If you want a powerful, fast Porsche Cayenne, Stuttgart has no shortage of choices on offer, topping out with the mental 550 horsepower Turbo S. Of course, there are plenty of aftermarket tuners willing to take the unreasonable up to downright silly proportions, but if you were looking for power and speed without sacrificing too much fuel, for the most part you were advised to look elsewhere. After all, a big SUV isn't exactly the ideal platform for either. But then along comes Porsche tuner extraordinaire Techart to show you the way with its own custom Porsche Cayenne Diesel.

Boosting output from 240 hp and 406 lb-ft of torque to a hefty 290 hp and 465 lb-ft, the Techart Cayenne Diesel drops the stock 0-60 time of 8.3 seconds down to a handy 7.7 seconds, all without harming the vehicle's fuel economy or emissions numbers. Nice work, but the most impressive part is the modified torque curve that gives the big oil-burner accessible grunt from as low as 1,000 rpm.

Techart has also crafted a unique Aerokit 1 for the diesel sport-ute, giving it a more aggressive stance while improving airflow, capped with giant 21-inch alloys or optional 22s. The British tuning house offers a turnkey model at £55,500 (around $89k USD) with the body kit and engine mods, or can fit an existing diesel Cayenne with the Aerokit for £15,000 ($24k) and the engine kit for £2,500 ($4k). Details in the press release after the jump and high-res images are on offer in the gallery below.

Porsche plans to expand its Panamera line-up to include three new powerplants – a Volkswagen-sourced V6, a diesel and some manner of hybrid – but in addition to offering new engines, the automaker may offer a harder, more performance-oriented model to slot in above the Turbo.

Similar to the strategy Porsche employed with the Cayenne, this new model – which could be dubbed the Turbo S or GTS – would nix the Turbo model's standard air suspension and instead fit a set of performance-tuned springs and shocks to maximize grip and on-track prowess.

As for future powertrains, a senior Porsche executive told Autocar that VAG's V6 and V8 diesels could be fitted to future Panameras, and we wouldn't be surprised to find the new Audi S4's supercharged, petrol-powered 3.0-liter V6 in Porsche's first production sedan in the coming years.

General Motors, Ford, Chrysler, Honda and everyone else may not think there is much of a market for mainstream diesel vehicles in the United States, but Volkswagen would beg to differ. Since it launched its new generation diesels last fall in the Jetta and earlier this year in the Touareg, they have been selling like hotcakes with June being its best month yet. Last month was the best sales month to date for the Sportwagen with 1,982 sales and a whopping 81% of those were equipped with the 2.0-liter TDI four-cylinder.

Among the 8,431 Jetta sedans sold in June, 40% were diesel powered. And while the Touareg followed most other SUVs with a 41% overall decline to only 330 units in June, 29% of those had the 3.0-liter V6 TDI engine. Rabbit sales were down 69% in June, but a redesigned Golf is arriving in September, including a TDI – and if fuel prices keep climbing through the summer, it could see a huge sales spike as well.

Diesel's near-term prospects in America took a huge hit with the revelation that nine diesel-powered 2010 models are on hold. Ford, General Motors, Chrysler, Toyota, Honda, and Nissan have put the kibosh on rolling out more oil burners due to cost and perception issues.

Toyota's obviously on a hybrid run and doesn't want to expel the effort or expense of investing in diesel for the American market -- and having to overcome America's dirty diesel perceptions. The others, as mass market manufacturers, simply need more justification for the cost and complexity of oilburners in order to make the case for consumers to spend more.

Additionally, diesel's benefits are weighted differently according to EPA or CAFE standards. The EPA mileage numbers present diesels well, but CAFE's differing fuel mileage equation makes gas-hybrids look better than diesels, and CAFE is something all automakers are looking at. However, you'll notice that German brands aren't mentioned -- their price premium and European diesel volumes make a worthwhile case for diesels, so those diesel Jetta Sportwagons won't be going away any time soon.

The BMW 1-Series is a much bigger deal in Europe than it is here in the States. In the US, we can choose among the 128 and 135, and both options come standard with a six-cylinder engine. Overseas, you can pick up the 1 with two, three, four or five doors, and with a wide variety of four cylinder gasoline and diesel powertrains.

To keep the good times rolling, team Bimmer is again expanding the 1-Series lineup for 2010. Two new models, the Lifestyle and Sport models, will offer RWD performance in a three- or five-door package beginning this September. The Lifestyle model offers special edition Marrakesh Brown Metallic paint, unique brown body color interior components, chrome-tipped exhaust and 17-inch light aluminum rims. The Sport model includes the M Sports Package, with a sports tuned suspension, unique dual spoke aluminum rims, stainless steel pedals, and an M steering wheel and gearshift lever.

On the engine front, a pair of 2.0-liter engines find their way under the bonnet of a 1-Series. The petrol engine utilizes direct injection tech and packs 170 ponies to go along with 155 lb-ft. With the gas-powered 2.0-liter engine, the 1-Series can hit 60 in 7.8 seconds, and it carries a top speed of 149 mph.

The diesel variant packs 143 hp and 221 lb-ft, helping to propel the 118d to 60 in nine seconds. The story of merit is fuel economy and CO2 emissions, where where it achieves 4.5 liters/100 kilometers (about 52 mpg US) and a CO2 emission rating of 119 grams per kilometer. Hit the jump for more info from BMW's painfully detailed press release.

BMW has just announced an upgraded version of its 3.0-liter inline six-cylinder diesel engine. The new version retains the same displacement, yet output for the European spec version is increased from 286 horsepower and 428 lb-ft of torque to 306 hp and 442 lb-ft. At the same time, fuel consumption and CO2 emissions are reduced by four percent compared to the previous version.

