8- to 2.0-liter class, BMW took first prize with its 241-horsepower, 2.0-liter twin-turbocharged four-pot. In the 2.5-liter to 3.0-liter class, BMW wrapped up top honors with its bi-turbo 3.0-liter six-cylinder engine and its 335 horsepower. Last, but certainly not least, BMW took home 1st place in the 3.0- to 4.0-liter class with its 414-horsepower, 4.0-liter V-8 engine.

Despite all of the accolades, the highest mark that BMW achieved in the Engine of the Year award was 5th place, with its 2.0-liter twin-turbo four-banger.

Ram 1500

Anyone that drives a truck in a manner that it is built to be used – you know, actually hauling more than just yourself – will tell you that diesel power is the way to go. Not only are diesel engines far more reliable, but they also boast extraordinary torque for their size and historically get better fuel economy. For some reason unknown to us, the “Big Three” only offer diesel engines in their 3/4-ton and larger trucks, leaving 1/2-ton truck with only gasoline engines to choose from.

With trucks being all about towing these days more than in recent history, a lot of focus has been placed on increasing frame rigidity and driveline quality to bump up towing capacity on the entry-level 1/2-ton pickups, but little has been done to pump up the twisting power needed to get those heavy loads moving (A.K.A. torque).

Well, it looks like Chrysler is getting really serious about the Ram taking over Chevy’s No. 2 slot on the best-selling pickup list. In addition to all of the new enhancements coming in 2013 , reports are pointing toward a diesel variant coming to the 1500 lineup in the near future, as test mule 1500 Rams are being spotted bearing torque-happy diesel power plants.

No, this is not a Cummins diesel engine like most would expect. The engine of choice is the VM 3.0-liter V-6 diesel engine by Fiat . Before you start complaining about Ram straying away from the Cummins engine, understand that this Fiat diesel is no wimp, as it cranks out 241 ponies and 406 pound-feet of torque straight off of the shelf. Add in the fact that it gets up to 28 mpg on the highway and you have a winner.

That would put this diesel at the same torque output as the 5.7-liter HEMI V-8, but allows it to get 10 more MPG on the highway. Given the new frame enhancements in the Ram 1500, we would anticipate a towing rating well over 10,000 lbs from these diesel-power Ram 1500s.

For now, these engines are still in the testing phase, but we will keep you informed if anything changes.

BMW 7-Series

It seems like since the beginning of time, Mercedes has offered a diesel option on its sedans to its U.S. customers, but BMW has always avoided putting these loud and relatively sluggish engines in its U.S.-bound cars. According to various reports, this is all due to come to an end in the near future, as BMW is prepping its 3.0-liter diesel power plant for U.S.-bound 7 Series models.

Nothing is definitive yet and we are still in the early phases of all of the speculation and reports, but we anticipate it to bear a 735d or 740d badge. We also do not know if BMW is planning to further tune the current 3.0-liter diesel engine to exceed its current 265 horsepower and 425 pound-feet of torque, but we certainly anticipate the German auto builder to pump up the horsepower to the 300 horsepower range to attract buyers.

As for fuel economy, we can expect the highway economy to jump from the 17 mpg city and 25 mpg highway to roughly 19 mpg city and 29 mpg highway, given the fact that the much heavier and less aerodynamic X5 gets 26 mpg highway with the same diesel engine. This would make the 7 Series one of the most fuel efficient cars in its class, as the automaker strives to stay ahead of the CAFÉ curve.

Reports are pointing toward this new engine arriving in showrooms sometime in late-2013, but don’t be surprised to see it makes its way over here a little earlier. We will continue to monitor the details of this new engine and keep you updated as more information becomes available.

Maserati Kubang

A few weeks back, we reviewed BMW’s Active Sound system, the system that pipes V-10 engine sounds through the stereo system. We dubbed this system a useless gimmick because a turbo V-8 is a damn fine sounding engine, but owners cannot opt to turn it off without pulling a fuse that also turns off the entire stereo system. Well, it looks like BMW is not alone in this game.

Starting In 2014, Maserati will be selling its first ever diesel-powered vehicle, the Kubang SUV to compete with the Porsche Cayenne diesel in the European market. What Car? asked Maserati’s Vice President of Product Development, Roberto Corradi, about the notoriously beautiful engine sounds that Maserati buyers know and love in their cars and its potential effect on the sales of this diesel SUV.

