Mark Higgins sets new Isle of Man record in Subaru STI

Subaru has done it again, setting a new four-wheel lap record around the 37.75-mile TT Mountain Course at the Isle of Man. Mark Higgins in a 2015 WRX STI rocketed through the country roads at an average speed of 116.40 miles per hour to circle the track in 19 minutes, 26 seconds, thereby beating his previous record of 19 minutes 56.7 seconds from 2011 in an STI.
According to Subaru, speeds during the lap ranged from as little as 30 mph to over 160 mph. The STI was mostly stock with the only major mechanical change being different springs and dampers to handle the course's famous bumps at such sustained high speeds. For safety, it also had a rollcage, racing harness, and fire suppression system.
"It was quite a lap we did today and I am really happy to have another record in the bank. The chassis of the new car is so much better it really allowed me to pick up time in each sector in the more technical parts of the course," said Higgins about the run in the Subaru.

The 2019 Subaru STI S209 has an intercooler sprayer, here's what it looks like when you activate it

The 2019 Subaru STI S209 gets a lot of features that distinguish it from your average WRX STI including wide body work, a giant wing, additional chassis braces and an extra 31 horsepower. It also brings back a performance gizmo that hasn't been featured in a U.S. market Subaru since 2007: the intercooler sprayer. As the name implies, it sprays cool water onto the air-to-air intercooler when pressing a button. In the case of the S209, that button is one of the paddles on the back of the steering wheel. That triggers the water nozzles hidden in the hood scoop to spray water. You can see what happens in the video below. Note that when the car is in motion, air would carry the spray farther back covering more of the intercooler. Now why would you want an intercooler sprayer? Well, the S209, like all WRX and STI models, uses an air-to-air intercooler to cool off hot air coming from the turbocharger on its way to the intake manifold. The cooler your air, the denser it is, meaning more oxygen to combine with fuel to turn into more power. The effectiveness of the intercooler depends partly on the temperature of the outside air flowing over the intercooler. If it's really hot out, it's not as effective. So spraying water onto the intercooler can counter this to ensure that the car is making maximum horsepower even in toasty conditions. This also means that although this may feel like some special secret performance-boosting weapon, it's really only effective in specific circumstances, and will just get you back to normal power, rather than make the car noticeably faster on the street. Long track days in the summer and after waiting in line at the drag strip or autocross are the kinds of situations where you could see power diminish due to hot air and a lack of moving air. Normal driving won't necessitate its use nor will driving in cool temperatures. In fact, the S209's owner's manual specifically says not to use the sprayer in temperatures below 41 degrees Fahrenheit because of the risk of frozen water in the tank. That brings us to another aspect of the intercooler sprayer: maintenance. In fairness, there isn't much to maintain, but if you want to use the system, you do need to keep the tank filled. It's located in the trunk where the spare tire would normally be. Inside of course is a water pump that connects to hoses that run water to the front. There is a warning light that will illuminate on the instrument panel if it runs low.

Prototype Subaru Impreza 22B emerges from obscurity

Ask a gearhead what they think is the greatest Subaru built and the answer is probably something related to rally Imprezas – unless you're talking to a more quirky sort who'd throw out the SVX, XT or the bed-mounted jump seats of a Brat. But in any case, the 1990s rally Subarus are great, their road-going versions are brilliant and the rarest of all is the bulging 22B, which commands strong money due to its very limited availability. The Impreza 22B, reportedly named so for its 2.2-liter turbo boxer, but which also refers to the hexadecimal value of 555, Subaru's rally sponsor, was a widebody special with a bigger engine and more STI magic than other WRX variants. Officially it had 280 horsepower, but almost every Japanese performance car was advertised with that amount at the time – true figures take a dyno run or a dedicated mind to uncover. In addition to the modified body, the suspension was 22B-specific, as was the aero. The 2,800-pound 22B took just 5 seconds to hit 60 mph, a strong feat for 1998, and on the right road with the right kind of driver it is likely to be unparalleled for its era. As rare as any 22B is, there are also Subaru-built prototype cars that weren't part of the initial 400-car Japanese production run or the official 16-unit UK-bound batch, or the five Australian market cars. Some sources say there were 424 22Bs made, some mention a different number, and the prototypes are understandably the most coveted, least obtainable ones. Which brings us to this car currently for sale, which just so happens to be one of three known "000/400" series prototypes with just 55 kilometers (34 miles) on the digital odometer. Is this an actual wheeled unicorn? Contempo Concept, the Hong Kong-based dealer that also stocked the Miata Roadster Coupe we featured, has provided precious little information about this particular car, other than some very good sales photos that show the 22B in mint condition, complete with the 000/400 prototype plaque. There's no mention of the price – this Subaru is likely to have entered the "If you must ask, you cannot afford it" class of cars. It's not immediately obvious whether its prototype status would make it difficult, if impossible to register on the road, and/or if the low odometer reading is due to the car being more of a display item in the legal sense. 22B values have risen sharply during the past decades, and the prototypes will be the most expensive.
