The Jaguar F-Type

The new Jaguar F-Type represents a return to the company's heart: a two-seat, convertible sports car focused on performance, agility and driver involvement. The F-Type is a continuation of a sporting bloodline that stretches back more than 75 years and encompasses some of the most beautiful, thrilling and desirable sports cars ever built. Joining the XK convertible and coupe models, the new F-Type provides Jaguar with a broader line of sports and GT models.







 
 
 
 
 
 
 
 

The F-Type showcases the new supercharged Jaguar engines, a 3-liter supercharged V6 in 340hp and 380hp states of tune and the 5-liter supercharged V8 in the Jaguar F-Type V8 S with 495hp and 460 ft-lbs of torque. All are equipped with the new Intelligent Stop/Start system to enhance fuel economy under certain driving conditions.

The 340hp version of the supercharged V6, which debuted in the 2013 XJ and XF sedans, produces 332 ft-lbs of torque at 3,500-5,500 rpm. The 380hp version, exclusive to the F-Type, produces 339 ft-lbs of torque at 3,500-5,500 rpm. The V8 produces an even broader torque curve, with 460 ft-lbs produced over the 2,500-5,500 rpm range.

The 340hp V6 model can accelerate from zero-to-60 mph in 5.1 seconds (0-100km/h in 5.3 seconds). The 380hp S model lowers that to 4.8 seconds (0-100km/h in 4.9 seconds), and the V8 S can hit 60 mph from rest in just 4.2 seconds (0-100km/h in 4.9 seconds).

Electronically limited maximum track speeds are 161 mph (260 km/h), 171 mph (275 km/h) and 186 mph (300 km/h), respectively, for the V6, V6 S and V8 S models.

In addition to rapid zero-to-60 acceleration, the new Jaguar supercharged engines give the F-Type outstanding merging and passing performance. The 340hp V6 model will go from 50 to 75 mph in just 3.3 seconds; the 380hp S version in 3.1 and the V8 S model in 2.5 seconds.

Based on the Jaguar 5-liter V8 engine, the 3-liter V6 shares its all-alloy construction. The lightweight die-cast aluminum block is stiffened with cross-bolted main bearing caps, increasing rigidity and refinement. A system of counter-rotating front and rear balancer weights help give the new supercharged V6 the smoothness and refinement characteristics of the V8 on which it is based.

The supercharged V6 and V8 engines combine high compression, direct fuel injection, dual independent variable cam timing (DIVCT) and a supercharger to deliver their high levels of performance and efficiency. A twin vortex supercharger is mounted in the engine's "V", and a water-cooled intercooler reduces the temperature of the intake air to optimize power and efficiency. The supercharged V6 uses a higher compression ratio than the V8, 10.5:1 vs. 9.5:1.

In both the V6 and V8, the aluminum cylinder heads package an innovative valve control system. The dual independent variable cam timing (DIVCT) system is activated by the positive and negative torques generated by the movement of the intake and exhaust valves, allowing exceptionally quick actuation rates of more than 150 degrees per second throughout the rev range.

Spray-guided direct injection delivers precisely measured quantities of fuel directly into the center of the combustion chambers at pressures of up to 150bar (2175 psi) , creating a more homogenous air-fuel mixture for cleaner and more efficient combustion. This is aided by spark plugs that are precisely indexed both in relation to the injector and within the combustion chamber.

Dacia Logan

Gaining the new styling identity of the Dacia brand, the exterior design of New Logan is more dynamic, with a more flowing form at the front. The new styling approach is most apparent in the grille and headlights, featuring a more emphatic design common to all three of the new models. The rear further emphasises Logan's robust nature with new lights and a design that showcases the spaciousness of the vehicle. The styling upgrade gives New Logan a harmonious look and an extra dose of elegance.

Dacia customers have simple and well-targeted needs. They are looking for generous, simple and reliable vehicles that are smart and affordable. Dacia's is a practical offering that responds perfectly to the expectations of its customers.
Marketing an increasingly wide range of vehicles (Logan, Logan MCV, Sandero Stepway, Duster, Lodgy, Dokker, Dokker Van), Dacia is posting remarkable quality results. In the latest 2012 results of ADAC, the benchmark German organisation, the reliability of Dacia vehicles has improved continuously over the last three years and Sandero is number four in its category. In February, the brand ranked number-one on reliability in a survey carried out with 30,000 customers by consumer organisations in Belgium, France, Spain, Italy and Portugal.
Dacia builds durably reliable cars and is winning the trust of its customers
Dacia vehicles, like Renault ones, are tested in the most extreme conditions. In addition to conventional bench tests, the Renault group puts its vehicles through demanding tests in real-world conditions to confirm their durability. Logan, for example, was tested over 1.9 million kilometres. Dacia cars are designed from the outset to be sold internationally, and notably in emerging markets. They are developed according to demanding specifications given the diversity of road and weather conditions in such countries.
All Dacia models are covered by a 3 year/60,000 miles manufacturer warranty, with service at all dealerships in the network and top-level repair expertise with manufacturer parts. The warranty is targeted at winning new customers, raising awareness of the brand, and building a relationship of trust with customers.
Dacia benefits from the quality expertise of Renault, which has become a leading carmaker on reliability, largely the result of a global group quality policy launched in 2003.
Dacia relies on Renault group and Alliance know-how in standards and processes
New Logan, Sandero and Sandero Stepway will be produced at the Pitesti plant in Romania and the SOMACA plant in Casablanca, Morocco for the regional market (including Morocco and Tunisia). Starting in the second-half of 2013, New Sandero will also be produced at the Tangier plant in Morocco.
