2011 Nissan LEAF Review

July 26th, 2011 Comments Off

Remember the first time you rode/drove an EV? It could have been a battery powered toy car, a golf cart, or even a gas powered car converted to electric, but they all had one thing in common; acceleration like an on/off switch….no modulation. More than 10 years ago Toyota brought the hybrid Prius to the United States and it was one of the first cars with fantastic modulation and packaged in a base car that was previously gas powered. I currently have a second generation Prius in the stable and our staff was lucky enough to test the Chevrolet Volt a couple of months back.

Though electric vehicles and the concept has been around for many years, the car companies are finally putting the ingredients together for EV Nirvana. First you had the gas-electric Prius, then more recently the electric-gas Volt, now comes the 85-100 mile range full EV LEAF. What’s EV Nirvana you ask? We define it as an electric-gas (Volt-like) vehicle with a 300+ mile EV range, then another 300+ miles on gas with a solar roof that would help charge the 24 KW-HR (LEAF-like) battery while in use or parked. The great news is that the three aforementioned models have traces of this EV Nirvana within their DNA.

Design
Early test and design “mules” of the Nissan LEAF used the Versa platform as the test bed and this basic structure carries over to the LEAF. The difference is the Nissan engineers have put a lot of effort into shaping the front and rear of the car for better aerodynamics and since they build the car on a low production line, the attention to detail results in what is seemingly a well built car….almost like a Versa built for Infiniti.
Nissan took a bold shaping approach with the lighting (LED low voltage) and bumpers of the LEAF making it stand out as a very noticeable car…nothing offensive, but it does make a visual statement.

From the side the car looks pretty standard except for the large Zero Emissions decals along the rocker panels. Let’s be clear, the car isn’t a lithe and lovely BMW 3 series coupe, but you’ll read later on that it does serve the general transportation purposes well. Compared to the Volt and Prius, the Volt still reigns supreme on design and the Prius and LEAF are almost a tossup with LEAF getting the edge because of the bold head and tail lights. The LEAF is a little longer (mostly bumpers) and taller than the Prius though they maintain about the same wheelbase.

Driving Impressions
The Volt and the LEAF are much the same in the way they drive. Both are super quiet (Volt-EV mode) and feel very solid. They all have less than 0.30 coefficient of drag allowing them to slip through the atmosphere are freeway speeds with little wind noise. The LEAF is so quiet that Nissan added a back up beeping sound when the car is put in reverse.
Weighing less than the Volt, the LEAF is easier to drive, has lighter steering, stops faster and feels zippier around town even though the Volt has more power and better acceleration. Cornering is a different story primarily due to the Bridgestone Ecopia tires on the LEAF; great for rolling resistance, but relatively poor in handling.
Our test car had a fairly high and flat roofline allowing for great headroom even while seated in the back seats. Unfortunately, the legroom back there does not match and anyone taller than 5’ 10” will have the person in front moving their seat forward. Also, the pillar between the rear door and the hatch is fairly wide and causes a decent blind spot, maybe next year Nissan will offer lane change proximity sensors.
Though the dash is laid out well, it’s relatively tall in front of the driver and if someone were say 5’ 4” and below, they might have trouble seeing over the dash due to the LEAF missing a manual seat height adjustment that is typical in European cars.

Comfort and Convenience
Our testers really liked the LEAF’s simplicity in the dash and especially the controls. Nissan really put some thought into how to package the user interface. The car is void of excess buttons and controls even though it comes loaded with Bluetooth®, cruise control, USB, back up camera, full sound system with satellite radio and a very efficient HVAC package.
Another great feature that is standard in the LEAF is the CarWings application available for your Smart Phone; it allows you remote monitoring of the charging status, security, and can turn on the interior fan powered through the spoiler mounted solar panel on the roof.
The seats in the LEAF are pretty close to standard Versa seats, not as good as the Prius or Volt front seats. One can argue that since the range is relatively short, the seats don’t really need that much adjustability. We would recommend just a manual lumbar support and a manual driver’s seat height adjustment in order not to weigh the car down with extra motors and electronics.

Probably the biggest difficulty is the convenience of charging; with 110V household current, it takes 14-16 hours to make a full charge. Sure, 220V will help to bring these times down to 4-5 hours, but this adds an additional $2500 for at residence installation and not everyone lives in single family dwelling.
The engineers at Nissan did come to the rescue with ECO mode; it’s just a second click with the palm shifter and it brings on control of the throttle not seen in any other EV or hybrid. ECO mode is like driving ecology for dummies, it takes into account the load on the car and optimizes for the best mileage plus adds in a healthy dose of regenerative braking; in a rough test we saw a 20-30% improvement in charge conservation…this is significant.

