2015 Jaguar XE 2.0d 180 Portfolio UK review

Beautiful poise and supple handling earns this smallest Jag a class-leading recommendation. It's not perfect, mind, but it's very good.

What is it?: 

One of two all-important four-cylinder diesel versions of the newJaguar XE. You’ll have seen the cringe-worthy, overcooked TV advertising campaign and you may even have seen one on the road - or perhaps on the back of a vehicle transporter. But will you be driving one?
The numbers in the brochure give the XE every chance. With the entry-level diesel version priced at under £30,000, emitting less than 100g/km of CO2 and getting an 8.0in touchscreen multimedia system, sat-nav, DAB radio and cruise control as standard, it’s got the makings of a popular fleet saloon.
But it’s the higher-output 2.0-litre ‘Ingenium’ turbodiesel that’s under scrutiny here, and it has some equally competitive power, torque, performance, economy and emissions figures. We’re testing the eight-speed automatic version, in higher-end Portfolio trim.

What's it like?: 

Many of the same observations we made of the 2.0-litre turbocharged petrol XE road-tested earlier this month also apply to the oil-burner. It’s a handsome design and recognisably a Jaguar, but it’s not as stylish or daring as its bigger four-door siblings.
Gaydon has played it a bit safe with this car, and understandably so given that it has ambitious volume targets for it. The sharply drawn front-end and fuselage profile are stand-out visual features, although the car is less distinctive from the rear, where it borrows more styling cues from the German opposition.
Inside the cabin, the XE adopts a similar position to those of the XF and XJ relative to their market rivals. It’s not quite as plush or as accommodating as some at the price, but it makes a virtue out of its simplicity and compactness.
Occupant space for the driver is adequate, but snug rather than generous. A slightly high-mounted seat combines with a typically graceful swooping Jaguar roofline to limit headroom for taller drivers. The closeness of the extremities of the footwell, meanwhile, and the raised centre console, support your knees and elbows rather than restrict your movement.
Second-row cabin space is broadly competitive although short of the standard of the most practical compact executive saloons, so full-sized adults may struggle a wee bit for knee and head room. The boot is a fair size but the Audi A4 and BMW 3 Series offer a little more cargo space.
Jaguar isn’t known for outstanding material cabin quality and won’t be changing its reputation by out-dazzling the likes of Audi and Mercedes with the XE. The car’s interior is nonetheless very pleasant, fairly luxurious and consistently well-finished.
The black plastics and leathers of our test car were a bit plain, but lighter and more visually appealing two-tone upholsteries are offered. The car’s switchgear is all either grained or rubberised, and its instruments are pleasingly conventional and clear.
For a brand new engine, Jaguar’s ‘Ingenium’ 2.0-litre turbodiesel doesn’t make the greatest of first impressions. Starting with some notable shake and shudder, its audible signature is a little more coarse than the most refined four-cylinders, and it remains so under load and at high revs.
It offers strong low and mid-range pulling power, though, and while you’d bet that its outright performance isn’t quite segment-leading, it’s well metered out by ZF’s excellent eight-speed automatic ’box.
The transmission’s natural bias is to upshift early and keep the engine spinning at fairly low revs, where it’s at its quietest and most economical. Throttle response at those crankspeeds is good, however, and power delivery is pleasingly muscular and elastic.
Cycle through Dynamic, S and manual paddleshift modes and you can make the gearbox hold a ratio for as long as you like, but the reward for doing so isn’t as compelling as it might be. While the engine revs more freely than some, it doesn’t do so all that willingly beyond 4000rpm.
Better, really, to settle for a more typical, torque-propelled turbodiesel driving style. The XE 2.0d 180 can certainly be spirited along quite quickly that way, and has grip and handling composure to spare on the road.
The car’s most laudable qualities are its fluent, consistent and uncorrupted steering, its balance and precision when cornering and its expertly judged blend of body control compromised against a supple and quiet ride. On all of those fronts, it’s king of the compact executive class.
Our test car had standard passive suspension, although firmer sports springs and adaptive dampers are available as an option. But the XE needs neither to feel athletic and involving, and to conjure an effortless and instant sense of poise that a BMW 3-series will only approach in perfect specification and dynamic setting.
The XE’s steering is quite quick just off-centre but is predictable and feelsome thereafter. Moreover, the suspension doesn’t seem to need to resort to overly firm springing or uncompromising anti-roll control in order to maintain good grip, body control or directional response.
Ultimately it handles cross-country roads with a dexterity unknown to most small saloons, and manages to feel at once stable, compliant and well-damped at motorway speeds.

