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.

The words ’diesel’ and ’convertible’ aren’t uttered in the same sentence in the States. The original diesel engines were loud, stinky, and more often than not, resembled a smoke-billowing cigarette. Automakers would have had to be crazy to turn out a diesel convertible during that time. Nowadays, however, clean diesel engines are getting churned out like anti-smoking commercials and a source close to Volkswagen has confirmed that the company is bringing the first diesel convertible to the US in the form of the new Beetle Cabrio TDI.

The 2.0 TDI engine delivers a total of 138 HP and has a fuel economy of 40 mpg fuel economy in the Highway cycle, 29 mpg in City driving, and 33 mpg combined. It will be offered with either a standard 6-speed manual gearbox or an optional 6-speed dual clutch transmission.

The 2013 Volkswagen Beetle Cabrio will feature the same new design line as found in the coupe model . That new design can be seen from the front bumper and front air inlet, the straight lines of the bonnet edges, the precisely drawn line between the A-pillar and C-pillar, and the styling of the rear lights. The car also gets a lower profile, is substantially wider, the front bonnet is longer, and the front windscreen is shifted further back and has a much steeper incline.

Porsche is offering up proof that even the most luxurious cars can be fuel efficient with the debut of a V6 diesel engine on the Porsche Panamera .

The new Panamera Diesel is now equipped with a 3.0 liter V6 diesel engine that delivers a total of 250 HP and will sprint from 0 to 60 mph in 6.8 seconds, while top speed is limited to 150 mph. What’s even more impressive is that the sports sedan was tested and received an impressive 745 miles on an 80 liter tank with an average fuel consumption of only 6.3 liters per 100 kilometers, or about 37 mpg.

In Germany, the new Panamera Diesel will be priced at about 80,183 euro, or about $119,500 at the current exchange rates, and will go on sale in August 2011. There hasn’t been any mention as to if the Panamera Diesel will be available on the US market.

Shortly after its official launch, the Alfa Romeo Giulietta has become quite a successful model. And as customers always ask for more the company is offering a new engine in the line-up: a new 2.0 JTDM-2 equipped with the latest generation JTDM-2 MultiJet Common Rail system.

This technology, combined with an electronically controlled variable geometry turbocharger delivers a total of 140 HP and a peak torque of 350 NM at just 1750 rpm (with the D.N.A. selector in Dynamic position) and 320 NM at 1500 rpm (in Normal) - giving it the highest torque in its class compared to similarly efficient and powerful engines.

Equipped with this engine, the new Giulietta will sprint from 0 to 60 mph in 9 seconds and will be capable of a top speed of 127 mph. The model comes equipped with DPF (Diesel Particulate Filter) and Start&Stop as standard, a close coupled diesel particulate filter and a built-in EGR (Exhaust Gas Recirculation) system that improves control of temperature and gas flow.

There are so many different variations and tuning packages for the Mini Cooper , sometimes it’s difficult to keep track of which Cooper is which. It has a style and shape that plays well with new additions, updates, trim levels, and packages so the most obvious thing to do is add another for greedy consumption. Mini ’s latest toy is a new SD version which just so happens to be their most powerful diesel Cooper ever, and yet another reason the Mini Cooper is so darn popular.

The Mini Cooper SD is powered by a 2.0-liter four-cylinder turbodiesel engine that delivers an impressive 143 hp at 4,000 rpm and a peak torque of 225 lb-ft available between 1,750 and 2,700 rpm. This leaves the other diesel variants in the Cooper line in the dust since the Cooper D only produces 112hp and the Cooper One D only delivers 114hp. U.S. customers need not start jumping for joy just yet; Mini has yet to decide whether the diesel SD will be taking a trip across the ocean to see us.

Whether we get a piece of this action or not, Mini will be bringing the SD trim level to different Mini models, including the Cooper, Cooper Convertible, Clubman , and Countryman versions. The Mini Cooper SD will be making its world debut at the 2011 Geneva Motor Show with sales beginning shortly thereafter.

Generally, the focus of diesel cars is on fuel economy and not so much on performance, but with a little help from the capable hands of tuners, a diesel car can become what it should have been from the start: a powerful and environmentally friendly machine. Superchips, for instance, has prepared an ECU remap for the 2010 Porsche Cayenne Diesel 3.0 TDI. With their help, the output for the Cayenne has been boosted by up to 47 bhp at 4044 rpm, while the peak torque has been increased by an impressive 82 Nm. The best part about this kit is that, even with increased power, the fuel economy stays exactly the same at just 8.2 liters/100 kilometers (equal to 34.4 mpg imp). In fact, sometimes the fuel economy even improved due to the extra low rev torque available.

The result is quite impressive for a 4,630-pound SUV. The standard Cayenne Diesel 3.0 TDI develops 240 HP, but the Cayenne by Superchips now goes up to 287 HP, which is a little bit closer to the SUV’s gas-powered brother that develops 300 HP.

