2011 Lexus LFA


Gone are the stickers and the camouflage, the wild spoilers and the additional XXL high-beam lights, the roll cage and the stripped-out interior. The gleaming white wonder posing in pit lane at the Nürburgring Formula 1 circuit looks like a distant relative of the race car that competed in the twenty-four-hour endurance run earlier this year. What we see here – four weeks prior to the official launch at the Tokyo Motor Show – is the first undisguised production car, one of only 500 LFAs to be made, estimated to cost a breathtaking $350,000 to $400,000. This dramatically different Japanese sports car combines high technology with maximum user-friendliness. It is a blend of extreme engineering and exquisite craftsmanship, top-notch performance and easy accessibility, uncompromising driver involvement and total control. There are more powerful and faster sports cars out there, but very few deliver their talents in a more focused and more emotional manner than the new Lexus flagship.
When development of the LFA started in the Toyota skunk works some nine years ago, the idea was to create a new high-end aluminum-spaceframe sports car that would feature a V-8 or a V-10 and, most likely, a dual-clutch transmission. But the brief kept changing as the project was transferred from Toyota to Lexus, where light weight became a higher priority. Chief engineer Haruhiko Tanahashi remembers why: “We knew we had to challenge the best in terms of performance, handling, and roadholding. But under the Lexus brand, we also needed to emphasize refinement, comfort, and style. Since these elements are not exactly weight-neutral, the whole approach had to be reconsidered at a point in time when the project was already two-thirds down the road.” At that late stage, the LFA team switched to a molded-carbon-fiber unibody structure, an automated-manual gearbox, and an innovative ten-cylinder engine intended to be as light as an eight and as compact as a six. Despite these efforts, the 3263-pound Lexus doesn’t quite match such lightweight rivals as the 2975-pound Ferrari 430 Scuderia or the 3175-pound Porsche 911 GT2.
The carbon-fiber center tub did save 220 pounds and is four times as rigid as the previous spaceframe design, and it also taught Lexus some valuable lessons with regard to future higher-volume production concepts. Using heavily modified, laser-equipped Toyota looms to weave the fibers in new high-strength patterns, the Japanese created a very stiff passenger cell composed of three moldings. For maximum strength and rigidity, embedded aluminum collars were developed to attach the front and rear subframes. To achieve the desired 48/52 percent front/rear weight distribution, the engineers opted for rear-mounted radiators and a transaxle, and they set the front-mounted engine back in the chassis. A torque tube connects the V-10 engine to the automated six-speed transaxle. In the front, the LFA relies on an aluminum-intensive control-arm suspension and compact springs; low-friction dampers with remote fluid reservoirs; and a tubular antiroll bar. In the rear, we find a multilink arrangement consisting of four transverse arms, a compact upright, and a pair of angled springs and dampers. The tires are asymmetrical-tread twenty- inchers by Bridgestone, 265/35 in the front and 305/30 in the rear…
As one would expect in a car that’ll cost about as much as twenty-five Corollas, the LFA boasts carbon-ceramic brakes for stupendous deceleration and consistent pedal action. The monoblock calipers accommodate different-diameter pistons to push the pads against the rotors in a more even and progressive manner. That this high-tech coupe is all about sweating the details also becomes obvious when one examines the steering. The fixed-rate, electrically assisted device combines light weight with a lot more feel than is typically relayed by nonhydraulic systems. Even the flat-bottom steering wheel is quite special, in that it blends a carbon-fiber upper and a heavier aluminum lower to enhance the self-centering effect. Although the shift paddles are symmetrical, they’re calibrated such that downshifts require more effort than upshifts. The exhaust, too, is anything but conventional. It’s not so much the equal-length dual-pipe system with the two integrated mufflers and the three tailpipes that sets the tone but the different sound channels that run through the cabin. Channel one penetrates the firewall below the dashboard, channel two aims at your ears via the upper cowl opening, and channel three takes shape as a lower reflector behind the seats.
Unlike the race car that we previously sampled [October 2009], the production LFA’s cabin is as lavishly equipped and as beautifully executed as any other Lexus. The seats are comfortable and supportive, and the materials – mainly leather, aluminum, and carbon fiber – are first-class. The sculptured instrument panel is dominated by a single round display that incorporates the full-size tachometer, the small digital speedometer, the shift indicator, and about two dozen secondary functions that can be summoned via a control on the steering wheel, opposite the starter button. So whenever you’re tired of looking at the classic mix of water and oil temperature, oil pressure, and fuel level, don’t hesitate to call up the lap timer, the tire-pressure monitor, or the trip computer. Although at a glance the displays look as analog as in a British roadster from the 1930s, what you see is actually digital – even the needle of the rev counter, which had to be computerized to match the eagerness of that musical V-10.
