On the 2019 Geneva Motor Present Audi is presenting the plug-in hybrid variants of the A8, A7 Sportback, A6 and Q5. All these automobiles will include an electrical vary of greater than 40 km within the WLTP cycle. Due to totally different output ranges, the shopper has the selection between a consolation variant and a efficiency variant with a sporty design, relying on the mannequin collection. The brand new plug-in hybrid fashions will likely be accessible for order throughout the course of the yr 2019 in European markets.
Plug-in hybrids from medium-size SUV to luxurious sedan – Audi is increasing its vary of plug-in-hybrids for sustainable mobility. Relying on the mannequin collection, there’s a alternative of two variants with totally different efficiency and tools: A consolation mannequin and a variant with a sporty configuration with S line scopes, a extra tightly tuned suspension and drive setup with increased increase efficiency of the electrical motor for extra dynamic dealing with. Any further, the brand new plug-in hybrid fashions carry the ‘TFSI e’ signet. Sooner or later, the ‘e-tron’ label will stay reserved completely for electrically pushed automobiles.
The hybrid drive idea is designed in order that clients can journey on round a 3rd of their normal routes in electric-only mode throughout day-to-day driving. All new plug-in-hybrids by Audi use a turbo-charged gasoline engine with direct injection that works along with an electrical motor that’s built-in within the transmission. A lithium-ion battery beneath the bags compartment flooring provides power. Consequently, the electrical motor can help the combustion engine throughout acceleration.
On the similar time, with regard to recuperation, the drive system resembles that of the brand new purely electrically pushed Audi e-tron. It’s designed for top effectivity and most recuperation efficiency. When breaking, the brand new Audi PHEV fashions get well as much as 80 kW of power. The electrical motor handles slight decelerations, i.e. the bulk in on a regular basis visitors. For medium brake purposes, the duty is split between the hydraulic wheel brakes, which carry out this job alone solely with a deceleration of greater than zero.four g.
The lithium-ion battery for the A6, A7 and A8 is made up of 104 pouch cells, that are mixed in eight modules. It shops 14.1 kWh of power at a voltage of 385 V. The lithium-ion battery within the Q5 contains prismatic cells and has the identical capability. In every case, the cooling circuit of the battery is built-in within the low-temperature circuit, which provides the electrical motor and the ability electronics. The ability electronics rework the direct present of the excessive voltage-battery right into a three-phase present for the electrical motor; when recuperating, it does the other. The usual warmth pump ensures environment friendly automobile local weather management and may generate as much as Three kW of warmth power from 1 kW power with the waste warmth occurring within the automobile.
The A8 with plug-in hybrid drive has a combustion engine and a completely excited synchronous motor as an electrical motor. It’s built-in along with the clutch within the eight-gear tiptronic, which passes the torques to the quattro everlasting all-wheel drive. The luxurious liner drives as a 5.Three-meter lengthy A8 L variant with an prolonged wheelbase. The Audi A7 and A6 fashions with plug-in hybrid drive use the identical powertrain. The battery capability is similar to that of the Audi A8 PHEV. Along with the electrical motor that’s built-in within the twin clutch transmission, a gasoline engine ensures that there’s ample output and torque. Each fashions can be found in two output ranges with totally different increase efficiency. The powertrain within the Audi Q5 PHEV follows the identical idea because the Audi A6 and A7.
The plug-in hybrid fashions have the next drive modes: EV, Auto and Maintain. With the working mode button, the driving force can choose from these three fundamental settings: Precedence for the electrical drive, totally computerized hybrid mode or save energy for a later section of the journey. In “Auto” mode, the PHEVs use the clever interplay of the electrical motor and the combustion engine for max effectivity. In “Maintain” mode, the drive administration controls the powertrain in order that the present cost standing of the battery is maintained, e.g. for driving later in electric-only mode in city areas