For Californians, this true EV will be the key to obtaining a single person Car Pool Lane (HOV) sticker early next year as this provision is going away for the hybrids. This will surely boost sales of this short commuter and local run around car. Unfortunately, with the 85-100 mile range and no back up gasoline engine, one has to plan their trips well in order to take advantage of the EV characteristics.
Outside of California, the owner is in for some annual operating cost savings. If you look at annual operating costs (gas vs. electricity) take your annual gasoline bill and cut it by 60%, that is what it would cost to run the LEAF. Even after tax credits, unless the HOV sticker is important to you, it would take a lot of years to make up for the premium paid for this EV over competing fuel efficient gas transportation from all the big OEM’s.
The same arguments were made when the Prius was gaining support, but people bought those for the fuel efficiency and the rights to enter the green club. It’s that time all over again with the LEAF, just replacing fuel with electricity. We applaud Nissan for bringing this great technology to a passenger car at a fairly reasonable price point along with those federal tax credits.
EV motor and battery technology will continue to get better and we will one day see 300 mile ranges on a single charge with faster charge times and when this occurs, the EV and EV-gas vehicles will be on the road in droves. The LEAF is miles and miles ahead of the on/off acceleration of toys and golf carts; progress has been made.

2011 Mazda CX-9 Grand Touring AWD Review

July 7th, 2011 Comments Off

Pros
Spacious interior for 7 passengers + luggage
Sliding second row seats that recline
Standard equipment list longer than Snoop Dog’s rap sheet

Cons
Exterior is too similar to the less expensive CX-7
Interior materials and designs are boring
The nav screen is hard to read in sunlight
Improved MPG, but not stellar

I always thought the pair of Mazda crossover SUVs, the CX-7 and CX-9, to be some of the most handsome ones on the market when they were introduced back in 2006 as 2007 models. Even in today’s crowded crossover SUV market, the Mazdas are still lookers although the styling is getting a little long in the tooth. While the larger CX-9 shares styling cues with the CX-7, it shares almost nothing else with its smaller sibling. The CX-9 is based on the same platform and shares the same 3.7 liter V6 engine as the Ford Edge/Lincoln MKX, an example of the long-term partnership between Ford and Mazda, which continues even after Ford reduced its stake in the Japanese car maker back in 2008.

2011 Nissan 370Z

July 4th, 2011 Comments Off

Overview
The Nissan 370Z is a brilliant sports car with a strong performance-value ratio. The 2011 370Z comes in Coupe and Roadster versions, with styling that adheres to tradition and history.

The design of the 370Z Coupe is modern, driven by aerodynamics, but the sweeping rear quarter window harkens back to the 1970 Datsun 240Z, the car that started it all. The 370Z Coupe uses a hood, doors and hatch made of aluminum, lowering weight.

The 370Z Roadster with its cloth top has a natural shape and looks good in black. The power top is well-insulated with a good headliner, and it raises and lowers without a manual latch.

A racy 370Z Nismo coupe, a product of Nissan's NISMO performance division, boasts more horsepower, a stiffer suspension, bigger brakes and aerodynamic modifications.

The 3.7-liter engine loves to rev and produces a unique sound and, with variable valves and four camshafts, generates 332 horsepower and 270 pound-feet of torque at 5200 rpm, but much of its power is available at lower rpm. The Z accelerates from 0 to 60 in a quick 5.2 seconds.

Cornering is supremely tight, on a short 100-inch wheelbase, with the rotational pivot point in the chassis in its ideal position of balance, right under the driver's seat. The rigid chassis results in responsive handling, even on uneven pavement. It steers with precision and turns in decisively. It changes directions dynamically. And there are no worries about the brakes not bringing you down.

In manual mode, the optional 7-speed automatic shifts quickly. Drivers can use the paddles or lever. The shifts feel direct, like a manual transmission, thanks to what Nissan calls torque converter lock-up logic. With the 6-speed manual transmission, heel-and-toe downshifting easy. The clutch, gearbox and pedals work well together. A computer-controlled feature called SynchroRev Match will blip throttle for downshifts when you don't do it manually.

The interior is attractive and comfortable. The driver's seat is designed to keep the driver in place. The black fabric that comes standard looks and feels sporty while the optional perforated leather is beautiful. There's also a synthetic suede. The instrument panel moves with the adjustable steering column, while the steering wheel spokes are designed to provide a clear view. The gauges are big and clear, white on black with orange needles.

Cargo space is modest. The rear hatch provides easy access to 6.9 cubic feet of cargo space, far less than the 22 cubic feet in the Chevrolet Corvette. The Roadster's trunk has only 4.2 cubic feet of space, about enough for a couple of duffle bags.

