Audi has just announced that they will be offering a new four-cylinder for the A5 family. The new engine is a 1.8L TFSI four-banger that’s good for 170hp and 236 lb-ft of torque and is lighter, smaller, and more efficient than the outgoing version.
Featuring the usual jargon including Audi’s and Volkswagen’s familiar FSI direct-injection system, the new 1.8L engine also uses port-injection for partial-load and throttle situations.
The results for the A5 are 0-60 times of about 7.9 seconds and an average fuel-economy cycle of 41.27 mpg, which means that the 1.8L consumes on average 21% less fuel than the outgoing engine.
Also featured on this new engine is a fully electronic cooling system. This means that the water pump was exchanged for two fast-switching rotating cores, which are consolidated into one unit and driven electronically by a small motor. The new cooling system is designed to make the A5 more efficient by making better use of the heat produced as a byproduct from the engine. So this also means cold starts will be easier than ever.
