The brand with four rings has released details regarding its completely revised 1.8 TFSI engine, which will be fitted in the updated Audi A5 family. The turbocharged four-cylinder gasoline unit comes as the base engine for Europe, and is capable of delivering 170 horsepower and 320Nm of torque, while returning a fuel consumption figure of 5.7L/100km. This means consumption has been reduced by 21 percent compared with the previous model engine. The revised A5 emits just 134g of CO2 per km. Coupled with a manual transmission, the 1.8 TFSI accelerates the Audi A5 Coupe from zero to 100 km/h in 7.9 seconds on its way to a top speed of 230 km/h .

TC engines are about torque@rpm figures. No point flexing all the hp figures w/o looking at the overall car package.

Let's look at the torque figures:

Audi 1.8L TFSI: 320Nm @ 1400rpm ~3700rpm

Merc 1.8L TC: around 310Nm @ 2200rpm

BMW 2.0L TC: 270Nm @ 1250rpm (I know this is not apple to apple, but it's close)

In terms of acceleration and throttle response, you can see Audi & BMW is almost instant. For the Merc you got to push the 1.8L NA to 2200rpm before you feel the boost kicks in. IMO it's a far cry from the other 2 engines.

What can I say? I'm not a hp guy like most ppl. It's all in the twisting power call torque.

Why does Audi 'still have some catching up to do'? This engine looks really impressive overall and I doubt any of the other brands' 1.8s can match its fuel efficiency.

  • Space: Large and Empty

    Over the weekend I fell into a bit of a science-fiction/science rabbithole. You know, one of those when you click on ONE Youtube video and suddenly the whole Sunday afternoon is gone and your algorithm is all messed up.  Anyway, obviously there's tons of fascinating stuff about space and science and all that. Too much, really.  But one fun fact has stuck in my brain: All the other planets in the Solar System could fit between Earth and our Moon.  It seems crazy to think, consideri

    This should be the true Singaporean national dish

    Singapore is known to be a melting pot of different cultures, races, people and of course, cuisines from all over the world. You can probably find food from most places here in Singapore, but we also have some dishes that we like to think of as our national dish - okay, google says there isn't an officially declared national dish, but Chicken Rice is one of those that's often mentioned. Yes, we all love Chicken Rice, but it isn't really unique to Singapore.... Nasi Lem

    Big things are funny things

    Being anywhere tangentially close to current affairs news right now is deeply depressing. In so many ways, the world seems like it's going to s*it.  In a bid to escape all that and cheer myself up a little, I've been recently amused and moderately infatuated with randomly huge things. Here are just a couple that make me chuckle:  Yup, the world's largest chair. I also find the name of the company, XXXLutz, incredibly funny and more than a little blue.  Otto the ot

    Tennis: Beautiful game that doesn't know how to count

    Wimbledon just concluded yesterday (congrats Sinner!), and it's a reminder of how much I enjoy tennis as a sport. I used to play it some (wasn't particularly good), and still tangentially follow it nowadays (the Roland Garros final this year between Alcaraz and Sinner is an all-time classic).  There's something intrinsically mesmerising about the sport, I think even for spectators who have never picked up a racquet. At first glance, it may seem like just two people (or four, but doubles is
