30% more torque

In addition to the current twincharged (turbo + supercharger) 170hp and 140hp TSI engines, this third engine is the newest addition to the TSI lineup. It retains the same 1.4 liter iron crankcase as the larger TSI engines, however, it is not twincharged since it loses the supercharger but keeps the turbo. Set to replace the current 1.6 FSI engine (85 kW / 115 hp), the new TSI engine at 122hp (90 kW) makes 200Nm of torque, 30% more than the 1.6 FSI, and reduces fuel consumption by 6 percent. Torque curve is impressive by achieving 80% maximum torque at 1250 rpm and then holding 100 percent torque from 1500 rpm to 3500 rpm. Full details in the press release below.

Overview

TSI Engine Offensive

  • New TSI with 122 PS: Economical and Powerful

  • Economical: New TSI consumes six percent less fuel

  • Powerful: Maximum torque of 200 Nm in reserve at a low 1,500 rpm

Maximum power with minimum fuel consumption - this characteristic has, within a very short period of time, made TSI four-cylinder engines a synonym for a new generation of economical and at the same time sporty Volkswagen engines. Performance specifications: 125 kW / 170 PS and 103 kW / 140 PS. The Golf, Golf Variant, Golf Plus, Jetta and Touran are powered by them. In 2006 and once again in 2007 they were awarded the coveted "Engine of the Year Award". Now Volkswagen is presenting the third TSI; this one is 90 kW / 122 PS strong and will be introduced to the Golf lineup this year.

The new TSI will replace the 1.6 FSI with 85 kW / 115 PS in the mid-term. Decisive advantages of the new turbo engine: Besides being able to reduce fuel consumption by about six percent, the engine's power and torque characteristics were also improved significantly. Due to its smaller displacement, vehicle taxes are also lower. Compared to the 1.6 FSI, maximum torque has now been increased by nearly 30 percent to 200 Newton-meter. And this power is already available at 1,500 rpm. In addition, 80 percent of the maximum torque is already available at speeds as low as 1,250 rpm. In the lower speed range the TSI even exhibits Newton-meter gains of up to 66 percent compared to its predecessor.

Another plus when it comes to economy: Since its maximum torque is available over a broad speed range from 1,500 to 3,500 rpm, conditions are ideal for combining the new TSI with longer and therefore fuel-saving gear ratios. That is why in the future Volkswagen is planning to pair it with the first transverse seven-speed dual clutch transmission in the world (DSG). Its debut will also be in 2007.