BMW has updated the fuel injection system to its latest generation common rail system. That means the injector pressure has been bumped from 1,600 BAR (23,000 psi) to 2,000 BAR (29,000 psi), allowing for even more precise metering of the fuel flow. The dual stage turbocharger system is now also more efficient. Since BMW only just introduced a version of the previous engine with U.S. legal after-treatment systems in late 2008, it seems unlikely that the U.S. will receive the upgrades in the near future.

Many communities have felt the sting of closing dealerships, but it appears for some that capitalism Mahindra is coming to the rescue. The Indian truck manufacturer is sweeping in to sign up recently booted Chrysler dealers to sell their fuel efficient diesel pickups. Mahindra is hoping to soon have 300 dealers online and ready to sell the inexpensive trucks. Mahindra had earlier announced that it had over 300 dealers signed up to sell the truck, but the difficult economy and a lack of available credit likely prevented many from having a dealership online in time for the truck's fall introduction. The experienced, ready-for-business Chrysler dealerships are like a gift placed in the lap of the Indian truck maker.

In the Detroit area, the Detroit Free Press is reporting that two former Chrysler dealers will begin selling the truck this fall. The Mahindra truck will exclusively contain 2.2-liter diesel powertrains mated to six speed transmissions. The trucks should easily be able to hit 30 mpg on the highway, while also giving owners the ability to carry a 1.3-ton payload. The Mahindra truck will also cost 10-15% less than comparable Japanese offerings.

The Free Press also reported that Mahindra is planning a diesel-powered SUV for mid-2010. The SUV will reportedly have a price tag in the $13-15k range.

A facelifted version of Hyundai's popular Santa Fe crossover has just been unwrapped in its home market, along with a pair of new diesel engines.

As this first image shows, the model's exterior update is a mild one, with a modestly tweaked grille, lower fascia, new fog lamps and side mirrors being the most noticeable changes. While there are likely a few tweaks around back and inside, we won't know for sure until we can source additional images and information.

Regardless, as we hear it, the Korean Domestic Market cute-ute will offer a choice of four-cylinder diesel powerplants - a 2.0-liter mill giving 137 kW and 392 Nm of torque (184 hp and 289 lb-ft), while a bigger 2.2-liter powerplant is said to provide 149 kW and 436 Nm of twist (200 hp and 322 lb-ft).

We asked our sources at Hyundai if we could expect to see these changes, and while they stopped short of confirming this exact facelift, AB's mole did allow that a "freshened" model is indeed expected in dealers early next year. Better yet, that model will include new powertrain options – but sadly, no diesel.

British police have an expensive problem. It's not crime and it isn't corruption, it's much worse. The £1 million problem is stupidity. Over the course of three years, UK cops have on 4,709 occasions put the wrong fuel in their police cruisers. That's an average of four cars damaged per day, with damages of £6,500 a week. That's more than $1.6 million USD. Blimey.

Each time the wrong fuel is added, the very expensive fuel has to be drained, and in many cases engines have to be repaired. According to the Mirror, one force, The Met, had four times as expensive a problem as any other group, with £194,212 in damage ($316k USD) over three years. In one year alone, the pump-challenged bunch had 287 erroneous re-fuels from its 6,500 unit fleet at a taxpayer cost of £84,992 ($138k USD). That's a mis-fuel rate of .09%.

A group called TaxPayers' Alliance demanded fueling info under the Freedom of Information act from 52 forces in the UK. Eight forces rejected the request, and four more didn't respond. The public action group poured over data over a four month period to come up with the staggering sum of bungled fill-ups.

TaxPayers' Alliance chief Matthew Elliott doesn't mince words when talking about the size and scope of the fuel problem. "Every car damaged is thousands of pounds diverted away from the fight against crime. One would hope our police were more on the ball." One would hope.

To combat the expensive fuel mix-up issue, North Wales placed yellow stickers labeled 'DIESEL' back in 2006, but that didn't stop officers from pumping petrol on 39 different occasions. Many forces have stated that they've tried many things to combat the problem, but apparently only one solution has worked. Humberside has had only one mis-fuel, at a cost of £51. They have an all-gas fleet, which they say saves £250,000 a year. Hmmm....

Over the last several years, we've heard a lot of excuses from many auto executives as to why their companies aren't offering diesel engines in their American market cars. Yesterday, General Motors' Mark LaNeve, the company's vice president of sales and marketing, made an appearance on C-SPAN's Washington Journal. The final question of the segment came from a viewer wondering why GM has failed to offer U.S. consumers the chance to buy some of the high-mileage diesel cars it offers in Europe.

It would appear that LaNeve might have done better to take a pass on the question. Instead of talking about the cost of making those diesels meet U.S. emissions regulations or the difficulty in helping Americans overcome the misconceptions about the fuel, he claimed that no one has successfully cracked the diesel passenger nut in the U.S. (which based on VW's May sales appears to be wrong). More startlingly, LaNeve went on to claim that diesel is $1.25 a gallon more expensive than gasoline. According to the Energy Information Agency, the national average for diesel this week is $2.35 / gallon while regular gas is $2.52 or $0.17 more than diesel. Admittedly, the fact that diesel is now cheaper than 87 octane gas is a recent development (a trend that nobody is sure how long it will last), but – going on national television and quoting outdated fuel prices as a reason for your bankrupt company's business decisions... well, that doesn't strike us as a terribly hot idea.

You can hear the question and response at 20:30 into the video replay over at C-SPAN.
