What is it?
The 1.4 TFSI is the entry-level model of the ground-up new Audi A4 range. It’s based on Audi’s new MLB-Evo platform and is claimed to weigh as much as 120kg less than the outgoing model. The drag coefficient of 0.23 is said to be lowest in class.
The car has grown in size, being 25mm longer (12mm of the stretch is in the wheelbase) and 16mm wider. This is to the benefit of cabin space, especially in the rear. Knee room is particularly impressive for rear passengers, while the front seat occupants have a satisfyingly capacious cockpit.
This ‘totally new’ 148bhp petrol engine replaces the old 1.8 TFSI unit, although it is less powerful. It’s a sophisticated unit, which has its exhaust manifold integrated into the cylinder head, very high-pressure (200bar) fuel injection and separate cooling circuits for the crankcase and cylinder head.
The engine is mated to a six-speed manual gearbox. Unfortunately the 1.4 TSI isn't offered with Audi's new automatic seven-speed S tronic dual-clutch automatic transmission.
The entry-level A4 1.4 TFSI SE model costs £25,900 on the road. Notable standard-issue features include xenon headlights with LED running lights, three-zone climate control, switchable damping, automatic city braking, keyless go, stop-start and cruise control with a ‘freewheeling' mode.
In the UK, pay another £950 for this Sport model and you’ll also get sat-nav, 17in wheels, extendable squab sports seats, an upgraded sound system and a nice three-spoke steering wheel.
What's it like?
The new A4 can best be described as a polishing of the established A4 formula, rather than a reinvention. Much of the car’s story revolves around fuel efficiency and the introduction of some autonomous technology, such as the automatic city braking.
The remarkable fuel-saving coasting function, which uses information from various on-board sensors to suggest to the driver that he lifts of the throttle, uses the car's kinetic energy - rather than its fuel - to carry it along.
Audi has also taken a conscious decision to tune the new A4 more for comfort than hard-core handling prowess. Indeed, Audi chairman Rupert Stadler told Autocar that customer requests had been for a more ‘comfort-orientated’ car.
On the roads north of Venice, this A4 is just that: a free-rolling, long-legged and somewhat languid driving companion. It is certainly comfortable and swift at motorway speeds, showing unexpected real-world ground-covering ability for a relatively modest powertrain.
The gearshift is very smooth and slick, although the lever is quite tall and the throw long. This biggest problem in making super-smooth progress is at lower speeds, where the difficulty of finding the clutch's biting point on its featherweight pedal action is a hurdle.
This car has the Audi ‘Drive Select’ system, which offers three settings: Comfort, Auto and Dynamic. There’s no need to experiment, just select Dynamic and leave it there. The Comfort setting is a mystery. It leaves the A4 underdamped and unable to track straight and true at motorway speeds.
