The most interesting thing about the new Audi A2 is what Audi did not change. Autogefühl confirms the car sits on the MEB platform and carries the same three battery options as the VW ID.3, a car that has been on sale since 2019. There was no new cell chemistry to announce and no packaging breakthrough to point at. So the engineering went somewhere else. Across the three reveal videos the aero work is the recurring subject: air curtains, an active front shutter, a covered underbody and, in Electrifying's account, a diffuser running almost the full width of the rear, all of it aimed at the 0.24 drag coefficient every one of them quotes. When the pack is fixed by the platform you share, the only range left to find is in the shape of the thing pushing through the atmosphere.
That is a narrower lever than it sounds, and Electrifying is honest about the limits of it. The presenter notes the Skoda Enyaq coupe already manages 0.22, so 0.24 is good rather than exceptional, and points out the new car has grown roughly half a metre longer than the original A2 in the process. Aerodynamics bought Audi a claimed 397 miles WLTP from the big pack. It did not buy back the small, light car people remember.
The same trade showed up this week in a driveway in San Diego. Two Bit da Vinci and a friend took their houses fully off the grid for 48 hours during the hottest stretch of the year. Ricky's house had 68 kilowatt hours of battery and fell to 16 percent on the first night. Adam's had 30 and never dropped below about 40 percent, with the air conditioning running the whole time. Ricky's own explanation, in the video, is that Adam has a modern inverter heat pump and a well insulated house while his own HVAC pulls 5,000 watts and still struggles. Less than half the storage, a comfortable win.
Then there is the case with no slack in it at all. Ziroth went through Panthalasa's patents to work out how its unanchored wave energy buoy generates power, and the numbers he found are sobering: a prototype rated at 50 kW that a screen in the company's own documentary showed producing 2.5 kW, at a conversion efficiency of around 44 percent, with the water falling roughly 10 metres instead of the hundreds a normal pumped hydro scheme gets. 2.5 kW is about twice what Adam's entire air-conditioned house was drawing. There is no bigger battery to specify here. Efficiency is not a lever on the machine, it is the machine.
What to watch on the A2 is whether the drag work turns into a measured result. A coefficient is a claim made in a wind tunnel. Watt hours per mile at 70 on a motorway is what an owner actually pays, and none of these three reviews carries a measured figure, because none of them included a range test. Autogefühl puts the premium over a comparable ID.3 at around €4,000. If the aero package cannot show a real difference against its own sibling on a real road, that money is buying a shape and a badge, which is a legitimate thing to buy, but not what Audi is selling.
The A2 Comes Back on a Seven-Year-Old Platform
Autogefühl's Thomas walked a production A2 e-tron in intense blue with the S line package, and he does not spend long getting to what is underneath it. He says the car uses the MEB platform shared with the VW ID.3 and Cupra Born, and that Audi's separation from those siblings comes from the body and the fittings rather than the hardware. Gas struts on the bonnet instead of a prop rod. A small frunk the siblings do not get. Touchable Audi rings front and rear, back after several years of flat badges. Length is 4.32 metres, wheels run from 18 to 20 inches, and he says the 19-inch aero wheel with the lowered sport or DCC adaptive suspension is the combination you need for the best range figure.
Batteries, as he lists them: 50 kWh LFP, 58 kWh LFP and a 79 kWh NMC pack, 11 kW on AC, and a 183 kW DC peak on the large one taking 10 to 80 percent in 29 minutes. His sharpest point is that the 50 and 58 are the same physical battery, with the smaller one restricted in software. He argues Audi should have sold that as an upgrade a buyer can unlock later rather than as a permanently smaller product, which is worth knowing before anyone orders the entry car to save money.
He gives pricing as €38,000 to start, €49,000 for the large battery and €51,000 with the quickest drivetrain, roughly €4,000 above a comparable ID.3.
Half a Metre Longer, and All of It Aimed at Drag
Electrifying got to see the car in a Munich studio but not drive it, having already sent a colleague to drive a camouflaged prototype she was not allowed to look at. The presenter puts the size change plainly: the original A2 was 3.83 metres long, the new one is 4.32, plus 12 centimetres of width, with the height about the same at 1.55 metres. That moves it into the Kia EV3, ID.3 Neo and Skoda Elroq bracket rather than anything genuinely small, and she says she would rather Audi had been brave and built something Renault 5 sized.
