Audi A3

There are no engineering or handling changes to this updated A3.

As before, everything about this car is designed to deliver on the concept of a Volkswagen Golf with just a touch more polish - and the driving experience it offers is no exception.

If you're an A3 regular - or a graduate from a Golf - you'll find that this Audi has even more of the mature drive dynamics you'll be looking for, helped by a fully digital at-the-wheel experience and the optional embellishment of self-driving tech.

The original version of this MK4 model got a little more involving to drive thanks to slightly sharper steering, a wider track and the introduction of a 'modular dynamic handling control system' that, based on steering movements, predictively co-ordinates interplay between all the car's dynamic systems - like a conductor with an orchestra - so the car can always be one step ahead of the drive inputs you want to make.

The core engine options here are familiar for mainstream customers - the 30 TFSI (116PS) and 35 TFSI (150PS) petrol units and the 35 TDI diesel (also with 150PS).

Only the 30 TFSI can be ordered without Audi's familiar 7-speed S tronic dual-clutch auto transmission.

There's supple multi-link rear suspension and with the 35 TFSI petrol model, the engine comes with an integrated 48-volt 'BAS' belt alternator starter-generator that powers a 12-volt main electrical set-up in which a 48-volt compact lithium-ion battery in the boot stores energy harvested via a 'KERS' kinetic energy recovery system.

You can talk to your dealer about a highly-efficient 40 TFSI e plug-in hybrid version too, which now has a larger 25.7kWh battery capable of an 88 mile EV range.. If you've more to spend on a more sophisticated kind of A3 Sportback, you can also talk to your dealer about the 2.0-litre petrol turbo S3 variant, which gets a power hike to 333PS and the addition of the torque-splitter system previously reserved for the RS 3.

Which continues in the range, it's classic 2.5-litre five cylinder turbo engine putting out 400PS.

As before, there's a choice of Sportback hatch or Saloon versions of this fourth generation A3.

Audi's given the improved versions of both models large, angular air intakes and a flatter grille design that now features the two-dimensional four-ring logo we first saw on the brand's Q8 e-tron luxury EV.

The daytime running lights now feature up to four different illuminating signatures that owners can switch between to individualise their car's appearance. Inside, there's a redesigned centre console with an armrest, restyled air vents, a smaller (compact, flatter) auto gear selector and smarter ambient lighting (which now gives you back-lit doors and contour lights around both the centre console and cup holders).

The 'Virtual Cockpit plus' instrument screen is standard and the 10.1-inch central MMI monitor has been updated in various ways, allowing it to be customised with a wider range of applications, including Amazon Alexa.

This MMI system is permanently connected to the internet, with high speed access via an embedded eSIM, which means you can create in the car a WiFi hotspot and access things like online music streaming, online traffic information and hybrid radio.

This central screen's also your access to an audio upgrade that's now provided by Sonos, a 3D system.

As before, much effort has gone in to visually emphasise the width and spaciousness of this cabin, most notably with precise horizontal lines and surfaces.

Not all of it's smoke and mirrors; the seats have been set quite low to improve headroom, plus there's plenty of shoulder room.

This improved interior can also offer a wider range of more sustainable trimming and upholstery materials. As previously, on the rear seat a six-footer can sit behind an equally lanky driver, but it's a fairly snug fit and, as you'd expect from this class of car, three across the back here only really works if the people concerned are of school-going age.

Out back, the boot is much as before, offering a capacity of between 380 and 1,200-litres.

The PHEV version though, offers only 280-litres.

The loading floor can be adjusted to different heights, and the rear shelf can be stored underneath it to save space.

Expect pricing starting from around £29,000, with a premium of £535 for the Saloon version.

There are the usual familiar trim levels - 'Sport', 'S line' and 'Black Edition'.

All the usual executive equipment items feature and this improved A3 is even more digital and connected, thanks to numerous connect services, functions on demand, and an app store.

Standard equipment features DAB+ digital radio and a 10.1-inch central MMI touch display, along with the 'Audi virtual cockpit plus' instrument screen and an inductive smartphone charger.

In addition to the two USB-C charging ports in the centre console in the front, two additional ports in the rear also come standard. Other features include MMI navigation plus, along with the complete connect portfolio and access to the app store, which allows the driver to use a wide range of applications via the vehicle's display.

By embedding the store, customers can directly and intuitively access popular third-party apps on the MMI touch display by means of a data link in the vehicle. For our market, two individual infotainment and comfort functions can be added online via the myAudi app, even after the vehicle has been purchased.

Functions include adaptive cruise control and high-beam assist.

They can be booked for one month, six months, one year, three years, or permanently, depending on the customer's individual needs.

If, for example, a long holiday is planned with the A3, adaptive cruise assist may be a useful addition for relaxed travel on long stretches of motorway.

Audi is continuing is electrification strategy in the premium compact class, hence the emphasis on the MHEV mild hybrid 1.5-litre 35 TFSI petrol model in this A3 range.

The figures suggest that the base 35 TFSI S tronic variant manages 54.3mpg, with a CO2 return of 119g/km of CO2.

The base 30 TFSI model manages up to 50.4mpg and 128g/km in manual form - or up to 53.3mpg and 127g/km as an S tronic auto.

For the S3 petrol hot hatch, it's 33.2mpg and 193g/km. Most A3 buyers will want the MHEV auto petrol model which uses the same sort of set-up we've already seen on larger Audi models.

A 'BAS' belt alternator starter-generator that with this four cylinder engine, powers a 48-volt main electrical set-up in which a compact lithium-ion battery in the boot stores energy harvested via a 'KERS' kinetic energy recovery system.

During braking, the 'BAS' package can recover up to 12kW of power and feed it back into the battery.

If the driver takes their foot off the accelerator at speeds between 34 and 99mph, the mild hybrid system will recuperate energy, while the car rolls in idle or coasts with its engine automatically switched off for up to 40 seconds.

The belt alternator starter-generator restarts the engine the next time the accelerator is depressed, and does so faster and more gently than a conventional starter.

All of this you'll particularly notice at urban speeds where the engine start-stop system is cutting in and out.

The start stop range begins at just under 14mph, so you'll often find the car coasting up to the end of a traffic queue, a traffic light or a level crossing.

In the search for a compact car that's also a premium purchase, there are probably more charismatic choices than this Audi A3.

But we think there are few better ones.

Light in bulk, heavy in technology, it's a logical evolution of a breed that's long been one of Britain's favourite company cars.

This improved version might look little different at first glance but it might feel so once you get to grips with the upgraded interior with its two sophisticated screens.

Otherwise, things are much as before - which means that there's lot's to like.

If you're one of those still questioning the need for a premium peoples' hatch, then in this Audi, you have your answer.

From the outside, it's as home in Belgravia as it is in Brixton.

But the interior is where this design really strides apart.

You could be in a luxury car. And of course, in many ways, you are.

By pioneering the premium compact hatch segment with original versions of this model, Audi has in many ways redefined the meaning of automotive luxury, democratising it without the desirability being diluted.

Other brands claim to have done the same of course and many have used a few more visual or dynamic fireworks to grab the attention.

Ingolstadt though, doesn't think this A3 needs them and legions of loyal global buyers seem to agree.

Cool, class-less and clever, it remains desirably definitive.
