The new Qashqai brings the first deployment of Nissan's innovative e‑POWER drive system to Europe. Exclusive to Nissan and a key component in the company's Intelligent Mobility strategy, the e-POWER system is a unique approach to electrification by making every day driving exciting.

The new Qashqai's e-POWER system is comprised of a high-output battery and powertrain integrated with a category-leading variable compression ratio 157PS petrol engine, power generator, inverter and 140kW electric motor of similar size and power output as found in Nissan's electric vehicles. It's a unique solution that combines the enjoyable, seamless linear acceleration which is characteristic of an EV, but without the need for charging.

To meet the typical demands of European consumers and their daily drive, the e-POWER installation has been significantly upgraded for the new Qashqai. Where the application in the Note - Japan's best-selling car in recent years – is a 1.2 petrol engine charging the battery unit, and a final power output of 108PS. For Europe it has been upgraded to a 1.5-litre petrol engine, with a final power output of 140kW (190PS).

The unique element of the e-Power is that the petrol engine is used solely to generate electricity, whilst the wheels are completely driven by the electric motor. This means the engine can always run within its optimal range, leading to superior fuel efficiency and lower CO2 emissions compared with a traditional internal combustion engine.

"The e-POWER system offers the best transition technology between ICE and EV, allowing users to enjoy exhilarating EV driving sensations and impressive efficiency at an affordable price point. We're really looking forward to customers experiencing the thrill of new Qashqai's superior electrified driving performance – it's a perfect expression of Nissan Intelligent Mobility," said David Moss, Region Senior Vice President Research and Development, Africa, Middle East, India, Europe and Oceania (AMIEO).

Thanks to the pure electric motor drive, there's no delay as with an internal combustion engine or traditional hybrid. The instant 'EV like' response delivers exhilarating high torque feel and best level acceleration at different speeds to make overtaking or merging onto a motorway easier and more confidence-inspiring.

There are three driving modes on e-POWER versions: Standard, Sport and Eco. In Standard, the car produces excellent acceleration and lift-off regeneration is tuned to simulate the engine-braking of a conventional petrol vehicle. In Sport mode, the car further improves acceleration response with reduced engine off time, especially in sporty driving scenarios. In Eco, the car goes into fuel-saving mode by optimising battery management and allowing the driver to select a coasting model for economical highway driving. In all modes an additional B mode can be selected which increases the energy recuperation at lift-off, slowing the car more efficiently without the use of the brake pedal.

The new Qashqai with e-POWER not only accelerates quicker than hybrid rivals, but does so with a lower engine RPM. The system operates very quietly, much like a full EV, and is tuned for the best level of quietness and connected feeling when accelerating, thanks to a focus on keeping relationship between engine RPM and road speed connected.

Similar to the LEAF, the new Qashqai e-POWER benefits from an entirely new 'one pedal' driving experience called e-Pedalmode. Drivers can start, accelerate and decelerate using only the accelerator pedal, supporting up to 90% of driving scenarios.

In stop-and-go urban driving conditions, e-Pedal mode significantly reduces the need to move your foot from one pedal to the other by providing up to 0.2G of deceleration when lifting off the accelerator. This makes driving simpler and more relaxing. In order to optimise e-Pedal for parking manoeuvres, creep has been added and the brake pedal must be used to stop the vehicle. On open, winding roads, e-Pedal provides a more engaging drive whilst reducing the need to depress the brake during cornering.

Drivers can monitor the energy flow of e-POWER on the 12" TFT meter to check the system state.

Nissan's e-POWER system was introduced to the Note and Serena models in Japan. An immediate success in terms of customer popularity, more than 70% of Note sales and almost half of Serena sales in the country are e-POWER versions. Indeed, the recently launched Nissan Kicks compact SUV equipped with e-POWER has just been awarded the 2021 Technology of the Year award by the Automotive Researchers' and Journalists' Conference of Japan.

