Let’s be honest. The compact luxury sedan is an irrational car. It’s the size of a Honda Civic but costs twice as much. People are willing to pay a substantial premium for the experience of owning, driving, and of course being seen in one of these premium cars.
So think of this not as a Big Test but instead as a Big Picture Test, where the judges turn into bit actors, spending even more time than usual in the mindset of actual shoppers looking at this class of vehicle.
Like any in-market consumer, we looked at the whole picture, including price, depreciation, reliability, dealer experience, safety, infotainment features, and cargo- and passenger-carrying capacity. But given the nature of this category, subjective criteria also come into play, so things such as styling, brand image, overall appeal, and driving enjoyment are major factors in this test.
Our entry criteria were simple: a zero-down-payment, $399/month lease, four doors, and a turbocharged 2.0-liter four-cylinder engine. The contenders: the Alfa Romeo Giulia, Audi A4 2.0T Quattro, BMW 330i, Cadillac ATS 2.0T, Infiniti Q50 2.0T, Jaguar XE 25t, Lexus IS 200t F Sport, Mercedes-Benz C300, and Volvo S60 T6 R-Design.
Because automakers tend to selectively apply incentives such as cap-cost reductions and padded lease-end residual values, we backstopped our lease deals with a target sticker price between $45,000 and $48,000.
Most automakers were able to supply us with an applicable vehicle, but Volvo instead sent a pricey turbocharged and supercharged T6 R-Design and not the T5 Inscription Platinum we requested—and was penalized appropriately. Infiniti had no 2.0-liter Q50 in its fleet, so we rented one from Hertz.
The ranking you see is the order in which we would buy or lease these cars with our own money. We spent weeks piling on thousands of miles of abuse on these cars to truly test their real-world abilities. Happily, our group of nine judges reached a consensus on the finishing order. Feel free to argue about how your personal driving preferences bias you toward one car over another. But remember: If this were all about buying the most practical choice, you’d just buy a Civic, right? -Jason Cammisa
Ride & Handling
The single most important attribute of a luxury sport sedan is the driving experience. It must handle like a four-door sports car, but it must also ride acceptably well for a luxury car. Nailing that balance is no easy task, and many came up short.
The biggest disappointment came from the BMW, which created the benchmark for this segment three decades ago. We’ve long criticized the latest 3 Series for being too soft, and this latest update hasn’t addressed that. The ride is comfortable, yes, but at the expense of handling, which no longer feels as sharp or focused. Rather than the class leader, it’s class generic.
On the other end of the spectrum is the Alfa. It was the nearly unanimous driver’s favorite, simultaneously a marvelous car to drive fast and still a comfortable commuter. The steering is quick, responsive, and talkative. The chassis responds perfectly to every input while muting every bump. More than any car here, it put the sport in sport sedan without suffering a jarring ride as a trade-off. A close second to the Alfa is the Cadillac, which got the vote from the lone dissenter. But its equally phenomenal chassis and steering were offset by a less luxurious ride quality.
Similar ride and handling trade-offs were the rule among the Lexus, Jaguar, Mercedes, and Audi. The Lexus handles nicely and rides well, but its portly curb weight made it feel heavy and dulled its responses. The Jaguar and Mercedes handled very well, but rubber-band tires and stiff shocks hurt their ride quality. The Audi both handled and rode very well, but the experience was very isolated and disconnected from the road. Many an editor likened it to a driving simulator.
The Volvo, which once overachieved in this category, felt a generation behind. The heaviest car here, its weight was a constant presence in corners despite the all-wheel drive’s best efforts to yank it out of the corner and down the straight. The steering was full of vibration from the all-wheel drive, and the ride wasn’t spectacular. In a hot segment, it’s just out-classed.
The Infiniti was by far the most difficult to judge. Our rental exhibited a strange cornering behavior. The front turned first, then the rear end seemed to leap over onto the outside tire a heartbeat later, making it feel as though the car was going to suddenly oversteer, which it did not. Concerned, we took it to a dealer to confirm nothing was broken, and it was given a clean bill of health. We suspect an alignment problem. Regardless, the Q50’s steering was universally deplored for its heavy, artificial weighting and total lack of feedback. Ride quality was, at best, average.
Performance
Given the range of vehicles you could lease at this price, your decision to go with a sport sedan suggests you value performance. As such, this attribute likely weighs heavily on your purchase priorities. It’s the bedrock attribute of this segment.
