    Rumorpile: Jaguar F-Type Coupe To Come Available With 700 Horsepower

    File this under the highly speculative folder. This past week Auto Express reported that Jaguar is planning to do R-S version of their new F-Type. The F-Type R-S is expected to come in a coupe form initially and pack a 700 horsepower engine that can make the F-Type R-S reach a top speed of over 200 MPH.

    Here's where's it goes of the rails somewhat. Auto Express says one way Jaguar could achieve this is use some of the technology from the canned C-X75 hybrid supercar; a 1.6L turbo- and supercharged four-cylinder engine and an array of electric motors.

    Auto Express says the F-Type R-S will arrive in 2016.

    As long as it is under warranty all is good, but the moment the warranty runs out, plan on thousands of dollars in cost each year to replace all the crazy electrical mess or the blown engine.

    I do not see any long term life out of this mess, but just a short term excitement by those rich enough to afford this bleeding edge experiment.

    Take a Z1 over this mess any day.

    The 5.0L AJ133 supercharged engine in the V8 F-type is the same motor as in the XF Supercharged, XFR, XFR-S and XK cars making between 470 and 550 hp (mostly due to bleed valve regulation*). Featuring dual VVT, a cam switching VVL system (2800 rpm switch over from low lift to high lift lobes), direct injection and an Eaton TVS supercharger. It's not a bad engine -- smooth, unexpectedly fast revving (for a X-plane V8) and decent on fuel economy (15/21 mpg; 15/23 mpg on the 8-speed cars). The Ratan Jaguars are also quite reliable compared to the old ones. There is no Lucas anything in there. The engine management systems are largely Ford. From a reliability and cost of ownership standpoint, I'll take an XF, XJ or F-type over any BMW M-car (especially the E60 M5 any day).

    In any case, getting 700 hp out of a 5.0 liter blown motor isn't hard. Just don't expect 15/21 mpg when you enlarge the blower, drop the compression and go to a higher rated ZF gear box.

    * You can run the XKR-S ECU file on the XF S/C and go from 470 hp to about 520~530, without changing anything else. I know first hand :)

      Back in November, we first learned about Mercedes-AMG's next standalone model possibly known as the GT4, a four-door coupe. The new model would be previewed by a concept before going on sale in 2019. We now have some new details on this model.
      Autocar reports the GT4 concept will be shown next month at the Geneva Motor Show to celebrate the 50th anniversary of AMG. A production model will soon follow a year later for European markets.
      The GT4 will serve as the replacement for the CLS Shooting Brake and use a modified version of Mercedes' modular rear architecture (MRA). According to sources at AMG, the GT4's variant of MRA will come with 'unique' wheelbase and track width measurements. The GT4 will also utilize aluminum and hot-formed high-strength steel in an effort to help cut weight.
      Power will come from a 4.0L V8 biturbo engine that will be offered in two states of tune - the highest one offering 600-plus horsepower. A performance-oriented version of Mercedes' 4Matic all-wheel drive will come standard. There is also talk about adding integrated starter generator (ISG) that would add a brief boost of power along with improving fuel economy.
      A 3.0L turbocharged V6 is possibly in the cards as well.

      How much is Opel worth? According to Bloomberg, the valuation being discussed by General Motors and PSA Group puts it around $2 billion dollars. According to sources, the total comprises about $1 billion in cash and about $1 billion in liabilities. The amount could change as two are still assessing a number of items such as the value of brand rights and savings potential.
      The sources also the framework for PSA to buy Opel could be finished by Thursday. This would be the same day when PSA Group reports full-year earnings. The sources go on to caution this could be pushed back because of the complex nature of the deal such us finding ways to reduce costs while keeping workers and the various unions happy.

      A new report from Auto Express says Jaguar's Special Vehicle Operations (SVO) is putting the finishing touches on high-performance XE to take on the likes of the Alfa Romeo Giulia Quadrifoglio, BMW M3, and Mercedes-AMG C63.
      The XE SVR will boast Jaguar's 5.0L supercharged V8 engine with around 500 horsepower. This will be hooked up with an eight-speed automatic. The current SVR lineup - F-Type and Range Rover Sport - utilize all-wheel drive and there is the possibility the XE SVR could go down this route. There has also been some work done on the chassis with new springs, dampers, and a limited-slip rear differential. Expect a more aggressive exterior look to go with the mechanical changes. 
      Auto Express says the XE SVR "will arrive almost halfway through the saloon’s lifecycle," leading us to believe it could be next year or so.

      I have one co-worker who has been a thorn in my side for the past 6 months.... but I have to admit that when I need something done that is in his area of expertise, he goes after it like an angry rabid chihuahua and gets it done.