We drove the LFA on secondary roads, on the autobahn, and on the Nürburgring grand prix circuit. Are we impressed? Yes and no. There are only two areas – engine characteristics as well as clutch and gearbox action – where the ultimate Japanese sports car fell somewhat short of our expectations. Codeveloped with Yamaha, the 552-hp, 4.8-liter V-10 is without a doubt a mechanical masterpiece. It has been skillfully engineered, with almost telepathic throttle responses that underline the car’s strong motorsport connection, acoustic performance that is positively addictive, and a willingness to rev that is refreshingly uninhibited. In addition, this engine is commendably smooth-running, remarkably powerful, and reasonably torquey. It will thrust the LFA from 0 to 62 mph in 3.7 seconds and on to a top speed of 202 mph (according to Lexus). Impressive enough – but by no means in an orbit of its own. A Nissan GT-R, which is a fraction of the price, shaves at least one-tenth off the LFA’s acceleration time. A Corvette ZR1 is a few clicks faster overall. And both cars produce significantly more torque at lower rpm. That’s where the real dilemma of the Lexus lies: too many revs for not quite enough grunt, 6800 rpm for 354 lb-ft of torque. On the racetrack, the LFA formula works very well. On the road, however, you often find yourself with 4000 or 5000 rpm to play with when what you really need is an instant kick in the butt…
The automated six-speed transmission is the other Jekyll-and-Hyde element that fails to score ten out of ten. Although there are seven different shift velocities to choose from (they range from 0.2 second to a leisurely 1.0 second), the clutch fitted to both test cars would occasionally slip, respond slowly, or even refuse to act. Strangely enough, the system worked better under stress on the circuit than on the road, where second-gear uphill bends and brisk takeoff maneuvers would sometimes confuse the electronics. Although these glitches were in all likelihood related to the cars’ early production status and to the extremely hard use, it deserves a quick fix – after all, just about the last thing Lexus can afford is a quality problem associated with its halo model.
As it is, the crowd-stopping coupe from Toyota City excels in other, rather more subtle areas. Like overall balance, the ability to communicate, and the transparency of the controls. While it may not look particularly light, the Lexus feels like a superfit athlete – from the free-revving engine to the responsive handling, the intuitive steering to the riveting brakes. This perception of lightness adds a new dimension of agility that only true supercars can match. Take the suspension, which offers the best of both worlds: a little understeer to warn the timid, a little oversteer to reward the brave. Take the steering, which is as genuine as your best friend’s handshake. Take the reassuring brakes, which are perfectly easy to modulate.
Out of the four available drive modes that can be selected via a knob on the dashboard, we didn’t try Wet for obvious reasons, and we disliked Auto for its slow and jerky action. Normal is fine for two-lane roads, but Sport adds quite a bit more spice to the drivetrain and stability control menu. It permits higher revs (the gauge starts flashing whenever the 9000-rpm redline approaches), more ambitious shift points, and a more entertaining handling balance. For a seriously aggressive cornering attitude, stability control can be switched off. But in reality, you don’t want to play hooligan, because this car is more about clarity and purity than about showmanship. Gifted with a drag coefficient of 0.31 and equipped with an active tail wing, the LFA retains this dynamic unambiguity on the autobahn, where it tracks with precision; soaks up low-frequency, big-effect pavement imperfections with aplomb; and closes the challenging 150-to-200-mph gap with surprising vigor. This is a seasoned, high-speed tool that copes competently with 125-mph lane changes, 150-mph blind crests, 175-mph bends, and 200-mph stops.
Built on a dedicated line in the Motomachi plant at a rate of no more than twenty units a month by a crew of 140 engineers and specialists, the LFA is as much one man’s dream as it is a team effort. “During the presentation at the ‘Ring, the ‘I want one’ factor has indeed grown considerably,” admits Tanahashi-san. “What remains a dream for me will hopefully turn out to be a thrilling drive for our customers. Is there going to be a follow-up project? Well, I think this car deserves a second chapter. Whatever the next iteration of such a brand-shaper may be, it definitely needs to be right for its time.” Want to know more on how to actually buy one of the 500 LFAs?

