What type of engine does the Audi S4 use?
What Powerplant Powers the Audi S4? A 3.0 liter turbocharged V-6 engine with 349 horsepower and 369 lb-ft of torque powers the S4. The S4 completes the 0-60 mph sprint in 4.2 seconds while using an eight-speed automatic transmission to route output to the quattro AWD system that is standard.
Audi S4: Is it turbocharged?
The S4 has a powerful 3.0-liter V-6 engine with supercharging that produces 333 horsepower and 325 lb-ft of torque. A six-speed manual transmission is the default, although a seven-speed dual clutch automatic transmission is also an option. Through Audi’s quattro system, power is distributed to all four wheels.
Audi S4: Is it a V-6?
For many customers looking for a luxury mid-size sedan or wagon, the Audi S4 can be the ideal compromise. It’s not the full-fat hardcore RS4 that costs around 50% more, but by no means is it a “average” A4.
This is due to the 3.0 liter turbocharged gasoline V6 engine that powers the S4 and has enormous outputs of 260 kW and 500 Nm. It includes an eight-speed automatic transmission and Audi’s “quattro” all-wheel drive system as standard features, as well as several performance upgrades that improve suspension, aerodynamics, and attractiveness.
The Audi S4 is offered as a sedan for $101,500 and as an Avant station wagon for $107,500.
Which V8-powered Audi is this?
The 2018 Audi RS 7 is an illustration of the brand’s V8-powered mid-size luxury vehicles. The A6 premium sedan served as the ancestor of the RS 7, which later underwent a sporty liftback body style transformation into the A7. The high-performance version of the A7 is the S7, and the RS 7 amplifies the excitement even more. The 4.0-liter turbocharged V8 engine in that particular model offers drivers 605 horsepower, 516 lb-ft of torque, and a 0-60 acceleration time of 3.6 seconds. A list of luxurious standard features that includes heated Valcona-leather front sport seats, carbon fiber inlays, and a multi-function steering wheel with a flat bottom is very appealing.
The S4 went turbo when?
The best-performing model of the Audi A4 lineup in 2008 was the S4. It was unveiled as a 2009 model in late 2008, replacing the 4.2-liter normally aspirated V8 with a 3.0-liter supercharged V6.
With the release of the S4, the Audi’s battle for horsepower came to an end. The German automaker used the adage “less is more” to its A4 line, taking it for granted. By adding a light fixture,…
Is the Audi S4 turbo or supercharged?
The 3.0-liter V6 engine powering the 2018 Audi S4 is turbocharged as opposed to supercharged like its predecessor. In comparison to the supercharged engine, this produces 21 more horsepower and, more significantly, 44 more pound-feet of torque, totaling 354 horsepower and 369 pound-feet. Audi claims that 60 mph will be reached in just 4.4 seconds when paired with the eight-speed automatic transmission from ZF, yet the engine is still effective enough to achieve decent EPA-estimated fuel economy ratings of 21 mpg city and 30 mpg highway.
The drivetrain is excellent when pedaling vigorously in Dynamic mode, with no noticeable turbo lag. With peak torque ranging from 1,370 to 4,500 rpm and constant thrust, it is possible to accelerate quickly out of curves and away from stoplights. The transmission’s gear shifts are swift and precise in full automatic mode, but a manual mode is also available for those who prefer a more engaging driving experience. The only drawback to choosing your own gears is the cheap-feeling plastic steering wheel paddles.
I regret to inform you that there will not be a manual transmission. 2018 sees the end of the six-speed stick that was offered in earlier S4s. The only available transmission right now is the automatic. You can whine all you want, but Audi decided against producing three-pedal S4s due to insufficient demand. Sad, I know. The eight-speed auto, though, works perfectly.
How quickly can an Audi S4 travel?
In Germany, I witnessed an APR-tuned S4 traveling at roughly 185 mph. She’ll easily reach 155 mph, so I’d estimate at least 170 mph. This past weekend, I took a short road trip and was pleasantly impressed by how steady and manageable the car felt at 120130 mph.
Which engine powers the 2012 S4?
