Mercedes McLare

The Mercedes McLaren is an Anglo-German grand tourer car jointly developed by Mercedes-Benz and McLaren Automotive, built in Portsmouth and the McLaren Technology Centre in Woking, Surrey, England and sold from 2003 to 2009. When it was developed, Mercedes-Benz owned 40 percent of the McLaren Group.

Due to the automatic gear box, front mid-engined arrangement, and its driving characteristics, some commentators classify the SLR McLaren as a GT, whose rivals would be vehicles such as the Aston Martin DBS V12 and Ferrari 599 GTB Fiorano.

SLR stands for "Sport, Leicht, Rennsport" (sport, light, racing). Mercedes-Benz stated that they would build 3,500 SLRs over seven years, with an annual production of 500 cars. The car's base price, GB£ 295,337 (approx. US$ 450,000, € 350,000, CHF 500,000 or C$ 500,000. 2009), made it the ninth most expensive street-legal car in the year 2008.

The Mercedes McLaren was inspired by the Mercedes-Benz 300 SLR Uhlenhaut Coupe & Racecar of 1955, which was a modified Mercedes-Benz W196 F1 race car. It was introduced on 17 Nov 2003. On 4 April 2008, Mercedes announced they would cease production of the SLR. The last of the coupes rolled off the production line at the end of 2007 and the roadster version was discontinued in early 2009.

The SLR sports a 232 kg (510 lb) hand-built 5,439 cc (5.439 L; 331.9 cu in), supercharged, all-aluminium, SOHC V8 engine. The cylinders are angled at 90 degrees with three valves per cylinder and lubricated via a dry sump system. The compression ratio is 8.8:1 and the bore and stroke is 97 millimetre (3.82 in) and 92 millimeters (3.62 in), respectively. The Lysholm-type twin-screw supercharger rotates at 23000 revolutions per minute and produces 0.9 bar (13 psi) of boost. The compressed air is then cooled via two intercoolers. The engine generates a maximum power of 626 PS (460 kW; 617 hp)@6500rpm and maximum torque of 780 N·m (580 lb·ft)@3250-5000rpm.

Unlike most of its contemporaries, its engine is front-mid mounted. McLaren took the original concept car designed by Mercedes and moved the engine 1 metre (39.4 in) behind the front bumper, and around 50 centimetres (19.7 in) behind the front axle. They also optimized the design of the center firewall.

The SLR uses AMG SPEEDSHIFT R 5-speed automatic transmission with 3 manual modes. For durability Mercedes selected a 5-speed transmission rather than their 7-speed gearbox which was more complex and used more parts

The car uses carbon fibre for its entire body construction in an attempt to keep the weight low. Despite CFRP materials the total curb weight is 1,750 kg (3,858 lb).

Car and Driver achieved a 0-60 mph (100 km/h) time of 3.4 seconds, and a quarter-mile time of 11.2 seconds at 130 mph (209 km/h) C&D suggests the times may be even lower if temperatures were lower. Motor Trend tested the SLR and achieved a 0-60 mph time of 3.3 seconds in April 2006. Car and Driver achieved top gear acceleration 30-50 mph and 50-70 mph times of 1.7 and 2.4 seconds, which are the fastest ever recorded by the magazine in a production car. The SLR also pulled 1.13 g on the skidpad.

Road and Track tested the car in their July 2005 Road Test and reached 60 mph (97 km/h) from a standstill in 3.5 seconds. The 0 - 100 mph (160 km/h) sprint was achieved in 7.5 seconds and a quarter mile run was completed in 11.5 seconds at 126 mph (203 km/h).

In June 2004 the SLR was tested at Nardo and performed the 0-100 km/h (62 mph) exercise in 3.8 seconds, 0-200 km/h (124 mph) in 10.7 seconds and 0-300 km/h (190 mph) in 30.6 seconds.

HONDA CRZ

HONDA CRZ

Finally the 2011 Honda CR-Z has come down off the stand at the auto shows and it's sitting right here on the asphalt on Naruto Skyline, a mountain road down the spine of Shikoku, the smallest of the main islands of Japan. We've been waiting to get behind the wheel of the Honda CR-Z since the concept first appeared at the 2007 Tokyo Motor Show, and now we're getting our chance.

                                                 HONDA CRZ

Already there's plenty of hype building for the car's introduction to the U.S. late this summer, as American Honda has already built a Web site to promote the car's arrival. But this is the real car in front of us, ready to be released into the Japanese market, and Honda officials tell us that the American version won't be much different.

                                                   HONDA CRZ

The 2011 Honda CR-Z asks a lot of questions. The recession has dramatically affected Honda's adventurous engineering spirit, and the company has had to sell its Formula 1 team, cancel the development of its new front-engine replacement for the Acura NSX and end the sale of the Honda S2000 in America. Does this company still have the imaginative engineering that makes it so different?

The Honda CR-Z is certainly a different kind of car. A hybrid can be a lot of things. Clean, clever and fuel-efficient, without a doubt, and a poster child for a forthcoming generation of sensible cars. But fun?

