2022 Porsche 911 GT3 tested at 186 mph for over 3,000 miles

2022 Porsche 911 GT3

When developing its new 2022 Porsche 911 GT3, engineers drove a prototype at a sustained 186 mph for a distance of approximately 3,100 miles, only coming to a stop whenever the car needed refueling.

The test, which took place at Italy’s Nardo high-speed circuit, which Porsche happens to own, was just one of several key durability tests for the car, and in particular its 4.0-liter flat-6 engine. In fact, testing of the engine was even more rigorous. We’re sure Porsche is still mindful of the engine fires that plagued early examples of the previous-generation 911 GT3.

In addition to the high-speed Nardo run, the engine in the new GT3 racked up more than 22,000 hours on Porsche’s test rig. During these tests, the engineers repeatedly simulated runs the engine would experience at major racetracks, with the engine pressed to full throttle for a high proportion of the time, according to Porsche.

Luckily for the engineers, they had a good starting base as the engine in the GT3 is closely related to the unit used in the 911 GT3 R race car and almost identical to the one in the slightly tamer 911 GT3 Cup racer.

In the GT3, the engine generates a peak 502 hp and 346 lb-ft of torque and willingly revs to 9,000 rpm. The output might not seem like much compared to modern supercars, but it’s enough to hurtle the GT3 around the Nürburgring in under seven minutes.

The engine also features dry-sump lubrication but skips electronically controlled mounts as these were deemed to be not worth the added weight. It also offers sharp throttle response thanks to six independent throttle bodies, and it can be had with either a 6-speed manual or 7-speed dual-clutch unit, with the manual more popular with buyers, at least here in the United States.

Of course aerodynamics also has a major role to play in the performance of the GT3 (if in doubt, just take a look at the car’s swan-neck rear wing). As a result, the car has spent more than 160 hours in the wind tunnel. Why so long? Because the engineers don’t only test the car heading in straight line. They simulate every conceivable driving situation, adjusting the roll, pitch and yaw in order to simulate the different situations the car might experience on a track.

In the new GT3, both the rear wing and front splitter have four levels of adjustment. This will allow owners to switch between street and performance setups. The latter increases downforce by up to 150% over the outgoing GT3, and even the street setup generates about 50% more downforce than in the previous generation.

The new GT3 is due at dealerships in the fall with a starting price of $162,350. Also in the works is a more civilized GT3 Touring, as well as a more hardcore GT3 RS.

2021 Ford Mustang Mach 1, 2021 Mercedes-Benz AMG GLB35, 2024 GMC Hummer EV SUV: This Week’s Top Photos

Published

on

2021 Mercedes-Benz AMG GLB35

Ford may have just launched an electric Mustang crossover but old-school muscle car fans have their own Mustang model to look forward to in 2021, and it’s wearing the Mach 1 badge. The car is a fantastic mash-up of GT350 and Bullitt parts, and we’ve got a full review up.

2021 Mercedes-Benz AMG GLB35

Another vehicle we tested this week was the 2021 Mercedes-Benz AMG GLB35. This compact crossover has 302 hp, third-row seats, and loads of tech, and it’s quite reasonably priced at about $50,000.

2022 Mercedes-Benz CLS-Class

Another Mercedes in the headlines this week was the updated 2022 CLS-Class. The latest updates bring revised styling inside and out, plus some new technology, but sadly there’s no longer an AMG option for U.S. customers.

Pagani built just five examples of its Zonda Revolucion track special early last decade, and this week we learned that one of them has been made legal on the street. The conversion to a road car was handled by the folks at Lanzante, which has performed similar conversions in the past for track cars like the McLaren P1 GTR.

For fans of electric vehicles, GMC unveiled the 2024 Hummer EV SUV. The SUV shares its platform and powertrain with the Hummer EV pickup truck, but the wheelbase is shorter and the design has some strong H3 vibes. While the pickup starts production this fall, the SUV won’t show up until spring 2023.

Another new vehicle that made its debut this week was the 2022 Toyota 86. The second-generation sports coupe is once again a twin with the Subaru BRZ, and like the BRZ it gets a 2.4-liter flat-4, rear-wheel drive, and a choice of manual or automatic transmissions.

You can now get the looks and performance of Ford’s Explorer ST for about $4,000 less. The Blue Oval this week revealed a new Explorer Enthusiast ST for the 2021 model year with the same 400-hp powertrain as the regular Explorer ST but minus some of the vehicle’s luxury items.

Porsche will keep the current Macan on sale when a new battery-electric version of the crossover arrives in 2022, but there will be some updates made to it. As our latest spy shots reveal, the current Macan will receive a few tweaks that will likely align its styling and tech with the forthcoming electric Macan.

2021 Mercedes-Benz E450 Cabriolet drives a second wind

Published

on

2021 Mercedes-Benz E450 cabriolet

When the days were really short last winter, and the pre-vaccine despair had set in, I got some welcome relief in the form of the 2021 Mercedes-Benz E450 Cabriolet. Call it naturopathy, but in the dark days before Pfizer and Moderna became vernacular, the Cabriolet came to play here in the Gulf of Mexico’s backyard, just in time for the lyrical 70-degree days that flagrantly defy winter.