Should I buy one?: 

Do you care more about the dynamic performance of your business saloon than anything else? Since you’re reading this, we’ll assume that you do, and if you do, the XE makes a strong case for itself. Narrowly – and perhaps only for the likes of us – a winning one.
The XE doesn’t dominate its rivals like the current BMW 3 Series did at launch, leaving at least a bit to be desired on practicality, material quality and mechanical refinement. But it’s a competitive prospect even where’s it's relatively weak: something you’d never have said of the old X-type.
Moreover, Jaguar has evidently concentrated its budget and effort where it knows it can create a real selling point for the XE: on driver appeal. And, as ever, we’re a sucker for it.

Hyundai Tucson PHEV Debuts In Geneva

hyundai-tucson-phev
It wasn’t that long ago that the Hyundai Tucson Fuel Cell vehicle debuted in Detroit with some fanfare, and the promise of free fuel. It seems that the Korean automaker is hedging its bets when it comes to hydrogen though, debuting the Hyundai Tucson 48V Hybrid Concept and an even more-efficient plug-in hybrid diesel, both riding on an all-new platform.
The Tucson 48V Hybrid Concept pairs a 2.0 liter turbodiesel engine making 134 horsepower with a 14 horsepower electric motor powered by a 48-volt lithium-ion battery pack. Total combined output of 148 ponies and 305 lb-ft of torque through a six-speed manual transmission, and the Hyundai contributes just 109 g/km CO2 to the atmosphere. Though just in hybrid form, Hyundai wants to bring this technology to its larger SUVs as a means to offset emissions at just a quarter of the price of full hybrid system might cost.
But the automaker didn’t stop there, as the Tucson PHEV concept not only offers more power, but a respectable electric driving range as well. A 1.7 liter turbodiesel making 113 horsepower is mated to a 67 horsepower electric motor for combined output of 180 horsepower and a substantial 350 lb-ft of torque. Electric driving range is estimated at 31 miles per charge of the 10.7 kWh lithium-ion battery, and CO2 emissions are estimated to a mere 48 g/km, less than half the 48V Concept. The electric motor can drive the rear axle, while the diesel engine powers the front wheels, offering a hybrid drivetrain not unlike the Kia Soul e-AWD concept that debuted earlier in the month. There’s also rumors of a dedicated EV coming as early as next year.
The new Hyundai Tucson comes with a host of other improvements, such as new engine, connectivity, and safety features. But the big news to me is that Hyundai is debuting an all-new Tucson, sans the hydrogen drivetrain they made such a big deal about less than a year ago. At the Detroit Auto Show, Hyundai showed off its first Sonata Plug-in Hybrid, but it barely mentioned its efforts with hydrogen. This could be another indication that the automaker may be moving away from hydrogen fuel cells or, at the very least, making sure it doen’t ignore a growing plug-in car market.

Volkswagen Reveals New 268 Horsepower TDI Engine

volkswagen-2.0-tdi
The Volkswagen TDI line of turbodiesel engines has been a cornerstone of Wolfburg’s new car lineup for over three decades, and with each evolution it only gets better. Volkswagen has revealed a new 268 horsepower version of its 2.0 liter TDI engine, using an electric turbocharger to make it the most powerful TDI yet.
Electric turbochargers are going to play a huge role in Volkswagen’s lineup, with the Audi Q7 to debut the technology in a production model in the next couple of years. Despite having two fewer cylinders and a whole liter less of displacement, the new 2.0 liter TDI actually makes 10 more horsepower than the just-updated 3.0 liter V6 TDI, and about 30 horsepower more than the outgoing 2.0 liter TDI motor. It is however overshadowed by a more potent version of the 3.0 liter V6 found in the RS5 concept, churning out a healthy 326 horsepower.
Despite this though, the new motor is actually 14% more efficient, which could mean an extra 4 or 5 MPG on the road. Volkswagen isn’t talking torque numbers just yet, but it should be in the same area as the outgoing model, which offered 369 lb-ft of twist.
So where can we expect to find this uber-powerful TDI motor? The engine is going to be reserved for upper-end models, including the upcoming production version of the Volkswagen CrossBlue SUV concept. VW also released a few details on its upcoming 10-speed dual-shift gearbox (DSG), including a torque limit of 405 lb-ft and a coasting function that shuts down the engine similar to a start-stop system, but while the car is in motion at speeds under 4 MPH.
Volkswagen is also investing heavily into plug-in vehicles, which leaves the door open for a hybridized version of this drivetrain, perhaps pairing it with a couple of electric motors for even better performance. A guy can dream, right?