Exterior The style is different from the A4’s, just like early S4 models, yet it isn’t overdone. The performance variant would be unnoticed to the untrained eye. It has new bumpers and a new grille, as well as 18-inch wheels with performance tires and a trunk lid with an integrated spoiler. The S4 insignia may be seen on the brake calipers. The front and rear diffuser blades of the S4 have metallic “aluminum-optic highlights, and it has four tailpipes. features on the outside include:
- For the Premium Plus model, 18-inch wheels
- Prestige model with 19-inch wheels
- Headlights with Xenon high-intensity discharge and LED daytime running lights
- heated, auto-dimming side mirrors
Interior The A4 lacks many features featured in the S4, including a black headliner, brushed aluminum trim, and a choice of carbon fiber, wood, or stainless steel. The S4 stands apart by having contoured sport seats and a number of other features. The steering wheel, doorsills, gauge cluster, and remote control all sport S4 insignia. Interior characteristics include:
- Engine start and keyless entry
- Bluetooth connectivity for hands-free phones
- upholstery made of leather and Alcantara as standard
- Silk Nappa leather upholstery is optional.
- optional backup camera and navigation system
- Optional premium stereo by Bang & Olufsen
- common iPod integration
Within the Hood The 3.0-liter V-6 supercharged engine in the S4 generates 325 pounds-feet of torque and 333 horsepower. Both a six-speed manual and a seven-speed automated manual transmission are available, with the latter having two clutches for quick gear changes. It has an automated mode and steering wheel paddles that allow manual shifting. the following mechanical features:
V8 Timing Chain Failure
The timing chain links the crankshaft and camshaft and regulates how the intake and exhaust valves of the engine open and close. This technique utilizes a hydraulic tensioner to keep the chain taut in addition to guides that hold the chain in place. A timing chain cover that bolts to the block surrounds the chain, keeping it lubricated and shielded from road grime.
Timing chains on 4.2 V8 engines frequently break. First off, chains need to be replaced because they naturally expand with time. The chain should typically last the whole life of the vehicle, but excessive engine heat buildup and irregular oil changes can shorten its lifespan.
Plastic is used to make the chain guides. Due to their close proximity to the block, they are constantly vibrating and heated. The plastic guides may crack as a result of this. Furthermore, if the tensioners malfunction, the chains will get slack and may jump teeth.
The 4.2 V8’s timing chains commonly break before the 100,000-mile mark and have even broken at 50,000 miles.
V8 Timing Chain Failure Symptoms
- cylinder malfunctions
- 17748 and P1340 engine codes
- the engine is rattling
- Slouch mode
The cam and crank gears typically begin to jump teeth when the timing chain fails. This alters engine timing and causes numerous misfires. The pistons and valves may collide if the chains leap too many teeth, severely damaging the internal engine components.
Timing Chain Replacement Options
Because timing chains fail, the Audi 4.2 V8 receives a very negative reputation for dependability. Although this is a highly frequent issue, it only accounts for a portion of the engine’s poor reputation.
The timing chain on the Audi 4.2 V8 is situated on the back side of the engine, as opposed to the front, where it is mounted on other vehicles. Because of this, replacing the timing chain requires pulling the entire engine, which takes a lot of time.
Furthermore, the components themselves are pricey; a complete timing chain repair kit costs over $4,000. Once labor is added, the cost of a replacement project rises to $8,000 or more.
Make careful you change your oil periodically to avoid timing chain breakdown. Regardless matter how frequently the factory recommends changing the oil, we advise doing it every 5,000 miles.
V8 Carbon Buildup
A direct-injected engine is the 4.2 V8. Gasoline injectors are used in direct injection engines to spray fuel right into the combustion chamber. Port injection is a direct injection substitute. Port injection involves spraying fuel into the intake manifold, which it passes through before passing through valves and into the combustion chamber.
The fuel passing through the manifold and valves during port injection helps clean them of accumulated crud. However, with direct injection, no highly pressurized gasoline is traveling through the manifold and valves to assist clean them out because the fuel is sprayed directly into the combustion chamber.
