On the Tonale SUV i first hybrid engines in Alfa Romeo historywith two electrification levels available: Hybrid And Hybrid plug-in. The main heat engine is i 1.5 Turbo Stellantis which goes to equip the new Fiat and Jeep models, which has already debuted on the new ones Renegade and Compass Hybrid. On the Tonale, however, the power is greater and reaches 160 hp on the Hybrid version and a 275 on the Plug-In Hybrid.
New Alfa Romeo hybrid and plug-in hybrid engine
The Hybrid VGT (Variable Geometry Turbo) engine makes its debut exclusively for Tonale 130 or 160 hp. This version is equipped with front-wheel drive and one new hybrid technology which includes a propeller 1.5 petrol with variable geometry turbo compressor combined with automatic transmission double clutch seven-speed Alfa Romeo TCT with electric motor “P2” 48 volt of 15 kW and 55 Nmcapable of transmitting motion to the wheels even when the internal combustion engine it’s off.
The transmission in fact allows you to leave and move in electric mode at low speeds, when maneuvering parking area and undergoing sailingguaranteeing on paper the typical performance of a petrol engine but with consumption (petrol + electric) comparable to that of a diesel engine with extremely linear power delivery and particularly brilliant acceleration.
Alfa Romeo 1.5 hybrid engine, as it is made features
The new 4-cylinder turbo engine has been designed to best adapt to the hybrid application and optimize thermodynamic efficiency and therefore fuel consumption.
Among its peculiarities, the functioning according to the Miller cyclethe high compression ratio (12.5: 1), the new cylinder head with compact combustion chamber, double phase variator and specific high turbulence intake ducts. The high pressure direct injection systemwhich reaches 350 bar.
Turbo new Alfa Romeo hybrid engine
The version from 160 hpdesigned exclusively for Alfa Romeo, adds a new turbo supercharger with variable geometry capable of combining great responsiveness at lower revs and high power for a sportier ride, all while maintaining a high level of efficiency.
A belt starter generator which ensures rapid and silent transitions when restarting. Furthermore, the Intelligent Brake System optimizes the ‘autorecharge’ functionality: in fact, thanks to the regenerative braking mixedthe recovery of thekinetic energy during deceleration, to the advantage of efficiency.
Alfa Romeo Tonale hybrid, driving mode
Driving the Alfa Romeo Tonale hybrid, the driver can choose between different driving modes to optimize performance, including:
- “Silent Start” which makes it possible to start and start the vehicle without starting the petrol engine, using the “EV” mode
- “Energy Recovery” which recovers energy that would otherwise be wasted while the car decelerates (e-Coasting) and during braking (Regenerative Braking);
- Boost & Load point shift. Thanks to “e-Boosting” it is possible to increase the torque at the wheels with the electric motor that supports the petrol engine; furthermore, by calibrating the torque (driving or braking) delivered by the electric motor, it is possible to optimize the operating point of the petrol engine;
- Electric Drive which allows the vehicle to travel using the electric motor while the petrol engine is off.
In particular, there are numerous driving situations in which the new Tonale can take advantage of the solo electric motor (then proceed with the petrol engine off), thanks to the numerous EV functions:
- e-Creepingby means of an electric motor, it provides the cue normally available on cars with automatic transmission, with the vehicle speed that can vary between 0 km / h and that equivalent to the minimum of the petrol engine in first gear or in reverse;
- e-Launchallows the vehicle to start with only the help of the electric motor;
- e-Queuingallows you to move through congested traffic following a “stop & go” flow;
- e-Parkingwhich makes parking maneuvers practical and silent.