The BMW 3 Series defined this segment and ruled it for decades, but in this test, it comes up average. It’s slightly above midpack in acceleration but among the worst in braking and just average in our instrumented handling tests. Still, judges praised its linear acceleration, minimal turbo lag, and excellent transmission programing.
If you want absolute performance at this price point and fuel economy, look no further than the Audi. A sleeper, the conservatively styled A4 is the quickest both in a straight line and around our figure-eight test. Its dual-clutch transmission and all-wheel drive give it a performance and traction edge off the line. But beyond 60 mph the Alfa’s best weight-to-power ratio and shortest gearing deliver the best performance, reaching 100 mph 1 second quicker and finishing the quarter-mile 3.3 mph faster than the Audi. Likewise, the Mercedes, with its Sport package, equals the Audi’s best-in-class figure-eight performance while stopping shorter. The Alfa’s figure-eight performance was severely handicapped by its overly aggressive stability control, which couldn’t be defeated.
The Cadillac comes up surprisingly short given its second-most powerful engine and second-lightest curb weight. We attribute this to its tallish first gear and somewhat lazy transmission. The Jaguar’s second-shortest gearing compensates for its second-worst weight-to-power ratio to produce solidly midpack performance.
The Lexus earned its slowest straight-line performance fair and square with the second-highest curb weight (despite being only rear-wheel drive) and the second-least powerful engine. It just felt overburdened. What the Lexus lacked in power, though, it made up for in handling.
Then there’s the odd case of the Volvo. A turbocharged and supercharged T6 variant rather than the directly comparable turbocharged T5 we requested, it was the most powerful in the test and blessed with all-wheel drive and the R-Design sport package, not to mention a Polestar engine software upgrade. It was also, however, the heaviest. As such, it was third-quickest to 60 mph and stopped second-shortest, but it was slowest on the figure eight by a good margin.
There’s also the matter of the Infiniti, which finished in the bottom half as equipped but might have performed differently had it been equipped like the others. Moreover, Infiniti is offering a $399 lease deal on Q50s with the 3.0-liter twin-turbo V-6, which performs substantially better (though at the obvious cost to fuel efficiency).
Efficiency
Gas is pretty dang cheap right now, but it won’t always be. Even when it’s cheap, it’s still an expense. There’s also an expectation of good fuel economy that comes with a downsized engine. After all, you want some payback when you give up horsepower and torque.
According to the EPA’s standardized lab test, these vehicles all return very similar fuel economy. Going by window stickers alone, we see most get around 23/32/26 mpg city/highway/combined. The Jaguar fares the worst, posting 21/30/24 mpg rating. The Mercedes just beats out the Alfa and the Audi by returning a best-in-test 24/34/28 mpg city/highway/combined. As you can see, it’s not a broad spread.
Here, our Real MPG partnership with Emissions Analytics is invaluable. In real-world testing, the Mercedes fell 2 mpg short across the board, abdicating its top spot. The Jaguar redeemed itself in city and combined ratings, and the Lexus dropped to a worst-observed 20.4/31.1/24.2 mpg city/highway/combined. Meanwhile, the Alfa soared with an observed 28.2/37.9/31.8 mpg city/highway/combined, well above its EPA estimates in all categories. We must caution, however, that our Alfa Romeo and Lexus were preproduction units, and both could show different results once their final software calibrations are made.
Cockpit/Cabin
Much of what makes a luxury sedan is its interior. After all, it’s the place where you spend time and the part of the car you spend the most time looking at, touching, listening to, and interacting with.
Regardless of the metrics used to score such subjective criteria, the Mercedes comes out on top. The elegant design and top-quality tactile materials made it a unanimous favorite among the judges. It also scored high marks in quietness, comfort, and rear-seat space. It was let down slightly by a cut-rate Garmin navigation system integrated into the otherwise all-Mercedes infotainment system.
The Audi also was well-received by the judges. The technical superiority was obvious; its virtual cockpit digital dash looked like something out of the future and offered features and functionality no competitor could match. We were also impressed with its impeccable build quality and excellent materials. It took demerits for a slightly tight rear seat, somewhat sterile design (apart from the dash), and slightly louder interior than we’d prefer.
