blogentry-114362-0-72553000-1535426252_thumb.jpgThis is your first look at the 2019 BMW Z4 Roadster, unveiled to the public at the Pebble Beach show a year after we saw the concept at the same event.


Unlike the previous Z4, this one will only be available as a soft top, with no retracting hardtop version in the pipeline. It shares a platform with the forthcoming Toyota Supra coupe, so to retain both cars’ market share the two body styles will remain separate.


blogentry-114362-0-03726300-1535426279_thumb.jpgBut with that said, BMW is still promising a far more entertaining car for drivers than the previous version. Andreas Ederer, product manager, joined us to walk around the car: ‘We didn’t have to make any compromises. This is the difference compared to the predecessor, there were more compromises in terms of sportiness and in this case it’s totally different. It’s pure sportiness.’


blogentry-114362-0-29810800-1535426283_thumb.jpgThe new BMW Z4 appears startlingly close to the concept. The double-stacked LED headlights and new mesh grille design remain from the concept car, and there’s a radar for the rudimentary driver-assistance systems hidden behind a cowl on the left-hand side to keep it hidden from view. We’re told this is in keeping with BMW’s philosophy that the Z4 is a drivers’ car, so any assistance should be kept under the radar.


blogentry-114362-0-21998500-1535426287_thumb.jpgAt the rear, the L-shaped light clusters have a fluid shape to them, much like the i8 and yet also harking back to the Z8 and other BMW’s of yore. They’re less fussy than the original concept’s, though.


A darkened brake light sits under the rear ‘ducktail’ spoiler, while reversing lamps and foglamps sit just above the rear diffuser.


As on the previous Z4, the long bonnet is a clamshell that lifts to reveal an engine sat around two thirds of the way behind the front axle.


blogentry-114362-0-70560300-1535426290_thumb.jpgIts side profile features fewer lines than we’re used to from BMW, and more use of twisting surfaces to create shadow. The windowline of the car is high relative to the driving position, which has the effect of making the driver feel very low down towards the tarmac.


The wheels you can see here are 19-inch items, which will be standard on the M40i, shod in Michelin rubber and sat in front of M Performance brakes.


The roof folds open and closed in 10 seconds at speeds up to 31mph, but why fabric rather than a folding metal hard top?


blogentry-114362-0-50984000-1535426294_thumb.jpgAndreas Ederer explains: ‘it’s lighter, it lowers the centre of gravity and it enables us to have the full trunk volume whether the car is open or closed. The soft top technology in terms of acoustic comfort is even better than the retractable hardtop we had on our predecessor, so therefore there is no reason whatsoever to go for another hard top.


Said luggage volume is a useful 265 litres, up from 180 in the previous Z4 and apparently big enough for a pair of golf bags, should that sort of thing flick your switch.


Ederer also offered an insight into testing the roof for opening at speed: ‘One of the engineers, at a very early stage when it didn’t have protection, managed to open the thing at 180kph! Nothing was bent, but it was very close to being ripped off.’


Expect 0-100km/h in 4.6 seconds. It’s coupled with an eight-speed automatic gearbox including paddleshifters on the steering wheel, and there are Comfort, Sport and Sport+ modes to pick between – though these have more relevance to the handling, covered below, than the performance.

With 50:50 weight distribution thanks to the engine’s location (around two third of it is behind the front axle), MacPherson struts up front and a multilink rear end, the recipe is there for a half-decent sports car.


In addition, the M40i gets electrically controlled adaptive dampers and differential, with the latter similar in design to the M5’s and using identical software logic.


There may be a 20i and 30i versions, both using a 2.0-litre, four-cylinder ‘B48’ motor, and perhaps a manual gearbox for the 20i as was spotted testing. This last isn’t for performance, but rather to lower the base list price.

    BMW Alpina B5: Comfortable Cruiser

    Who says performance cars need to come with a sporty ride? Last week we tested the BMW Alpina B5 to see if Alpina's take on the performance saloon is a viable alternative to the BMW M5. So what sets this Alpina apart? Firstly, the interior has received a host of luxurious touches to set it apart from the regular 5 series: The digital dashboard in the B5 has its own Alpina-specific design and colour scheme, for example, while the handcrafted Alpina steering wheel is made of Lavalina leather (the same leather used in Rolls-Royce cars), and features blue/green stitching. But what truly sets this car apart from the rest of the performance saloon pack is what is underneath you: With a suspension designed to deliver comfort and refinement in spades, the Alpina is not just comfortable, but sublimely comfortable. Adding to the comfortable cruise is the fact that the B5 is joyously easy-going to drive, with the lightest of pressure on the accelerator sending the car wafting rapidly down the road. With the abundance of humps and rumble strips on our local roads, would Alpina's take on the performance saloon, with its effortless and classy character, be a better suit for your everyday commute? Read our full review here!



    Hyundai's green goal

    Hyundai is declaring its ambition to be a tree-hugging company. The Korean automaker announced that it will continue its efforts to be the most fuel-efficient automaker in America through the next two decades, with plans to achieve a Corporate Average Fuel Economy rating of 50 miles per gallon by 2025 for its entire vehicle lineup.   The cornerstone of Hyundai's approach is its Blue Drive strategy, which incorporates a range of engine technologies from turbocharging to direct-injection, lightweight materials and plug-in hybrids to reduce consumption and improve overall efficiency.   Hyundai points to the 2011 Sonata as the first wave of new products to utilize its new and improved drivetrains, available with either hybrid, turbocharged or naturally aspirated engines. The latest 1.6L GDI engine in the new Avante is also a shining example of Hyundai



    Ultimate 911 Turbo previewed: Porsche 911 GT2 RS

    Whenever Porsche comes out with a 911 that is designated a 'GT2' almost everyone gets nervous. The GT2 moniker is usually reserved for a high performance version of the 911 Turbo. It is lighter than the Turbo version as Porsche threw away the all wheel drive system and made it rear wheel drive. The 996 version of the GT2 became known as a 'widowmaker' as it channeled more than 500bhp from its rear mounted engine only to the rear tires. The recipe of the engine at the wrong place and too much power to the rear wheels made it even worse than the usual 911 type of scary, pendulum-like oversteering effect that happens when things go wrong. So what does Porsche do then?.   Porsche has now come up with an 'RS' version of the already manic GT2; the Porsche 911 GT2 RS. The car pictured above has supposedly lapped the Nurburgring Nordschleife in 7minutes 18secounds and was recently previewed to dealers in Europe. It is 200kg lighter than the already lightweight GT2. It is even more powerful than the already legendary and ultimate (of its time) Porsche Carrera GT which only has 612ps. It does 100km/h from a standstill in 3.4 seconds, zero to 200km/h in under 10 seconds and a top speed of over 300km/h.   At a stroke, Porsche has created the ultimate 911 Turbo. This is like the 911 GT3 RS but with '21' added on the scale of 10. The GT2 RS makes 620ps from its 3.6liter twin turbocharged engine. The whole thing runs through the rear axle which I believe must be aided by the PASM or Porsche Stability Management System. The RS also has a roll cage like the GT3 RS in place of its rear seats. But I have to say that in other words, they have created a car that may be potentially the scariest road going Porsche of them all.   This car may reaffirm the 'widowmaker' nickname of the original GT2 and it will surely enter the annals of almost everyone's top 10 911s ever produced. The cost for owning one of these, limited to 500 units monster? It starts at 240,000Euros. All the Porsche I ever wanted was the GT3 RS. Now they've done it by moving the goalposts of 911 heaven again.
