Ford rolls out diesel Focus ST at Goodwood [w/poll]

If you're in the market for a hot hatch, there are some excellent choices at your disposal - especially if you live in Europe. But if you want a diesel, well, your choices become rather more limited. Volkswagen tends to that niche market with the Golf GTD (essentially an oil-burning version of the GTI available Stateside), but that's about the extent of it. The pleas of those looking for more diesel-burning hot hatch choices haven't fallen on deaf ears at Ford, with the Blue Oval not only rolling out a facelifted gas-powered Focus ST at the Goodwood Festival of Speed this weekend, but also a new diesel version as well.
The diesel Focus ST (which we hope and pray isn't marketed as the STD) packs a 2.0-liter turbodiesel four producing 182 horsepower and 295 pound-feet of torque to propel the oil-burning hot hatch to 62 in 8.1 seconds en route to a top speed of 135 miles per hour. With less power and only slightly more torque, that makes the diesel Focus ST considerably slower than the gasoline one, which packs 252 hp and 270 lb-ft, runs to 62 in 6.5 seconds and tops out at 154 mph, but (in a testament to how far particulate filters have come) the diesel model cuts carbon emissions by nearly a third compared to the petrol version and returns about 50-percent better fuel economy, which makes that much more of a difference in markets where diesel is already priced better than gasoline at the pump.
For buyers who wouldn't consider anything other than a diesel, it also represents 23-percent more power than the previous top-level diesel Focus. The VW Golf GTD, for reference, offers up 181 hp (just 1 horse less), 280 lb-ft (15 fewer torques) but is somehow estimated to reach 60 in a considerably fleeter 7.4 seconds.

A cool boost to turbocharger performance

Since the advent of the forced-induction engine, we have been looking for ways to get every drop of performance we can. There are many approaches to getting additional power using better intercooling, water injection, or even adding nitrous oxide. One take on a short instant burst of power is being researched by Mahle and involves providing supercooled air to an engine, which allows it to burn a leaner fuel mixture and produce more power. The supercooling idea is not new and was examined by Ford in 1993 on the Mustang Mach III concept car, then brought up again in 2003 with the SVT F-150 Lightning concept. Ford called its system the SuperCooler; it was designed to work with any turbocharged or supercharged engine equipped with a water-to-air intercooler. The system on the Lightning concept used a small tank of antifreeze that was hooked up to the truck air conditioning compressor. The air conditioning compressor cooled the antifreeze down to about 30 degrees. The other side of the tank was hooked up to the air-to-water intercooler, which usually had a temperature over 100 degrees. Once the antifreeze was circulated from the tank into the intercooler, it would lower the intercooler temperature and provide for a cooler, denser air charge into the engine; the result was around 50 extra horsepower for a burst of about 30 seconds to a minute, depending on the size of the tank. The system for the Lightning was to be offered as a $750 option and would have been targeted towards drag racers and the like, as it could be used for a run down the drag strip and then re-cooled by the time the truck was back in line. The system was fairly non-intrusive – it only weighed about 25 pounds and did not require a new compressor or intercooler. But as with many concepts, it was ultimately scrapped. The technology was always stuck in the back of my mind, but with larger and more powerful engines being produced it could not find its place. With the advent of new fuel economy standards, we have seen small-displacement turbocharged engines pop up and they seem like the perfect candidate for this type of technology. Ford's EcoBoost 1.0-liter three-cylinder turbocharged engine, as used in the Fiesta and Focus, is one such candidate for this technology. It would add a negligent amount of weight but could provide a boost of 10 to 20 horsepower when needed, like merging onto the highway or catching up to traffic.

2016 Ford Focus RS leaked ahead of official debut

We won't officially see the new Ford Focus RS until the Blue Oval shows it to the world at an event on Tuesday, but here it is ahead of time, courtesy of the folks at Evo. As you can see, this is one hot little hatch, and if Evo's story is to be believed, those aggressive looks will be backed up with some pretty serious performance. Power is said to come from Ford's 2.3-liter EcoBoost inline four-cylinder engine, though the magazine's estimate of 250 horsepower seems awfully conservative to us (considering that's less than the current Focus ST). If earlier reports are to be believed, we think the RS will come packing more like 300 hp, if not more. For the first time, the Focus RS will use all-wheel drive with brake-operated torque-vectoring, and Evo says that up to 70 percent of the engine's power can be sent to the rear wheels. Hitting 60 miles per hour will reportedly take less than five seconds. Otherwise, it's business as usual, with a mean-looking exterior complete with the necessary aero bits (notice that wing!), and inside, we can see a beefy set of Recaro chairs. That's really all we know for now, but stay tuned for more when the Focus RS makes its official debut in the not-too-distant future. Related Video:
