If still go is main alongside your priorities for an ecofriendly vehicle, the Audi A8 hybrid is non for you. There isn’t much inwards the means of quiet, electric-only operation, which makes sense, of course, given that this isn’t a fully electrical car. (You tin run exclusively on electrons for almost 2 miles at a constant 37 mph, together with if you lot awaken the engine, EV means volition reengage automatically when you lot relax on the accelerator. Top speed inwards all-electric means is 62 mph.) And although you lot mightiness never detect its internal-combustion pump beating if you lot dawdle at or below the measurement of traffic, the engine brings attending to itself with a subdued but noticeable growl in 1 lawsuit you lot telephone phone for whatever existent power.
The sucking, squeezing, banging, together with blowing noises come upwards from the VW Group’s ubiquitous 211-hp, 2.0-liter four-cylinder, teamed hither with a 54-hp electrical motor that’s integrated with a ZF eight-speed automatic transmission. Electrical storage capacity is provided yesteryear a 1.3-kWh lithium-ion battery pack. Power is sent only to the front end wheels. Combined together with at amount steam, the powertrain delivers 245 hp together with 354 lb-ft of torque. This arrangement is almost identical to the 1 offered inwards the A6 together with Q5 hybrids.
We Suppose That’ll Do
We justice the A8 hybrid tin attain lx mph inwards almost 7.2 seconds; Audi claims a drag-limited top speed of 146 mph. It is non governed, together with nosotros institute you lot tin easily attain 155 or to a greater extent than mph on downhill sections of the High German roads on which nosotros drove. This sort of performance should last sufficient for most markets together with customers. But it does non compare to the relentless ability you lot experience when you lot measurement on the throttle of the 2011–12 BMW ActiveHybrid vii (since neutered for 2013) or Lexus LS600hL. Nevertheless, piloting this A8 tin last satisfying for hybrid lovers who receive without urgency. At that point, this A8’s hybrid arrangement goes almost its line of piece of job concern unobtrusively. Up to 99 mph, you lot tin practise what VW Group brands similar to telephone phone “sailing,” that is, if you lot receive got your human foot off the gas, the electrical motor doesn’t aggressively recapture energy, allowing for a smoother coasting experience. You’ll last all smiles at the gas station. At 37 mpg inwards the European combined cycle, the A8 hybrid is the most efficient gasoline-powered luxury sedan. For comparison, on the same exam cycle, the Mercedes-Benz S400 hybrid gets thirty mpg, the LS600hL returns 25 mpg, together with the 2011–12 ActiveHybrid vii achieved 25 mpg. (We justice ratings for the A8 hybrid on the somewhat to a greater extent than realistic EPA bicycle at 24 mpg metropolis together with 34 highway.) During spirited driving, you lot tin experience the electrical motor lending a hand, a welcome boost during quick passing maneuvers every bit long every bit the batteries aren’t depleted, which happens all besides quickly. As for when the route begins to bend, it isn’t much fun to exam the A8 hybrid’s limits. We honey piloting whatever A8—and nosotros include the sporty S8 here—and it’s our reigning champion inwards the segment, but this is the to the lowest degree dynamic of the bunch. Even with 290-ish pounds of hybrid gear, at an estimated 4150 pounds, the motorcar isn’t really heavy versus its competition. But with ability routed only to the front end wheels, this hybrid relentlessly together with gracelessly pushes through corners; nosotros wished for Quattro. There is only 1 other front-drive A8 variant: the Europe-only 204-hp, 3.0-liter V-6 diesel fuel version, which incidentally gets fifty-fifty amend combined mileage than the hybrid at 39 mpg on the European Union cycle. The brakes are relatively numb, but the transition from electrical recuperation to hydraulic braking is good camouflaged.
Other A8s Make More Sense
Otherwise, the A8 hybrid is an exceedingly comfortable long-distance cruiser, together with its four-cylinder-based powertrain is sufficient if performance together with bragging are non your main objectives. But how much feel does the hybridization make? Its drawbacks include extra weight together with complexity, the gas tank shrinks from 23.8 to 19.8 gallons, together with body infinite is downwards from xviii cubic feet to a far-less-usable 11.8.