Honda has been working hard to make sure that the 2011 Honda CR-Z makes us remember the Honda CR-X, its two-passenger coupe built from 1983-'91. Just as with the CR-X, the mission here has been to build a small, smart, eco-friendly coupe for the modern era. Lightness and efficiency are the key attributes, because the combination of 122 horsepower and a curb weight north of 2,550 pounds tells you the Honda CR-Z is not going to be blowing too many doors off a Bugatti Veyron any time soon.

Here on the Naruto Skyline, the CR-Z defies its critics in cyberspace, who have been quick to dismiss the idea of the first hybrid with a six-speed manual transmission. It proves surprisingly taut, sporty, agile and entertaining as it tackles the twists and turns of the Shikoku roads.Of course, it's a totally different car from the CR-X coupe. That is to say, it's not some kind of cut-down Honda Civic coupe with a manic 1.6-liter VTEC twin-cam engine screaming its way to an 8,000-rpm redline. Nor is it a redo of the original Honda Insight, the slippery 1.0-liter hybrid coupe that Honda launched back in 1999 as the first hybrid to go on sale in the U.S.

Fact is, the 2011 Honda CR-Z falls somewhere between the two — both in terms of design and in the amount of performance on offer. Honda believes that this is the right combination to build a network of  CR-Z enthusiasts from Mini-type buyers who like the idea of a smart premium-style compact, only with the green image that a hybrid conveys.

The Honda CR-Z is like a Tesla Roadster, but without the $109,000 price tag.

While the Honda CR-Z is loosely based on the current four-door Honda Insight sedan, you'll be cheered to know that the Honda engineers have massively improved the formula by shortening the wheelbase, widening the front and rear track and making the structure far more rigid.

The car measures 160.6 inches from end to end, 68.5 inches wide and only 54.9 inches to the tip of its antenna. The wheelbase is 95.8 inches, some 4.6 inches shorter than the Insight, and the Honda CR-Z retains the suspension of the Insight platform with front MacPherson struts and a rear torsion-beam setup. The bad news is, Honda claims only a 97-pound reduction in weight from the Insight sedan.

Once you pull open the somewhat heavy door, a novel interior design awaits, a kind of cost-conscious, Honda-type attempt to deliver the arty style of a Mini or Fiat 500. The low-set driving position is just what you want in a performance car, and the pedals and shift lever feel perfectly placed. The sport seat offers fine all-around support and looks good. The instrument panel is a busy mass of buttons, lights and switches, but there are cool touches like the usual entertaining display of power flow through the internal combustion engine and hybrid system.

Don't look back, though, because rear vision is badly hampered by that dramatic, sloping roof line, especially into the blind spots over your shoulders. In Japan, the Honda CR-Z comes as a 2+2 with kid-size jump seats behind you, but the new small Honda will be strictly a two-passenger vehicle in the U.S.

Lexus IS

Lexus IS

If you're shopping for an entry-level luxury sedan with a sporty disposition, you'll undoubtedly come across the compact Lexus IS 250. Although modestly powered for a premium-brand sport sedan, the Lexus IS 250 offers all the other virtues of the current IS series, including precise handling, a top-quality interior and an extensive array of high-tech features.

Lexus IS

In addition, the Lexus IS 250 has typically offered a wider variety of drivetrain configurations than the more potent IS 350. On the standard rear-wheel-drive sedan, the company gives you a choice of a six-speed manual or a six-speed automatic transmission. If you've settled on the automatic, you have the option to order your Lexus IS 250 with all-wheel drive.

Lexus IS

Choices are many in the highly competitive entry-luxury sedan market. The Lexus IS 250 is a respectable pick, but its lack of serious speed will deter hard-core enthusiasts, as will its muted steering feedback. And in terms of comfort, a cramped backseat means it won't be the best choice for families or those who frequently take on passengers.

Current Lexus IS 250


Lexus sells the IS 250 in a single trim level, with either rear-wheel drive or all-wheel drive. For power, the 250 comes with a 2.5-liter V6 rated for 204 horsepower and 185 pound-feet of torque. Rear-drive models can be had with a six-speed manual transmission or a six-speed automatic, while the AWD car is only available with the automatic.

The standard equipment list includes 17-inch alloy wheels, keyless ignition/entry, power front seats, leather upholstery and a 13-speaker sound system. Major options include xenon headlights, heated/ventilated front seats, a Mark Levinson surround-sound audio system, a navigation system and an F Sport package that includes a sport-tuned suspension and sport seats.

On the move, the Lexus IS 250 is smooth-riding and quiet but a bit light on emotion. Handling is secure and precise, particularly with the sport package fitted, but the IS never communicates with its driver the way a BMW 3 Series sedan does. Otherwise, the Lexus IS 250's dynamics are certainly on par with the other leading entry-luxury sedans. Acceleration is adequate for a car in this price range, but with 0-60-mph estimates falling around the 8-second mark, we'd hardly call it pulse-quickening.

Inside, the leather-lined Lexus IS 250 feels luxurious even in standard spec -- something that can't be said of many entry-level luxury sedans in this price range. Seat comfort and passenger room are excellent up front, but the backseat offers considerably less legroom than most competing luxury sport sedans do.
