2016 Audi RS7 Very first Drive: Exact same Thrills, Plus Detail Refinements

Initial Drive Review


arrow



Still one step ahead of the class.


We called the RS7 “Quattro’;s ideal function yet,” in a recent comparison test, which it won. The car is now even greater. For 2016, the Audi RS7 sees subtle upgrades inside and out, significantly like those that apply to its stablemates, the A7 and the S7. The RS7 already was the freshest of the trio, getting arrived right here for 2014, so these modifications are even less clear.


Outdoors, it gets new head- and taillights related to these that grace its less strong siblings. But the style of the front bumper and reduced air intakes remains practically identical to the pre-face-lift models (which must please present owners). With its big 20- or 21-inch wheels and matte-aluminum décor, the RS7 is the most impressive and perhaps the most harmonious in the lineup. Neither garish nor more than-the-top, it does look imposing. With its new headlight contour, it reminds us of the original Audi Sportback concept that preceded the A7 on the show circuit.


Inside, the RS7 gets revised instrumentation with a larger driver-data display (now with Google Earth) between the tachometer and speedometer. An enhanced electronics architecture helps upgrade the graphics and the integration of the infotainment and telematics systems, now using LTE communications when obtainable, and it is compatible with Siri Eyes Free. The MMI interface also gets refinements, generating it easier to use, and the night-vision display is also enhanced. New colour and wood alternatives dress out the cabin.






Such luxuries have their appeal, but what tends to make the RS7 truly desirable is that it is one of the greatest efficiency sedans (properly, hatchbacks) of all time, and there are no adjustments to its mechanical specification. It makes use of the very same fairly compact, twin-turbocharged 4.-liter V-8, out of which Audi squeezes a healthful 560 horsepower and 516 lb-ft of torque, the latter of which is served across a lofty plateau that stretches from 1750 to 5500 rpm.


The engine supplies wonderful straight-line performance: Audi claims it will run from zero to 62 mph in 3.9 seconds, but we measured 3.4 seconds to 60 mph in a 2014 model. In Germany, the RS7 provides 3 distinct prime-speed governors based on the wheel/tire package the leading one particular lets it run all the way up to 190 mph. The U.S. most probably will get the mid-level governor, rated at 174 mph. Not a problem.


With the European fuel-consumption rating, nevertheless, Audi appears to be joking. The official rating of 25 mpg would demand ruthless asceticism. Figure on 20 mpg if you are feather-footing. Using the power liberally will reduce that in half. We saw 9 mpg in that comparison test more than a fairly brief (150-mile) run of spirited motoring. With only 420 horsepower to tempt us, our extended-term S7 is averaging 21 mpg.






Not just supercar rapidly, the RS7 sounds off with a corresponding, ultra-aggressive tone, menacing even at standstill. Wind out the gears, and the exhaust pops audibly at upshifts easing off the gas produces a furious crackle the entire symphony of intake, combustion, and exhaust underscores the reality that there are tightly controlled but huge explosions raging in the combustion chambers of this engine. The ZF-supplied 8-speed automatic responds so rapidly that couple of will miss the S7’s dual-clutch box.


Never silent, the RS7 is nevertheless easily maneuverable and controllable on the street. Step up the pace, and it exhibits remarkable agility. The torque-vectoring rear sports differential is virtually overly eager to assist the driver throw the RS7 into corners it can really feel a bit artificial at occasions. Way up at the limits of adhesion, the powertrain, sports differential, and assistance systems have to work overtime and can no longer disguise the big hatchback’;s mass. Audi claims a curb weight of 4398 pounds our comparison-test instance registered 4453 on our scales, heavier than even the portly BMW M6 Gran Coupe and the Mercedes-Benz CLS63 AMG.


Anticipate the 2016 model’s price to remain near that of the existing model, which lists for $ 107,425, prior to choices. It is straightforward to run it up more than $ 130K. If you are significant about driving, start by choosing the RS7 Dynamic package that Audi not too long ago added to the range: It packs a sports-tuned steel-spring suspension instead of the regular air suspension and comes with the amazing efficiency exhaust method. Down the road, we anticipate that Audi will bump up the power, maybe to 600 horsepower, to match or best the BMW and Mercedes-Benz competitors that now stand at 575 and 577, respectively. Till then, we stick to our verdict: This is Quattro’;s greatest perform however.

Who should swerve and to where to avoid the head-on crash in the same lane?





94f9c Brandfort head on pic


This is not an easy question to answer. We referred this rather interesting question to well-known crash reconstructionist Stan Bezuidenhout and would like to share his response!


Question:


“Watching vehicles overtake in places they should not made me think about the following:


1. If I’;m in my lane and faced a vehicle head-on – 1a. which way would I swerve? 1b. which way would the other vehicle swerve?