What Audi did instead gets catalogued in unusual detail. Air curtains around the arches, what the video calls a first for Audi in the gap breather behind the front wheels, an active shutter that only admits cooling air when the car needs it, a front splitter, an almost fully covered underbody with the rear suspension shrouded, and a diffuser spanning nearly the whole rear with a sharp separation edge. All of it for 0.24, which the same video is quick to measure against the Skoda Enyaq coupe at 0.22.
Quoted figures: 262 miles from the entry pack, 320 from the middle, 397 WLTP from the 79 kWh, 170 to 326 horsepower, 8.8 to 5.5 seconds, rear-wheel drive throughout, and prices from just over £32,000. Boot space is 396 litres. The frunk is 13 litres and will not take the cables.
Doors With Their Own Batteries, and a Frunk That Beats the Cables
carwow's walkaround is the one hunting for what an owner will still notice in year three. On the credit side: the door handles sense a press rather than clicking, and the host says each door carries its own battery so it will open even with a flat main pack. There is a real household socket in the boot, three-pin in the UK or two-pin in Europe, rated at 16 amps for vehicle to load. Wireless charging is quoted around 25 watts with USB-C ports above 60, enough for a laptop. There is an ISOFIX anchor on the front passenger seat, three-way folding rear seats, and an electrically deployable tow hitch rated at 1.6 tonnes, which the host compares to a Tesla Model Y. He also says the A2 is replacing the Q2 and the A1, with a wheelbase almost 20 centimetres longer than the Q2's, and rear knee room that surprised him.
The debit side: heavy bezels around both displays, one capacitive panel handling most steering wheel functions, a start button he calls ergonomically bad, scratchy plastics lower down, and a sensor pod that eats into the middle of the windscreen. The frunk defeated the charging cables entirely.
carwow lists the packs as 52, 61 and 84 kWh and prices from about £32,000 to £45,000. Those capacities sit above the ones the other two channels give, a gap that normally comes down to whether gross or usable capacity is being quoted.
The Wave Buoy That Pumps Its Own Reservoir
Ziroth read through Panthalasa's patents and technical documents to work out how the company's wave energy system actually generates power, because very little of it is explained publicly. The answer he describes is a pumped hydro plant that fills itself. A long narrow tube hangs beneath a floating node, open at the bottom. As the node rides a wave and drops away, the water inside cannot reverse direction as fast as the structure does, so it gets rammed through a narrowing and up into a reservoir above the waterline. That water then falls through a turbine. He demonstrates the principle outdoors with a water bottle, which works better than he expects. There is no anchor and no cable to shore, and the current plan is to run computing hardware on board and relay results by satellite, using the ocean as both power source and heat sink.
The numbers are where he gets careful. The Ocean 2 prototype is reported at a 50 kW maximum rating, but a data screen in the company's own documentary showed 2.5 kW, at a conversion efficiency of around 44 percent. He points out the water only drops about 10 metres, against the hundreds or thousands available to conventional pumped hydro. Commercial units are targeted at 200 kW to 1 MW. The February 2024 test ran three weeks, which he says tells you nothing yet about durability, corrosion or marine growth.
The Smaller Battery Won the Off-Grid Test
Ricky from Two Bit da Vinci and his friend Adam cut both their San Diego houses off the grid for 48 hours during the hottest week of the year, both running Anker SOLIX E10 systems. Anker supplied two extra batteries for the test, taking Adam's stack to 30 kilowatt hours against Ricky's 68. Adam never dropped below roughly 40 percent and made no real sacrifices, air conditioning included. Ricky fell to 16 percent on the first night and spent the second day, which turned cloudy and then rainy, switching off the AC, slowing the pool pump and cancelling all car charging.
His own diagnosis is that the building decided it, not the storage. Adam has a modern inverter heat pump and good insulation, and his house sat around 1.2 kW; Ricky says his HVAC draws 5,000 watts and still does not cool properly, and his office pulls a constant 2.2 kW, about 48 kilowatt hours a day on its own.
Two side findings are worth having. Ricky says most grid-tied solar inverters shut down when they detect no grid, as a safety certification requirement, and that this system keeps the panels working by forming its own grid signal. And the event log turned up a genuine two-hour utility outage overnight that Adam had slept straight through without noticing.
Bottom line: If you are shopping the A2, the number that matters has not been published. A drag coefficient is a design claim; watt hours per mile on a real motorway is the result, and until someone measures one, paying roughly €4,000 over an ID.3 buys you styling, a slightly better interior and a 13 litre frunk. That may be enough for you. The off-grid test is the clearer and cheaper lesson: insulation and a decent heat pump beat 38 extra kilowatt hours of battery, cost less, and keep paying back every ordinary day the grid is up.