Lexus came in a strong third, with high marks for build quality, materials, and interior quietness. Its design was controversial, and the rear seat was a bit cramped, but the seats were lauded for their comfort and support. The infotainment system and its finicky joystick interface earned unanimous scorn, even from the most generous judge. Even dismissing the controller, the system itself looks old and outdated, and it isn’t especially intuitive.
Other cars let down by their infotainment systems were the Cadillac and Jaguar. Although Cadillac’s CUE system is the best iteration to date, many of the judges still found the touch-sensitive controls difficult to use while driving and not always responsive. The Jaguar, also sporting its best infotainment system in years, drew complaints for being unintuitive and for crashing on several editors. Both cars were also hammered for their nearly unusable rear seats and rather dull interior designs.
The Volvo and BMW, meanwhile, were complimented for their comfort and decently sized rear seats but criticized for their dated interior designs and average materials quality. The BMW clawed some points back with its ergonomics, and the Volvo did, as well, because of its excellent seats. The BMW took hits for its incomprehensible Apple CarPlay integration, and the Volvo was dinged for its loud interior, especially for admitting rough engine noise into the cabin.
Then there’s the Alfa. Praised for its interesting and stylish interior design, it took knocks for its wonky ergonomics. We liked its decently large rear seat and comfortable front seats, but we took issue with the fit and finish and some cheaper materials.
Alas, Infiniti. Every judge praised its massive rear seat and the comfort of its Zero Gravity front seats, but that was about it. Many remarked the car didn’t have a premium feel to it, something akin to a top-shelf Nissan rather than a purpose-built luxury car, which no other competitor suffered. It was also dinged for an unintuitive double-screen infotainment system, which featured two screens with different graphics, fonts, colors, and more. The interior was also loud with vibrations from the powertrain and road creeping in.
Safety
As it was with fuel efficiency, our competitors are evenly matched in both government and insurance industry crash tests. No competitor scored lower than four stars out of five in the National Highway Transportation Safety Administration’s testing or Good in an Insurance Institute for Highway Safety crash test. (IIHS scores range from Poor to Good in crashworthiness testing and from Basic to Superior in crash-prevention systems.) Still, there are details to be examined here.
We should note before going forward that neither the Alfa Romeo nor Jaguar have yet been tested by either U.S. agency. The cars have been crash tested by their manufacturers and the results accepted by the NHTSA, so they can be sold in the U.S. Both cars also received five out of five stars in Europe’s Euro NCAP crash testing. We should also note that some data used here comes from the 2015 and 2016 model years, but the vehicles in question have not changed substantially between then and the current model year.
As you might expect, the Volvo came out on top of a very competitive field. The company, which stakes its reputation squarely on safety, had perfect scores in every crash test and top marks in the IIHS’ tests for seats and crash avoidance systems, as well as high marks in IIHS tests for headlights and LATCH child seat anchors. It is an IIHS Top Safety Pick+, along with the Audi and BMW.
Among the rest of the pack, only the Volvo and Cadillac achieved a five-star front crash rating from NHTSA. The rest received four stars. All but the Mercedes-Benz received a five-star rollover rating from the NHTSA—the C300 scored four stars. Every competitor received five stars overall from NHTSA.
The IIHS hasn’t completed all tests on every competitor. In crash-prevention testing, the BMW and Lexus were the only two tested cars to receive an Advanced rating on their crash-avoidance systems. The rest received Superior grades. The Cadillac and Mercedes received Poor ratings for their headlights, and the rest tested received an Acceptable rating.
Value
Because you’ll be paying the same lease price on all these competitors, value requires a different measurement. After all, no one wants to pay the same for a lesser car. How you define value is up to you, but for the purpose of this comparison, we’ve framed it as the content and performance you get for your $399 monthly payment. (And because many people buy out their leases, sticker price and retained value matter even in a leasing context.)
On this metric, the Audi shines brightest. Although its purchase price is on the higher end of the group, the return on investment is high. The Audi boasts the highest performance in our instrumented testing while also offering far more features than the rest. With price equalized, there’s no questioning the Audi’s dominance in the amount of car you get for the money. The Alfa scores high on performance and boasts the cheapest purchase price as-tested but has fewer features.