The Porsche Cayenne Diesel by Superchips is available now for £445 and comes with a 12 month/30,000 supplementary warranty.

While most of the manufacturers are considering hybrid and electric vehicles, Mercedes is considering a diesel version of the GLK crossover for the US market.

During an interview at the Los Angeles Auto Show, Mercedes-Benz USA President Ernst Lieb said: "We’ve got the GLK coming. And the next-generation C-Class sedan will share the 2.2L 4-cylinder clean-diesel engine that bears the brand’s Bluetec trademark. The C-Class will feature diesel availability right from the start when it arrives in 2013." The E-Class will also get a new diesel engine starting 2011. All of these new engines will include Mercedes new BlueTec technology.

You can see that Mercedes has big plans for diesel engines in the US market: "Overall, our goal is to be somewhere in the range of 15% to 20%,” he says. “And we’re slowly growing this."

This is quite an impressive move considering Mercedes recently had to recall about 2,300 2011 diesel models, including the M-Class, GL-Class , E-Class, and R-Class, due to leaky fuel filters.

The journey towards developing alternative fuel sources took another step after two Audi A3 s successful traveled 1,000 miles by using a new synthetic diesel fuel. Pretty impressive, if we do say so ourselves.

The two 2011 A3 TDI models were using RenDiesel, a synthetic fuel that’s made from organic compounds and green waste that are most commonly found in landfills. The fuel, which supposedly produces less volatile organic compound (VOC) emissions than regular diesel fuel or ethanol, is being produced by RenTech in Rialto, California. RenTech, together with Audi of America and Green Car Journal, managed to successfully fuel the two A3 TDI models from Eureka, California all the way to San Diego, California – a distance of somewhere around 1,000 miles.

This project not only proved that the new type of synthetic diesel fuel is capable of fueling a car at great distances, but it also was able to boost up the A3 TDI’s mileage rating at 42 miles per gallon – one car was able to average 43 mpg while the other A3 TDI scored 39.7 mpg.

This latest development may not hit home to a lot of people, but the development of a clean-burning synthetic diesel fuel like RenDiesel is one way to make the purchasing of diesel vehicles more worth it. After all, in a world where fuel-efficiency is of paramount importance to a lot of people, the development of a synthetic diesel like RenDiesel could pave the way for more diesel cars to be enjoyed out on the road.

Don’t you wish you were a cop in Britain? While our American police officers have to drive around in Chevrolet Impalas and Ford Crown Victorias, the UK is getting some Beamers.

BMW is giving all 52 of the country’s police forces these new products, including the new 5-Series , X1 , X3, xDrive20d, and the X5 xDrive30d and xDrive40d SUVs. Every one of these vehicles will be powered by diesel fuel because the environment is just as important as catching crooks.

The United Kingdom will also get a 330d sedan High Performance Pursuit Vehicle. This will be the machine you will see running down the baddies at high speeds on the motorways. Despite having these amazing cars, the UK will still rely on cameras to catch speeders on the motorway.

The German automaker will also include the R1200 RF-P Police bike, which should be used on Britain’s crowded roads and in cities.

Audi has added a new version to its 2011 Q7 line-up. The new Q7 3.0 TDI Quattro delivers a total of 204 HP and has a fuel consumption of 32.67 mpg. In Germany the new model is priced at 51,800 euros (around $72,000 at the current exchange rates).

The new 3.0 liter V6 engine weighs far less than 440.92 lb and extensive measures minimize internal friction. Innovative thermal management – a new feature of many Audi engines – is particularly complex in the 3.0 TDI. The crankcase and the cylinder heads have separate cooling water circuits; coolant is not circulated within the block while the engine is warming up. This engine comes equipped with a eight-speed tiptronic transmission.

Equipped with the new engine, the Q7 will sprint from 0 to 60 mph in 9.1 seconds and will hit a top speed of 127 mph (with an optional air suspension).

Mercedes has unveiled at the Paris Auto Show the S 250 CDI BlueEFFICIENCY, the world’s most fuel-efficient luxury sedan. It is powered by four-cylinder turbo engine that delivers 204 HP and 500 NM of torque and delivers a total of 5,7 liters engine per 100 kilometers. The car sprints from 0 to 60 mph in just 8,2 seconds and can hit a top speed of 150 mph.

The engine is mated to ECO start/stop system. This system shuts down the engine as soon as the vehicle comes to a stop – e.g. at traffic lights – and the driver continues to press the brake pedal while it is stationary. The engine starts again immediately as soon as the driver releases the brake pedal or presses the accelerator pedal.

The ECO start/stop function will not switch the engine off for example if the desired interior temperature has yet to be reached, if the driver has switched off the system or if drive programmes "S" or "M" are active. An intelligent control system ensures that all functions and comfort systems otherwise remain in operation during the stop phase.