 "Since 2007, when it invented the segment, the new Qashqai has always set the standard in the crossover segment. With the third generation Qashqai, new and existing customers are going to love the innovative powertrain options available to them. Our offer is simple and innovative, with both powertrain options being efficient, but still fun to drive. Our approach to the new electrified Qashqai has been without compromise and that is clearly evident with both the 1.3 petrol, with mild hybrid technology and the unique e-Power option," said Matthew Wright, Vice President, Powertrain Design and Development, Nissan Technical Centre Europe.

Sales of the new Nissan Qashqai equipped with e-POWER will begin in 2022

 

 

 

 

Non essendoci un Scelte Strategiche Nissan metto qua: dal 2030 tutti i modelli in gamma Nissan saranno ibridi (o elettrici)

 

https://it.motor1.com/news/482307/nissan-dal-2030-solo-auto-ibride-elettriche/

 

Per Nissan, e-POWER non è solamente la denominazione commerciale del sistema full hybrid adottato nei suoi veicoli, ma è anche il nome di una delle chiavi della strategia di elettrificazione delle suo auto che, assieme alle EV denominate "Zero Emission" e ad altri importanti accorgimenti di contorno (innovazione sugli accumulatori, uso degli stessi come sistemi d'accumulo per le rinnovabili "intermittenti" ed un efficace sistema di riciclo/riuso dei veicoli/componenti a fine vita), condurrà il marchio verso la tanto ricercata "Carbon neutrality".

 

Come si può vedere a partire dalla slide n. 6, da qui al 2030, secondo Nissan l'ibridazione massiva avrà un ruolo importante per il marchio, sia per il numero di vendite globali, che in termini di contributo nel raggiungimento dell'obiettivo finale (concreto abbattimento delle emissioni).

 

Nella slide n. 10, Nissan confronta le emissioni medie nel corso dell'intero ciclo di vita di varie tipologie di veicoli (benzina, ibridi e-Power ed elettriche) attualizzate alla tecnologia contemporanea. I "rettangoli tratteggiati" invece, sono la stima del risultato della riduzione di CO2 sul ciclo di vita delle auto, ricorrendo alle future tecnologie in sviluppo dal marchio nipponico. 

 

Saltando a pag. 19, Nissan esplicita chiaramente come, con il raggiungimento dell'ambito traguardo del 50% di efficienza del sistema propulsivo, possa portare i loro veicoli ibridi e-Power ad un impatto ambientale medio (nell'intero ciclo di vita) pari a quello delle loro EV. Questo quantomeno durante la fase di transizione (almeno una decina di anni) verso un più tangibile mix di energie rinnovabili (o prive di emissioni dirette, come il nucleare, aggiungo io) ed il miglioramento delle tecnologie per un massiccio ricorso al riciclo e riutilizzo dei materiali/componenti dei veicoli dimessi.

 

Segue una serie di slide circa le tecnologie e focus tecnici su cui Nissan si concentrerà per raggiungere il 50% di efficienza nei sistemi termici. Tra queste, viene evidenziata la chiave di successo dell'attuale stato della tecnologia ibrida e-Power, ovvero la possibilità di di utilizzare il termico in punti di lavoro ottimali. 

Nelle rimanenti slide (dalla 11 alla 17), si parla di come stia evolvendo e come evolverà la tecnologia delle EV Nissan e dei punti di convergenza con la tecnologia ibrida e-Power, sintetizzando: elasticità di marcia, confort acustico, facilità di guida (one pedal) e recupero energetico.

 

 

Alla fine allego anche il video della presentazione da cui ho estratto le slide a mio avviso più interessanti, buona consultazione!  

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Penso che questa slide vada bene non solo per Nissan, ma anche per tutte le case in generale.
Dopo il 2030 la propulsione delle auto sarà quasi esclusivamente elettrica, anche se molte genereranno a bordo l’elettricità con la benzina.
