Volvo is back in the big luxury-car business with the S90 (sedan) and V90 (wagon), targeting the BMW 5 Series set with progressive safety, engineering, driveability, and design. Both are a massive leap forward from the V70 and S80 they replace.

WHAT IS IT? Volvo understands that to achieve real respectability against the luxury German marques, it must design and engineer a car worthy of taking on the tremendously capable BMW 5 Series and Mercedes-Benz E-Class. That’s what the S90/V90 are aiming to do, and with an intriguing Swedish twist.

WHY WE’RE TESTING IT As Sweden’s remaining mainstream carmaker, Volvo reckons it can carve a slice of the larger premium sedan/wagon cake with a distinctly Scandinavian take on styling, performance, efficiency, dynamics, and safety. What’s different from before is that the all-new S90/V90 also strive to meet, or exceed, the segment highpoints. So have the Swedes finally broken into the premium premier league?

MAIN RIVALS Audi A6, BMW 5 Series, Infiniti Q70, Lexus GS, Mercedes-Benz E-Class

PLUS: Design, steering, handling, ride (with optional air suspension), safety, comfort, refinement, packaging, individuality MINUS: Progress means prices have soared, some equipment omissions, minor ergonomic glitches, jerky T6 auto

THE WHEELS REVIEW RECENTLY, a car-company boss confirmed what many have long suspected: that respectability only arrives when “you get your 5 Series rival right”.

Sharing about 40 percent of parts with the latest XC90 launched last year, the S90 actually drove the initial development of the all-new SPA Scalable Platform Architecture when work commenced during the dying days of Ford control in 2008. “Sedan buyers are very fussy, so we had to get its proportions exactly right first,” according to the ‘Cluster 90’ senior director, Kent Falck.

Even Volvo admits that outside of Sweden nobody was exactly aching for S80 and V70 replacements, so the S/V90 couldn’t just be BMW clones, but something different and compelling. Benchmarked against “basically the Germans”, they embrace Volvo’s controversial 2.0-litre four-cylinder powertrain strategy, with a circa-300kW/640Nm petrol-electric plug-in hybrid arriving later in 2017.

Almost in defiance of its 1969cc capacity, the T6 AWD is certainly no slouch, leaping forward into action and maintaining a cracking pace as long as you don’t spare the accelerator pedal. Maximum power tops out at a fairly highly-strung 5700rpm, but you rarely hear the four-pot turbo shriek otherwise, since there’s a sizeable wad of torque and smartly spaced gear ratios to keep things humming along sweetly. Conversely, the auto’s occasional jerky downshift, propensity to not upshift in Dynamic, and lack of wheel paddles sully an otherwise slick mechanical ensemble.

Yet it is the brawny D5 AWD that really – and literally – blows expectations clean away, thanks to the patented PowerPulse tech. Using compressed air to multiply turbine speeds, it slashes turbo lag for a strong and stirring stream of performance stamina, and without the off-boost blues to impede progress.

As with the XC90, the ‘Drive Select’ offers overly light and softly suspended ‘Eco’ and ‘Comfort’, but in the pitch-perfect ‘Dynamic’ setting, the whole car gels terrifically. Thank the optional 20-inch rubber, lower centre of gravity, or reduced mass, because poise and response are the happy by-products. Turn-in is instant and linear, the handling receptive, and the chassis planted. Even the wagon shrinks around you blasting along a tight and twisting hairpin. Extra-cost rear air suspension also helps impart a supple and isolated ride, further boosting our admiration.

Neither model is actually sporty, but there is a newfound athleticism that keen drivers can work with. Volvo calls it “Relaxed Confidence”. Let’s hope such comfort and control translates on Aussie roads.

The Inscription series for both the D5 and T6, equals interior sumptuousness – meaning this S/V90’s hushed cabin is more than a match for most rivals. Similar, but better resolved than the XC90’s lush leather and walnut, brushed aluminium and chrome meld seamlessly with the tech-heavy (and initially intimidating until familiarisation sets in) multi-screen displays, gorgeous instruments, truly lavish seating – front and rear – and detailing exquisite enough to impress Audi. A big audio volume knob is such a luxury nowadays. The thing reeks of opulence. At nearly five metres long, the same number of six-footers will also fit, despite the sedan’s sloping roofline.

From $79,900, the S90 T5 Momentum includes adaptive cruise; lane keep assist; blind-spot monitoring; reverse camera; automatic parking; leather seating; four-zone climate control; keyless start; electric front seats with memory; an electric boot lid; and LED headlights with bending tech. The Inscription, meanwhile, from $96,900 in the D5 AWD ups the ante with more performance and grip, 19-inch alloys (up from the base 18s), Nappa leather, and ambient lighting. The T6 equivalent adds another $2K.

Expensive for a Ford-era Volvo perhaps, but the Geely-funded S/V90 twins might have just made it as blinding BMW 5 Series botherers. Maybe not top of the heap but certainly Vi-kings of the hill.
