BMW M135i vs Mercedes AMG A35 vs Mini Clubman JCW
For years now, #BMW has been insisting that the vast majority of 1-Series customers are not worried about whether the engine drives the front or rear wheels. It would therefore be a shame for the same customers that the new 1-Series switched to front-wheel drive, unless in that case as #M135i ... which is now systematically linked to the xDrive four-wheel drive. What about the sporty temperament without the typical driving behavior of a rear-wheel driver? And what driving sensations can we expect from a chassis that is ultimately designed for a front wheel tractor? Does the 135i actually deserve its M badge? These are all questions we try to answer based on a comparative test of BMW's youngest sportsman with two of his biggest competitors: the #Mercedes-#AMG A 35 4Matic and the #Mini #Clubman JCW All4.
The changeover to the BMW front-wheel-drive architecture is reflected in the new proportions and flowing, elongated lines of the all-new BMW 1-Series. The shorter bonnet melts into the windscreen, while the long roofline drops away slightly towards the rear. A wide tail with an athletic shoulderline above the rear wheel arches emphasises the car's powerful, sporty presence when viewed from behind. At the same time, the compact body offers significantly more space within a footprint almost identical to the predecessor model's and so makes the car even more versatile in everyday use. At 4,319 millimetres, the new BMW 1-Series is five millimetres shorter than its predecessor. In terms of width (now 1,799 millimetres), this third-generation model has grown by 34 millimetres while its height (1,434 mm) has increased by 13 millimetres. At 2,670 millimetres, the wheelbase is 20 millimetres shorter than that of the predecessor model.
Of the various engines available for the new BMW 1-Series, it is the newly developed four-cylinder unit under the bonnet of the BMW M135i xDrive that really steals the show. It is the BMW Group's most powerful four-cylinder engine, extracting 225 kW (306 hp) from its 2.0-litre displacement between 5,000 and 6,250 rpm with the help of BMW TwinPower Turbo technology. Its peak torque of 450 Nm (332 lb-ft) comes on stream at 1,750 rpm and stays there up to 4,500 rpm. The flagship model races to 100 km/h (62 mph) from rest in just 4.8 seconds (4.7 seconds with M Performance package, available from 11/2019), while top speed is limited to 250 km/h (155 mph). Despite such breathtaking performance figures, the BMW M135i xDrive makes do with 7.1 - 6.8 litres of fuel per 100 kilometres (39.8 - 41.5 mpg imp) on the combined cycle and emits just 162 - 155 grams of CO2 per kilometre.
Emotional, agile and digital: with the A35 4MATIC Mercedes-AMG is presenting a completely new entry-level model to the world of driving performance. It is based on the new Mercedes compact vehicle platform and is powered by a new 2.0-litre four-cylinder turbo engine with output of 225 kW (306 hp). Body shell, suspension, all-wheel drive, transmission, drive programs, fine tuning - every detail has been designed for maximum driving dynamics without compromising on everyday comfort. The performance at sports car level (acceleration 0-100 km/h in 4.7 seconds) and the specific design also strengthen its identity as a member of the performance family. A true AMG for the Hot Hatch stage!
The AMG SPEEDSHIFT DCT 7G dual-clutch transmission also contributes to the agile and dynamic character of the new A35 4MATIC. The gear ratios have been configured so that the driver experiences very spontaneous acceleration in all speed ranges, combined with fast shifting and optimum connections when shifting up. The standard RACE-START function allows maximum acceleration from stationary and is a highly emotional experience. The functions of the AMG SPEEDSHIFT DCT 7G transmission are rounded off with a temporary M mode activated by operating the steering wheel shift paddles in any driving mode, and with the manual transmission mode "M" for manual gear shifting with the shift paddles.
As the power source for extreme driving fun, the comprehensively redesigned 4-cylinder engine has been consistently oriented towards maximum output. It is based on the 2.0 litre drive from the MINI Cooper S Clubman and MINI Cooper S Countryman but has now undergone model-specific modifications to the crankshaft drive and also benefits from the latest generation of MINI TwinPower Turbo technology. These modifications are based on the John Cooper Works' racing know-how and comprise a reinforced crankshaft, a main bearing with an extended cross-section, specific pistons, connecting rods, and a new vibration damper with optimised cooling.