2013 Volkswagen Golf - REVIEW




The 2013 Volkswagen Golf is the latest model in a run of distinctive German compact hatchbacks that has lasted more than 35 years. From the very first Rabbit introduced in the mid-1970s through several generations of Golf (and a transitory, mistaken return to the Rabbit name from 2006 through 2009), the Golf has always stood for sensible, solid, well-handling hatchbacks. The bulk of Golfs sold these days are the five-door model, though VW also offers a rare three-door hatchback that finds few buyers outside the sporty GTI and high-performance Golf R variants.
The Golf competes with compact hatchbacks like the Ford Focus, Subaru Impreza, and the Mazda Mazda3, plus the newer Hyundai Elantra GT and the Kia Forte. And the segment that's growing again, as the industry mantra that "buyers don't want hatchbacks" slowly fades. The Golf's Jetta four-door sedan sibling is still more popular, but the Golf has its place and VW is one of the few makers that's sold hatchbacks continuously in this segment.
The Golf's selling point is that it feels like more of a premium car than most of those competitors. The downside is that its European pedigree, more sophisticated technology, and high-quality interior make it one of the priciest compacts sold by a mass-market brand. The Jetta and Passat are Volkswagen's volume cars, and the Golf remains more of a niche player.
You can get a Golf with several different powertrains. The base model starts below $19,000, but while it feels perky behind the wheel, its 170-hp five-cylinder engine is neither fuel efficient nor refined. It comes with either a 5-speed manual gearbox or a six-speed automatic transmission, both rated at 26 mpg combined. The sporty GTI model is a blast to drive, powered by a smooth, flexible turbocharged 2.0-liter TSI four-cylinder engine that's rated at 27 mpg with a six-speed DSG direct-shift automatic, or 25 mpg with a six-speed manual gearbox.
The even higher-performance Golf R version, sold only with the six-speed manual, adds a version of the 2.0-liter turbo engine that produces 256 hp , powering all four wheels with a version of VW's 4Motion all-wheel drive system, a performance Haldex clutch pack, and many other improvements including stronger brakes, a lower, stiffer suspension, and dual exhaust outlets. Its gas mileage is rated even lower, at 22 mpg.
For fans of fuel efficiency, by far the most appealing Golf will be the TDI diesel model. The torquey, long-lived 2.0-liter four-cylinder turbodiesel engine not only delivers a combined EPA rating of 34 mpg, its owners report that the car often exceeds those numbers in real-world usage. The highway cycle rating of 42 mpg points to the diesel's true strength: its extreme efficiency running at sustained speeds. In city usage, the 30 mpg rating is less impressive. The diesel can also be ordered with a six-speed DSG dual-clutch transmission, considerably retuned to match the diesel's narrow power output band, and that combination is rewarding to drive at the same time it delivers great fuel economy. But be warned that low fuel costs don't come cheap: The Golf TDI starts more than $6,000 higher than the base gasoline version.
Behind the wheel, the 2013 Golf offers a firm but quiet and comfortable ride, with responsive electric power steering that delivers enough road feel to hide its digital origins. The TDI diesel models have slightly sportier suspension settings, and brakes are a strong point on all Golf models. Front seats are comfortable and supportive, though the Golf lacks back-seat space compared to newer compact hatchbacks--and getting into and out of the back in the three-door models is an exercise in contortion. The cabin provides a pervasive feeling of quality and refinement, with no-nonsense instruments and controls and thankfully little electronic distraction.
Compared to more value-oriented Asian imports, the Golf may not deliver quite the equipment-per-dollar level of a Kia or a Hyundai. But its features and options distance it from the "economy car" end of the compact spectrum, with TDI versions including a touchscreen display for the stereo system, satellite radio,Bluetooth, and audio controls on the steering wheel. The GTI adds more features yet, including 18-inch 'Detroit' alloy wheels, heated side mirrors, a sport steering wheel, and various exterior and interior appearance upgrades. A touch-screen navigation system and a sunroof are optional, but it comes up slightly short on the kinds of active safety systems that are now appearing rapidly even in the compact car class--specifically in newer models like the Ford Focus, which is perhaps the closest of all competitors in character and equipment to the Golf. Finally, the Golf also lacks Bluetooth connectivity in base mdoels, a notable omission.