The Cabriolet came just in time to give me a social-distancing second wind, and a second shot at the aborted summer of 2020. Here’s where it cured my seasonal blues—and where needed its own remedies.

2021 Mercedes-Benz E450 cabriolet

Hit: Mild-hybrid, served up purely smooth. 

A 362-hp mild-hybrid 3.0-liter turbo-6 and effortless 9-speed automatic powered this all-wheel-drive Cabriolet. I wasn’t convinced that the changeover in powertrains would do much for the E-Class, but the new inline engine family spreads torque as smoothly as speculoos, and its mild-hybrid system gives it effortless low-end power and excellent gas mileage for its size.

Miss: Back seat space is slim. 

We’d spend days in the Cabrio’s multi-adjustable cooled front seats; they’re fabulous. The back seat, not so much. Two adults slipped into the back seat of the Cabriolet, but neither wanted a repeat performance. Medium-size passengers will do fine for short sunset runs down the shore road, but for the three-hour round-trip to Costco, you’ll want to borrow a friend’s SUV.

Hit: The look.

The mid-size Mercedes convertible and coupe have polished their shapes to near-perfection. (We’ve driven the Benz E450 Coupe up north; it looks good even in salt spray.) The E450 Cab fits in at the BBQ stand and the show-off spot in front of the club. Where it fits in best is the empty gulf-front drive where the only things keeping pace are rare birds and a gentle breeze. With a diamond-flecked grille, sharp LED eyebrows, and stylish AMG Line wheels, the E450 Cabriolet profiles in the only good and acceptable way.

Miss: Touchpads on steering wheel and screens on the dash.

Haters live among us and they say the E450’s touchscreens and steering-wheel touchpads are misses. They either too small or too inexpensive-looking or too sensitive or something else we heard but didn’t absorb. Sure, they may be flawed—but flaws aren’t always fatal. In my Cabriolet tester’s case, the Insignia-esque look of the displays was offset with open-pore wood and red-and-black leather.

Hit: “Hey, Mercedes.”

 The E450 doesn’t mind being a hollaback girl. Say “Hey, Mercedes” and it responds to a wealth of natural language commands that can change audio functions, find your favorite podcast, choose a new route around paralytic hurricane-induced traffic, and find a coffee spot with patio seating.

Hit: Top-down details.

The power-folding roof can go away in under 20 seconds and at speeds of up to 30 mph, but the E450 Cabriolet also has sun-reflecting leather, the Airscarf neck-warming vents, and a wind deflector, all standard.

2021 Mercedes-Benz E450 cabriolet

Hit: In touch with safety.

The E450 Cabrio gets standard automatic emergency braking, blind-spot monitors, a surround-view camera system, and automatic parking assistance. This one came also with a Driver Assistance Package with adaptive cruise control that reduces the speed for curves, traffic sign recognition that adjusts cruise control speed, active lane control, and automatic lane changes at the tap of the turn-signal stalk. The Benz systems have been some of the best since their introduction and their fluid and precise supplemental behavior lets drivers take a second away from the controls.

Hit: It’s well stocked.

The E450 comes standard with navigation, Apple CarPlay and Android Auto, wireless smartphone charging, heated front seats, spectacular Burmester sound, and 18-inch alloy wheels with all-season tires. Spend up to the AMG Line trim if you want, but don’t miss out on the cooled multi-contour front seats or the high-wattage low-gloss wood trim.

Lime Rock Park has new ownership

Published

Lime Rock Park

One of America’s oldest and most revered road-racing courses, Lime Rock Park, located in the northwest corner of Connecticut, has been sold by Skip Barber to a group that includes former Airstream president Dicky Riegel, who will serve as the track’s new chief executive.

“Lime Rock has been one of my favorite places and my home track for over 40 years; the same is true for my partners, Charles (Mallory) and Bill (Rueckert), both of whom consider Lime Rock a home away from home,” Riegel is quoted in the announcement of the sale.

“All of us have deep roots in Connecticut and look forward to being active in the community and working collaboratively with the Town. To now be owners of this iconic and storied brand is a dream come true.”

Lime Rock Park

Skip Barber, the racing school founder who has owned the track for nearly 40 years, will remain part of the new ownership team, according to the announcement. He said the new ownership group brings “outstanding new vision and vitality to Lime Rock’s operations and to our local and regional community. They are the ideal stewards of the Park’s long and successful legacy.”

The race track, which is listed on the National Register of Historic Places, is a challenging 1.5-mile circuit founded in 1956 by Jim Vaill with design help from racer John Fitch and the Cornell Aeronautical Laboratory and was the first track built using highway-safety principles. The first race was staged in April 1957.

A quirk of the track’s scheduling is a local ordinance that bans racing on Sundays, which enables the track to feature a schedule with Friday, Saturday, Monday holiday racing events with car shows on Sundays.

The track also is known for buildings designed by auto racer and architect Sam Posey.