2012 BMW 650i Coupe


More often than not, convertibles launch after an automaker has introduced a conventional fixed-roof variant, but the 2012 BMW 6-series is a break from that tradition. Instead, the automaker debuted the 2012 650i convertible earlier this year, just in time for it to arrive in the U.S — where 6-series convertible sales are double that of coupes — for prime drop-top driving season.
That said, BMW isn’t leaving buyers looking for a large, premium coupe out in the cold. The automaker just released the first official photos of the new 2012 650i coupe, which is scheduled to reach U.S. showrooms by the fall of 2011.
Predictably, the new 650i coupe is a line-for-line clone of its convertible sibling below the beltline. Previewed by the 6-series Concept shown at the 2010 Paris Motor Show, the new 6-series coupe’s exterior form is clean, sculpted, and a refreshing change from the previous model. Designers labored to lend the coupe and convertible similar rooflines, although the hardtop does receive slender C-pillars, which incorporate the brand’s distinctive Hofmeister kink.
Despite growing almost three inches in length and 1.5 inches in width, engineers labored to prevent the 650i from simultaneously gaining weight. Finalized specifications have yet to be released, but the new 6 extensively uses lightweight materials. Aluminum is used in coupe’s doors, hood, front shock towers, and a majority of the suspension components, while the front fenders, trunk lid, and outer roof skin are crafted from composite materials.
Although Europeans will be able to opt for a 640i model with a turbocharged 3.0-liter I-6, the 6-series coupe will only be sold in North America as a 650i. The 650i cars make use of BMW’s twin-turbocharged, 4.4-liter V-8, which is rated at 400 horsepower between 5500 and 6400 rpm, and 450 pound-feet of torque from 1750 to 4500 rpm. BMW’s eight-speed automatic transmission is standard equipment, but a six-speed manual is optional — and, remarkably, only so on cars bound for North America. Regardless of the gearbox, expect the 650i to be quite quick: BMW says either car is capable of sprinting from 0-60 mph in 4.9 seconds, and is electronically limited to a top speed of 155 mph.
Like its four-door relative, the 5-series, the new 650i makes use of BMW’s electronically controlled dampers. Drivers are allowed to dial in ride quality from behind the wheel, selecting from settings ranging from comfort to sport. A new active roll stabilization system is optional, and counteracts lean in corners by adjusting hydraulic actuators in the front and rear anti-roll bars. BMW’s active steering system is once again available, but has been revised to incorporate rear-wheel steering. Unsurprisingly, advanced technology isn’t relegated to the chassis itself. BMW’s ubiquitous iDrive system again appears within the 650i’s cabin, but now incorporates a 10.2-inch high-definition LCD screen. Audiophiles may delight in pairing that infotainment system with a new 16-speaker sound system developed by audio specialist (and longtime Audi partner) Bang &Olufsen. An optional driver assistance package adds lane departure warning and blind spot detection systems, along with a new three-dimensional head-up display. Active cruise control is also available, as is BMW’s night vision system, but those seeking additional nocturnal vision can also opt for new adaptive LED headlamps.
Official pricing won’t be announced until closer to the 650i’s official U.S. launch date, but expect the coupe to carry a manufacturer’s suggested retail price in the low-to-mid $80,000 range — slightly above the $79,325 asking price for a 2010 model, yet far below the $91,375 base price for a 2012 650i convertible.

