Audi is providing the revamped A4 with many engine choices outfitted with 12V and 48V mild-hybrid programs (MHEV). This additionally applies to the Audi S4 TDI (mixed gas consumption 6.three – 6.2 l/100 km (37.three – 37.9 US mpg); mixed CO2 emissions 166 – 163 g/km (267.2 – 262.three g/mi), with a diesel V6 TDI beneath the hood for the primary time, a 48-volt primary electrical system and an electrical powered compressor (EPC).
Audi S4 Avant TDI
Audi will supply the A4 mannequin line with six turbocharged engines at gross sales launch in Europe. Their energy outputs vary from 110 kW (150 PS) to 255 kW (347 PS) – from the Audi A4 35 TFSI (mixed gas consumption 6.zero – 5.5 l/100 km (39.2- 42.eight US mpg); mixed CO2 emissions 138 – 125 g/km (222.1 – 201.2 g/mi) as much as the Audi S4 TDI (mixed gas consumption 6.three – 6.2 l/100 km (37.three – 37.9 US mpg); mixed CO2 emissions 166 – 163 g/km (267.2 – 262.three g/mi). All engines—whether or not the four-cylinder diesel unit, V6 TDI or four-cylinder TFSI—undercut the bounds of the Euro 6d-temp emission commonplace.
For the market launch three engine variants will function a mild-hybrid system (MHEV) based mostly on 12 volts, which reduces gas consumption whereas enhancing consolation. (Earlier submit.) In on a regular basis use, the MHEV system reduces gas consumption by as much as zero.three liters per 100 kilometers in accordance with particular person Audi measurements.
Whether or not guide transmission, seven-speed S tronic or eight-speed tiptronic, whether or not front-wheel or quattro drive—every of the six engine variants delivers tailored energy transmission. All A4 fashions come off the manufacturing line with an computerized transmission as commonplace.
The sportily balanced suspension ideally harmonizes with the character of the Audi A4. Clients can select between the usual setup and the game suspension. There are additionally two adaptive suspensions. One choice is the consolation suspension with damper management, which reduces the trip peak by 10 millimeters (zero.four in) and gives excellent trip consolation. The opposite is the game suspension, both with or with out damper management, which is lowered by 23 millimeters (zero.9 in). With its much more dynamic primary setup, it underscores the sporty character whereas sustaining consolation. Each managed suspensions are built-in into the Audi drive choose dynamic dealing with system. The identical applies to the steering, with dynamic steering, the automated transmission and the throttle valve obtainable for patrons as an choice. Audi drive choose permits the motive force to find out which of as much as 5 profiles these programs use.
Diesel and 48V delicate hybrid. Each S fashions of the A4 household—the Audi S4 Sedan TDI (mixed gas consumption 6.three – 6.2 l/100 km (37.three – 37.9 US mpg); mixed CO2 emissions 164 – 163 g/km (263.9 – 262.three g/mi) and the S4 Avant TDI (mixed gas consumption 6.three l/100 km (37.three US mpg); mixed CO2 emissions 166 – 165 g/km (267.2 – 265.5 g/mi)—at the moment are outfitted with a V6 diesel engine as an influence package deal.
The three.zero TDI combines hefty torque, clean operating and an extended vary and supplies an influence output of as much as 255 kW (347PS) and most torque of 700 N·m (516.three lb-ft). It accelerates the S4 Sedan TDI from zero to 100 km/h (62.1 mph) in four.eight seconds on the way in which to an electronically ruled high pace of 250 km/h (155.three mph). This mix of energy, torque and effectivity makes the Audi S4 TDI distinctive within the section.
The electrical powered compressor delivers highly effective drive-off efficiency and nearly seamless energy buildup when accelerating. As such, it eliminates any turbo lag, offering on the spot responsiveness in all driving conditions. The electrical powered compressor is built-in into a brand new 48-volt primary electrical system, which additionally incorporates the mild-hybrid system.
This supplies much more effectivity potential than the MHEV system within the 12-volt electrical system on the A4 fashions. Within the S4 TDI that is the following enlargement stage by which the mild-hybrid know-how might be rolled out based mostly on 48 volts.
The 12-volt subsidiary electrical system is linked to the 48-volt primary electrical system through a robust DC/DC converter. For the primary time a robust 48-volt belt alternator starter is getting used within the S4 TDI as the center of the mild-hybrid system with a most recuperation energy of as much as eight kW when braking.
A compact, air-cooled lithium-ion battery with a capability of zero.5 kWh, which is positioned beneath the bags compartment flooring, acts as an vitality administration middle. The mild-hybrid system on the S fashions has the potential to scale back buyer gas consumption by as much as zero.four liters per 100 kilometers.
An eight-speed tiptronic and the quattro everlasting all-wheel drive make up the drivetrain. If desired, an non-obligatory sport differential is accessible to actively distribute energy between the rear wheels. On this approach, extra energy could be directed particularly to the wheel on the skin of the bend when cornering at pace, which combats the tendency to understeer early on. The S sport suspension is commonplace. With its S-specific setup it supplies a sporty driving sensation. This may be enhanced even additional with the non-obligatory S sport suspension with damper management.
The Audi A4 fashions and the S4 fashions with a TDI engine and sporty new look could be ordered in Europe from Might 2019. The A4 allroad quattro might be obtainable within the early summer season and each fashions might be within the dealerships from fall 2019.
Audi gives the S4 and the S4 Avant with the three.zero TFSI in markets outdoors Europe. The turbocharged gasoline direct injection engine has an output of 260 kW (354 PS) and produces torque of 500 N·m (368.eight lb-ft) from 1,370 to four,500 rpm. The V6 accelerates the S4 Sedan TFSI from zero to 100 km/h (62.1 mph) in four.7 seconds on the way in which to an electronically ruled high pace of 250 km/h (155.three mph). The usual dash takes two tenths of a second longer within the S4 Avant TFSI.
