According Hengding automobile hub unit noted , Jaguar F-TYPE is a front-engine rear-wheel drive two-seater sports roadster , which will launch F-TYPE, F-TYPE S and F-TYPE V8 S three models .
● lightweight body design
Features: aluminum body structure completely riveting and bonding processes.
Make a car lighter and faster than it seems to make it more meaningful , but for a performance sports car , the weight and speed are complementary , to ensure the structural integrity of the body at the same time , if we can further optimize its own weight , speed and control of the vehicle which the performance will have a positive effect. Jaguar engineers understand this before F-TYPE models have not yet launched their luxury cars already use aluminum body structure technology , on this basis , F-TYPE be further optimized transformation.
- Aluminum body and process optimization on the Jaguar F-TYPE controlled vehicle weight 1597 kg .
Body structure F-TYPE 's completely riveting and bonding process , they use a special type of high-strength AC300 smelting aluminum in higher resistance to impact strength , while the quality can be well controlled , because of so , F-TYPE white body weighs only 261 kilograms ( Audi A5 COUPE models BIW weight of 283 kg ) .
It is worth mentioning that, compared with other Jaguar models, to make lighter , F-TYPE to use more synthetic materials , such as car parts are produced by the threshold of high- strength plastic made , optimized engine hatch and seats were reduced 12 kg and 24 kg . Further , in the production process is also considered in this respect , the windshield , the sensor portion and the associated cooling system in which both reduce the weight of the engine and the bumper support member 5 kg lighter respectively , after optimization of the transmission system is reduced by 8 kg , but the curb weight , F-TYPE models still reached 1597 kg , the same level compared to the Porsche product , in this regard F-TYPE to be inferior or more ( 2013 Porsche Boxster S 3.4 models the curb weight is 1350 kg ) .
- The application of special materials to match the shape of the lines sketched .
In order to achieve the desired design language , in addition to the body structure is made of alloy material , but in some cover , Jaguar also introduced aluminum siding, unlike the former , the use of this aluminum siding is in order at the same time ensure the robustness , you can get a higher plasticity to demonstrate a clear close lines, compared to the conventional technique , the surface of the bonnet line F-TYPE models can be sketched out greater curvature of the lines, thus creating a great piece of exotic face shape .
● headliner on / off will affect the body weight ratio after it?
In my mind there is a problem throughout failed to get an answer , take advantage of this opportunity to wish and it throws everyone to be explored.
Hard top / soft top convertible roof after opening , the center of gravity of the vehicle will change, and that the vehicle handling limit will not be affected? Or look at this issue from another angle , manufacturers in the design of a hard top / soft top convertible car , what is the state of the roof to be opened chassis tuning , or pay more attention to handling the roof off of it ? Compared to the hardtop convertible , weighing slightly less Drophead open roof open or after the impact is bound to be smaller. This will not give special consideration to the Jaguar F-TYPE engineers in the design to make it ? After all, a sense of luxury hardtop convertible looks stronger, of course, this is only our speculation , however , in extreme driving conditions , subtle differences will be hugely magnified , but, at the Jaguar F-TYPE conceal it as much as possible .
Or , in the adjustment at the beginning, more Drophead convertible preference for state control performance , because the soft top hood light weight , even when you close the roof , the vehicle handling is not the limit state have much of an impact , while the hardtop convertible roof is more emphasis on handling performance when closed , and once the roof receive the trunk , its original weight ratio will be broken front and rear wheels and therefore subject to greater pressure , so that , in the corners , the rear wheels of the limit will come sooner.
● 3.0 liter supercharged engine technology
Features: engine uses aluminum material, supercharged and direct fuel injection system of mutual collaboration.
● Who is the partner ? Matching 8 -speed automatic transmission
In the new power unit, Jaguar will be upgraded gearbox , the original six -speed automatic transmission upgraded to a 8 -speed automatic gearbox, the new gearbox supplied by ZF (ZF). ZF 8- speed automatic transmission was named 8HP series , which originally developed the most important goal is to reduce fuel consumption, gear ratio by more intensive , more efficient shift actuator torque converter control the size , transmission structure, optimize the design weight makes eight -speed automatic transmission in the size and volume of the ZF 6-speed automatic transmission is quite the case , than the six-speed automatic transmission reduces fuel consumption by 6% . If the match is a hybrid system , this gearbox can reduce fuel consumption by up to 25% .