2. If I’;m the overtaking vehicle – 2a. Do I swerve? 2b. Do I stay in the lane and move closer to the vehicle I’;m overtaking?


We know this is a problem that won’;t go away easily – can tips be made available on TV etc BEFORE Christmas holidays come?  Another problem are drivers that “KNOW THE ROAD” as they travel it most days (eg George/Oudtshoorn) – but then the saying of “familiarity breeds contempt” is true and other drivers slowing down on a section of road UNFAMILIAR to them get labelled as slow/bad drivers.


Just a thought for tips for the up-coming holidays.


Regards”
Response: 


“Faked Right Syndrome” and how to prevent it…


The questions posed by Ms Liebenberg were very insightful and rather complex to answer at the same time. Her awareness of this and her request fills me with confidence regarding the future of road safety in South Africa. If road users are capable of approaching an issue that complex with so much insight, then perhaps all our combined efforts are starting to pay off.


Let me set the stage for my answers and clarify some core concepts that need to be understood in this context. Firstly, there are legal issues; According to the so-called “reasonable man” principle there are some duties on a driver when faced with this situation (a vehicle on your side of the road).


Be that as it may, the challenge is (more often and not) proving your innocence in court and defending your actions. There are circumstances under which improper investigation at the scene and a lack of knowledge for some critical syndromes at play can expose you to risk of prosecution or even a guilty verdict.


Let’s just explore this “the other car is on my side” scenario:


Imagine driving down the road (perhaps at night), on a 2-lane stretch. You see a vehicle approaching and become aware that this vehicle is actually on your side of the road or drifting over towards you side, predicting a head-on collision.


Now you have some options to consider. You could:


a)     Stop dead in the road (and risk still being run into).


b)     Move over or swerve to the left (away from the approaching threat) but what if the other car keeps moving over and “follows you” until a collision occurs?


There is a third option and you will be surprised at how many people choose this option: You can argue that – since this approaching vehicle is in your lane – you would be best served to move (or swerve) over into his (the wrong) lane so that you can both pass each other “on the wrong side” but at least prevent a collision.


The problem is when that other vehicle notices at the last minute (wakes up, looks up or responds top your movement) and then tries to “fix the problem” by swerving back to its own lane. Then you collide head-on with that other vehicle, on ITS side of the road!


This is called Faked Right Syndrome (Originally Faked Left Syndrome, in the USA) and places you in a very serious predicament: You would need to PROVE that you were acting in self-preservation and not illegally travelling on the “Wrong” side of the road, in the face of approaching traffic.


How will you prove this? Quite frankly, it is rather complex and would require proper forensic analysis with a specific interest in PDOF (Principle Direction of Force), Crush (damage depth) analysis, Departure Angles, Occupant Kinematics and Vehicle Dynamics (rotation, etc). It is possible, but it can only be done if very detailed at-scene investigation and measurements are done properly.


But this article is about advice on how to prevent it – not analyse it. So we return to the questions received from Ms. Liebenberg. She writes:


Watching vehicles overtake in places they should not made me think about the following:


  1. If I’;m in my lane and faced a vehicle head-on –

1a. which way would I swerve?


1b. which way would the other vehicle swerve?


In terms of law, you are required to do at least the following things:


a)     Flash your headlights to alert the other driver.


b)     Blow your car horn (hooter) to alert the other driver.


c)     Apply brakes and slow down or stop to prevent a collision.


d)     Move over to the left to prevent a collision.


Realistically, however, few people would be in a position to do all this at once (don’t get me started on driver training standards!) and there are cases where these options are not all available.


Flashing your headlights might be useless if an approaching driver has fallen asleep or is unconscious due to a medical emergency. But this is one thing that you can do without too much effort. Flashing your lights can typically not “go wrong” too badly.


Blowing your car horn is only effective if the other driver is conscious or has windows open (in cases where vehicles are loud, like trucks). But again – this is easy enough and cannot really go “wrong” or conspire against your desired outcome.


When it comes to applying brakes, our analysis of these kinds of collisions often prove to be the last resort. This is where driver attitude starts introducing a component of psychology that requires a lot of work to improve.


In our experience, on roads in South Africa, people tend to react less defensively when they believe they are “right.” We have actually attended and investigated crash scenes where vehicles collided head-on with more than 2 vehicle widths’ worth of space the driver “that is right” could have used to move over and prevent the collision.


We call this passive aggressive vigilantism. People tend to believe that they will “do what everyone else does” and “refuse to submit to someone who is wrong.” This is the passive aggressive component. People tend to have the “well, then I will just stay right here and do nothing” approach. Then they use this and extend their “argument” to include an additional component: “I will teach you a lesson.” Road users tend to take the law into their own hands (doling out punishment) by opting not to be “intimidated into submission.” We have personally seen this result in multiple fatalities in numerous cases we investigated.


