Audi A4 B9 vs B10
Two generations, eight model years apart. The B9 closed out the combustion-first era of the A4; the B10 opened the PPC platform chapter. We put both on the same set of figures and looked at what the newer car actually gives you.

Die Entwicklung in 30 Sekunden
Die acht Änderungen, auf die es ankommt — vor allen Details
Platform moves to PPC
MLB evo gives way to the Premium Platform Combustion architecture, shared with the next A5 and Q5.
MLB evo → PPCMild hybrid across the range
Every petrol and diesel now carries a 48 V system as standard; on the B9 it was reserved for the six-cylinder cars.
MHEV standardLarger, sharper infotainment
The recessed 10.1-inch panel is replaced by a free-standing 11.9-inch screen angled toward the driver.
10.1″ → 11.9″Longer, and heavier for it
The body grows 67 mm, and the hybrid hardware and extra insulation add 75 kg over a comparable B9.
+67 mm · +75 kgConsumption falls despite the weight
WLTP combined drops by 0.6 l/100 km, recovered through the mild-hybrid system and a lower drag figure.
−0.6 l/100 kmMore power at the entry point
The base petrol gains 13 PS, which is most of the reason the 0–100 figure improves at all.
+13 PSReworked single-frame grille
The familiar frame stays, now with a three-dimensional pattern that changes with the lighting angle.
Redesigned frontSlightly smaller boot
Packaging the battery under the floor costs 15 litres of luggage space — the one figure that moves the wrong way.
−15 l

Fazit
Bewertet nach den Werten oben, nicht nach Markentreue
Still the pragmatic pick. Physical controls, a manual option on the used market, and a price that has already taken its depreciation hit.
Quieter, more efficient and better equipped, but you pay for it up front and give up 15 litres of boot and every physical climate control.
Umsteigen, wenn
- You drive enough kilometres a year that 0.6 l/100 km actually shows up on the fuel card.
- You want the current assistance package — the B9's hardware cannot be retrofitted.
- Cabin noise matters to you; the laminated glass is a genuine, measurable difference.
Bleiben, wenn
- You load the boot to the roof regularly — the B9 gives you 15 litres more and a flatter floor.
- You want physical climate dials, which the B10 does not offer at any trim level.
- You are buying used and the €4,600 list-price gap has not yet closed on the second-hand market.
Häufige Fragen
Is the B10 A4 faster than the B9?
On the entry engine, marginally: 8.5 seconds to 100 km/h against 8.9. The gap comes from the mild-hybrid system's electric boost rather than from extra displacement.
Did the A4 lose its manual gearbox with the B10?
Yes. The B9 offered a six-speed manual on lower-output petrols; the B10 is S tronic only across the entire range, in every market.
Why is the newer A4 heavier?
The 48 V mild-hybrid hardware, the larger body and additional sound insulation add roughly 75 kg over a comparable B9.
Is the B9 still worth buying used?
For high-mileage buyers who want physical controls and a lower entry price, yes. The B9 has already absorbed its steepest depreciation, and its running costs are close to the B10's outside of fuel.