- Structural Design : 6 -speed automatic transmission with a considerable size
Ratio change mechanism of this ZF 8 -speed automatic transmission consists of four groups of five planetary gears and clutch constitute the core of the shift in the torque converter application of new technology , and enable them to quickly lock , reducing the power loss of the torque converter .
Gearbox oil pump arranged in parallel using chain drive design, the length of the box 8AT control, plus the compact design of the clutch and planetary gear set , and ultimately achieve a six-speed automatic transmission with a considerable volume .
Design and development through precision solenoid valves and control systems , ZF eight -speed automatic transmission shift control in less than 0.4 seconds of time , depending on the requirements of OEMs , this ZF 8 -speed gearbox You can also support faster shift speeds.
● gear ratio final drive gear set
Features: V6 supercharged engine equipped with two models in the tooth than the main gear reducer has a different setting .
Equipped with a supercharged V6 engine two models not only data on the engine tuning is different than on the final pass setting also vary , gear ratio F-TYPE V6 S models is 3.31:1 final drive gear , and gear ratio F-TYPE V6 models , compared with 3.15:1 final drive gear , that is, the acceleration response , V6 S models will be faster , but in the same gear when traveling at the same speed , V6 S engine speed is higher.
● Jaguar F-TYPE models are equipped with a limited slip differential
Features: equipped with a supercharged V6 engine models equipped with a mechanical limited-slip differential, and equipped with a V8 engine F-TYPE is equipped with electronic limited slip differential .
F-TYPE S and F-TYPE V8 S between the two models are equipped with a limited slip rear differential, but the difference is , F-TYPE S assembly is a mechanical limited-slip differential, as is what type , we have to wait for further technical information can be determined. The F-TYPE V8 S is a multi-plate clutch is used to achieve the speed difference between the two wheels in extreme conditions.
F-TYPE V8 S such an electronic limited slip differential and driving stability system and ABS anti-lock braking systems work with each other , through information collected from a comprehensive analysis and calculation will eventually control commands sent to the relevant executive mechanism , e.g. , when the vehicle rear wheels slipping , the outer wheel grip break occurs idling , if not limited, not only by the power loss will be , and will gradually increase the degree of skidding and eventually beyond the control of the driver , sitting 495 hp F-TYPE V8 S seems to be more agile need a limited slip differential system with multi-plate clutch mutual electronic limited slip differential on both sides of the wheel and brake calipers can make two rounds of inter- faster wheel side slip to limit the speed difference occurs when the slip side of the wheel brake while the clutch ipsilateral , thereby transmitting power to the good adhesion of the inner wheel , which can help the driver better control the body posture . So, even sitting 495 horsepower , F-TYPE V8 S will be very easy to build trust and a good driver .
F-TYPE models are equipped with the V6 engine in the Jaguar is already the third generation of the family , which uses aluminum structure, in order to improve the structural strength of the engine components in the optimization of manufacturing processes is made , for example , rely bolted bearing cap on the use of cross -style bolt connections , not only reinforces the strength of the process is also more refined .
- Fuel injection system
Five in the role of high pressure piston pump , injectors spray fuel from the pressure up to 150Bar said under such pressure , droplet diameter of only the human body hair ( say may be hair ) diameter one minute, in order to improve the efficiency of fuel combustion .
- Engine running smoothness and variable valve timing system
In order to improve the smooth operation of the engine , a lot of engineers in the design of the cylinder to be installed beginning to consider the balance shaft and its mounting location and surrounding aside other auxiliary components , the use of a counterweight to offset balance shafts on the rotation of the crankshaft and vibration generated by the piston up and down the line , on examination, this approach is very successful . This 3.0-liter supercharged engine also ingested the same concept, but it is more balanced system architecture design is simple , that is only in the front end of the crankshaft counterweight each installation of a block by block interleaving two balanced opening angle V -type engine to compensate vibrations generated during operation .
DIVCT (Dual independent variable cam timing) variable valve timing system can be controlled by making VCT actuator valve timing between the chain and there is a certain time lag , in a sense, this time difference is nonexistent , and when when camshaft adjustment mechanism includes the ability to rotate 150 degrees per second , in that small space , a relatively slow time of both , the intake and exhaust side of the valve can be done to take this opportunity to adjust the phase angle , so that you can ensure whether the engine is at low speed under high load have a high respiratory rhythm.
● Unlike the previous supercharger