So the next piece of advice we can give is: “There are no living heroes.” Essentially, road users need to understand that being right is no guarantee of immortality. You die when you are injured badly enough, whether you are right or wrong.


There is no moral in survival – you should do whatever it takes to survive – and this includes braking (and being the loser of the game of chicken). So people need to learn to be willing to “accept defeat” and to survive with that title rather than “dying while being right.”


A message on your tomb-stone that reads “Here lies John. He never backed off from a fight. He proved this. Once.” will not be nearly as much fun as seeing your loved ones and family for another day. Period.


Swerving or moving over is also an action you can take (notwithstanding Faked Right Syndrome). If you move over to the point of no return, but fail to slow down or stop at the same time, you might be the very source of adequate energy to cause a fatality. The less SPEED you have, in relation to the other vehicle, the greater your chance (and theirs) of recovery. So slowing down and moving over remains the best and only option, really.


But there are cases where moving to the left is simply not possible.


One example is where there is a cliff to your left and where moving or swerving to the left would expose you to falling over the edge. It might also not be possible if there is a wall or embankment on your left and where there is no shoulder.


In these cases, moving over to the “wrong” side might be your only option. Our advice would be to rather fit an in-vehicle video recording device in your vehicle (they are now freely available and a wide range of models and features are included in options). This way – if this (Faked Right Syndrome) ever happens to you, evidence would be available to clear your name and justify your actions.


We live in a complex world and crash cases are enjoying more court time and prosecutor skill now than ever before. More and more crash cases are relying on expert testimony. You’d be best served to ensure that you take steps to have evidence available.


Miss Liebenberg further asks:


2.     If I’;m the overtaking vehicle –


2a. Do I swerve?


2b. Do I stay in the lane and move closer to the vehicle I’;m overtaking?


In short – if you are the overtaking vehicle and you have been caught by surprise (there are places in the country where broken barrier lines are installed in locations where it is actually not safe to overtake) – you should brake as hard as is safe to do so and return to your lane as quickly as possible. But there are additional elements here as well:


Firstly, you should never overtake in a way that does not enable you to see far enough ahead (with your own eyes – inconsiderate of whether you are “allowed to” or not). Get to know your vehicle and its performance characteristics and consider you limitations (your eyes might perform less effectively at night). Let good sense be your guide: If you cannot see it, you cannot plan for it, so assume there IS a vehicle approaching at all times and act accordingly – whether you can “see its lights” or not.


But then we also need to address the issue of the vehicle being overtaken. WE have seen – too many times – how one vehicle overtakes another and makes an error in judgement, facing an approaching vehicle, then the vehicle to the left (being overtaken) does not actively contribute to the risk mitigation strategies of the overtaking driver. If you are being overtaken and you see an approaching vehicle, immediately move over to your left (safely, of course) and allow the overtaking vehicle the space and opportunity to return to your lane safely. Apply brakes and fall back if needed. This simple act of due consideration could save a life. Or many.


Miss Liebenberg adds:


Another problem are drivers that “KNOW THE ROAD” as they travel it most days (eg George/Oudtshoorn) – but then the saying of “familiarity breeds contempt” is true and other drivers slowing down on a section of road UNFAMILIAR to them get labelled as slow/bad drivers.


In response to this, we should also look at road design and signage. If roads are poorly marked, ineffectively regulated (no signs and warnings) or poorly maintained, unfamiliar drivers will be forced to employ risk homeostatic strategies. They’ll have to do something to reduce their (perceived or real) risks.


When you then combine this with familiar drivers (moving faster) you get stuck with something called Traffic Friction. Traffic Friction is the effect on the combined global speed of movement on traffic as the result of the interference caused when slower and faster drivers use the same section of road.


The outcome is that slower (perhaps intimidated) drivers start slowing down even more for fear of getting “run over” by the other “maniacs” on the road. The faster drivers, in turn, get frustrated by the slower drivers and start “queuing up” behind them. If some drivers are then more confident or aggressive than others you start seeing some being willing to overtake several or tens of slower vehicles, increasing risk beyond reasonable levels.


If you also consider slower drivers due to their involvement with their cell phones, smoking cigarettes, putting on make-up or engaging in other distracting acts, you have a recipe for disaster yet again. Other drivers now become frustrated, aggression levels increase and the propensity for taking risk increases enormously. But the original concerns or root cause was the “slower driver” and not the “speed demon.”


Finally, there seems to be a general lack of awareness for the simple “Keep Left, Pass Right” rule. When slower drivers choose the “fast lane” and faster drivers get frustrated and start “swerving in front of other road users” to “teach them a lesson,” we have yet another recipe for disaster.


