Audi A6 hybrid range, MPG, CO2 & charging
The Audi A6 TFSI e is efficient, but its electric range isn't quite as long as rivals'
|Fuel economy||CO2 emissions||Electric range||Wallbox charge time|
|141-188mpg||35-45g/km||34 miles||2hrs (0-100%, 7kW)|
Plug-in hybrid executive cars such as this have to offer enough electric range for the average commute, as well as reasonable fuel economy on longer motorway journeys. The A6 lives up to both of these requirements, with official figures comparable to those of equivalent BMW and Mercedes models.
It pays to remember that you're highly unlikely to get anywhere near the official fuel-economy figures. In normal driving, you're more likely to see two-figure returns, somewhere between those of a conventional petrol-engined A6 and a diesel. To maximise efficiency, it's best to keep the battery topped up, travel on electric power as much as possible and avoid strong acceleration.
However, with the average 40% taxpayer saving over £4,000 a year compared to the Benefit-in-Kind payable on an equivalent petrol-only A6, fuel costs are unlikely to be a big concern.
Audi A6 plug-in hybrid range, MPG & CO2 emissions
The Audi A6 plug-in can travel a claimed 34 miles on a single charge with no help from its petrol engine. This should be more than enough for most shorter commutes, but it's not quite as good as the BMW 530e (up to 37 miles) or Mercedes E 300 e (32 miles). And in real-world driving, we only got about 25 miles from the Audi.
Official fuel-economy figures vary depending on specification, with the smaller-wheeled Sport version the most efficient. Its official consumption is 166 to 188mpg, while the slightly heavier and larger-wheeled Vorsprung range-topper returns 141 to 149mpg. It's the same story with CO2 emissions, with the Sport maxing out at 39g/km, versus the top-spec car's 45g/km.
The Audi A6 50 TFSI e can charge at a maximum speed of 7kW, which equates to around two hours for full replenishment from a compatible home wallbox or public charger. Audi remains tight-lipped about official charging times but as a rough guide, a full charge from a three-pin domestic socket should take around six hours, or four hours from a 3.7kW wallbox.
In This Review
- 1VerdictAudi was late to the plug-in hybrid party with its A6 50 TFSI e, but it's a decent enough crack at a tax-efficient large company car
- 2Range, MPG, CO2 & charging - currently readingThe Audi A6 TFSI e is efficient, but its electric range isn't quite as long as rivals'
- 3Running costsThe Audi A6 TFSI e makes most sense as a company car – the running-costs savings elsewhere are less impressive
- 4Engines, drive & performanceThe A6 TFSI e is a smooth, refined and powerful saloon car, but it's not as engaging to drive as its BMW 530e rival
- 5Interior & comfortInside, the Audi A6 TFSI e is large, comfortable and spacious, plus it has a great infotainment system
- 6Practicality & boot spaceThe Audi A6 TFSI e is big enough inside to seat four adults in supreme comfort, but boot space is less than in the purely petrol or diesel versions
- 7Reliability & safetyAudi hasn't performed as well as you might expect for reliability of late, but the A6 TFSI e should be a very safe car
