What is the difference between Audi A4 35 TFSI and 40 TFSI?
Performance and Engine Options The standard engine option for the A4 is the 35 TFSI, a 2. PS. You can expect a combined mpg of 45. CO2 emissions of 141 g/km. Overall a fairly average offering from Audi. The second petrol option is the 40 TFSI, again a 2. PS. The 2025 Audi A4 offers two powertrains: the 40 TFSI, with a turbocharged 2. TFSI, delivering 261 horsepower from an enhanced version of the same engine. Both powertrains feature all-wheel drive and a seven-speed dual-clutch automatic transmission.Audi offers the A4 in two strengths: 40 and 45. Both are powered by a turbocharged 2.Its 40 TFSI four-cylinder engine produces 201 horsepower and still achieves up to 34 mpg on the highway, even with Quattro all-wheel drive. TFSI works by precisely injecting fuel directly into the combustion chamber at optimal times, maximizing both performance and efficiency.TFSI stands for “turbo fuel stratified injection” and is used by Audi to describe its innovative gasoline engine technology. It ensures precise fuel distribution, optimum combustion, and maximum engine power.
What does 40 TFSI stand for?
TFSI stands for ‘Turbo Fuel Stratified Injection’, a technology synonymous with Audi’s petrol engines since its introduction in 2004. This advanced fuel injection system is designed to ensure precise fuel distribution, which maximises engine power while significantly enhancing fuel efficiency. Audi TFSI stands for Turbo Fuel Stratified Injection and is a petrol engine technology that blends the best elements of direct fuel injection technology with turbocharging. This unique Audi powertrain was the first turbocharged direct injection engine on the market when it was first introduced in the A3 back in 2004.TFSI stands for ‘Turbo Fuel Stratified Injection’. It is the name Audi has given to its petrol engines, which use an innovative petrol engine technology.TFSI. This engine is part of Audi’s modular 90° V6/V8 engine family. It shares its bore and stroke, 90° V-angle, and 90mm cylinder spacing with the Audi V6. The earlier V6 engines (EA837) used an Eaton TVS Supercharger instead of turbocharger(s).Audi TFSI stands for Turbo Fuel Stratified Injection and is a petrol engine technology that blends the best elements of direct fuel injection technology with turbocharging. This unique Audi powertrain was the first turbocharged direct injection engine on the market when it was first introduced in the A3 back in 2004.Like many modern direct-injection engines, the 1. TFSI engine in the Audi A4 B9 is prone to carbon buildup on the intake valves. In direct-injection engines, fuel is injected directly into the combustion chamber, meaning it does not pass over the intake valves to clean them.
What is the difference between 35 TFSI and 40 TFSI?
The Audi A4 35 TFSI and 40 TFSI use the same 2. PS in the 35 TFSI and 204 PS in the 40 TFSI, as well as additional torque. The standard engine option for the A4 is the 35 TFSI, a 2. PS. You can expect a combined mpg of 45. CO2 emissions of 141 g/km. Overall a fairly average offering from Audi. The second petrol option is the 40 TFSI, again a 2. PS.There’s a new badging structure too, which kicks off with the ’40 TFSI’ variant we’re going to look at here. It uses the 2.Arguably chief amongst the revisions, however, was an upgraded plug-in hybrid powerplant badged 40 TFSI e, that employs the latest Volkswagen Group 1.Its 40 TFSI four-cylinder engine produces 201 horsepower and still achieves up to 34 mpg on the highway, even with Quattro all-wheel drive. TFSI works by precisely injecting fuel directly into the combustion chamber at optimal times, maximizing both performance and efficiency.Well, the 148bhp 35 TFSI needs to be worked fairly hard to build speed, which is why we prefer the 201bhp 40 TFSI (the best option if you don’t want a diesel).
What is 40 vs 45 TFSI?
The larger the number attached to TFSI, the larger the engine. Hence, why you will normally see 25, 30, 35, 40, 45, 50, 55 and 60 alongside TFSI, expressing where the engine sits in the range, and giving indication to its power. The 35 TFSI models have an output of 110kW and 250Nm of torque from their 1. TFSI models have 140kW and 320Nm coming from their 2. It’s easy – one is a 1.
Is 40 TFSI hybrid?
Arguably chief amongst the revisions, however, was an upgraded plug-in hybrid powerplant badged 40 TFSI e, that employs the latest Volkswagen Group 1. The 1. TFSI engine relies on its turbocharger to deliver the responsive performance drivers expect from a small-displacement engine. However, turbocharger and wastegate problems are common, particularly as the vehicle accumulates mileage.Accolades: The 4. TFSI V8 engine has gained acclaim for its robust power output, solidifying its reputation as a high-performance powerhouse. Its seamless integration of TFSI technology contributes to a driving experience that is both powerful and refined.The result of higher compression ratio and better knock suppression is the reason the TFSI engine is one of the best tuneable engines in the world, awesome part throttle light load response which moves quickly into a strong broad torque band which hols well creating amazing area under the power curves.Accolades: The 4. TFSI V8 engine has gained acclaim for its robust power output, solidifying its reputation as a high-performance powerhouse.
Is TSI or TFSI better?
Although the Volkswagen TSI is technically superior, both the TSI and TFSI are reliable engines. Despite their issues, both engines are known to last longer than 200,000 miles if maintained with care. TSI’ stands for Turbocharged Stratified Injection and is a type of turbocharged petrol engine that Volkswagen produces. Based on the TFSI (Turbocharged Fuel Stratified Injection), the TSI model is upgraded to improve reliability and everyday drivability.Audi TFSI stands for Turbo Fuel Stratified Injection and is a petrol engine technology that blends the best elements of direct fuel injection technology with turbocharging. This unique Audi powertrain was the first turbocharged direct injection engine on the market when it was first introduced in the A3 back in 2004.TSI engines are designed to offer more horsepower and torque without compromising fuel economy, making them a popular choice among drivers who want both performance and practicality. TDI refers to Turbocharged Direct Injection, a technology used in Volkswagen’s diesel engines.