Now in its sixth generation, the Z was last redesigned for the 2009 model year. The sixth-generation Roadster was launched for 2010.

2011 Audi Q7

June 30th, 2011 Comments Off

Overview
The Audi Q7 is a big SUV that's big on refinement, comfort and features. The Q7 is derived from the same platform as the Porsche Cayenne and Volkswagen Touareg, but the Q7 rides on a longer wheelbase. The Q7 is also longer overall than the other two, and it is the only one to offer three-row seating. There are many other differences. We've noticed the Q7 offers a more compliant ride than the Cayenne or Touareg and it's more stable at high speed though less agile both in terms of handling and parking.

The 2011 Audi Q7 benefits from major engine and transmission changes. The 2011 Q7 is available with two new supercharged 3.0-liter V6 engines plus a 3.0-liter TDI turbodiesel V6. All 2011 Audi Q7s are matched to a new 8-speed automatic transmission for better performance and better fuel economy. (A V8 is no longer offered.)

The gas engines are both supercharged 3.0-liter V6s, the standard unit at 272 horsepower, and the new S Line Prestige version at 333 hp. The 3.0-liter diesel delivers 225 hp and 406 pound-feet of torque. Torque is that force that propels you away from intersections and up steep hills, and the diesel's impressive torque gives it an advantage over the gas engines. The diesel is also the easiest on fuel, and the logical choice for those planning on towing.

Every Audi Q7 comes with seven seats and all-wheel drive. Audi has decades of experience with quattro all-wheel drive. Safety features include a blind-spot warning system.

The Audi Q7 competes with other seven-seat luxury SUVs, such as the BMW X5, Mercedes-Benz GL-Class, Volvo XC90. The smaller Lexus GX470 and the more comparable Lexus LX570 are more expensive.

We found the Q7 a paragon of driving elegance and interior refinement.

2011 Audi A4

June 25th, 2011 Comments Off

Overview
The Audi A4 is a superb road car with all-wheel drive, a compliant, well-tuned suspension and high-quality interior trimmings. A premium compact, the A4 comes equipped with leather, automatic climate control and a range of options associated with larger luxury cars.

Audi A4 is available in four-door sedan and Avant wagon versions. They come with a smooth 2.0-liter four-cylinder engine that delivers solid mid-range power for good drivability around town.

Audi S4 is a high-performance version of the A4 featuring a 333-horspower V6, a specially tuned quattro all-wheel-drive system, a sports suspension, and special trim.

2011 Audi A4 models come with a new 8-speed automatic transmission, replacing last year's 6-speed automatic. The navigation system on 2011 A4s includes HD radio, an upgrade over last year. Audi side assist is available. The beige birch wood trim has been replaced by Nutmeg Laurel for some cabin colors on 2011 models. Also new for 2011 is a Titanium Sport package with black trim, 19-inch wheels with performance tires, sport seats, and a sports suspension. Audi completely redesigned the A4 for 2009, and it is as closely related to the A5 as it is to the pre-2009 A4 models.

2010 Lincoln Navigator

June 20th, 2011 Comments Off

Lincoln Navigator combines classic Lincoln design and amenities with the functionality full-size SUV customers demand. For 2010, Navigator’s exclusive AdvanceTrac with RSC is joined by standard Trailer Sway Control.

Trailer Sway Control works in conjunction with AdvanceTrac with RSC to determine from the yaw motion of the vehicle if the trailer is swaying and takes measures – such as applying precise braking or reduced engine torque – to help bring both vehicle and trailer under control.

Unlike competitive systems, AdvanceTrac with RSC utilizes a second gyroscopic roll rate sensor to determine the vehicle’s body roll angle and roll rate. If the unique roll rate sensor detects a significant roll angle, the system applies additional countermeasures – such as applying brakes to one or more wheels or reducing engine power – to enhance vehicle rollover resistance.

2011 Nissan Cube

June 15th, 2011 Comments Off

The Nissan Cube is part of a new generation of boxy small cars that can also be viewed as small crossover SUVs. The Cube sports a square, whimsical body design that houses a large, practical cabin. Small and light, the Cube is easy to maneuver, fun to drive and fuel efficient, with an EPA rating of 31 miles per gallon Highway. Yet it's big on the inside. It seats five people, with miles of headroom and acres of cargo space.

Nissan refers to the Cube as a mobile hub, instead of a car, because it is meant as an affordable, moveable gathering place for young people, their friends, and their music. Its back seat reclines for comfort, and it can be deleted for van-like cargo space. Nissan markets its cube in fashionable lower case, like iPhone and smart fortwo.