Mercedes-Benz


The mighty Unimog is 60 years old, and Mercedes-Benz is celebrating with an all-new amphibian-inspired Unimog concept that hints at off-road vehicles of the past and future.
Based on the current U 5000 chassis, the “Concept Design 60 Years Unimog” (something got lost in translation) is an homage to extreme off-roaders past. With prominent fenders and a bright green hood, it’s also intentionally reminiscent of a poison dart frog. Mercedes-Benz said the comparison is accurate, as the both the frog and the ‘Mog are “extremely mobile both in water and on land.”
Like the first-ever example that rolled out of the plant in Gaggenau, Germany, on June 3, 1951, the 60 Years Unimog is an open-air vehicle, with seats the driver and passenger can easily hop into. Considering that the incredibly awesome Unimog is frequently seen in war zones and construction sites, it’s a safe bet a roof will be standard equipment for years to come.
As far as sheetmetal, or lack thereof, Mercedes claims the concept represents the new “face” of its commercial vehicles. Though we find it eerily reminiscent of a dirt bike trapped under the hood of a GLK, it’s nice to see an automaker go through the effort to draw up a radical concept for such a function-first vehicle — especially one that’s been through so few exterior renovations during it’s long and iconic production run.
The designers also made sure to highlight one of the Unimog’s most important features: an incredibly beefy suspension with massive coil springs. All that suspension travel allows the truck to seemingly defy the laws of physics by keeping all four wheels on the ground even at the most extreme angles. On the 60 Years Unimog, the springs are painted a shade of red that’s sure to make the marketing department and dealers smile.
According to Mercedes-Benz Special Trucks director Yaris Pürsün, the folks at Mercedes had fun building it, too. “From the very beginning there was a unique spirt of cooperation. It has been a very emotional project which we all became very attached to,” he said.

Lamborghini Gallardo LP540 GT3 Generazion 2011


DMC, a tuning firm from Germany has released the 2011 Lamborghini Gallardo LP540 GT3 Generazioni for paying tribute to the twin Fabio Babini and Matteo Zucchi which have recently won Silverstone leg of this year’s Blancpain Super Trofeo. The new LP540 GT3 Generazioni is basically a Lamborghini Gallardo LP540 with new aerodynamic body kit and a modified engine.
The new aerodynamic body kit for GT3 Generazioni include new GT3 front and rear bumpers, carbon spoiler, extra wide fenders, carbon fiber enhanced side skirts, new rear bumper diffuser, restyled rear wing in carbon fiber or fiber glass as well as a set of 20-inch forged wheels Diamond. The cabin also gets a little carbon fiber treatment for steering wheel, door openers, as well as the seats.
While for the engine modification, DMC provides an ECU remap for the LP540′s 5.2-liter V10 engine, improving power output from 540 HP to 566 HP and 475 lb/ft of torque.