The high-performance drive of the new MINI John Cooper Works Clubman and the new MINI John Cooper Works Countryman generates a maximum torque of 450 Nm in the broad engine speed range between 1 750 and 4 500 rpm, which is around 28 percent higher than that of the previous engine. The maximum output of the new 4-cylinder engine has been increased by approximately 32 percent. The new top level of 225 kW/306 hp is reached between 5 000 and 6 250 rpm. The resulting pulling power enables the new engine of the MINI John Cooper Works Clubman to produce an acceleration performance of 0 to 100 km/h in 4.9 seconds, while the figure for the new MINI John Cooper Works Countryman is 5.1 seconds, ensuring an impressive level of elasticity during spontaneous speed bursts. For the first time with MINI vehicles, the maximum speed of the new top sports performer is now electronically limited to 250 km/h.

這款大家應該都很熟,原為二戰運輸機C-47原,在1960年代越戰期間,改裝成空中砲艇「AC-47」,代號「幽靈」(Spooky),綽號被稱「噴火神龍」(Puff, the Magic Dragon,出自1963年發表的美國流行歌曲〈魔法龍帕夫〉)
美軍在C-47的兩個窗開口上,以及所有左側的貨艙門上安裝3挺M134機槍(Minigun),其主要功能是為地面部隊實行近距空中支援,可以提供綿密的火網支援,有效火力覆蓋約為一個平均直徑47.5公尺的微橢圓面,由於在越南戰場上得到實戰驗證,獲得駐越美軍的尊敬與仰賴,這也是美軍首個空中砲艇的始祖
#VietnamReviited
The Douglas AC-47 Spooky (also nicknamed "Puff, the Magic Dragon") was the first in a series of gunships developed by the United States Air Force during the Vietnam War. It was designed to provide more firepower than light and medium ground-attack aircraft in certain situations when ground forces called for close air support.
In August 1964, years of fixed-wing gunship experimentation reached a new peak with Project Tailchaser under the direction of Capt. John C. Simons. This test involved the conversion of a single Convair C-131B to be capable of firing a single GAU-2/A Minigun at a downward angle out of the left side of the aircraft. Even crude grease pencil crosshairs were quickly discovered to enable a pilot flying in a pylon turn to hit a stationary area target with relative accuracy and ease. The Armament Development and Test Center tested the craft at Eglin Air Force Base, Florida, but lack of funding soon suspended the tests. In 1964, Capt. Ron W. Terry returned from temporary duty in Vietnam as part of an Air Force Systems Command team reviewing all aspects of air operations in counter-insurgency warfare, where he had noted the usefulness of C-47s and C-123s orbiting as flare ships during night attacks on fortified hamlets. He received permission to conduct a live-fire test using the C-131 and revived the side-firing gunship program.
By October, Capt. Terry's team under Project Gunship provided a C-47D, which was converted to a similar standard as the Project Tailchaser aircraft and armed with three miniguns, which were initially mounted on locally fabricated mounts—essentially strapped gun pods intended for fixed-wing aircraft (SUU-11/A) onto a mount allowing them to be fired remotely out the port side. Captain Terry and a testing team arrived at Bien Hoa Air Base, South Vietnam, on 2 December 1964, with equipment needed to modify two C-47s. The first test aircraft (43-48579, a C-47B-5-DK mail courier converted to C-47D standard by removal of its superchargers) was ready by 11 December, the second by 15 December, and both were allocated to the 1st Air Commando Squadron for combat testing. The newly dubbed "FC-47" often operated under the radio call sign "Puff". Its primary mission involved protecting villages, hamlets, and personnel from mass attacks by VC guerrilla units.
Puff's first significant success occurred on the night of 23–24 December 1964. An FC-47 arrived over the Special Forces outpost at Tranh Yend in the Mekong Delta just 37 minutes after an air support request, fired 4,500 rounds of ammunition, and broke the Viet Cong attack. The FC-47 was then called to support a second outpost at Trung Hung, about 20 miles (32 km) away. The aircraft again blunted the VC attack and forced a retreat. Between 15 and 26 December, all the FC-47's 16 combat sorties were successful. On 8 February 1965, an FC-47 flying over the Bong Son area of Vietnam’s Central Highlands demonstrated its capabilities in the process of blunting a Viet Cong offensive. For over four hours, it fired 20,500 rounds into a Viet Cong hilltop position, killing an estimated 300 Viet Cong troops.