Corradi responded by stating that engineers are working on using the Kubang’s stereo system to give it a nice engine note. This can only be interpreted as Maserati piping in fake engine sounds through the stereo. Unlike the BMW M5, we see a purpose for this, just like we do in electric cars, as these economic diesel engines just don’t sound cool. This piping in sounds of a high-performance engine can make drivers feel more like they are driving a true Maserati rather than a slower diesel model.

All we ask of Maserati is to install an “On/Off” switch that allows its owner to shut this feature off if he prefers natural engine sounds. As long as that’s taken care of, we have no problem with this feature and actually find it pretty neat.

One Lap America actually has roots dating back to the original Cannonball Sea-to-Shining-Sea Memorial Trophy Dash, known simply as Cannonball. Many of today’s enthusiasts think that Cannonball was simply a movie or plot, but this was actually a real-life cross-country race that included high speeds on U.S. highways.

The original Cannonball only lasted five runs until its organizer, Brock Yates, decided he had better quit this no-holds-barred race before the authorities decide to close it down. In 1984, the Cannonball returned, but was not about making it across the country as fast as possible, but about making it through a course that went throughout the lower 48 states and ended up with the amount of miles closest to Brock’s estimate.

In the modern era of the One Lap America, the race is now about following the rules of the road, as you drive throughout a predetermined course, and between these leisurely drives, you have track events. The scoring of this event is solely based on the track event results, but you and your co-driver(s) must also survive driving 24 hours on end, stopping only to enjoy a “gourmet” gas station hot dog or two along the way.

This 19-event, eight-day racing series just wrapped up on Saturday and we have your full list of winners in each class and we have also broken down a list of all of the oddest and most awesome cars to grace the 2012 running.

German tuner, Hofele Design, has earned a stellar reputation as one of the leading Porsche Cayenne tuners in the world. Their program for the Porsche SUV, called the "Cayster GT 670 ," has been developed for a number of model years for the Cayenne and we’re not the least bit surprised to find out that they’ve released an updated version for the 2012 model.

Made up of a comprehensive aerodynamic body kit to go with a performance program, the 2012 Cayster GT 670 is one Cayenne that has truly been modded to look more aggressive than a standard 2012 Cayenne looks.

The first part of the package is a 14-piece aero kit that includes a number of new "bolt-on" components, including a new front bumper with integrated LED lights, widened wheel arches, a new "PowerDome" hood, new side sills, a rear spoiler and roof wing, and a new rear bumper with its own diffuser. Rounding off the exterior changes are a new set of 20" or 22" alloy wheels that have been finished in either black or silver.

Inside, the German tuner fitted new two-tone "StarLight" leather seats with quilted accents and Hofele Design logos embroidered on the headrests.

As far as performance is concerned, Hofele Design has a number of modifications for both the Cayenne Diesel and Cayenne S Hybrid. For the former, the engine enhancements increased the output of the SUV from the standard 241 horsepower and 405 lb/ft of torque all the way up to 296 horsepower and 479 lb/ft of torque. Meanwhile, the latter gets an increased output of 474 horsepower and 543 lb/ft of torque, a significant improvement from the standard model’s 374 horsepower and 427 lb/ft of torque numbers.

Porsche Boxster

The recent 33rd Vienna Motor Symposium brought out some of the most amazing details about Volkswagen’s future plans, ranging from internal combustion engines to hybrids and electrics. However, one of the most amazing announcements involved a diesel engine for the future Porsche Boxster .

This isn’t the first time Porsche will be offering a diesel engine for their models - they are already doing it with the Cayenne and Panamera - but offering it in two large models and then going to a tiny sports car is quite a jump. It may sound crazy, but Porsche has indicated that it could happen in the future.

Porsche R&D Chief and VW Group’s engine guru Wolfgang Hatz said at the conference that he is "firmly convinced the internal combustion engine will remain dominant in the foreseeable future. The diesel has arrived and is a firm part of our strategy. There will be more powerful variations with Porsche-like performance. It would be wrong to say no to a Boxster diesel for all times."

This news follows the announcement of the Porsche Boxster E, which has been in the prototype stage for a couple of years ans should be debuting for the 2013 MY. The Boxster E is powered by two independent electric motors - one on the front axle and one on the rear - that develop a total power output of 241 HP and a maximum total torque of 398 lbs-ft at a maximum engine speed of approximately 12,000 rpm. With this amount of power, the car will sprint from 0 to 60 mph in 5.5 seconds and can hit a top speed of 124 mph, all while producing zero tailpipe emissions.

The question is which type of engine would you prefer for the Boxster : a diesel or a full electric? Let us know in the comments section below!