2011 Ford F-150 Raptor SupperCrew


Ford struck its competitors hard when it introduced the 2010 F-150 SVT Raptor SuperCab, calling it the “first-ever, high-speed, off-road performance truck.” With its wide stance and 133-inch wheelbase, not to mention the blacked-out grille and bold graphics, the Raptor had a look all its own, and it excited passions among truck enthusiasts. Some 8614 Raptors sold in 2010, and sales are off to a strong start this year.
But there’s room to quite literally expand the model. The new 2011 F-150 Raptor SuperCrew has a 145.2-inch wheelbase, gaining 12 inches over the SuperCab. All the extra length goes into the second row, where three rear passengers enjoy 43.5 inches of legroom. A 5.5-foot cargo box trails behind. Maximum towing capacity jumps from 6000 to 8000 pounds.
It would have been too obvious to introduce the Raptor SuperCrew in the desert. To emphasize the point that the brawny Raptor SuperCrew is more than a factory-ready Baja pre-runner, Ford chose the Smithers Winter Test Center, in Michigan’s Upper Peninsula, for the press preview. Fresh snow ensured a divertingly low coefficient of friction. While there were no opportunities to fully flex the long-travel suspension (11.2 in/12.1 in f/r) — neither jumps nor whoop-de-do’s were included — all sorts of other tomfoolery was possible and it became pretty apparent that the engineers have worked out the best compromises in chassis and suspension development. In short, they’ve taught the foxtrot to a pachyderm.
Masked bandit look
The Raptor SuperCrew clearly announces its uniqueness, establishing a much different look from the F-150. The blacked out grille spells the Ford name in bold letters. Black 17-inch wheels wear 315-millimeter-wide, 35-inch-tall B.F. Goodrich off-road tires. The Raptor series is the first OEM application for Fox shocks, whose presence is quite apparent through small openings in the front bumper and under the black fender flares at the rear. An optional matte-black graphic emblazoned with the Raptor name covers the hood, reducing glare. The hood’s nostrils and the front fenders’ vents provide enough outlets so that you can all but hear the truck snorting. For the cargo box, the optional “digital mud” graphic has so far been chosen by 43 percent of buyers.
Choose classically handsome or garishly bright interior
The standard interior includes exceptionally well-bolstered front seats trimmed with handsome black leather. The optional package adds orange seat and door inserts front and rear as well as matching dashboard and center-console trim. We didn’t sample this, but found ourselves satisfied with the black and silver and wondering whether the orange wouldn’t seem somewhat lurid after a few years. Beautiful chrome accents flourish on the shifter and center-console cupholders. The second row may be comfortable, but it lacks amenities like a foldable center armrest with integrated cupholders. The seat bottoms flip up in one easy motion to increase storage. Then they release with one pull of a handle and drop back down..
‘Productivity’ can be measured and displayed
In addition to the large centrally mounted display screen, the Raptor SuperCrew features a new 4.2-inch “productivity” screen between the tachometer and speedometer. With buttons on the lower left of the steering wheel, the driver selects from various menus that convey information about off-road and towing performance. For example, the front wheels’ turn angle can be precisely dialed in for crawling, with a corresponding graphic clearly conveying the information. Differential locking functions are another menu item.
The bigger V-8 is now standard
All Raptors now come with the 6.2-liter SOHC dual-spark V-8, as the original standard 5.4-liter V-8 has been dropped from the lineup. Putting out 411 hp and 434 lb-ft thanks to a unique cam profile and bespoke tuning, the engine smoothly connives with the six-speed automatic to make the 6200-lb brute to get up and move out. Plenty of torque is on tap, no matter what ratio is chosen. The subject of using the manual mode for changing gears is a bit of a sore point, though, for instead of being able to slot the shifter into a dedicated track and using push/pull to change gears, you have to mess with a toggle switch on the shift lever. On the other hand, you have to credit Ford with getting it right on the traction control. One push of a button changes the AdvanceTrac to a sport mode that keeps you from being sloppy but lets you throttle-steer this 232.1-in giant at will. We were impressed with how well the Raptor SuperCrew got through a slalom course under very slick (read: hilariously entertaining) conditions. Feedback from the superb, hydraulically assisted steering makes one glad Ford didn’t go with an electrically boosted system.
The essence of a sport truck
Indeed, all the recalibrations of chassis and suspension to accommodate the Raptor SuperCrew’s extra length and weight (200 pounds) pays off in an extremely well-mannered rig that handles with complete predictably. Before long, you forget about the bulk and just delight in the responsiveness, shaving ever closer and closer to the cones in the slalom. Body roll also is well managed. The Smithers facility included a 1.4-mile road course — loose snow atop bare ground — that proved the Raptor SuperCrew’s relative nimbleness. With the engine bellowing stoutly, you could power out of the turns with the tail slightly out, always confidently feeling the edge. And with such wide tires, it’s an edge that’s not easily reached. Leaving Smithers for Sault Sainte Marie over patched Upper Peninsula highways, you find the ride is almost cushy. The truck tracks straight and doesn’t wallow. And there’s no chassis flex or rattling of the cargo box.
Transcending the Crotch-Grab
Big, bold, and exciting, the Raptor SuperCrew combines a plethora of off-road design cues for a singular appearance. And it has the performance and capability to match. Yes, it’s expensive at $45,290 including destination charges. Ford doesn’t have to release fuel economy figures because of the truck’s weight, but you know it’s going to be a crotch-grabber. But to those in the know, it’s extremely desirable and even — in the opinion of one truck magazine editor at the preview — collectible…
