Offering improved performance, efficiency and lower fuel consumption, the innovative twin dry clutch semi-automatic transmission ALFA TCT is now available to order on the five-door Alfa Giulietta hatchback.
Equipped with the next-generation ALFA TCT semi-automatic transmission and optional shift paddles behind the steering wheel, the latest Alfa Giulietta offers a benchmark in its class in terms of performance, fuel consumption and emissions. Available with either the 1.4 TB MultiAir 170 bhp petrol (International Engine of Year Award ‘Best New Engine 2010’) or the 2.0 JTDM-2 170 bhp diesel engine, the ALFA TCT range increases the Giulietta’s appeal in both the fleet and consumer sectors.
The sporty credentials of the 1.4 TB MultiAir 170 bhp Giulietta with ALFA TCT transmission result in a car capable of a top speed of 135 mph and 0 to 62 mph time of 7.7 seconds. Even with this excellent performance, the fuel consumption and emissions are extraordinary low; 54.3 mpg over a combined cycle and 121 g/km of CO2 – values that make the Giulietta lowest CO2 emitting car of any petrol engine in the C segment* – and with a BIK rate of only 15%.
The values recorded in combination with the 2.0 JTDM-2 170 HP diesel engine are also outstanding: in fact, compared to the same version with manual gearbox, acceleration from 0 to 62 mph drops from 8.0 seconds to 7.9 seconds, fuel consumption (combined cycle) decreases from 60.1 mpg to 62.8 mpg, while CO2 emissions are just 119 g/km (124 g/km with manual gearbox), resulting in a BIK rate of just 13%.
In terms of all-round consumer appeal, the Alfa Giulietta offers drivers the complete package; class-leading five-star Euro NCAP safety rating, competitive finance offers, three years unlimited mileage manufacturer warranty, three years AA cover and up to five years or 50,000 miles complimentary servicing. This focused consumer offering has helped the marque finish in the Top Ten of the independently conducted J.D. Power and Associates 2011 UK Vehicle Ownership Satisfaction Study (VOSS), and seen Alfa Romeo UK record the industry’s largest year-to-date market share increase of 55.26% in September.
Available to order now at Alfa Romeo dealerships – alongside the sporty compact Alfa MiTo 1.4 TB MultiAir 135 bhp ALFA TCT which was launched earlier this year – the Alfa Giulietta 1.4 TB MultiAir 170 bhp ALFA TCT and the 2.0 JTDM-2170 bhp ALFA TCT are available in Lusso and Veloce trim levels, with prices starting from £21,855 OTR.
About ALFA TCT transmission
The operation of the ALFA TCT transmission is distinguished by maximum interaction with the vehicle’s systems. To achieve the best performance on the road depending on driving conditions and on the driver’s requests, the semi-automatic transmission interacts with the braking, engine control, Alfa D.N.A. vehicle dynamic control switch, Start&Stop, steering and vehicle stability control systems.
Thanks to the speed with which the parameters are processed, the transmission can modify the speed of gear shift, manage the torque delivery on low grip roads, and it can operate completely automatically or as a manual sequential gearbox, manually managing the up and down positions of the gear lever with precise and ergonomic movements, which can be combined with optional shift paddles behind the steering wheel.
Developed by FPT – Fiat Powertrain Technologies, in conceptual terms the new ALFA TCT transmission consists of two gearboxes in parallel, each with its own clutch, which allows the selection and engagement of the subsequent gear while the previous one is still engaged. The gear is therefore changed with a simple gradual switch of the corresponding clutches, guaranteeing continuous torque delivery and therefore traction.
The result is a driving comfort and sporty feeling far superior to those offered by conventional automatic transmissions (with torque converter), as proven by greater speed of gear shift, the possibility of selecting between manual or automatic mode, and a near-zero power loss during the gear change. In addition, the purchasing, servicing and running costs are low, while fuel consumption is reduced, thanks also to the implementation of the Start&Stop system, by up to 10% compared with a traditional automatic hydraulic transmission with torque converter.
Other notable features of the new ALFA TCT are its flexibility of application, thanks to the compact size of its components, and the fact that it is a dry twin clutch (the type of clutch that guarantees the highest degree of efficiency in terms of fuel consumption among all automatic transmissions).
If we compare dry clutches with oil bath (wet) clutches, we can safely say that the former dissipate energy only during the actual slipping phase of the gear change and on pick-up, whereas wet clutches, which always operate in an oil bath, introduce losses due to viscous friction such as those of conventional automatic transmissions, even when they are not in operation. They also require forced cooling with oil, and therefore continuous energy expenditure to drive the dedicated oil pump (absent in the case of dry clutches).
A ‘wet’ automatic transmission also requires approximately 4.8 litres more gearbox oil than the dry version, again for reasons of clutch cooling (in this way, weight is added and losses due to splashing increase). When all these effects are added together, a dry transmission is found to be approximately 6% more efficient than the corresponding wet one in terms of consumption.