The best advice we can give would include planning (giving yourself enough time to travel), sound judgement (become familiar with your vehicle and know its capabilities and limits), obey the law (Keep Left, Pass Right), adhere to speed limits (60Km/h in a 120Km/h zone is as dangerous as driving at 160 Km/h in a 60 Km/h zone) and be courteous. The road does not, in fact, belong to you alone.


If you consider yourself a visitor to our roads, as is everyone else and allow yourself to “allow others to use the road,” you would immediately find yourself slowing down, relaxing and just “letting traffic be…” Stay calm, keep smiling and remember that most other road users do not actually know you in person.


If you can follow these simple steps you can enhance your well-being, enjoy travel more and stay with us just a while longer.

2014 Chevrolet Corvette Convertible Tested: Very same Sting, Much more Rays

Instrumented Test

Same sting, much more rays.


Pop open the electronically actuated door of any new Corvette Stingray and the odor of plastic resin greets you. Smelling like a martini created with counterfeit Chinese vodka, the C7 coupe cannot go al fresco quickly enough—via its standard removable roof panel—when it’s been sitting in the sun. Perhaps GM requirements to set up a perfume dispenser like the one in the Mercedes-Benz S-class. If it does, can we get a bacon fragrance?


Or you can just opt for the convertible. It requires only 21 seconds to drop the top, and you can go ahead and pull away from the curb after the method has started the roof works as lengthy as you maintain your speed below 30 mph, which is far more than rapidly adequate for extricating the auto from wherever it is parked.


From behind the wheel, you would never know the coupe and the convertible are distinct vehicles as long as you steer clear of searching in the rearview mirror. Stow the coupe’s targa best in the cargo region and you will even get the identical sunburn. But the ease and speed of operating the 1-button convertible best stand in stark contrast to the triple latches of the coupe’s removable panel. You will get pleasure from open-air motoring more in the convertible because you will be far more probably to motor in the open air.






Some of the usual downsides apply. The convertible has a small trunk, it is much less suited for track days, and it has an awkward profile with the leading up. And yes, as with any soft prime, there are safety concerns. But you needn’t be concerned with overall performance numbers. When it launched the C7 Corvette, Chevy promised that the convertible would provide identical functionality to the coupe. Soon after our initial drive, we had no reason to doubt this assertion, and our testing gear now confirms it. A Z51 package–equipped convertible turned in a efficiency at the test track that really nearly carbon-copied that of our similarly equipped extended-term Stingray coupe.


Both 6-speed manual-equipped automobiles ran from to 60 mph in 3.9 seconds. By means of the quarter-mile, the convertible was a tenth behind at 12.3 seconds and hit the traps at 117 mph, a single mile per hour slower than the coupe. Braking from 70 mph took 138 feet in the convertible, just one particular foot longer. Both cars exceeded 1.00 g on the skidpad. Leading speed favors the a lot more aerodynamic coupe by 3 mph, but a drag-restricted 178 mph in the convertible is certainly not slow. In fact, it’s 7-mph greater than a Jaguar F-sort can attain and 2-mph more than a Porsche Boxster S. So, yes, the C7 Stingray convertible is significantly a lot more than merely the Corvette model least most likely to lead to an inhalants addiction.


Get it out on the street, dial it into Sport mode, and hear the rumble commence to go scary and dark. If you have the $ 1195 functionality exhaust of our test car, it will get much louder, much sooner. (And if you’re behind the wheel of a 2015-model-year Z51 Vette, you do have the exhaust Chevy has rolled the formerly standalone selection into the expansive Z51 package.) Punch it—as you should—but hold on when the nose pops up just a tiny and the rear finish squirms. That is 460 horsepower and 465 lb-ft of torque from the 6.2-liter V-8 creating you feel like some tainted booze is reversing its path through your method. And the sound, oh, it is angry. (Note: The $ 62,995 base value in the specs is for a 2014 auto with the Z51 kit and practically nothing else the non-Z51 convertible begins at $ 58,995.)






With this auto, Chevy has addressed all the shortcomings of the C5/C6 era. There’s nevertheless a bit of Millennium Falcon to the Stingray, which is not fairly as polished as Porsche’s Tie Fighters. The Corvette shakes at idle, and all manner of rumbles and twitches are communicated from the chassis to the driver—and not just via the superb steering. The Corvette moves, it feels alive underneath you, more animal than robot.


Paradoxically, comfort appears much less of a priority than in years previous, but the improvements to the interior and seats made for this generation have resulted in a Corvette that’s actually a lot more comfy than ever. The shifter nonetheless calls for some powerful-arming, and its organic resting point amongst third and 4th gear signifies that you have to be doubly positive you’ve chosen very first, though the auto will launch in third without having stalling. But the manage relationships are outstanding, and if you can’t discover a content location in this cockpit, you may need to have to drive some thing other than a sports car.
