Tråd: Fire-pot motor for entry-level Jaguar F-type

Test muldyr viser Jaguar ' s planer om at udstyre sine F-type sportsvogn med en turboladet fire-cylindret benzinmotor. Dette Jaguar F-type konvertible menes at være en ingeniør, udvikling af en prototype for en Jaguar Land Rovers alle de nye fire-cylindret turboladet motor.
Bilen er ikke blot har en lidt anden motorhjelm, med en let hævet center sektion, men det er også klart har en prototype udstødningssystemet.
For en fire-cylindret motor med sin mangfoldige på kun den ene side, et nyt udstødningssystem skal være konstrueret og detaljeret arbejde, såsom optimering af modtryk, skal udføres.
F-type køretøj linje direktør Ian Hoban blev citeret for at sige der var sidste år en lang række powertrains og transmissionsløsninger, der kunne monteres i F-type arkitektur. Hoban sagde han så stort potentiale i montering af en high-output Turboladet fire-cylinder motoren til F-type.
Jaguar har aldrig før bygget en fire-cylindret sportsvogn (selv om der var planer om en fire-cylindret udgave af XK120), men den nye generation af Hotfire turboladede motorer er habil i ekstremt høj effekt og drejningsmoment output.
En fire-cylinder F-type bliver lidt lysere generelt end de V6-drevne versioner. Det bør også drage fordel af forbedret smidighed, fordi Hotfire motoren vil sidde yderligere tilbage i biler næse og lægge mindre vægt over forhjulene, mens brændstoføkonomien forbedres mærkbart.
En fire-pot F-type er imidlertid usandsynligt, at ankomme før sent 2015. JLR engineering direktør Wolfgang Ziebart siger de første pre-produktion Hotfire motorer vil være diesel og vil rulle ned linjen på den nye i54 fabrik i foråret. Han hævder også, den nye motorfamilie vil fastsætte benchmarks med hensyn til effektivitet, vægt og effekt.
Når den er fuld-skala produktion af den nye motor begynder i slutningen af dette år, alle motorer vil være dieselmotorer til den nye kompakte Jaguar sedan, som vil blive lanceret i Europa, før den når benzin-venlige AMERIKANSKE marked.
Som et resultat, en post-niveau F-type er usandsynligt, at blive annonceret, før Frankfurt motor show i September 2015.

Test mule shows Jaguar's plans to equip its F-type sports car with a turbocharged four-cylinder petrol engine. This Jaguar F-type convertible is thought to be an engineering development prototype for Jaguar Land Rovers all-new four-cylinder turbocharged engine.
The car not only has a slightly different bonnet, with a gently raised centre section, but it also clearly has a prototype exhaust system.
For a four-cylinder engine with its manifold on only one side, a new exhaust has to be designed and detail work, such as optimising the back pressure, has to be carried out.
Last year F-type vehicle line director Ian Hoban was quoted as saying there was a whole host of powertrains and drivelines that could be fitted into the F-type architecture. Hoban said he saw great potential in fitting a high-output turbocharged four-cylinder engine to the F-type.
Jaguar has never before built a four-cylinder sports car (although there were plans for a four-cylinder version of the XK120), but the new generation of Hotfire turbocharged engines is capable of extremely high power and torque outputs.
A four-cylinder F-type will be slightly lighter overall than the V6-powered versions. It should also benefit from improved agility, because the Hotfire engine will sit further back in the cars nose and put less weight over the front wheels, while fuel economy should improve noticeably.
However, a four-pot F-type is unlikely to arrive before late 2015. JLR engineering director Wolfgang Ziebart says the first pre-production Hotfire engines will be diesel and will roll down the line at the new i54 factory this spring. He also claims the new engine family will set benchmarks in terms of efficiency, weight and power.
When full-scale production of the new engine begins at the end of this year, all the engines will be diesels for the new compact Jaguar saloon, which will be launched in Europe before it reaches the petrol-friendly US market.
As a result, any entry-level F-type is unlikely to be announced before the Frankfurt motor show in September 2015.