The early gunship trials were so successful, the second aircraft was returned to the United States early in 1965 to provide crew training. In July 1965, Headquarters USAF ordered TAC to establish an AC-47 squadron. By November 1965, a total of five aircraft were operating with the 4th Air Commando Squadron, activated in August as the first operational unit, and by the end of 1965, a total of 26 had been converted. Training Detachment 8, 1st Air Commando Wing, was subsequently established at Forbes AFB, Kansas. In Operation Big Shoot, the 4th ACS in Vietnam grew to 20 AC-47s (16 aircraft plus four reserves for attrition).
The 4th ACS deployed to Tan Son Nhut Air Base, Vietnam, on 14 November 1965. Now using the call sign "Spooky", each of its three 7.62 mm miniguns could selectively fire either 50 or 100 rounds per second. It can be seen in action here. Cruising in an overhead left-hand orbit at 120 knots air speed at an altitude of 3,000 feet (910 m), the gunship could put a bullet or glowing red tracer (every fifth round) bullet into every square yard of a football field-sized target in potentially less than 10 seconds. And, as long as its 45-flare and 24,000-round basic load of ammunition held out, it could do this intermittently while loitering over the target for hours.
In May 1966, the squadron moved north to Nha Trang Air Base to join the newly activated 14th Air Commando Wing. The 3rd Air Commando Squadron was activated at Nha Trang on 5 April 1968 as a second AC-47 squadron, with both squadrons redesignated as Special Operations Squadrons on 1 August 1968. Flights of both squadrons were stationed at bases throughout South Vietnam, and one flight of the 4th SOS served at Udorn Royal Thai Air Force Base with the 432nd Tactical Reconnaissance Wing. The superb work of the two AC-47 squadrons, each with 16 AC-47s flown by aircrews younger than the aircraft they flew, was undoubtedly a key contributor to the award of the Presidential Unit Citation to the 14th Air Commando Wing in June 1968.
One of the most publicized battles of the Vietnam War was the siege of Khe Sanh in early 1968, known as "Operation Niagara". More than 24,000 tactical and 2700 B-52 strikes dropped 110,000 tons of ordnance in attacks that averaged over 300 sorties per day. During the two and a half months of combat in that tiny area, fighters were in the air day and night. At night, AC-47 gunships kept up a constant chatter of fire against enemy troops. During darkness, AC-47 gunships provided illumination against enemy troops.
The AC-47D gunship should not be confused with a small number of C-47s which were fitted with electronic equipment in the 1950s. Prior to 1962, these aircraft were designated AC-47D. When a new designation system was adopted in 1962, these became EC-47Ds. The original gunships had been designated FC-47D by the United States Air Force, but with protests from fighter pilots, this designation was changed to AC-47D during 1965. Of the 53 aircraft converted to AC-47 configuration, 41 served in Vietnam and 19 were lost to all causes, 12 in combat. Combat reports indicate that no village or hamlet under Spooky Squadron protection was ever lost, and a plethora of reports from civilians and military personnel were made about AC-47s coming to the rescue and saving their lives.
As the United States began Project Gunship II and Project Gunship III, many of the remaining AC-47Ds were transferred to the Vietnam Air Force, the Royal Lao Air Force, and to Cambodia's Khmer Air Force, after Prince Norodom Sihanouk was deposed in a coup by General Lon Nol.
A1C John L. Levitow, an AC-47 loadmaster with the 3rd SOS, received the Medal of Honor for saving his aircraft, Spooky 71, from destruction on 24 February 1969 during a fire support mission at Long Binh. The aircraft was struck by an 82-mm mortar round that inflicted 3,500 shrapnel holes, wounding Levitow 40 times, but he used his body to jettison an armed magnesium flare, which ignited shortly after Levitow ejected it from the aircraft, allowing the AC-47 to return to base. #Phoenix