The Cube was new to the U.S. for 2009, but it has been on sale for a decade in Japan, and the version sold here is actually the third generation of the product. The Nissan Cube predates the Chrysler PT Cruiser, Scion xB, Kia Soul, Toyota Yaris, and Honda Fit, all of which Nissan counts as the Cube's direct competitors. The Cube is built on the same Nissan B platform as the Versa, a roomy subcompact that also competes with those cars.

The Nissan Cube is powered by a 1.8-liter inline four-cylinder engine, the same engine that powers the Nissan Versa in this market. Buyers can choose between a 6-speed manual transmission or the Nissan-built Xtronic continuously variable transmission, or CVT.

We found the Cube to be perky in the big city and able to keep up with the traffic on the highway. Easy to park, it can make a U-turn in the tiniest of spaces. It made us smile, it's cute, it holds a lot of people and cargo, it's zippy, and it can be easily customized with accessories.

2011 Lincoln MKZ

June 12th, 2011 Comments Off

The Lincoln MKZ gets a new hybrid-powered version for 2011, joining a lineup of midsize luxury sedans that was thoroughly updated for 2010.

We found the Lincoln MKZ quite pleasant, with a spacious, understated interior, and a well-balanced combination of ride comfort and easy handling. The MKZ seats five, it offers ample leg and hip room front and rear for four, and boasts a large trunk. The Lincoln MKZ comes standard with front-wheel drive and a V6. A sports suspension package and all-wheel drive are available for sportier handling and all-weather capability.

The new 2011 Lincoln MKZ Hybrid is a four-cylinder gas-electric model that trades some straight-line performance for an exceptional EPA-estimated 41 mpg City and 36 mpg Highway. The Hybrid is priced identically to the V6 model and comes with all the same standard equipment. We found the Lincoln MKZ Hybrid easy to drive and operate. It's smooth, sophisticated and refined. The Hybrid employs a four-cylinder engine and an electric motor. (You do not plug it in.)

We found the Lincoln MKZ stable and calm through the corners. The all-wheel-drive sports model has a driving performance envelope that overlaps that of sporty cars. The standard V6 revs to 6750 rpm and we found engine and transmission responsive when called upon. The MKZ is more of a luxury car than a sporty car, but it can accelerate from 0-60 mph in 7.1 seconds, which is reasonably quick.

2011 Bentley Mulsanne

June 8th, 2011 Comments Off

Bentley's most recent flagship, the Mulsanne, made its debut at Pebble Beach last summer and goes into production this summer; the manner of construction and a final assembly check involving 503 points that requires more than two hours' time hardly qualify it as a production car.

For their strength and power W.O. Bentley's cars were once described as the world's fastest trucks. While the Mulsanne doesn't have the scale and bluntness of the aircraft-carrier-like prow on Rolls-Royce's Phantom it is still a big car, a foot longer than a long-wheelbase Mercedes S-Class and just three inches shorter than a Chevrolet Suburban. Luxury isn't light either, the Mulsanne weighing in at 5700 pounds, and extended-wheelbase versions may follow in the future.

Mercedes-Benz SLS AMG Roadster

June 5th, 2011 Comments Off

Stuttgart, Germany - AMG performance Mercedes-Benz has released details of its latest SLS AMG Roadster.

This super sports car combines open-top driving with outstanding driving dynamics and a systematic lightweight construction.

Powering the SLS AMG Roadster is a 6.3-litre V8 ( same as gull-wing model) that produces 420kW at 6800rpm and 650Nm of torque at 4750rpm. The open-top SLS AMG accelerates from zero to 100 km/h in 3.8 seconds, and the top speed is 317km/h (electronically limited).

The SLS AMG Roadster consumes 13.2-litres per 100 kilometres (NEDC combined) and producing 308 grams per kilometre of CO2 emissions.

The Roadster's 6.3-litre V8 is mated to an AMG Speedshift DCT 7-speed sports transmission that boasts fast gear changes with no loss of traction - in as little as 100milliseconds. The driver has a choice of four different driving modes: 'C' (Controlled Efficiency), 'S' (Sport), 'S+' (Sport plus) or "M" (Manual).

The compact fabric soft top of the SLS AMG Roadster opens and closes in just eleven seconds, and can be operated on the move at speeds up to 50km/h.

The interior features an aircraft inspired cockpit: prominent stylistic features include the dashboard in the shape of a wing section and the air vents with adjustable, cruciform nozzles reminiscent of jet engines. The extended centre console of matt, solid metal and the new E-SELECT lever in the shape of an aircraft's thrust control are also design features adopted from the world of aviation. Another discreet, fine detail is the embossed AMG emblem on the leather-lined selector lever.
