Audi S4 Avant TDI driven: turbodiesel sports-wagon tested

# data.attributes.metatag[].attributes.content
Yum, a new Audi S4. A classic ‘all the car you’ll ever need’.Always has been. The S4 is one of the world’s last Q cars. Subtle looks, but enough punch to see off a Cayman. Big space, with neat’n’tidy handling. Lots of pace, in all weathers. It’s never the first car you park in the Dream Garage, but even if you had an underground bunker brimmed with Bugattis and Paganis, you’d use an S4 more days than a platinum-plated Lambo-segg.And now it’s powered by diesel fuel?

# data.attributes.metatag[].attributes.content.reviewBody[]
doesn’t it? Audi was caught just as red-handed as its Volkswagen parent in the dieselgate emissions-dodging scandal of 2015 and beyond. The UK has responded by shunning diesel cars faster than evicted Love Island contestants. So far in 2019

diesel’s share here has shrunk by almost 20 per cent

compared to 2018. And it tanked in 2018 too…So

# data.attributes.metatag[].attributes.content.reviewBody[]
why is Audi still banging the diesel drum?Because it sees a future in cars that have deep reserves of torque to punt them along

# data.attributes.metatag[].attributes.content.reviewBody[]
and emit less CO2 than a car with a petrol habit

# data.attributes.metatag[].attributes.content.reviewBody[]
while travelling further on a tank. Torque is much more useful in The Real World than peaky top-end power. Especially in a roomy family wagon. Sounds familiar? They’re the reasons that Europe fell painfully in love with TDIs in the first place. And still quite compelling

any diesel that sunk below 50mpg would’ve been a laughing stock.

really. There’s a vaguely six-pot rumble in the middle distance when you clog it. It sounds more expensive than a four-cylinder diesel by a mile

but hardly justifies brandishing four polished tailpipes.Then again

# data.attributes.metatag[].attributes.content.reviewBody[]
the old petrol V6 was hardly a vocal event. At times

that’s been compensated for by a simply biblical wallop of torque. In the old car