In the middle of the pack, the Jaguar offers quite a few features but is let down by low performance scores and a high as-tested price. The Lexus lands in a similar boat, but boasts a better as-tested price. The BMW, Cadillac, and Mercedes all offered a similar balance of performance and content. Cadillac, Mercedes, Lexus, and Volvo all sent cars equipped with sport handling packages, potentially in lieu of other content for the same money. BMW and Cadillac also tend to charge extra for features others include standard.
The Volvo stands out as a difficult case. Because a T6 R-Design was supplied, it carries the highest starting price and second-highest as-tested price, but it also snuck in a supercharged and turbocharged engine with by far the highest horsepower and torque output. As such, it performed well in testing and had high feature content. But at a $399 lease price, you’d actually get a T5 Inscription Platinum and give up the performance advantage.
The Infiniti is likewise difficult to judge in terms of value because our rental was a stripper. An appropriately priced Infiniti would’ve scored well on content, though likely even worse in performance with the added weight.
Cost of Ownership
Time is a luxury and therefore so is reliability; no one wants to spend extra time at the dealer.
Unfortunately, the information on the all-new Alfa Romeo Giulia is incomplete. Having returned to the U.S. market only recently, there simply is no empirical data regarding reliability, maintenance, repairs, and depreciation on an Alfa Romeo—although past models have taken slings and arrows in European quality ratings. We’ve calculated values for those categories based on information from multiple sources, and we took an average of costs for the rest of the competitors.
Per our partners at Intellichoice, the Cadillac is the car whose lease you might consider buying out. Although not the cheapest in any category, low costs across the board keep the Cadillac’s five-year cost of ownership to $45,592. Conversely, the Lexus suffers high insurance, fuel, and maintenance costs, giving it the highest five-year cost at $52,254.
There’s also the matter of complimentary scheduled maintenance. Sometimes it’s baked into the lease price, sometimes the manufacturer eats the cost as an incentive that changes from year to year based on the marketing department’s whim. At present, Jaguar offers five years/60,000 miles of free maintenance; BMW, Cadillac, and Volvo offer three/36,000, and Lexus gives the first two services in the first year for free. Alfa Romeo offers the first service free, while Audi, Infiniti, and Mercedes charge for all maintenance.
We would also point out that the difference between the most and least expensive car to own over five years is less than $7,000, illustrating again just how evenly matched the competitors are.
Conclusion
We considered every facet of these nine cars. We debated long and hard over how to weigh each category, given the values of buyers in this class. We wrestled with missing data and reputations, balanced the marketing and hype, and noted the differing expectations and priorities between leasing and buying.
However, in a class where passion, prestige, and performance often take precedence over cold hard facts and logic, we follow our hearts as much or more than our heads.
As a result, the back of the pack is populated exclusively by older models who have seen the segment pass them by. The Infiniti makes a strong case for itself in both interior space and value, especially because you can get a better V-6 engine for the same lease payment as the others’ turbo-fours. Otherwise, it left our editors feeling there’s little reason to consider it over the others.
Right ahead of it was the Volvo, which finished in second place the last time around. Similar to the BMW, the S60 is betrayed by its age. Far and away the oldest car in the test, it was outclassed at nearly every turn. Thoughtful updates have kept it on life support and out of last place, but a new engine is no substitute for the comprehensive updates needed to make the S60 truly competitive, and the all-new car can’t come soon enough.
The BMW 3 Series easily won our last Big Test in this class, but even with a recent refresh we found it lacking. It led no categories and inspired little love from the judges, except for its zingy engine. The pressure is on Bavaria to up the next edition’s game if it wants to improve on its seventh-place finish here.
The Cadillac and Jaguar fought fiercely for position in the middle of the pack, with the American just edging out the Brit. Both cars drove wonderfully, but both were kneecapped by penned-in rear seats. The deciding factor ended up being the Jag’s glitchy infotainment system.
An excellent all-around performer, the Mercedes-Benz C300 is by far the most luxurious car here while still offering serious performance credentials. If its options packages were more value-oriented and the Sport edition carried a more luxurious ride, it might’ve managed the silver instead of bronze. It’s a similar story for the fourth-place Lexus, which punched above its weight class on many fronts but couldn’t overcome a weak engine and infuriating infotainment system.
Finishing in an honorable second place is the Audi A4. On paper the Audi wins in terms of features and space, while matching the Alfa’s objective performance, but a sterile personality and a sense of isolation from the driving experience kept it out of first place.