As a result, carbon buildup, a gunk-like substance, coats the intake manifold and valves. The intake system and valves will gradually become clogged by these lingering carbon deposits. This limits airflow and can cause a number of performance problems.
Removing Carbon Buildup
Carbon accumulation occurs over time. Except for misfires and rough idling, these symptoms frequently go unnoticed because the performance usually declines gradually over time. Even while carbon accumulation won’t result in any significant engine issues, we nonetheless advise cleaning the intake ports and valves every 80,000100,000 miles.
By the time you reach this distance, the valves and ports will have accumulated quite a bit of buildup. Cleaning them will undoubtedly improve performance and eliminate any sluggishness, bringing the automobile back to life a little.
The best way to get rid of carbon buildup is by using a technique called walnut blasting. By blowing numerous tiny walnut shells into the intake ports and valves with a shop vac, walnut blasting removes all of the buildup.
Preventing Carbon BuildupAudi 4.2 V8
While carbon buildup cannot be eliminated entirely, it can be minimized and its rate of accumulation slowed.
- every 5,000 miles, replace your oil and filter.
- Install a catch can for oil
- Clean your ethanol fuel injectors.
- Use only 93 octane or higher fuel.
- Drive occasionally for 20 to 30 minutes at a high speed on the highway.
V8 Variable Valve Timing Failure
Variable valve timing, sometimes known as VVT or Vanos, is a feature of Audi’s V8 engines. The system variable changes the camshaft’s position, allowing for more accurate timing of the intake and exhaust valves.
The system uses a VVT Solenoid to regulate the timing of the camshaft, which is triggered by oil pressures. These solenoids frequently develop clogs or buildup, which can lead to failure and result in timing and performance-related engine problems.
Is the 4.2 V8 an effective motor?
The 4.2-liter V8 is another weird option for a dependable old Audi engine. On the one hand, it is highly regarded by Eurosport Tuning and Ward’s Auto. However, it was utilized by the problematic B7- and B6-gen S4s.
Similar to the EA888 engines, the 4.2-liter Audi V8 is plagued by complaints about timing-chain tensioner failure. Like the EA888, enhanced replacement parts are also accessible, according to RSW. More importantly, newer vehicles with this engine, like the RS5, R8, and B8 Audi S5, don’t appear to have this problem. The S5, R8, RS5, Q7, A6, and A8 tensioners are all designed differently, according to FCPEuro, which may account for this.
Which S4 is the fastest?
Recently, Canada beat the record for the fastest Audi S4 B8 in the globe. The Audi S4 is already a quick car, but with a few AWE Tuning parts, they may undoubtedly become much faster.
According to AWE, Jeff Jones’ Audi S4 is the quickest S4 in the world after reaching the benchmark time of 11.61 seconds at 119.12 mph (191.8 km/h) on Saturday. The factory-built 2012 Audi S4’s 3.0-liter supercharged V6 engine generates 245kW and 440Nm. You can bet your last dollar that this extensively modified S4 produces more more than 245kW even if neither Jeff nor AWE have disclosed its exact power output.
The Audi S4 has received upgrades like a touring edition exhaust, B8 3.0T resonated downpipes, an AWE Tuning stage 2 pulley kit with G.I.A.C. stage 2 performance software, a ColdFront heat exchanger, a ColdFront coolant pump, a ColdFront reservoir, and G.I.A.C. S-Tronic gearbox software. All of the aforementioned enhancements are available for purchase through AWE Tuning’s website.
As you can see from the picture, Jones also changed the suspension to have a lower and more hunkered-down stance and found a new set of wheels that are more suited for racing. He stated:
“I’ve driven nearly 20,000 miles with the AWE Tuning/GIAC Stage II upgrade. It is not only very powerful but has also shown to be quite dependable and fun all year long. My final pass of the day, which came after more than ten straight passes, was my best pass.
What Audi models have turbochargers?
The 3.0T supercharged V-6 has made an appearance in the engines of seven distinct Audi models: the S4, S5, A6, A7, A8, Q5, and Q7. This engine is employed in the VW Touareg, the Porsche Cayenne, and the Panamera, so Audi drivers aren’t the only ones who like it.
